The need for detoxification of less utilized crops with similar nutritional composition with soybeans
as potential substitute or supplement for soybeans in conventional feeds production is obvious as price of
soybean continue to rise. Jatropha curcas is one of such crops which can serve as a potential source of dietary
energy and protein. However, the presence of anti-nutritional factors restricts the utilization of the Jatropha
curcas seed in animal feed. Several researchers however have shown that this obstacle can be overcome by
detoxifying the seeds, but many of them failed to established the effects of these detoxification methods on the
nutritional content of Jatropha curcas .The main objective of this study therefore was to determine the effect of
three simple inexpensive physical methods of detoxification (soaking, roasting and fermentation) on the
proximate and toxicological compositions of Jatropha curcas seed meal. To achieve this, Jatropha curcas seeds
sample used were divided into four parts. The first three parts were subjected to the three different physical
treatments after which they were dried to constant weight and while the fourth part was dried to constant weight
and milled. These four samples were then analysed for their proximate and toxicological composition .The
results showed that fermentation deactivated the antinutrients most in the seeds and did not adversely affect the
nutritional composition of the seeds

A REVIEW ON APPLICATIONS OF BIOSURFACTANTS PRODUCED FROM UNCONVENTIONAL INEXP...SUS GROUP OF INSTITUTIONS
Biosurfactants can serve as green alternative in different areas due to
their ecological acceptance as they are biodegradable and nontoxic.
Nowadays biosurfactants are predominantly used in pharmaceutical,
oil industry, and for the bioremediation of pollutants. Apart from these,
biosurfactants also show potential applications in many sectors of food
industry and agriculture. Allied with emulsion forming and breaking,
antiadhesive, functional ingredient, are some properties that can be
exploited in agro-food biotechnology. Potential role of biosurfactants
in food and agricultural sectors as well as present concern of lowering
the production cost of biosurfactants by using the unconventional
wastes as substrate is discussed in this article.
— The present study evaluated physico-chemical and sensorial qualities of value added banana products. Unripe fruits of Cavendish variety were processed for making banana flour. Value added products like dough, chapatti and banana kheer were prepared from banana flour. Rice and basin flour were also used in chappati. Unripe banana fruit, banana flour and their products were analysed for pH, titratable acidity, moisture (%), TSS (Brix) and vitamin C. The results showed that the maximum pH (7.68) and TSS (26.30 brix) recorded from the kheer, However, Ash (0.86%) and vitamin C (18.3mg/100gm) were observed highest in chapatti prepared from banana and rice flours as compared to chappati prepared from banana flour only (12.54). Unripe banana fruits had maximum percentage of moisture (72.08%) in comparison to banana products. The minimum pH (6.79) and titratable acidity (0.02) were observed from the unripe banana fruits. While, banana flour had minimum moisture (7.49%). Minimum TSS (5.30) were recorded in chappati prepared from mixture of banana-rice flour and banana-basin flour. The results shows that processing of banana for value added products alter the physico-chemical qualities of banana.
Proximate and Microbial Profile of Couscous Yoghurt Produced from Soya MilkIJEAB
This study investigated the effect of milk type and mixture ratio on the proximate composition and microbial profile counts of couscous yoghurt. Yoghurts were first made from cow milk (CM), soya milk (SM) and equal mixture of both types of milk at ratio 50:50. Couscous was then mixed with yoghurts from cow milk (CMCY); soya milk (SMCY) and cow-soya milk (CSCY) at ratios of 90:10, 80:20 and 70:30 (yoghurt: couscous), w/w for the three respectively. The experiment was designed based on 2 factors (milk type and mixing ratio) at 3 levels, each resulting in a total of 9 treatments. Cow milk yoghurt without couscous was used as the control. Proximate compositions were determined using standard methods. Total viable microbial counts of samples were also determined. There were significant differences (p<0.05) in the proximate composition and CSCY at ratio 70:30 had the highest crude protein. In addition, CMCY at ratio 90:10 recorded the highest mean value for fat, while SMCY at ratio 80:20 and 70:30 recorded the least mean value for fat. All the couscous yoghurt samples had total viable cell counts of (<9 log CFU) that are within the acceptable range according to Codex Standards. In conclusion, the study has shown that CSCY at 70:30 had the highest nutrient content. Moreover, the products were also found to have low levels of microbial profile.
Effect of Different Drying Methods on Chemical Composition of Unripe Plantain...YogeshIJTSRD
Food processing is often thought to bring about changes in nutrients content, thus decreasing its patronage. To investigate this in a Nigerian staple, unripe plantain Musa paradisiaca flours were prepared following sun drying and oven drying methods. These were compared against fresh plantain for their nutritional composition. Proximate composition and minerals contents were determined using standard AOAC methods. The results showed that the unripe plantains pulp contained 59.77 , 1.42 , 1.51 , 1.40 , 7.65 , 28.23 , 40.22 and 38.80 of moisture, ash, fat oils, crude fibre, crude protein, carbohydrates, dry matter and organic matter respectively. Calcium, sodium, potassium, iron, and nitrogen were determined to be 0.1534 ppm, 0.2613 ppm, 0.3034 ppm, 0.7808 ppm and 0.2240 ppm respectively. The processing methods produced flour with similar nutritional composition. However, oven drying gave the lowest moisture content in the flour, suggesting a higher capacity to prevent microbial growth and decay in the dried sample, hence prolonging storage life. Segilola, V.

