Concept
Theobroma cacao
Summary
Theobroma cacao (cacao tree or cocoa tree) is a small ( tall) evergreen tree in the family Malvaceae. Its seeds, cocoa beans, are used to make chocolate liquor, cocoa solids, cocoa butter and chocolate. The largest producer of cocoa beans in 2018 was Ivory Coast, at 2.2 million tons.
Its leaves are alternate, entire, unlobed, long and broad.
The flowers are produced in clusters directly on the trunk and older branches; this is known as cauliflory. The flowers are small, diameter, with pink calyx. The floral formula, used to represent the structure of a flower using numbers, is ✶ K5 C5 A(5°+52) (5).
While many of the world's flowers are pollinated by bees (Hymenoptera) or butterflies/moths (Lepidoptera), cacao flowers are pollinated by tiny flies, Forcipomyia midges in the subfamily Forcipomyiinae. Using the natural pollinator Forcipomyia midges for Theobroma cacao was shown to have more fruit production than using artificial pollinators.
The fruit, called a cacao pod, is ovoid, long and wide, ripening yellow to orange, and weighs about when ripe. The pod contains 20 to 60 seeds, usually called "beans", embedded in a white pulp.
The seeds are the main ingredient of chocolate, while the pulp is used in some countries to prepare refreshing juice, smoothies, jelly, and cream. Usually discarded until practices changed in the 21st century, the fermented pulp may be distilled into an alcoholic beverage. Each seed contains a significant amount of fat (40–50%) as cocoa butter.
The fruit's active constituent is the stimulant theobromine, a compound similar to caffeine.
The generic name Theobroma is derived from the Greek for "food of the gods"; from θεός (theos), meaning 'god' or 'divine', and βρῶμα (broma), meaning 'food'. The specific name cacao is the Hispanization of the name given to the plant in indigenous Mesoamerican languages such as kakaw in Tzeltal, Kʼicheʼ and Classic Maya; kagaw in Sayula Popoluca; and cacahuatl in Nahuatl meaning "bean of the cocoa-tree".
