This chart shows cocoa powder import and export quantity details by country.
Cocoa powder comes from cocoa beans that grow in pods on the cacao tree. The beans are fermented, dried, roasted and cracked; the nibs are ground to extract about 75% of the cocoa butter, leaving a dark brown paste called chocolate liquor. After drying again, the mass is ground into powder (unsweetened cocoa). Dutch cocoa is treated with an alkali to neutralize the cocoa's natural acidity.
