Marketing Research Pizza Hut & Dominos
Marketing research is the systematic gathering, recording, and analysis of qualitative and quantitative data about products for high growth
McDonald's is one of the largest fast food chains in the world, serving over 68 million customers daily in 120 countries. It offers a variety of food and beverage products for eat-in and take-out, such as hamburgers, chicken, salads, snacks, and beverages. McDonald's uses several elements of the marketing mix to support its growth strategies, including over 36,000 restaurant locations globally, product delivery through kiosks, websites and apps, advertising, sales promotions and public relations. It also employs psychological pricing strategies such as price bundling and appearing more affordable. Key competitors include Yum Brands (Taco Bell, KFC, Pizza Hut) and Burger King.
KFC (the name was originally an initialism for Kentucky Fried Chicken) is a fast food restaurant chain that specializes in fried chicken and is headquartered in Louisville, Kentucky, United States (US). It is the world's second largest restaurant chain overall (as measured by sales) after McDonald's, with over 18,000 outlets in 120 countries and territories as of December 2012. The company is a subsidiary of Yum! Brands, a restaurant company that also owns the Pizza Hut and Taco Bell restaurant chains.
KFC was founded by Harland Sanders, an entrepreneur who began selling fried chicken from his roadside restaurant in Corbin, Kentucky, during the Great Depression. Sanders identified the potential of the restaurant franchising concept, and the first "Kentucky Fried Chicken" franchise opened in Utah in 1952. KFC popularized chicken in the fast food industry, diversifying the market by challenging the established dominance of the hamburger. By branding himself as "Colonel Sanders," Harland became a prominent figure of American cultural history, and his image remains widely used in KFC advertising. However, the company's rapid expansion saw it overwhelm the ageing Sanders, and in 1964 he sold the company to a group of investors led by John Y. Brown, Jr. and Jack C. Massey.
KFC was one of the first fast food chains to expand internationally, opening outlets in England, Mexico and Jamaica by the mid-1960s. Throughout the 1970s and 1980s, KFC experienced mixed fortunes domestically, as it went through a series of changes in corporate ownership with little or no experience in the restaurant business. In the early 1970s, KFC was sold to the spirits distributor Heublein, who were taken over by the R.J. Reynolds food and tobacco conglomerate, who sold the chain to PepsiCo. The chain continued to expand overseas however, and in 1987 KFC became the first Western restaurant chain to open in China. The chain has since expanded rapidly in China, which is now the company's most profitable market. PepsiCo spun off its restaurants division as Tricon Global Restaurants, which later changed its name to Yum! Brands.
KFC's original product is pressure fried chicken pieces, seasoned with Sanders' recipe of 11 herbs and spices. The constituents of the recipe represent a notable trade secret. Larger portions of fried chicken are served in a cardboard "bucket," which has become an icon of the chain since it was first introduced by franchisee Pete Harman in 1957. Since the early 1990s, KFC has expanded its menu to offer other chicken products such as chicken fillet burgers and wraps, as well as salads and side dishes such as French fries and coleslaw, desserts and soft drinks, the latter often supplied by PepsiCo. KFC is known for the slogan "finger lickin' good," which has since been replaced by "Nobody does chicken like KFC" and "So good."
Dunkin' Donuts is expanding globally and has signed an agreement with Jubilant FoodWorks Ltd to enter the Indian market. Dunkin' Donuts will develop and operate over 500 restaurants in India over the next 15 years, with the first locations opening in early 2012. This represents the largest international development commitment in Dunkin' Donuts' history. Dunkin' Donuts coffee and baked goods are well-known internationally but will face competition in India from local cafes and sweet shops as well as chains like Cafe Coffee Day. The company plans to adapt its menu to Indian tastes by including local flavors while maintaining a Western atmosphere.

The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout tropics and subtopics. Coconuts are different from any other fruits because they contain a large quantity of “water” and when immature they are known as tender- nuts or jelly- nuts and may be harvested for drinking. When mature, they still contain some water and can be used as seed nuts or processed to give oil from kernel, charcoal from the hard shell and coir from the fibrous husk.

The document discusses cocoa processing and value addition. It begins with an introduction to cocoa and provides information on cocoa production in India. It then covers cocoa harvesting and post-harvest handling, focusing on fermentation. Fermentation is an essential process that develops flavor, reduces bitterness, and allows biochemical changes in the cocoa beans. Different fermentation methods like heap, box, basket and tray methods are described. The key steps and factors affecting fermentation are also summarized.
Fermented fruits and vegetables have been produced for thousands of years to preserve food and enhance flavor. Lactic acid bacteria dominate fermentations by rapidly producing acidity that inhibits spoilage microbes. Proper salting, temperature, and raw material quality influence bacteria growth. Starter cultures now control major commercial products like olives, cucumbers, sauerkraut, and kimchi. Researchers study bacteriocinogenic and probiotic strains that improve safety and nutrition of fermented foods.

