Cacao Tree

The tree is often grown in the shade of other trees.

It can be as tall as 40 feet and has fruit (pods) which are more than a foot long.

The fruit may be brownish-yellow to purple, and contain 20-40 seeds or cacao beans in a pink, sweet-sour pulp.


The cacao tree is cultivated in many countries, but today the leading suppliers are Ivory Coast, Ghana, Indonesia, Nigeria, Brazil, Cameroon, Ecuador, Dominican Republic and Papua New Guinea.

fermentation of cacao
Fermentation of Cacao

The fermentation process transforms the flavor to what we associate with cocoa and chocolate.

Without the fermentation process there will not be any chocolate flavor.

When the fermentation is terminated the cacao beans are sun-dried. At this stage the smell of cocoa can be observed.
After roasting and winnowing (removing the outer shell from the cacao beans) they are ground making cocoa liquor, see the left side of the picture.
nutrition facts
Nutrition Facts


  • Cocoa beans contain approximately 50% fat. It is primarily comprised of two saturated fatty acids, and the monounsaturated oleic acid.
  • Cocoa butter and chocolate do not raise blood cholesterol.
  • The cacao bean contains quite a lot of carbohydrates, but most of it is starch, soluble dietary fibers and insoluble dietary fibers.
  • A very small proportion is simple sugars.
  • Sugar is added during the manufacture of chocolate.
  • Cocoa beans contain polyphenols (similar to those found in wine) with antioxidant properties which are health beneficial.
  • These compounds are called flavonoids.
  • The flavonoids also reduce the blood's ability to clot and thus reduces the risk of stroke and heart attacks.
  • Theobromine is a very mild stimulant with a mild diuretic action (increases the production of urine).
  • Please note that theobromine can be toxic to animals like dogs, cats, parrots and horses.
  • Cocoa beans contains a very low amount of caffeine, much less than found in coffee, tea and cola.
  • Chemicals found in chocolate target the same brain receptor system as marijuana.
  • It activates the brain cells the same way as THC (tetrahydrocannabinol) does in marijuana.
  • But, a 130 lb person would have to eat a whopping 25lb. of chocolate to get a "buzz."
  • White chocolate does not contain this substance.
  • Phenylethylamine is a slight antidepressant and stimulant similar to the body's own dopamine and adrenaline.
  • Phenylethylamine is known as the "love drug" and is thought be be the reason why chocolate is said to be an aphrodisiac.
  • Cocoa and chocolate can increase the level of serotonin in the brain.
  • Serotonin levels are often decreased in people with depression and in those experiencing PMS symptoms.
  • Chocolate consumption stimulates the release of serotonin into the body, which combine to produce a relaxed or euphoric feeling.
  • This may explain why some people crave chocolate when they're feeling depressed.

  • A, B1, B2, B3, C, E and pantothenic acid.
Is chocolate fattening?

  • he used about 100 kg of chocolate and 30 kg of cocoa butter to make the model, which took five people one week to assemble.
what is fair trade
  • Fair Trade fights poverty by providing sustainable livelihoods.
  • Fair Trade is trading partnership, a sustainable business model, that establishes better trading conditions to, and secures the rights of, marginalized producers, artisans and workers.
If consumer demand for Fair Trade chocolate increases, perhaps chocolate companies will alter their practices.
  • Thus, buying Fair Trade chocolate can put an end to the disastrous cycle of poverty and child endangerment.
