Abstract
A process is described for selectively extracting cocoa procyanidins from an aqueous mixture of cocoa polyphenols by using a particular sequence of solvents to extract selected procyanidin monomers and/or oligomers. The solvents are n-butyl acetate, ethyl acetate, methyl acetate, diethyl ether, or mixtures of methyl acetate and diethyl ether. Preferably, the aqueous mixture of cocoa polyphenols is first extracted with n-butyl acetate. The mixtures of methyl acetate and diethyl ether are between 25:75 and 75:25 (v/v).
