Cocoa beans (raw beans) contain 5.58% water, 50.29% fat, nitrogen 14. 19%, theobromine10.55%, other non-nitrogen substances 13.9 1%, and starch 8. Cocoa beans also contain nerve center stimulants such as caffeine and tannin, which has a great relationship with the color, aroma and taste of chocolate.
The melting point of cocoa butter is close to human body temperature, which has the characteristics of melting in the mouth and maintaining a certain hardness at room temperature. It also has a unique cocoa flavor, high nutritional value and is not easy to oxidize. It is the main raw material for making chocolate.
Cocoa cake can be made into cocoa powder, which is rich in carbohydrates, fat, protein and vitamin B.
Cocoa trade
Cocoa beans from Ghana are traditionally transported and stored in burlap bags, where they are vulnerable to pests. The use of methyl bromide for fumigation is worldwide. By 20 15, other cocoa protection technologies used for transportation and storage will be phased out, including the application of pyrethroids and sealed storage in sealed bags or containers with reduced oxygen concentration.
Safe long-term storage is beneficial to the trading of cocoa products in commodity exchanges.
Cocoa beans, cocoa butter and cocoa powder are traded in the futures market. The London market is mainly cocoa from West Africa, while the new york market is mainly cocoa from Southeast Asia. Cocoa is the smallest soft commodity market in the world.
The futures price of cocoa butter and cocoa powder is determined by multiplying the price of cocoa beans by a ratio. The combination ratio of butter and flour is often around 3.5. If the comprehensive ratio is lower than about 3.2, production is no longer economically feasible, and some factories stop extracting butter and powder and only trade cocoa liquid.
The global cocoa surplus and deficit change year by year, while the total output and grinding amount increase steadily. These fluctuations will affect the price of cocoa and every participant in the global cocoa supply chain.
