Cocoa shells, waste products that are often burned for fuel at cocoa processing factories, actually are rich in fiber and antioxidants and have potential as a food and beverage ingredient, says Barry Kitchen, executive chairman of Daintree Estates. He estimates Daintree is about three months away from commercializing a cocoa shell extract that can be used in beverages and chocolate. Barry Callebaut filed a patent earlier this year for a process that grinds cocoa shells into powder that can be used as a cocoa replacer.