ABSTRACT
The distinctive flavour of Tanzanian cocoa has recently been attracting the attention of the international
cocoa world, but still in Tanzania there is low or even no emphasis on cocoa farming in order to reach its
full potential. Objectives of this work were to sensitize the community towards use of locally processed
cocoa beans in preparing affordable drinks. This study had two sections namely; case study and sensory
evaluation aimed to test the consumer acceptability of the product. Factors relating and affecting the
growth of cocoa fruits was stipulated by observation and questionnairres in the study area. Based on the
results of this study, Most of the farmers they did not have land to cultivate cocoa, since it took about four
to five years to start harvesting after planting. This was too long times tended to bind the land, and make it
and hinder cultivation of other crops, especially for that farmer having small pieces of land. Other farmers
were not aware of cocoa farming. On the formulation of the product actually there was no clear formation
of cocoa powder during the milling and this might have been contributed by presence of high content of
lipid in the cocoa liquor. This suggests that the lipid should be extracted prior to milling in order to get
cocoa powder after grinding. The press–cake obtained is possible to be ground to easily get a cocoa
powder. This study showed that the cocoa beverage was so bitter, probably caused by incomplete drying
of cocoa beans and ineffective roasting of cocoa beans since during roasting an electrical laboratory oven
was used instead of using a roaster. The major causes for the bitterness could be due to lack of alkalization
process, which adjusts the level of acidity. Therefore, alkalization, removal of lipid and the use of roaster
should be subjects of further research for improving quality of cocoa powder.

CHAPTER ONE
INTRODUCTION
1.1 Background Information
Cocoa beans are the seeds of the tree Theobroma cacao. Each seed consists of two cotyledons (the nib) and
a small embryo plant, all enclosed in the shell, from which cocoa solids, cocoa butter and cocoa powders
are extracted. It is generally known to have originated from Central and Southern America. Currently, three
broad cultivars of cocoa are commonly recognized; Forastero, Criollo and Trinitario. The cultivars exhibit
differences in the appearance of pods, yields of beans, flavour characteristics and in resistance to pests and
diseases. In the 18th century, the Swedish botanist, Carolus Linnaeus, renamed the cocoa tree giving it the
Greek name Theobroma cacao, now its official botanical name, which literally means 'food of the Gods'
(Amorim et al., 2008). Cocoa trees resemble English apple trees; they grow best under the canopy of
tropical rainforests, seldom reaching more than 7.5 metres (25 feet) high. To flourish, they need to be
shaded from direct sun and wind, particularly in the early growth stages. The cocoa tree has broad, dark
leaves about 25cm long and pale-coloured flowers from which bean pods grow. The cocoa tree bears two
harvests of cocoa pods per year. Around 20 cm in length and 500 g in weight, the pods ripen to a rich,
golden-orange colour. Within each pod there are 20-40 purple, 2 cm long cocoa beans covered in a sweet
white pulp (Camu et al., 2008)
A native of the central and South American rainforests, cocoa trees are now cultivated in many tropical
locations around the world. In large Asian plantations, cocoa trees and coconut trees are planted together
and both crops are harvested commercially. Alternatively, forest trees are thinned out and the cocoa trees
are planted between established trees. Cocoa trees begin to bear fruit when they are three to four years old.
Only a small proportion of the flowers develop into fruit over a period of about five months.
The trees are carefully pruned so that pods can be more easily harvested. Each tree yields 20-30 pods per
year (Chieberle, 2008).The relative poverty of many cocoa farmers’ means that environmental
consequences such as deforestation are given little significance. For decades, cocoa farmers have
encroached on virgin forest, mostly after the felling of trees by logging companies. This trend has
decreased as many governments and communities are beginning to protect their remaining forested zones.
In general, the use of chemical fertilizers and pesticides by cocoa farmers is limited.
When cocoa bean prices are high, farmers may invest in their crops, leading to higher yields, which in turn
tend to result in lower market prices and a renewed period of lower investment. Cocoa production is likely
to be affected in various ways by the expected effects of global warming.
12. 12
Specific concerns have been raised concerning its future as a cash crop in West Africa, the current centre of
global cocoa production. If temperatures continue to rise, West Africa could simply become unfit to grow
the coveted beans (Bass, 2006).
The harvesting of cocoa pods is very labour-intensive. On West African small-holdings the whole family,
together with friends and neighbours help out. Ripe pods are gathered every few weeks during the peak
season. The high pods are cut with large knives attached to poles, taking care not to damage nearby flowers
or buds. The pods are collected in large baskets, which workers carry on their heads, and piled up ready for
splitting.The pods are split open by hand and the seeds or beans, which are covered with a sweet white pulp
or mucilage, are removed ready to undergo the two-part curing process - fermentation and drying. This
prepares the beans for market and is the first stage in the development of the cocoa powder (Markovic et
al,. 2011).

