Pineapple is an important fruit crop in India, where it is cultivated on over 106,000 hectares. The top producer of pineapple worldwide is Thailand, followed by Brazil and Costa Rica. In India, the major pineapple producing states are Assam, Tripura, West Bengal, Kerala, and Karnataka. Proper post-harvest handling is important to minimize losses during harvesting, grading, transport, and storage. This involves cleaning, trimming, waxing, sorting, packing, and storing pineapples at temperatures between 10-12°C. The main post-harvest disease is black rot caused by the fungus Thielaviopsis paradoxa, which leads to a soft rot starting from the stem end.
Pineapple is an important fruit crops of India and cheaply available in the market. It is one of the widely
grown and consumed fruit in all parts of the world due to presence of distinct flavour and taste. It is rich in
carbohydrate, potassium, calcium, phytonutrients, vitamin C and bromelain. In terms of pineapple
production India’s has 6th in the world and leading pineapple growing states are West Bengal, Assam,
Tripura, Karnataka, Bihar, Manipur, Meghalaya and Nagaland. It has been observed that at post
production level a significant proportion (15-25 %) of the produce get spoiled due to improper post
harvest handling practices, which causes huge economic loss to the growers. The availability and
accessibility of food can be increased through improved production technology, distribution cool chain,
preservation and by reducing the losses. Thus, reduction of post harvest food losses is a most critical
component of ensuring future global food security. Post harvest loss of pineapple can be minimize by
adopting various suitable post harvest handling practices that are presently in practice all over the world to
extend its shelf life. Post harvest handling practices viz., post harvest management, processing and value
addition and waste utilization for pineapple are discussed in brief.

Harvesting methods and Postharvest handling of Fruits and.pptxPreranaBhoi
In agriculture, maturity indices are parameters used to assess the developmental stage and readiness of crops for harvest. These indices can include factors like color, size, firmness, and sugar content for fruits, or seed color and moisture content for grains. Monitoring these indices helps farmers determine the optimal time to harvest for maximum quality and yield.Maturity indices for fruits vary depending on the type of fruit, but common indicators include:
1. **Color:** Look for changes in the fruit's color, which often indicates ripeness. For example, green apples turning red.
2. **Firmness:** Assess the fruit's firmness; it should be neither too hard nor too soft. This varies among different fruits.
3. **Size and Shape:** Consider the typical size and shape of the mature fruit. Deviations may indicate ripeness.
4. **Aroma:** Some fruits emit a characteristic aroma when fully ripe. Smelling the fruit can be a good indicator.
5. **Sound:** For fruits like melons, a dull, hollow sound when tapped can suggest ripeness.
6. **Taste:** The sweetness or flavor profile can change as fruits ripen, so tasting a sample can help determine maturity.
Monitoring these indices collectively assists in harvesting fruits at their peak quality and flavor.
Post-harvest management is crucial to preserve the quality and extend the shelf life of agricultural produce. Key practices include:
1. **Sorting and Grading:** Separate produce based on size, quality, and ripeness to ensure uniformity and facilitate handling.
2. **Cleaning:** Remove dirt and debris to prevent the growth of microorganisms and maintain product freshness.
3. **Packaging:** Use appropriate packaging materials to protect against physical damage, dehydration, and contamination. Different fruits and vegetables may require specific packaging.
4. **Temperature Control:** Maintain optimal storage temperatures to slow down ripening and reduce decay. Cold storage or refrigeration is common for many fruits and vegetables.
5. **Humidity Control:** Adjust humidity levels in storage facilities to prevent wilting or excessive moisture, depending on the produce.
6. **Ventilation:** Ensure proper air circulation to control temperature and humidity and prevent the buildup of ethylene gas.
7. **Ethylene Control:** Manage ethylene, a natural plant hormone, as it can accelerate ripening. Some fruits are sensitive to ethylene and should be stored separately.
8. **Quality Monitoring:** Regularly inspect produce for signs of decay, and remove damaged items to prevent the spread of spoilage.
9. **Transportation:** Handle produce carefully during transportation to minimize bruising and damage. Use suitable transportation methods, such as refrigerated trucks for perishable items.
10. **Market Timing:** Time the entry of produce into the market to align with demand and maximize profitability.
Effective post-harvest management practices contribute to reducing losses, maintaining quality, and ensuring that

