Abstract
A cocoa extract which is rich in procyanidin monomers and oligomers is made by extracting de-fatted, unroasted, unfermented cocoa beans with organic solvents. The yield of procyanidins in an extract varies with type of solvent used, extraction temperature, extraction pH and whether or not the solvent is an aqueous solvent solution. Extraction parameters can be optimized to increase procyanidin yield, and different conditions and/or solvents result in the preferential extraction of the higher or lower oligomers. A preferred extraction method is counter-current extraction method.