1.2 Problem Statement and Justification
Cocoa is one of the most important agricultural export commodities in the world and forms the backbone
of the economies of some countries in West Africa, such as Cote d’Ivoire and Ghana. In Ghana, cocoa has
been labeled ‘the golden pod’ owing to the pivotal role it plays in the nation’s economy. It is cultivated on
about 1.5 million hectares of land by some 800,000 families in six out of the ten regions. It is cultivated
almost exclusively by small-holder farmers with average farm sizes of about 4.0 ha and means production
yields of 246.4 kg/ha of Forastero varieties (Afoakwa, 2010). Research reveals that cocoa beans are
perhaps the best source of antioxidants, containing up to ten percent antioxidant concentration levels.
Antioxidants have several health benefits. They protect against cell damage and reduce the risks of several
kinds of cancer. Antioxidants also help regulate cholesterol levels. That is three times more antioxidants
than green tea. Blueberries are often said to be a great source of antioxidants. However, while domestic
blueberries have 32 antioxidants and wild blueberries 61, cocoa beans have 62 (Afoakwa, 2010).
In Tanzania, cocoa was introduced in the 1950s, and was being grown commercially within a decade.
Although it tends to be considered a relatively minor non-traditional cash crop, it currently supports an
estimated 25,000 farmers and their families (around 100,000 people)
(Ndunguru et al., 2012). At the moment, around 80% of the country’s crop comes from a single district
Kyela in Mbeya region, others from Kigoma region and Turiani in Morogoro region, where conditions for
cocoa cultivations are near perfect. The distinctive flavour of Tanzanian cocoa has recently been attracting
the attention of the international cocoa world, but much is still needed for the country’s crop to reach its
full potential (Nyomora et al., 2012). Overall, the relatively small areas under cocoa cultivation reflect the
acute shortage of land like in Kyela thus preventing the expansion of cocoa farms in the district.
Industrially processed cocoa beans, in their packaged form, are purchased at health stores but with high
price. Thus, it becomes difficult for many people to purchase and consume them in that manner since their
income is low.
People of Tanzania consume mostly green tea and not locally processed cocoa beans that have more
antioxidants. This is because they are not aware of the locally processed cocoa beans that ensure even the
retention of these antioxidants. Thus, there is need to bring awareness and evaluating also the acceptability
of the locally processed cocoa beans in preparing beverage (drinks) and this will expand the market while
raising the production and farming among the farmers in Tanzania, Since locally processed cocoa beans
will be sold at a relatively lower price and approximately every household could afford to purchase and
use.
14. 14
In Tanzania, cocoa is not consumed locally; the beans are merely harvested, fermented and sun-dried
before being shipped overseas to cocoa consuming countries. Then, the beans are sent to cocoa-processing
plants to be cleaned, roasted, winnowed, alkalised, milled, pressed, pulverised and otherwise transformed
into finished or semi-finished products like cocoa butter, powder, or liquour. These conventions deprive
farmers of the wealth of value-added practices. Constraints facing growers in Tanzania towards the quality
of the cocoa bean can be greatly enhanced by how it is tended, yet much of the country’s cocoa does not
yet reach its full potential because of poor planting, cultivating and processing techniques (Nyomora et al.,
2012).
1.3 Study Objectives
1.3.1 General objective

