A METHOD FOR PRODUCING A POLYPHENOLIC COMPOSITION FROM BARLEY MALT

Method for the production of a polyphenolic composition from barley malt, including the fundamental steps of: grinding of the malt grains and splitting into two portions, 20% and 80%; mixing each of the two portions with water to obtain an A mixture and a B mixture, the A mixture being prepared with the 20% portion to obtain a mixture of the malt in water at a final concentration between 9.5% and 20%, the B mixture being prepared with the 80% portion to obtain a mixture of the malt in water at a final concentration between 33% and 60%; thermal cycle; separation of the liquid component from the solid component; boiling of the liquid component and the addition of hops; rapid cooling of the wort; storage; in which said thermal cycle consists of a first phase and a second phase, in which the first phase applies to the 20% portion (Mixture A) and the second phase during which Mixture B is added to Mixture A. The relative polyphenolic composition obtained according to this method is characterized by the fact that it can be in liquid, powder, dry, and lyophilized form, its use and relative beverage or beer according to the present method not obtained with fermentation methods.
