Cocoa, Cocoa

The figure gives the production estimates for the 2006/7 season from the International Cocoa Organization. The percentage is the proportion of the world's total of 3.5 million tonnes for the relevant period.

The pulp and seeds are then piled in heaps, placed in bins, or laid out on grates for several days. During this time, the seeds and pulp undergo "sweating", where the thick pulp liquefies as it ferments. The fermented pulp trickles away, leaving cocoa seeds behind to be collected. Sweating is important for the quality of the beans, which originally have a strong bitter taste. If sweating is interrupted, the resulting cocoa may be ruined; if underdone the cocoa seed maintains a flavor similar to raw potatoes and becomes susceptible to mildew.

In a factory, the beans are washed and roasted. Next they are cracked and then de-hulled by a "winnower". The resulting pieces of beans are called nibs, and are ground using various methods into a thick creamy paste, known as chocolate liquor or cocoa paste.

Regular (nonalkalized) cocoa is acidic, so when cocoa is treated with an alkaline ingredient, generally potassium carbonate, the pH increases. This process can be done at various stages during manufacturing, including during nib treatment, liquor treatment or press cake treatment.

The researchers found that the Kuna Indians living on the islands had significantly lower rates of heart disease and cancer compared to those on the mainland who do not drink cocoa as on the islands. It is believed that the improved blood flow after consumption of flavanol-rich cocoa may help to achieve health benefits in hearts and other organs. In particular, the benefits may extend to the brain and have important implications for learning and memory.

According to research at Cornell University, cocoa powder has nearly twice the antioxidants of red wine, and up to three times the antioxidants found in green tea.

However, chocolate and cocoa contain a high level of xanthines, specifically theobromine and to a much lesser extent caffeine, that are detrimental to the health of many animals, including dogs and cats. While these compounds have desirable effects in humans, they cannot be efficiently metabolized in many animals and can lead to cardiac and nervous system problems, and if consumed in high quantities, even lead to death. However, since the mid-2000s, some cocoa derivatives with a low concentration of xanthines, have been designed by specialized industry to be suitable for pet consumption, enabling the pet food industry to offer animal safe chocolate and cocoa flavored products.

Additionally, consumers are becoming increasingly interested in the environmental impact of the production of cocoa, as well as what they perceive as the negative social impact of its production.

The mission of the Roundtable is to establish a participatory and transparent process towards economic, environmental and social sustainability in the global cocoa economy. The 1st Roundtable in 2007 brought together more than 200 stakeholders representing 25 countries, including cocoa farmers, government officials from cocoa producing and consuming countries, traders, chocolate manufacturers, donor organizations and national and international NGOs.

The London market is based on West African cocoa and New York on cocoa predominantly from South East Asia. Cocoa is the world's smallest soft commodity market.The futures price of cocoa butter and cocoa powder is determined by multiplying the bean price by a ratio. The combined butter and powder ratio has tended to be around 3.5. If the combined ratio falls below 3.2 or so, production ceases to be economically viable and some factories cease extraction of butter and powder and trade exclusively in cocoa liquor.