CHAPTER TWO
LITERATURE REVIEW
2.1 Nutrient Contents of Cocoa Beans
2.1.1 Tocopherol (vitamin E)
According to Nebesny et al. (2014), the total tocopherol (vitamin E) content in cocoa beans is at a level of
100–300 mg/kg fat. Tocopherols are strong natural antioxidants protecting the body from the negative
impact of free radicals and other reactive forms of oxygen. Plant sterols reveal the protective effect on the
oxidation of lipids due to the synergistic interactions with tocopherols, also during their thermal processing
(Oracz et al., 2014).According to Hurst et al., (2011) the antioxidant activity in cocoa powder, are stable
over typical shelf lives of one year under controlled storage and over 2 years in ambient storage in the
laboratory.
2.1.2 Phytosterols
The seeds of the cacao tree are also a rich source of phytosterols (200–300 mg/100 g fat) as well as in free
and esterified forms. The diet rich in phytosterols reduce the level of LDL cholesterol in blood serum by
inhibiting its absorption helps in prevention of hypercholesterolemia and cardio‐vascular system diseases.
Besides, these compounds improve the function of the urinary system and eliminate symptoms of the
prostate gland enlargement (Oracz et al., 2014).
2.1.3 Lipids
Crude fat level greatly differs among the variety and region of cultivation of cocoa beans, the highest value
being 59.32% and the lowest 53.08%. Example the Forastero variety from Ecuador contains much less
crude fat than Forastero beans variety from Brazil(Oracz et al., 2014). Total lipid content of fermented
cocoa beans is lower than that on unfermented beans. This is due to the presence of fatty acids produced
from fermentation process that stimulate lipid hydrolysis into fatty acids and glycerol (Wood, 1985).
During fermentation process, lactic acid bacteria homo-fermenter transforms glucose into lactic acid.
Lactic acid bacteria hetero-fermenter transforms glucose into lactic acid, alcohol, acetic acid
(Winarno,1991) .The study done by Retnowati et al. (2000) also noted that the total lipid content of
fermented cocoa beans is lower than that of unfermented beans.
16. 16
2.1.4 Phenolic compounds
Phenolics in cocoa (Theobroma cacao) and cocoa products can be classified into three main groups:
flavan-3-ols (37%), anthocyanins (4%) and proantho-cyanidins (58%). According to Markovic et
al.,(2011) the unfermented cocoa bean contains about 120–180 g/ kg of phenolic compounds,with
epicatechin, Catechin, gallocatechin, epigallocatechin, epicate-chin-3-gallate and numerous procyanidins.
The phenolic content of raw cocoa beans differs substantially from those in cocoa powder, cocoa liquor or
chocolate. Their content and concentration depend on cocoa bean variety, degree of ripeness, processing
and storage.
2.2 Processing of Cocoa Beans
2.2.1 Industrial processing of cocoa beans
A cocoa processing plant transforms cocoa beans into three main components: cocoa liquor, cocoa butter
and cocoa powder. These components can be used to make different products. Cocoa liquor is used with
other ingredients, to produce chocolate (Kaplinsky, 2004). Cocoa powder can be used as an ingredient in
almost any foodstuff. For example, it is used in chocolate flavoured drinks, preparation of tea as breakfast,
chocolate flavoured desserts such as ice cream and mousse, chocolate spreads and sauces, and cakes and
biscuits (State, 2015) Cocoa beans undergo several important steps to enhance and capture their flavour
(Fig. 2). The beans are first removed from the cocoa pod, then fermented, dried, roasted, and finally
cracked and winnowed to remove the bean shell. This produces cocoa nibs, which are ground or milled into
cocoa mass or liquor (Afoakwa, 2010).

2.2.2 Local Processing of Cocoa Beans.
Local processing of cocoa beans is relatively similar to that of industrial processing except that there is no
alkalisation and pulvesation in local processing of cocoa beans (Refer to the figure 3 ).That is, the cocoa
beans are harvested, fermented, dried, roasted, winnowed, milled and lastly turned to cocoa powder. After
pod harvest, beans and adhering pulp are transferred to heaps, boxes or baskets for fermentations lasting
from 5 to 6 days. Heap fermentation of beans is covered with banana leaves (Afoakwa, 2010).
Fig.3. Local and necessary steps of cocoa beans processing (Afoakwa, 2010)
After fermentation, the beans are removed from the heaps or boxes and dried in the sun on raised platforms
covered with mats or on the ground until fully dried within 7–8 sunny days.
After fermentation and drying, the target for cocoa beans is approximately 6–8% moisture contents. For
storage and transport, moisture content should be less than 8% (Fowler et al., 1998). Indicators of well-
dried, quality beans are good brown colour and low astringency and bitterness and an absence of off-
flavours such as smoky notes and excessive acidity (Afoakwa, 2010), then cocoa beans is milled to get the
cocoa powder ready for preparation of the affordable drink. The appearance of the local and industrially
processed powders tend to differ as seen in Fig. 4, below,