A Study on the Removal of Pesticide Residues on Potatoes Using Moringa oleife...AI Publications
Moringa oleifera (MO) is a plant whose seeds possess strong coagulation properties capable of removing turbidity and heavy metals from water. In this study, the effectiveness of MO seeds as a potential pesticide removal apparatus for agricultural produce was investigated. The parameters of interest for each pesticide washing solution were pesticide-concentration reduction, cost, and taste alteration to the potatoes. Separate doses of 0.25 mL profenofos 500 EC were individually applied to distinct 250 g pesticide-free potato piles. A submersion of each tainted potato pile was carried out in one of the chosen pesticide baths (mineral water, 2% salt solution, 10% salt solution, vegetable bath wash, and 10 g MO seed) for 10 min, followed by a 10 second mineral water bath rinse. Remaining profenofos residue concentrations on potatoes were quantified using the quick, easy, cheap, rugged, and simple QuEChERs method coincided with High Performance Liquid Chromatography (HPLC). The experiments showed that the MO seed was the most effective at removing profenofos at 52.9% followed by the vegetable bath at 47.3%. Neither method caused an alteration in food taste, but the MO seed method is significantly cheaper at 2,000/L IDR ($0.14 USD) compared to the vegetable bath at IDR 10,668/L ($0.77 USD) at the time of the experiment, respectively.
Evaluation of Antioxidant Phytochemicals in Different Genotypes of PotatoIJERA Editor
Potato (Solanum tuberosum L.) is considered a natural source of phytochemicals that help lower the risk of chronic diseases. Thus, ascorbic acid, total phenolic content and antioxidant activities of Indian potato genotypes were studied. ‘Kufri Pukhraj’ was the best genotype in terms of nutritional components, since it contained the highest amount of ascorbic acid (19.42 mg/100g), and total phenolic content (68.20 mg GAE/100g). Also ‘Kufri Pukhraj’ had the highest DPPH radical scavenging activity of 67.30%. On the other hand, genotype ‘Kufri Chipsona-1’, most commonly used cultivar for processing, displayed the lowest content of total phenolics (31.30 mg GAE/100g) and total antioxidant activity (28.80%). Correlation analysis between total phenolic content and antioxidant activity (r=0.8502) showed a high degree of correlation indicating that these bioactive components contributes to the total antioxidant activity in potato genotypes.
RESIDUAL ESTIMATION OF ISOPROTURON, ATRAZINE AND GRAIN PROTECTANTS IN STORED ...ijabjournal
This study was carried out to see the occurrence and level of pesticide residues in stored wheat grain samples. Wheat grains were collected from different godowns located in Faisalabad district. Weedicide residues in wheat grains were analyzed by using thin plate liquid chromatography and validated high
performance liquid chromatography. On the basis of extent of inhibition of the Hill reaction, it was found that the level of atrazine was (0-0.028 ngkg-1) and the level of isopproturon was (0-0.024 ngkg-1) in test samples. The calculated values were below the Maximum Residue Limit (MEL) i.e. 100 ngkg-1 for atrazine and 2200 ngkg-1 for isoproturon. It was found that presence of herbicide residues in stored wheat was negligible. Further, on wheat grain samples placed in jars and treated with deltamethrin and cypermethrin @0.4 and 0.8% concentration. The persistency data was calculated after 1 hour, 7, 15 and 30 days of treatment. The grain protectants were continuously degraded with the passage of time and after the 30 days
the amount of residues of the grain protectants was found to be very small. It was concluded that the use of the grain protectants in the powder form in combination with other botanicals on stored wheat samples is feasible to reduce the insect pest in stored grains.

Evaluation of fungicides and biological agents for the management of mango an...Agriculture Journal IJOEAR
Abstract— Mango is an important fruit crop in area and production in Gujarat also, where it is cultivated over an area of about 130.1 thousand hectares with annual production of 911.3 thousand tones with productivity of 7.01 tones/ha. Its plantation has become quite popular in the districts of Valsad, Junagadh, Navsari, Kutch, Surat, Amreli and Bhavnagar because of favourable agro-climate condition. Mango is affected by number of diseases at all the stages of its development right from plant in nursery to the fruit in storage or transit. Mango is prone to many fungal diseases like Anthracnose, Rhizopus rot, Stem end rot, Penicillum rot, Black mould rot, Mucor rot, Phyllosticta rot, Pestalotiopsis rot, Macrophoma rot and powdery mildew, leading to heavy loss in yield. Among these diseases, anthracnose is the major disease of mango as it occurs at all the growing parts including leaves, twigs, flowers, fruits except root and trunk throughout the year. Anthracnose caused by Glomerella cingulata (Stoneman) Spauld and H Schrenk (anamorph: Colletotrichum gloeosporioides (Penz.)) appear to be more severe causing devastation of mango fruits during grading, packing, transportation, storage and marketing (Pathak, 1980).
The nutritional composition and fungal spoilage of Dacryodes edulis fruits were carried out in the Department of Forestry/ Environment Laboratory using standard procedures. The experiment was laid out in a Completely Randomized Design (CRD) with six treatments and three replicates. The fungal pathogens isolated from the rotted fruits were Aspergillus niger, Aspergillus flavus, Rhizopus stolonifer, Fusarium pallidoroseum, Botryodiplodia theobromae and Colletotrichum gloeosporioides. The predominant spoilage causing fungi were Colletotrichum gloeosporioides (60%) and Aspergillus niger (52%). Proximate analysis revealed that the affected fruits had significantly reduced (P<0.05) quality when compared to the uninfected fruits in terms of carbohydrate content, protein, oil content, moisture, crude fibre and Ash content. This work holds promise on the importance of the nutritional properties of the fruits in screening for rot tolerance and storage stability.

