摘要

The method involves peeling or mashing the seed, cooling, removing the pulp, scalding, drying, cleaning, dehusking, removing the fat, stabilizing and grinding. A hydroalcoholic extraction is performed, and the solid and liquid phases are separated. The liquid extract is concentrated and dried and a powdered hydroalcoholic extract is obtained with a polyphenol content of 35 to 55 per cent. The liquid-liquid extraction is performed and the extract is separated. A powdered semi-purified extract is obtained with polyphenol content of 20 to 45 per cent. An organic fraction, from which, after concentration and drying, a powdered purified extract with a polyphenol content of 60 to 90 per cent, is obtained. The cocoa extracts obtained are catechin, epicatechin, unfermented procyanidine B1 and procyanidine B2.
