Abstract
Abstract An improved alkalized cocoa powder is described having a desirable dark color but avoiding the unpleasant taste and flavor which is often obtained with intensely alkalized cocoa powders. The claimed alkalized cocoa powder has a pH of 7.5 or less; a ratio of pH: alkalinity of the ash below 0.046; color coordinates L between 9.0 and 14.0, a between 4.0 and 8.0, and b between 2.0 and 6.0; and neither more nor other acid radicals present than those which are naturally present in fermented cocoa.