Genetic Variability for Antioxidant Activity and Total Phenolic Content in Fo...CrimsonpublishersNTNF
Total phenolic content and antioxidant activity were evaluated in 139 diverse genotypes of four pulse crops including 54 genotypes of chickpea (Cicer arietinum), 37 lentil (Lens culinaris), 21 pigeonpea (Cajanus cajan), and 26 blackgram (Vigna mungo). Results indicate significant genotypic variation (p < 0.01) for total phenolic content (TPC) as well as antioxidant activity (AOA). Amongst the four major pulse crops tested, maximum mean phenolic content was recorded in blackgram genotypes (7.01mg GAE/g), followed by lentil (3.46mg GAE/g), pigeonpea (3.32mg GAE/g) and chickpea (2.30mg GAE/g). In general, the Mediterranean landraces of lentil had higher phenolic content as compared to the other lentil varieties and breeding lines. Amongst the chickpea genotypes the phenolic content ranged from 0.40 to 5.63mg GAE/g and comparatively higher value for phenolic content was recorded in desi types (2.67mg GAE/g) as compared to the Kabuli types (1.05mg GAE/g). The antioxidant activity (AOA) was assayed in mature dry seeds utilizing DPPH (2,2-Diphenyl-1-picryl hydrazyl) radical scavenging assay which ranged from 1.73 to 19.14μmole Trolox/g tissue. As observed for TPC, highest AOA was also recorded in blackgram genotypes (19.14μmole Trolox/g tissue), followed by pigeonpea (2.72μmole Trolox/g tissue), chickpea (2.05μmole Trolox/g tissue) and lentil (1.73μmole Trolox/g tissue). Highly significant genotypic as well as phenotypic correlation (p<0.01) was recorded between phenolic content and antioxidant activity in chickpea, lentil as well as blackgram (rG values ranging from 0.268 to 0.850 and rP from 0.253 to 0.817), however, surprisingly the values were non-significant in case of pigeonpea. Strongest genotypic correlation was recorded in chickpea (rG=0.850), followed by lentil (rG =0.744), and blackgram (rG =0.268). High broad-sense heritability (h2bs) (0.89 to 0.97) for phenol content was recorded which indicates that substantial portion of total variation for phenolic content is due to genetic effects.

Effect of Fermentation on the Nutritional and Antinutritional Composition of ...IOSR Journals
The dehulled seeds of three varieties of Lagenaria siceraria were subjected to control fermentation process. The fermented and unfermented seeds were analysed for their nutritional and anti-nutritional compositions using AOAC 1998. The fermented seeds were found to contain high amount of crude protein (48.12%) and crude fibre (4.11%) compared to 27.42% and 0.67% for unfermented seeds respectively. Similarly, crude lipid content of the seeds decreased by about 75%. The process also results in decrease in phytate, oxalate, tannins and cyanide content with consequent increase in nitrate and Vitamin C. Hence fermenting the seeds is an important way of exposing its protein content and reducing the antinutritional content. The seeds were found to have good potentials for preparation of condiments which are commonly used in the preparation of soup.
Evaluation of Nutritional Components of Carica papaya L. At Different Stages ...IOSR Journals
The study compared the nutritive value of Carica papaya L. fruit at different ripening stages with the
aim of advising consumers and biological world when best to consume the fruit. Proximate, mineral and vitamin
analysis were carried out on the pulp, peel and seeds of fruits. Results showed that unripe papaya is a good
source of carbohydrates, vitamins and proteins, and the content decreases as it ripens. Very ripe papaya is not a
good source of protein because unripe papaya contains more protein. The vitamin C content of the hard ripe
and very ripe pawpaw was found to be fairly high. Papaya at different stages is a good source of vitamin A and
mineral elements (Ca, Mg, Na and K). Unripe pawpaw contains the highest amount of all the non-nutritive
elements (Saponin, Alkaloid, Tannin, Flavonoid and Phenol) analyzed which are beneficial to the body. In view
of these differences, though very ripe pawpaw is sweet and good for consumption, the unripe pawpaw is
recommended for use due to its nutritive value.

Thus, ascorbic acid, total phenolic content and antioxidant activities of Indian potato genotypes were studied. ‘Kufri Pukhraj’ was the best genotype in terms of nutritional components, since it contained the highest amount of ascorbic acid (19.42 mg/100g), and total phenolic content (68.20 mg GAE/100g). Also ‘Kufri Pukhraj’ had the highest DPPH radical scavenging activity of 67.30%. On the other hand, genotype ‘Kufri Chipsona-1’, most commonly used cultivar for processing, displayed the lowest content of total phenolics (31.30 mg GAE/100g) and total antioxidant activity (28.80%). Correlation analysis between total phenolic content and antioxidant activity (r=0.8502) showed a high degree of correlation indicating that these bioactive components contributes to the total antioxidant activity in potato genotypes.
RESIDUAL ESTIMATION OF ISOPROTURON, ATRAZINE AND GRAIN PROTECTANTS IN STORED ...ijabjournal
This study was carried out to see the occurrence and level of pesticide residues in stored wheat grain samples. Wheat grains were collected from different godowns located in Faisalabad district. Weedicide residues in wheat grains were analyzed by using thin plate liquid chromatography and validated high
performance liquid chromatography. On the basis of extent of inhibition of the Hill reaction, it was found that the level of atrazine was (0-0.028 ngkg-1) and the level of isopproturon was (0-0.024 ngkg-1) in test samples. The calculated values were below the Maximum Residue Limit (MEL) i.e. 100 ngkg-1 for atrazine and 2200 ngkg-1 for isoproturon. It was found that presence of herbicide residues in stored wheat was negligible. Further, on wheat grain samples placed in jars and treated with deltamethrin and cypermethrin @0.4 and 0.8% concentration. The persistency data was calculated after 1 hour, 7, 15 and 30 days of treatment. The grain protectants were continuously degraded with the passage of time and after the 30 days
the amount of residues of the grain protectants was found to be very small. It was concluded that the use of the grain protectants in the powder form in combination with other botanicals on stored wheat samples is feasible to reduce the insect pest in stored grains.
Phytochemical Screening and Gc-Ms Analysis of Garudan Samba Traditional Rice ...Agriculture Journal IJOEAR
Abstract— The Garudan Samba, an important Traditional variety of Tamil Nadu was investigated for its phytochemical screening and GCMS study. The brown rice was extracted using ethanol. The results obtained after GCMS studies were confirmed by spectral analysis. The analysis of the ethanol extract showed the presence of n-Hexadecanoic acid, 9,12-Octadecadienoic acid (Z,Z)-, and Oleic acid, as major constituents of the total compounds (76.33%), which have the capacity to prevent many health related disorders. It also contained the medicinally important compounds like Caryophyllene, Ethyl Oleate, Squalene, γ-Tocopherol, Lup-20(29)-en-3-ol, acetate, (3β)-, and phyto sterols like Campesterol, Stigmasterol and β-Sitosterol. Hence, Garudan samba may be considered as one of the important Traditional variety with high level of medicinally important phytoconstituents.

