20100129521 | Heat Processed Products Having Altered Monomer Profiles and Processes For Controlling The Epimerization of (-)-Epicatechin and (+)-Catechin In The Products - A method for controlling the epimerization of (−)-epicatechin to (−)-catechin in an epicatechin-containing product, preferably an edible product, or of (+)-catechin to (+)-epicatechin in a catechin-containing product, comprises the step of heating the product at a temperature of up to about 200° C. and at a pH of up to about 8. Under either method, the epimerization may be carried out in an open food processor in a reduced oxygen atmosphere or in a closed food processor. The edible product may be pasteurized, boiled, or sterilized during the epimerization. Epimerization is minimized by lowering the heating temperature, by lowering the pH, and/or by lowering the heating time. Conversely, the epimerization is maximized by increasing the heating temperature, by increasing the pH, and/or by increasing the heating time. The edible product may contain or be a fruit product, a vegetable product, a cereal product, a bean product, a nut product, a spice product, or a botanical product. | 05-27-2010 |

20120309991 | METHODS FOR EXTRACTING COCOA PROCYANIDINS AND EXTRACTS THEREOF - 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, 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 result in the preferential extraction of the higher or lower oligomers. A preferred extraction method is counter-current extraction method. | 12-06-2012 |
