Abstract

Xanthine stimulants are extracted from a cocoa material containing a fat by adding water to the cocoa material for swelling it with at least 0.1 part by weight of water per part by weight of cocoa. The swollen material is then contacted with a food-acceptable solvent gas which is supercritical in respect to temperature and pressure, after which the solvent gas containing the stimulants is separated from the swollen cocoa material which thereupon has a reduced content of stimulants.