Evaluation of fungicides and biological agents for the management of mango an...Agriculture Journal IJOEAR
Abstract— Mango is an important fruit crop in area and production in Gujarat also, where it is cultivated over an area of about 130.1 thousand hectares with annual production of 911.3 thousand tones with productivity of 7.01 tones/ha. Its plantation has become quite popular in the districts of Valsad, Junagadh, Navsari, Kutch, Surat, Amreli and Bhavnagar because of favourable agro-climate condition. Mango is affected by number of diseases at all the stages of its development right from plant in nursery to the fruit in storage or transit. Mango is prone to many fungal diseases like Anthracnose, Rhizopus rot, Stem end rot, Penicillum rot, Black mould rot, Mucor rot, Phyllosticta rot, Pestalotiopsis rot, Macrophoma rot and powdery mildew, leading to heavy loss in yield. Among these diseases, anthracnose is the major disease of mango as it occurs at all the growing parts including leaves, twigs, flowers, fruits except root and trunk throughout the year. Anthracnose caused by Glomerella cingulata (Stoneman) Spauld and H Schrenk (anamorph: Colletotrichum gloeosporioides (Penz.)) appear to be more severe causing devastation of mango fruits during grading, packing, transportation, storage and marketing (Pathak, 1980).
The nutritional composition and fungal spoilage of Dacryodes edulis fruits were carried out in the Department of Forestry/ Environment Laboratory using standard procedures. The experiment was laid out in a Completely Randomized Design (CRD) with six treatments and three replicates. The fungal pathogens isolated from the rotted fruits were Aspergillus niger, Aspergillus flavus, Rhizopus stolonifer, Fusarium pallidoroseum, Botryodiplodia theobromae and Colletotrichum gloeosporioides. The predominant spoilage causing fungi were Colletotrichum gloeosporioides (60%) and Aspergillus niger (52%). Proximate analysis revealed that the affected fruits had significantly reduced (P<0.05) quality when compared to the uninfected fruits in terms of carbohydrate content, protein, oil content, moisture, crude fibre and Ash content. This work holds promise on the importance of the nutritional properties of the fruits in screening for rot tolerance and storage stability.

Genetic Variability for Antioxidant Activity and Total Phenolic Content in Fo...CrimsonpublishersNTNF
Total phenolic content and antioxidant activity were evaluated in 139 diverse genotypes of four pulse crops including 54 genotypes of chickpea (Cicer arietinum), 37 lentil (Lens culinaris), 21 pigeonpea (Cajanus cajan), and 26 blackgram (Vigna mungo). Results indicate significant genotypic variation (p < 0.01) for total phenolic content (TPC) as well as antioxidant activity (AOA). Amongst the four major pulse crops tested, maximum mean phenolic content was recorded in blackgram genotypes (7.01mg GAE/g), followed by lentil (3.46mg GAE/g), pigeonpea (3.32mg GAE/g) and chickpea (2.30mg GAE/g). In general, the Mediterranean landraces of lentil had higher phenolic content as compared to the other lentil varieties and breeding lines. Amongst the chickpea genotypes the phenolic content ranged from 0.40 to 5.63mg GAE/g and comparatively higher value for phenolic content was recorded in desi types (2.67mg GAE/g) as compared to the Kabuli types (1.05mg GAE/g). The antioxidant activity (AOA) was assayed in mature dry seeds utilizing DPPH (2,2-Diphenyl-1-picryl hydrazyl) radical scavenging assay which ranged from 1.73 to 19.14μmole Trolox/g tissue. As observed for TPC, highest AOA was also recorded in blackgram genotypes (19.14μmole Trolox/g tissue), followed by pigeonpea (2.72μmole Trolox/g tissue), chickpea (2.05μmole Trolox/g tissue) and lentil (1.73μmole Trolox/g tissue). Highly significant genotypic as well as phenotypic correlation (p<0.01) was recorded between phenolic content and antioxidant activity in chickpea, lentil as well as blackgram (rG values ranging from 0.268 to 0.850 and rP from 0.253 to 0.817), however, surprisingly the values were non-significant in case of pigeonpea. Strongest genotypic correlation was recorded in chickpea (rG=0.850), followed by lentil (rG =0.744), and blackgram (rG =0.268). High broad-sense heritability (h2bs) (0.89 to 0.97) for phenol content was recorded which indicates that substantial portion of total variation for phenolic content is due to genetic effects.

