Abstract: The present invention relates to obtaining bioactive peptides from plant raw materials, specifically cocoa extracts, by means of enzyme treatment. Said biopeptides have angiotensin converting enzyme (ACE) and prolyl endopeptidase enzyme (PEP) inhibitory activity in vitro and/or antioxidant activity in vivo, being able to be used in the food, dietetic and pharmaceutical industry.

Abstract: The invention relates to a method for obtaining fibre-rich cocoa with low carbon hydrate and methylxanthine contents and resulting cocoa powder which is suitable for animal feed. The inventive method includes the following main steps in which: the whole cocoa beans undergo cleaning, deffating, treatment with alpha-amylase, centrifugation, extraction-washing and subsequent centrifugation, separation, drying and grinding.

Abstract: Process for obtaining cocoa polyphenol concentrate includes: a) subjecting unfermented cocoa beans to a blanching step in water at a temperature ranging from 85-100° C. for a period ranging from 3 to 15 minutes to give unfermented cocoa beans with reduced polyphenol oxidase activity; b) drying the unfermented cocoa beans at a temperature of less than 85° C. to obtain dried unfermented cocoa beans with a moisture content of no more than 15%; c) subjecting the dried unfermented cocoa beans to a particle size reduction step to obtain dry unfermented cocoa bean intermediate whereby at least 99 wt % of the product has a particle size less than or equal to 300 ?m; e) extracting polyphenols from the dry unfermented cocoa bean intermediate to give a cocoa polyphenol extract and extracted solids; d) concentrating the cocoa polyphenol extract to yield a cocoa polyphenol concentrate; and carrying out a defatting step prior to step d).
