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