Effect of Fermentation on the Nutritional and Antinutritional Composition of ...IOSR Journals
The dehulled seeds of three varieties of Lagenaria siceraria were subjected to control fermentation process. The fermented and unfermented seeds were analysed for their nutritional and anti-nutritional compositions using AOAC 1998. The fermented seeds were found to contain high amount of crude protein (48.12%) and crude fibre (4.11%) compared to 27.42% and 0.67% for unfermented seeds respectively. Similarly, crude lipid content of the seeds decreased by about 75%. The process also results in decrease in phytate, oxalate, tannins and cyanide content with consequent increase in nitrate and Vitamin C. Hence fermenting the seeds is an important way of exposing its protein content and reducing the antinutritional content. The seeds were found to have good potentials for preparation of condiments which are commonly used in the preparation of soup.
Evaluation of Nutritional Components of Carica papaya L. At Different Stages ...IOSR Journals
The study compared the nutritive value of Carica papaya L. fruit at different ripening stages with the
aim of advising consumers and biological world when best to consume the fruit. Proximate, mineral and vitamin
analysis were carried out on the pulp, peel and seeds of fruits. Results showed that unripe papaya is a good
source of carbohydrates, vitamins and proteins, and the content decreases as it ripens. Very ripe papaya is not a
good source of protein because unripe papaya contains more protein. The vitamin C content of the hard ripe
and very ripe pawpaw was found to be fairly high. Papaya at different stages is a good source of vitamin A and
mineral elements (Ca, Mg, Na and K). Unripe pawpaw contains the highest amount of all the non-nutritive
elements (Saponin, Alkaloid, Tannin, Flavonoid and Phenol) analyzed which are beneficial to the body. In view
of these differences, though very ripe pawpaw is sweet and good for consumption, the unripe pawpaw is
recommended for use due to its nutritive value.
Nutritive compounds from leaves of Moringa oleifera L. and beans of Vigna ung...Agriculture Journal IJOEAR
Abstract - The nutritive compounds of the shoots of Borassus aethiopum M. consumed in Côte d'Ivoire is not yet revealed whereas popularization of this plant’s basis food recipes is planned. The current study investigates the nutritive parameters of new shoots of Borassus aethiopum M., leaves of Moringa oleifera L. and beans of Vigna unguiculata W. in order to improve their valorization. Initially, samples of Palmyra are processed into meal, while powders are produced from those of Moringa and Cowpea. Then, seven nutritive traits performed from these derived products allow comparison of the studied food resources. The work showed a great divergence (P<.01) between the samples relating to the whole parameters. Thus, the leaflets powder of Moringa is more provided in ash (4.19±.05 g/100 g), lipids (8.35±.01 g/100 g) and fibers (5.74±.01 g/100 g) than samples resulting from Cowpea and Palmyra. On the other hand, the powder of Cowpea beans highlights the greatest proteins content (27.24±.13 g/100 g); whereas the meal deriving from shoots of Palmyra represents the most significant source of carbohydrates, either fermented (84.10±.11 g/100 g) or unfermented (83.79±.10 g/100 g). The meal of Palmyra is also richer in soluble sugars (5.19±.01 to 5.23±.01 g/100 g), moister (9.90±.03% to 10.03±.04%) and has the most significant caloric energy value (315.03±.10 to 315.41±.10 kcal/100 g).
The new shoots tubers, leaves and beans of respective Palmyra, Cowpea and Moringa plants are with diverse nutritive composition. Their uses in composite food formulations could contribute in preservation of the biodiversity, to ensure food safety for populations and to address the poverty and wilderness concerns.
Nutritional and Phytochemical Properties of Wild Black Plum (Vitex doniana) S...AI Publications
The present study explores the potential usefulness of wild black plum (Vitex donia) seed from Ebonyi State; by assessment of nutritional and phytochemical attributes of the seed which is usually discarded as waste after consumption of the fruit pulp. Fat and protein were the major nutrients found in the seed, with values of 36.52% and 27.57% respectively. Fatty acid profile showed that monounsaturated oleic acid (58.54%) and saturated palmitic acid (34.24%) are the predominant fatty acids of the seed oil; while amino acid profile showed that thrionine (7.55%) and methionine (6.22%) constitute the major essential amino acids; and proline (8.64%) and glutamic acid (7.33%), the major non essential amino acids. Total essential amino acid content of 37.17% was recorded, indicating that the seed can be considered a good source of essential amino acids. Ash content was 5.18% and is an indication that the wild seed contains reasonable amounts of minerals. In terms of phytochemicals, appreciable amounts of alkaloids (11.40mg/100g) and flavonoids (3.75mg/100g) were recorded, in addition to high level of phenolic compounds (170mg/100g) which suggests that the seed could possess good antioxidant properties. The above findings are indications that great potential exists for wild black plum seed as good source of nutrients and phytochemicals.

Proximate and Phytochemical analyses of Raw and differently processed Pigeon pea seeds as potential Animal feed was conducted at the Nutritional Laboratory of Food Science and Technology, Rufus Giwa Polytechnic, Owo, Ondo State, Nigeria. Pigeon pea (Cajanus cajan) as the test ingredient was obtained from local markets in Owo. The seeds were handpicked and winnowed to remove all the foreign materials, after which the seeds were processed using the following methods; soaking, boiling, and toasting at different times (24 hours, 48 hours, and 72 hours soaked; 15 minutes, 30 minutes, and 45 minutes boiled; 5 minutes, 10 minutes, and 45 minutes toasted). Proximate and phytochemical analyses were carried out using standard methods of analysis. The results revealed that the anti-nutritional factors in the processed pigeon pea seed meal (PPSM) had a lower range for oxalate (0.81-2.07mg/g), phytic acid (0.46-9.02mg/g), saponin (0.85-2.97mg/g), tannin (0.21-1.35%), and trypsin inhibitor (1.01-13.11%) as against 2.43mg/g, 10.71mg/g, 24.72mg/g, 4.17%, and 29.40% obtained for raw pigeon pea seed meal, respectively. It was concluded that processing (soaking, boiling, and toasting) of PPSM reduced the level of anti-nutritional factors (oxalate, phytate, saponin, tannin, and trypsin inhibitor), and thus the inclusion of processed pigeon pea seed meal is recommended as an ingredient in animal feed as it offers high nutritive value due to its high crude protein content. Also, processing by soaking, boiling, or toasting as analyzed in this study is recommended to reduce the content of its anti-nutritional factors.
Fruit and Vegetable Waste Hydrolysates as Growth Medium for Higher Biomass an...Premier Publishers
Fruit and vegetable wastes include peels, pulp and seeds that constitute about 40% of the total mass and constitute huge environmental problems. Cultivation of microalgae that utilizes fruit and vegetable wastes as feedstock to produce value added products such as biomass and lipids is a unique approach. Different concentrations of fruit waste hydrolysate (FWH) and vegetable waste hydrolysate (VWH) were used for heterotropic cultivation of Chlorella vulgaris thereby optimizing the suitable hydrolysate concentration for higher biomass and lipid production. FWH in the ratio of 8:2 has produced maximum specific growth rate of 1.92 µ d-1. Higher biomass was recorded in growth medium supplemented with FWH (0.16 mg L-1) than VWH medium. Highest chlorophyll content of 7.2 mg L-1 was observed in 8:2 ratio of FWH whereas it was 4.3 mg L-1 in VWH at the same concentration. Carotenoid content was highest in VWH than FWH media with a maximum content of 0.52 and 0.42 mg L-1 respectively. Fruit waste hydrolysates significantly increased the total lipid content than the vegetable waste hydrolysate medium. Highest lipid content of 6.63 mg L-1 was recorded in 8:2 ratio of FWH. This work demonstrates the feasibility of fruit waste hydrolysate as a nutrient source for algal cultivation and a cost reduction of growth medium in algal biomass and lipid production.