Mango has been grown in India since long and is considered to be king of fruits. Its mention has been made in Sanskrit literature as Amra.
Alexander the great found a mango garden in Indus valley in 327 B.C. Ameer Khurso saint and poet from Turkoman wrote a poem on mango as early as 1330 A.D. Akbar the great (1556-1605) planted one lac mango trees in his bagh, which was named as Lakh Bagh.
Origin:
Vavilov suggested ‘Indo-Burma’ region as the centre of origin of mango. Folklore and religious sites of Indian people are attached to mango. Mango has attained the status of the national fruit of India. It travelled to west; South Africa and Mexico through mango stones. Genus Mangifera contains 49 species of which only 41 are valid. Mangifera indica to which the most of the present Indian cultivars belong is of great importance. Over one thousand varieties have been reported belonging to this genus. Some other genus found growing in India are M. sylvatica; M. caloneura, M. foetida and M. caesia. At present mango is commercially grown in Asia and European countries.
Area and Production:
Mango is commercially cultivated in Andhra Pradesh, West Bengal, Karnataka, Kerala, Bihar, Uttar Pradesh, Uttara Khand, Punjab and Haryana, Maharashtra and Gujarat. Mango cultivated over an area of 2309 thousand hectares with an annual production of 12750 thousand metric tones. India produces quality mangoes; Alphonso is highly liked by the western countries.
In Punjab, mango is being cultivated in whole of the sub-moutane belt comprising Gurdaspur, Hoshiarpur Roop Nagar, Fatehgarh Sahib, Mohali and Patiala districts. Now its cultivation has spread to arid canal irrigated areas of northern India.
Uses:
Mango leaves are fed to cattle in the shortage of fodder. Leaves are also used in various ceremonies in Hindu rituals. Mango tree has certain medicinal properties. Its wood is used for furniture making and as fuel. Fruit is a source of vitamin A and C. Mango pulp is laxative in nature and has unique nutritional value.
Fruit is utilized at all stages of development in various ways ranging from chutney, pickles and curries. Ripe fruit is taken after meals. Various types of syrups, nector, jams and jelleys are prepared from the pulp/juice. The stones kernels are fed to pigs. The bark of the wood is useful in the industry.
Botany:
Mango belongs to family Anacardiaceae. Fruit plants such as cashew nut (Anacardium occidentale) and pistachio nut (Pistacia vera) also belong to this family. Three species of genus Mangifera found in India are Mangifera indica with edible fruits, M. sylvatica with non-edible fruits and M. caloneura.
Mangifira indica (2n = 40). Seedling trees are big is size and can grow over 20 metre high with a same spread. Grafted trees can attain a height of 8-10 metres with a dome shaped top. Mango is evergreen with spreading branches. On road sides seedling trees have erect branches.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

14. Harvesting
• Fruit should be harvested when firm and mature.
• Fruit must be picked at optimum maturity & ripeness stage
to suit the market.
• Domestically marketed fruits should be harvested at the one-
half (1/2) yellow external surface color.
• For the export market fruit should be picked slightly sooner,
at mature or quarter-yellow (1/4th ) color stage.
• Fruits picked mature but prior to full ripeness (i.e. less than
1/4th yellow) will be firmer and better able to tolerate long
distance transport.
16. Determination of maturity index
1. Visual means
2. Physical --- ease of separation, specific gravity etc.
3. Chemical means --- TSS, acid, TSS : Acid ratio, Starch
content
4. Computation --- Chronological (eg. Days from bloom)
5. Physiological methods --- Rate of respiration, ethylene
production etc.
6. Optical --- Spectrophotometric techniques
7. Others --- Electromagentic, near-infrared reflectance etc.
17. Maturity Indices
• External and internal fruit characteristics can be used as indices to
determine harvest maturity
• External indices includes:
o Fruit surface color (in most cultivars),
o Extent of fruitlet (eye) flatness and
o Fruit size.
• Internal indices:
o TSS (i.e. sugar content) and
o Appearance.
• Best eating quality when fruit surface color is at the one-quarter to
one-half yellow stage.
• It is a compound fruit comprised of numerous individual fruitlets.
• Fruitlets mature progressively from the bottom part of the fruit to the
top.
• Fruit should have a minimum of 12% soluble solids near the base and
10% near the top.
18. Harvesting technique
• Pineapples are harvested by hand, with the pickers being
instructed as to the stage of maturity required.
• Fruit should be broken off the stalk with a downward motion, or
cut with a knife slightly below the base of the fruit.
• A large canvas picking sack or bamboo basket is strapped over
the shoulders is commonly used as a harvesting-aid.
• Up to 6 fruits can be put in sack/basket.
• Fruit may also be harvested in wooden or plastic field crates
19. A slightly translucent internal fruit is
indicative of maturity.

