The search for a cocoa substitute was motivated by the rise in international demand for cocoa, Spada said. This rise in turn is due to the growing demand for chocolate without a corresponding growth in supply, as cocoa-producing countries fail to boost their output. Many Chinese and Indian consumers can afford chocolate for the first time. The world cocoa production has not kept up, and the commodity is increasingly scarce as a result.

According to the International Cocoa Organization, 4.568 million metric tons of cocoa beans were processed in the 2017-18 crop year. This was almost the same as the total world production (4.645 million mt). The leading producer in 2017-18 was Ivory Coast, which accounted for approximately 40 percent of the total, followed by Ghana, Indonesia, Ecuador, Cameroon, Nigeria and Brazil.