The ruminant animal feed ingredients consisting of forage with the combination of grass and legume which were almost limited in availability, the cocoa leaves as agricultural wastes or wastes containing low nutrient plantation low used as alternative feed ingredients. To overcome these problems required a simple technology that is fermentation using microorganisms indigenus so that the effluent quality cocoa can be improved. Indigenus microorganisms were microbes that exist in individuals without disturbing the activities. The purpose of this research was to improve the quality of rumen fluid characteristics and digestibility of cocoa leaves fermented by microorganisms indigenus. The method used in this study was completely randomized design factorial with three replications, treatment factors consist of A as the level of microbes (A1 = 5%, A2 = 10%, A3 = 15%) and factor B as the duration of fermentation (B1 = 2 day, B2 = 4 days, B3 = 6 days) and the variables; the nutrient content and digestibility of cocoa leaves before and after being fermented and the characteristics of rumen fluid in vitro methods. The results showed that the increasing levels of use of microbes and fermentation time can enhance the quality of cocoa leaves that reduce the content of dry material from 31.389 to 25.488% and increase the protein content of the coarse 6.153 to 7.483%. Dry Material digestibility increased from 27.379 to 32.942% and 27.432% Protein 21,435- rough. Rumen fluid characteristics were rumen fluid pH ranges from 7.427 to 7.603, NH3 production ranges from 16.820 - 19,975mg / 100ml, and Volatyl Fatty Acid production from 83.667 to 101.000 mM. The conclusion that increasing the digestibility quality cocoa fruit leather could be made by fermentation by microorganisms indigenus.
Site Effects on Energy, Phytonutrients and Anti-Nutrient Contents of Ruminant...Premier Publishers
Feed constitutes about 80% of the total livestock production cost in Nigeria. The problem is more critical during the dry season more especially for ruminants. This study was conducted to determine the effect of location on chemical composition of sugarcane peels as animal feed in Kano State, Nigeria. The three sugarcane peel samples used for the study were from three different locations namely; Kano, Kaduna and mixed sugarcane peel (Kano and Kaduna). Known weights of the peels were sun dried and determined in the laboratory for proximate, energy, pH and phytonutrients. Results showed that ether extract, nitrogen-free extract, and dry matter were influenced by the location. Energy values (3891. 34 – 4037.53kcal/kg) were also affected (P< 0.05) by location of the sugarcane peels meal. Crude protein (6.02 – 8.20%), crude fiber (29.99 – 30.22%) and ash were not significantly affected (P > 0.05) by location. The cellulose, hemicelluloses, NDF, ADF, and ADL of sugarcane peels meal were all significantly (P <0.05) affected by the location. The pH values (6.38 – 6.67) were significantly affected (P < 0.05) by location. The phytonutrients of all the components were not significantly affected (P > 0.05) by the location. Based on these findings, sugarcane peels meal from all the locations can serve as an alternative feed ingredient for ruminants, since the peels contained substantial amount of energy and protein. However, the peels meal can also be safe for ruminants’ feedings because it contained small amounts of anti-nutritional factors.
Development of Sorghum Noodles Fortification with Moringa Moringa Oleifera Le...ijtsrd
The study of noodles from sorghum flour, rice flour, and, Moringa oleifera leaf powder development was carried out at the Department of Food Technology, Parul Institute of Applied Sciences, Parul University, Vadodara Gujarat, India. The cereal grain sorghum has a number of agronomic benefits, contains substances that are good for your health, and is gluten free. One of the most beneficial tropical trees is Moringa Oleifera, which offers vital nutrients and antioxidants to treat vitamin and mineral deficiencies, support a healthy cardiovascular system, help to promote normal blood sugar levels, neutralize free radicals, improve eyesight, mental clarity, and bone strength, and may be helpful in cases of malnutrition, general weakness, lactating mothers, menopause, depression, and osteoporosis. Moringa is a multi beneficial plant with high nutritional value, making it an excellent protein supplement for malnutrition and animal feed. Although Moringa oleifera leaves are high in nutrients, the addition of saponins may increase the bitter taste and unpleasant smell. This study set out to create noodles using moringa leaf powder, sorghum flour, and rice flour and to assess their sensory acceptance, antinutritional content and proximate composition. The findings revealed in moisture 7.62 , total ash 5.48 , protein 6.80 , fat 1.86 , carbohydrate 78.24 , energy 358.9 , calcium 242.4 Ca , and potassium 353.5 content, the total number of E. coli 0157, and coli form. In order to guarantee global food security and meet nutritional needs, the concentration of moringa plant powder must be limited. Moringa Oleifera leaves powder affected, macronutrient, and minerals content in wet noodle products. It is recommended that concentrations of 5 , 10 , and 15 should not exceed 5 because it affects the organoleptic of the product.