2.3 Roasting, Alkalisation, Drying and Fermentation on Cocoa Beans Processing
2.3.1 Roasting
Roasting of the fermented seeds fulfils mainly two purposes, the removal of undesired compounds with
low boiling points, such as acetic acid and the formation of the typical roasty, sweet odourants of cocoa
(Hurst et al., 2011). Whole bean roasting loosens the shell, which is then readily removed in winnowing.
Prior to roasting, cocoa beans have bitter, acidic, astringent and nutty flavours. Roasting further diminishes
acidity-reducing concentrations of volatile acids such as acetic acid (Beckett, 2000; Granvogl et al., 2006;
Ramli et al., 2006) but not non-volatiles such as oxalic, citric, tartaric, succinic and lactic acids (Afoakwa,
2010).
2.3.2 Fermentation
The attractive aroma of cocoa powder is a result of both, fermentation and roasting and is considered to be
the most important with respect to flavour formation (Daniel et al., 2009). During fermentation, aroma
precursors, such as free amino acids, short-chain peptides and reducing sugars are formed from which the
typical cocoa aroma is suggested to be generated during the subsequent roasting process (Chieberle, 2008).
2.3.3 Drying
Drying, decreases acidity, astringency and bitterness in cocoa beans. The number of days required for
effective drying varies, according to the weather conditions of the area. In the forest regions moist climate
posed a great challenge during drying. In the Western Region where the atmosphere remains relatively
humid for a longer period, six (6) days while in the Ashanti Region with relatively lower humidity 4 to 5
days were enough for effective drying. In protecting the drying cocoa beans against rains, especially in the
night, farmers adopted precautionary measures. Farmers spread polyethylene material over the cocoa beans
on days when rainfall appeared to be likely (Owusu, 2015).
2.3.4Alkalisation
Alkalisation is carried out primarily to change colour but also influence flavour of cocoa powder. This
process is common for cocoa products such as drinks to enhance dispersibility, solubility or suspension in
water, in baking or coatings. The process consists of treating cocoa beans, nibs, liquor, cake or powder with
solutions or suspensions of alkali, usually potassium or sodium carbonate, other alkalis may also be
used(Afoakwa, 2010).

SAMPLE KEY;
A = cocoa drink per cup with 0 and 1 number of tea spoon of sugar and cocoa respectively
B = cocoa drink per cup with 1 and 2 number of tea spoon of sugar and cocoa respectively
C = cocoa drink per cup with 2 and 1 number of tea spoon of sugar and cocoa respectively
D = cocoa drink per cup with 2 and 2 number of tea spoon of sugar and cocoa respectively
Mean scores with the same superscript in a column are not significantly difference (P ≥ 0.05).
Results of the sensory evaluation showed that sample C which was formulated by having cocoa drink per
cup with 2 and 1 spoons of tea and sugar and cocoa, respectively had significant differences at (P ≥ 0.05)
compared to all the remaining samples in terms of taste, sweetness and colour. From the results, sample C
was more acceptable than other samples (sample A, B and D) in terms of aroma, sweetness and taste.
4.1.2.1 Colour
Colour is a sensation that forms part of the sense of vision and judges the appearance of a food. From
Table …, there were significant differences (P < 0.05) between the samples in colour intensity of the cocoa
beverage. According to the results, sample C showed a significant difference from all samples remained.
This indicated that the rest of samples A, B and D were equally not accepted by all panelists in terms of
colour.
26. 26
4.1.2.2 Taste
There was a significant (P< 0.05) difference in taste between sample C with other samples A, B, and D.
This indicated that only sample C was highly accepted in term of taste by panellists.
4.1.2.3 Flavour
The results showed that the flavour mean score of the samples showed no significant (P> 0.05) differences
of the aroma attribute between the samples. The flavour of the entire formulations was appreciated by all
the panellists.
4.1.2.4 Sweetness
From Table 3, there were significance differences (P < 0.05) between the samples in intensity of sweetness
of the cocoa beverage. According to the results, sample C was sweeter than others and showed significant
difference from all the remaining samples. This indicated that regarding sweetness, the rest of samples A,
B and D were equally not accepted by all panelists.
4.1.2.5 General acceptability
Overall acceptability of the sample, there was a significant difference in general acceptability at (P< 0.05)
in all attributes among the samples. Sample C was more accepted than other samples. This indicated that
sample C was generally accepted in all attributes compared to other samples A, B, and D. Sample C was
generally more accepted may be due to its taste and sweetness.
4.2 DISCUSSION
4.2.1 Discussion of survey results
Basing on the results of case study on awareness, acceptability and keeping quality of locally processed
cocoa beans for beverage preparation conducted Turiani village in Morogoro region, in which thirty
farmers were interviewed, this was a summary of the coclusions made. Most of the farmers they did not
have land to cultivate cocoa. It took about four to five years to start harvesting after planting. This was too
long a time tended to bind the land and make it and hinders cultivation of other crops, especially for those
farmers having small pieces of land. Other farmers were not aware of cocoa farming. Even for those who
were cultivating the crop, they did not have skills and enough knowledge on cocoa farming.
27. 27
Marketing system of cocoa in Turiani Morogoro was seen to be a challenge, since only one entrepreneur
basing on cocoa beans had constructed a building like (godown) where s farmer tend to sell their cocoa
beans after drying. Less effort from the government toward cocoa farming in Turiani Morogoro was seen
to be a problem, since there was poor infrastructure of roads. Drying cocoa beans in the sun by spreading it
on the ground contributed greatly to effects on the quality of cocoa beans, by increasing contamination
with sand, stones, dust and microbes as in Fig. 6.
Figure 6. Sun drying of cocoa beans in Turiani Morogoro
Per capita income for those cocoa farmers was 5$ and above, while for those non-cocoa farmers (who
cultivated other crops like yam and pan rice) was 1$-1.5$. Actually this can be generalized that cocoa
farming had greatly improved the life standard among the few farmers in Turiani, who cultivated the crops.
For this case there was no any factory even for adding value to the cocoa beans before selling. Only that
entrepreneur provided grant, subsides and loans to particular farmers who wanted to invest in cocoa, but
nothing like this came from the government as shown in Fig. 7.

