Abstract
For improving the taste and dispersibility of cocoa and for obtaining alkalized cocoa to which is imparted red coloration for obtaining a wide range of colors in shades of red and brown, cocoa meal or liquor and an alkalizing agent in aqueous phase are mixed and heated in an enclosed vessel under a pressure of from above 1 atmosphere to 3 atmospheres at a temperature below 110.degree. C. without evaporation of water while introducing an oxygen-containing gas into the vessel during at least a part of the mixing and heating for maintaining the excess pressure. After the cocoa is alkalized, water is evaporated from it.

A process for alkalizing cocoa for improving taste and dispersibility and for obtaining alkalized cocoa having a range of colors in shades of red and brown comprising:
- mixing nad heating cocoa and an alkalizing agent dissolved in water in an enclosed vessel at a temperature below 110.degree. C. under a pressure in the vessel of from above 1 atmosphere to 3 atmospheres without evaporation of water while introducing an oxygen-containing gas during at least a part of the mixing and heating to maintain the pressure of from above 1 atmosphere to 3 atmospheres for alkalizing the cocoa;
- and then
- evaporating the water from the alkalized cocoa.