Two wastes from animal origin, viz., human hairs and egg shells were evaluated for different manifestations of white oyster mushroom, Pleurotus florida. The mushroom utilized both the
substrates for their growth and sporophore formation. The mycelial growth was significantly (P=0.05) faster on egg shell (18 days) as compared to human hair (23 days). The crop of mushroom was harvested in four flushes where human hairs showed higher yield and biological efficiency of mushroom (165 gm, 33%) than egg shells (155 gm, 31%), respectively. In respect of yield parameters such as yield, biological efficiency, number of mushroom fruit bodies and average weight of
sporophores, both the substrates were statistically at par to each other. Utilization of human hairs egg shells by P. florida reveals a new strategy for mycoremediation of these wastes.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.

Abstract: The need for detoxification of less utilized crops with similar nutritional composition with soybeans
as potential substitute or supplement for soybeans in conventional feeds production is obvious as price of
soybean continue to rise. Jatropha curcas is one of such crops which can serve as a potential source of dietary
energy and protein. However, the presence of anti-nutritional factors restricts the utilization of the Jatropha
curcas seed in animal feed. Several researchers however have shown that this obstacle can be overcome by
detoxifying the seeds, but many of them failed to established the effects of these detoxification methods on the
nutritional content of Jatropha curcas .The main objective of this study therefore was to determine the effect of
three simple inexpensive physical methods of detoxification (soaking, roasting and fermentation) on the
proximate and toxicological compositions of Jatropha curcas seed meal. To achieve this, Jatropha curcas seeds
sample used were divided into four parts. The first three parts were subjected to the three different physical
treatments after which they were dried to constant weight and while the fourth part was dried to constant weight
and milled. These four samples were then analysed for their proximate and toxicological composition .The
results showed that fermentation deactivated the antinutrients most in the seeds and did not adversely affect the
nutritional composition of the seeds.
Keywords: Anti-nutrients, Detoxified, Jatropha carcus, Fermentation, Roasting, Soaking.
I. Introduction
Increase in the prices of conventional livestock feeds has resulted in increase in the price of livestock
and livestock products, this makes it necessary to look for alternatives to the conventional feedstuffs that is
locally available and affordable in order to widen sources of raw material and prevents a transition to the use of
artificial feedstuffs and its dangerous effects on both the livestock and the consumers[1].As a result of this,
many less utilized crops are being examined for their potential to serve as a substitute or supplement to the raw
materials that are used for conventional feeds especially soybeans[2].
Jatropha curcas, a drought resistant shrub in the Euphorbiaceae family has been proposed as one of the
alternative [3]. The plant is well adapted to climatic zones with low rainfall or drought affected areas and even
survives in dry, stony and very shallow soil [4-6]. It is resistant to diseases and can grow on wasteland where no
irrigation facility is available [7]. Jatropha curcas seeds are rich in oil, protein, energy and low in fibre with
significant quantities of macrominerals like sodium, potassium, magnesium, calcium, phosphorus and
microminerals like manganess, iron and zinc[8,9].The kernel of Jatropha curcas seed contains 57 – 63% oil[10]
and arou33.6 – 34.5% crude protein[8,11].The protein quality of the J. curcas seed cake is high and the quantity
of essential amino acids (except lysine) are higher in Jatropha seed cake than in the FAO reference protein for a
growing child[12].
According to Aderibigbe et al.[13] Jatropha meal or the seed cake (fully defatted Jatropha seed) contain
almost the same amount of protein as raw Jatropha seeds of which 90% exist as true protein. The nutritional
value of Jatropha meal compares favourably with those from conventional seed meals, such as soybean, making
it a potential source of dietary energy and protein [14-16]. However, the presence of anti-nutritional factors such
as phorbol esters, saponins, tannins, phytate, lectins, hydrocyanide, oxalate restricts the utilization of the
Jatropha curcas meal in animal feed [17, 18].
This obstacle however can be overcome by detoxifying the seed through solvent extraction of the
kernels which is the most exploited but expensive methods of detoxification [19]. Other researchers have
therefore propose other simple inexpensive physical methods like soaking, roasting, germination, autoclaving
,cooking and fermentation for its detoxification[8,20]. The main objective of this study is to determine the effect
of three of these physical methods (soaking, roasting and fermentation) on the proximate and toxicological
compositions of Jatropha curcas seed meal.

II. Materials And Methods
2.1Collection and Preparation of the Jatropha Curcas Seeds
Mature seeds of Jatropha curcas were obtained from Agwada area of Nasarawa state Nigeria. The
sample was cleaned manually to remove all foreign materials and immature seeds. The sample was thereafter
divided into four parts and processed as shown below:
Raw: Jatropha curcas seeds in this group were dried in the oven at 40o
C to constant weight after which the seeds
were removed from their shells and milled.
Roasted: Jatropha curcas seeds in this group were placed in a pan containing dry sand and roasted for
30minutes at 160o
C with continuous stirring after which they were allowed to cooled, de- shelled and
milled[20].
Soaked: Jatropha curcas seeds in this group were soaked in a basin of tap water at ratio of 1:10 (w/v) at room
temperature for 5days after which they were dried in an oven at 40o
C to constant weight, de- shelled and milled
[20].
Fermented: Jatropha curcas seeds in this group were lined on a tray that had already been cushioned with wet
cotton wool and further covered with wet cotton wool. They were then allowed to ferment for 5 days with
consistent watering after which they were dried in an oven at 40o
C to constant weight, removed from their shells
and milled. After all the samples have being milled they were passed through a 0.5 mm sieve and stored in air
tight containers until they were required for further analysis.
2.2 Proximate Analysis
All the milled samples were analysed for their proximate composition according to the methods of A.O.A.C[21].
2.3 Antinutritional Contents Analysis
The AOAC [21] Analytical Method was used to determine the oxalate content of the samples. Phytate
was determined using the method descibed by Mohamed et al.[22].The cyanide in the samples were determined
by the method used for flour samples by Ojo et al.[23] and tannis as described by Aderibigbe et al[13].

