Cocoa contains phytochemicals like flavanols, procyanidins, and other flavonoids, and flavanol-rich chocolate and cocoa products may have a small blood pressure lowering effect.
The beans also contain theobromine and a small amount of caffeine.
Environmental issues due to cocoa production
Deforestation due to cocoa production remains a concern, especially in West Africa. Sustainable agricultural practices, such as agroforestry, can support cocoa production while conserving biodiversity.
How chocolate is prepared from cocoa beans?
Cocoa beans are the main ingredient for making chocolate. To produce 1 kilogram of chocolate, around 300 to 600 cocoa beans are processed. The beans are roasted, cracked, and deshelled, resulting in pieces called nibs, which are ground into a thick paste known as chocolate liquor or cocoa paste. The liquor is processed into chocolate by adding cocoa butter, sugar, and sometimes vanilla and lecithin.
Cocoa cultivation in India
It is cultivated in coconut and arecanut plantations on large scale from 1970 onwards.
It is grown as an under- storey intercrop with sufficient shade in southern states (mainly cultivated in Karnataka, Kerala and Tamil Nadu) of India.
Time and method of planting
Cocoa is a shade loving plant. During its seedling period it requires about 50% shade and later the shade requirement is about 40%. The plant is grown as a mixed crop with other plants like spices and rubber mainly under rainfed conditions.
Cocoa is planted as an intercrop in coconut and arecanut gardens.
Irrigation in cocoa
Cocoa is usually grown in areas where water availability is adequate. Cocoa plants are sensitive to drought, irrigation in such cases becomes essential.
Harvesting and Processing
Cocoa produces flowers from the 3rd year of planting onwards and economic yield starts from 5 th year.