23. Steps of pineapple fruit for Marketing
• Initial step in preparation for market involves cleaning of the
outside of the fruit.
• Commonly used sanitizer is chlorine as sodium hypochlorite
(NaClO) to minimize cross-contamination.
• Washing whole pineapple (200 mg/liter) for 5 min.
• For the domestic market
o Trimming of stem at the base of fruit to a length of 1-2 cm.
o Removing any damaged or unsightly leaves in the crown.
o Gentle dry brushing of the fruit surface to remove dirt and dust.
• Similar protocol should be followed for the export market,
with more emphasis placed on fruit uniformity and quality.

25. Waxing
• For maximum potential shelf life, fruit should be waxed after
cleaning and drying.
• Food-grade waxes are appropriate for pineapples and can be
applied by dipping or spraying.
• Commonly used waxes for pineapples are mixtures of carnauba
and paraffin or polyethylene and paraffin.
• The type of wax chosen must be approved by the importing
country, if the market destination is for export.
• Wax should be applied only to the fruit surface and not the
crown, as many waxes cause injury to the crown.
• Beneficial effects of waxing include:
oReduction in fruit internal browning
o Less moisture loss
oShinier external appearance.

• Fruit should be sorted according to size, shape, firmness,
external color, insect damage, and decay.
• Visibly damaged fruit should be rejected.
• Different markets have different quality requirements
and the fruit should be graded to conform to the
individual market standards.
28. Ideal fruit characteristics
• Be clean and free of dirt or stains
• Be mature and firm
• Be well shaped and have fully developed eyes (fruitlets)
• Be free of punctures, wounds, and cuts
• Be free of sunburn, insect damage and decay
• Have a single crown