The results are expressed as + standard deviation of four observations.
a= significant decrease at p<0.05 compare with raw sample. b = significant increase at p<0.05 compare with raw
sample.
Table 1 shows the percentage crude protein in the four samples. It was observed that roasted Jatropha
curcas has the highest amount of crude protein (29.04%) while the raw unprocessed Jatropha curcas has the
lowest value of crude protein (27.76%). The increase in protein contents of roasted sample might be attributed to
an increase in the free nitrogen content after roasting [24]. The fermented sample had the lowest crude protein
value (26.50%) which might be as a result of degradation of the protein by micro organisms. This was also
observed in fermented B. Eurycoma “Achi” where a decrease in protein content was recorded during
fermentation [25]. The slight decrease of protein in soaked sample (28.07%) when compared to roasted sample
may be as a result of leaching out of some nutrients in water which agree with the work of Obasi and Wogu[26]
who recorded decrease in protein content of soaked yellow maize.
From the result, it is evident that the raw Jatropha curcas has the highest crude fat (45.91%) closely
followed by roasted sample (42.47%). Soaked and fermented samples have the lowest crude fat composition
(35.25% and 33.91% respectively). This may be as a result of utilization of lipids by fermentation microbes to
obtain energy for their activity when sugars were in short supply. This result is comparable to that obtained
durng the fermentation of locust bean [27]. For the crude fibre, roasted sample has the highest percentage of
crude fibre (7.06%) with the lowest value recorded for the fermented sample (3.61%) which is similar to results
of Makinde et al. [28] on fermented sesame seeds.

Table1 also shows the result for percentage moisture content in all the four samples. The raw
unprocessed Jatropha curcas meal had moisture content of (7.08%). The soaked sample had the highest value for
moisture content (10.00%) which is as a result of soaking in water. The fermented sample had the second
highest value for moisture content which is as a result of the fermentation process which involved soaking in
water. The roasted sample had the lowest value for moisture (4.02%) which is obviously due to drying effect of
roasting. The raw unprocessed Jatropha curcas has the highest percentage of ash content (5.00%). The slight
reduction in the ash content of fermented and soaked samples (4.02% and 4.03% respectively) might be as a
result of diffusion of minerals into the water[29,30]. The reduction of ash content in roasted sample (4.08%)
might be as a result of loss of organic residue due to heat when it was roasted.

The results are expressed as + standard deviation of four observations.
a= significant decrease at p<0.05 compare with raw sample. b = significant increase at p<0.05 compare with raw
sample.
The effect of different processing methods on the Antinutritional contents of processed Jatropha curcas
is shown in Table 2. The raw Jatropha curcas has the highest as expected followed by the roasted sample which
asserts the finding of previous researchers that phytate is the major heat-resistant antinutritive component in
Jatropha curcas. These results coincide with those obtained by Makkar et al. [15].The phytate content also
decreased with soaking (6.42%). This reduction may be attributed to leaching out of phytate ions into soaking
water which is due to change in permeability of seed coat[8,31,32]. The significant reduction in phytate content
observed in the fermented sample (3.89%) might be due to the activity of enzymes such as phytase and oxidase
produced by fermenting microbes[33] and leaching out of phytate . The antinutritional activity of phytate lies in
its ability to form complexes with metals like Cacium, Zinc, Magnessium and Iron[28]. Phytates have also been
implicated in decreasing protein digestibility by forming complexes and also by interacting with enzymes such
as trypsin and pepsin[8] .Therefore the high level of phytate in the unprocessed seeds might decrease bio-
availability of minerals especially calcium and iron, impaired protein digestibility through the formation of
phytic-protein complexes [34].
The raw Jatropha curcas had cyanide content of (12.8mg/kg), in contrast to the significant decrease in
cyanide content observed in soaked sample (4.90mg/kg) and fermented sample (4.63mg/kg). This reduction may
have occurred due to leaching out of cyanide when it was soaked in water as it forms Hydrocyanic acid in water
which is a very volatile compound from which free cyanide is released by the enzyme limarase from the cells to
dissolve in water[35] and due to microbial activity during fermentation.
The raw Jatropha curcas had a tannin value of (0.22mg/100g). The reduction observed in soaked
sample of Jatropha curcas (0.20mg/100g) and fermented sample of Jatropha curcas (0.12mg/100g) might as a
result of leaching of tannins into water[36].
Fermentation had a significant effect on oxalate contents compare to raw Jatropha curcas (Table 2).
This reduction in oxalate as a result of fermentation may be as a result of activity of enzymes such as oxidase
produced by fermenting microbes[33]. The not too significant reduction of oxalate in soaked sample may be as a
result of reabsorption of leached out oxalate ion back into the seeds. Roasting also caused a significant
reduction in oxalate content (13.72mg/100g) as Oxalates are heat liable and can be partially or completely
denatured when exposed to elevated temperature[28] .
IV. Conclusion
In conclusion, different physical treatments (fermentation, roasting and soaking) examined reduced the
antinutritional contents of Jatropha curcas meal and did not adversely affect its high nutritional content but
Fermentation was the most effective method of reducing the antinutrients examined and also did not adversely
affect the nutritional contents. However before the utilisation of Jatropha curcas as feed further research should
be carried out to determine the effect of the methods examined on phorbol esters other possible antinutritional
factors that were not examined in this study.
