Abstract
A deep red or black dutched cocoa is produced by alkalizing cocoa presscake at between 150.degree. to 300.degree. F., 10 to 200 p.s.i. and 5 to 180 minutes. During the alkalization reaction, the reaction vessel is partially vented and an oxygen-containing gas is fed to the reaction vessel to maintain pressure and effect headspace changes at the rate of at least 3 per hour.