4.2.2 Discussion on sensory evaluation
Grinding and or milling using milling machine is applied to dried cereals like rice and maize in order to get
powder. As after drying, it is possible to get powder of these cereals, it was a different case with cocoa
beans. Fermented and dried cocoa beans immediately after roasting were milled but there was no cocoa
powder produced, This was due to presence of high amount of lipid in cocoa beans thus extraction of this
lipid in the cocoa liquor (after milling) should be done in order to get a press -cake that can be grinded to
get a clear cocoa powder. For this study sieving of the milled cocoa beans was done so as to obtain a clear
beverage for sensory evaluation test.
Measuring the liking of a set of products using selected panelists allows an understanding of the influence
of sensory properties on acceptance and preference of the product to be developed. For measuring
consumer responses to product features, products are rated for degree of liking under controlled conditions.
From this study it was shown that the cocoa beverage was so bitter, this might be due to incomplete drying
of cocoa beans, ineffective roasting of cocoa beans since during roasting an electrical laboratory oven was
used instead of using a roaster but also the major cause for that bitterness was may be lack of alkalization
process which adjusts the level of acidity as the literature reported (Afoakwa, 2010).

CHAPTER FIVE
CONCLUSION AND RECOMMENDATION
Cocoa is one of the most important agricultural export commodities in the world and forms the backbone
of the economies of some countries in West Africa, such as Cote d’Ivoire and Ghana. The distinctive
flavour of Tanzanian cocoa has recently been attracting the attention of the international cocoa world, but
much is still needed for the country’s crop to reach its full potential. Overall, the relatively small areas
under cocoa cultivation reflect the acute shortage of land like in Turiani, thus preventing the expansion of
cocoa farms in the district. Industrially processed cocoa beans, in their packaged form, are purchased at
health stores but with high price.
Thus, it becomes difficult for many people to purchase and consume them in that manner and in the
meantime their income is low. In Tanzania, cocoa is not consumed locally; the beans are merely harvested,
fermented and sun-dried before being shipped overseas to cocoa consuming countries. Then, the beans are
sent to cocoa-processing plants to be cleaned, roasted, winnowed, alkalised, milled, pressed, pulverised and
otherwise transformed into finished or semi-finished products like cocoa butter, powder, or liquor. These
conventions deprive farmers of the wealth of value-added practices.
Fermented and dried cocoa beans immediately after roasting and milling need to have the lipid extracted in
order to get cocoa powder after grinding. Press–cake obtained is possible to be ground to get a clear cocoa
powder. In case of findings from this study, the cocoa beverage was so bitter, possibly caused by
incomplete drying of cocoa beans, ineffective roasting of cocoa beans and lack of alkalization process.
Therefore, alkalisation, removal of lipid and the use of roaster are recommended for further research.