• Preferred method of packing is to place the fruit vertically on
the base, and then to place dividers between the fruits to
prevent rubbing and movement.
• With some cartons, this is not possible and fruit are laid
horizontally in alternating directions; where two layers of fruit
are packed, a divider is required between the layers.
• Another commonly used export carton for pineapples is a
single-layer corrugated fiberboard carton.
38. Storage
Source: APEDA
For maximum postharvest life, pineapple fruit should be cooled to 7-10 °C as
soon as possible after harvest and maintained at this temperature during
transport to market.
At this temperature, pineapples harvested at the quarter-yellow stage have a
shelf life of approximately 3-5 weeks.
Pineapple fruits are subject to low temperature breakdown known as chilling
injury, and should not be stored below 7°C.
39. Transportation
• Fruit should be transported carefully to market in order to
minimize bruise damage and subsequent postharvest decay.
• Use of strong protective packaging will help to minimize bruise
damage.
• Proper loading and stacking of the cartons in the bed of the
transport vehicle is essential to protect the product.
• Sufficient air circulation through the sides of the cartons is
necessary to avoid product re-warming during transport.
• Cartons should be covered and never exposed to direct sunlight
during transport.
• In the absence of refrigeration, the fruit should be transported
during the cooler part of the day.
40. Common Postharvest Diseases
• Pineapples are susceptible to a number of postharvest
diseases.
• Decay is significantly higher in mechanically injured fruit,
when poor sanitation practices are followed, or if postharvest
cooling is not provided.
• The fused nature of the fruitlets means that the flesh of the
fruit is not sterile and contains yeasts and bacteria.
• The most common ones are black rot, fruitlet core rot, and
yeasty fermentation.
41. Black Rot
• Caused by fungus Thielaviopsis paradoxa, most common
postharvest disease.
• It is also referred to as stem end rot, water blister, or soft rot and is
characterized by a soft watery rot of the flesh.
• Severity of this disease depends on the amount of fruit bruising or
wounding incurred during harvest and packing, the level of
inoculums on the fruit, and the postharvest temperature.
• Black rot does not occur in the field unless the fruit is overripe or
injured.
• Starts at the point of detachment of the fruit (stem end), although it
can readily infect bruised or other damaged areas of the fruit.
• Infection occurs 8 to 12 hours after wounding and symptoms begin
as a soft, watery rot which later darkens due to growth of the dark-
colored fungal mycelium and spores.
• Fungal growth is rapid at temperatures between 21-32°C.
42. Protection measure
• Appropriate postharvest sanitation (150 ppm
chlorine wash plus fungicide).
• The most effective postharvest fungicides for
controlling black rot are thiabenbazole, benomyl,
and captan.
• For effective control, the fruit must be dipped in
the fungicide within 6 hours after harvest.
• Storage of the fruit at 7°C is also necessary to
inhibit growth of the fungus.
43. Fruitlet Core Rot
• It is a postharvest fungal disease-yeast-mite complex of
pineapples caused by the fungi Penicillium funiculosum,
Fusarium moniliforme var. subglutinas, the round yeast Candida
guilliermondi, the fruit mite Steneotarsonemus, and the red mite
Dolichotetranychus floridanus.
• This disease complex is also called black spot or fruitlet brown
rot.
• Symptoms appear as brown to black colored areas in the center
part of individual fruitlets.
• This disease is more serious in low-acid cultivars.
• The principal means of reducing the incidence of fruitlet core
rot is by spraying the crop with an acaracide to control the
mites which spread the disease.
44. Yeasty Fermentation
• Pineapple fruits are not sterile inside and contain many non-
growing, but viable yeasts and bacteria.
• In damaged, overripe, and inter-fruitlet cracked fruit, existing
yeasts may start to grow or new yeasts may invade.
• The yeast Saccharomyces is most often responsible for
fermentation.
• Symptoms include fermentation, with bubbles of gas and
juice escaping through cracks in the skin.
• The skin eventually turns brown and leathery and the internal
flesh becomes spongy with a bright yellow flesh.
47. Postharvest Insects
• Mealy bugs are typically the worst postharvest insect
problems of pineapples.
• They invade the fruit prior to harvest and hide in crevices
between fruitlets, underneath the crown leaves, or inside
the whorl of the crown.
• Can be significantly reduced in population by pre-harvest
insecticide sprays and ant control.
• After harvest, need to be removed by brushing the fruit.
48. Sunburn
• Sunburn is common during hotter periods (> 35°C) ,
when the fruit is not shaded by leaves, and especially in
ratoon crops.
• Fruit flesh temperatures on the exposed side of the fruit
in the field can be 15°C higher than the air temperature
of about 27°C, and the crown leaves provide little
protection.
• The condition is more prevalent in the outer rows of a
field and when there is reclining fruit
Postharvest Disorders
49. Sunburn
• Localized sunburn of the fruit surface can be a problem
on fruit left exposed to full sun after harvest.
• The affected areas of the fruit surface show a bleached
yellow-white skin, with damage to the underlying flesh.
• The damaged tissue is more susceptible to postharvest
decay.
• Sunburn can be avoided by putting the fruit in a shaded
area after harvest.
50. Chilling Injury
• Chilling injury (CI) occurs in pineapple fruit stored below 7°C.
• External symptoms of CI include wilting and discoloration of the
crown leaves, failure of green-shelled fruit to yellow, browning and
dulling of yellow fruit, surface pitting of the fruitlets which
eventually coalesce into larger sunken lesions, and postharvest
decay.
• Internal symptoms of CI include flesh browning or darkening,
tissue softening, and off-flavor development.
• CI becomes more severe with decreasing storage temperatures
and increasing lengths of exposure to chilling temperatures.
• Immature fruits are more susceptible to CI than mature fruit. (Full-
green color stage pineapple may suffer CI at 10°C).
51. Internal Browning
• Internal browning is a common postharvest physiological disorder
affecting pineapples.
• More pronounced in those cultivars which have a low ascorbic acid
content.
• Severe in those fruits exposed to cool night temperatures followed by high
day temperatures prior to harvest.
• Storage of the fruit below 7°C also accentuates internal browning.
• Symptoms begin as small grayish translucent areas at the base of the fruit
near the core.
• These areas eventually darken and in severe cases the entire internal flesh
turns brown to black in color.
• Control of internal darkening may be obtained by waxing the fruit.
52. FleshTranslucency
• It is a physiological disorder in which the internal flesh becomes
shiny and translucent in appearance.
• It is more common in less mature harvested fruit.
• Translucency begins before harvest and continues during
storage.
• It is generally more common in fruits with small crowns.
• Waxing can reduce the rate of translucency development after
harvest.
• Translucent fruits are more susceptible to mechanical injury,
which leads to intracellular sap leakage and loss of marketable
fruit.
