SOLUBLE DIETETIC FIBER OF GRAINS OF AVENA AND CEBADA, METHOD FOR PRODUCING A FRACTION RICH IN BETA-GLUCANO AND USE OF FRACTION IN FOOD, PHARMACEUTICAL AND COSMETIC PRODUCTS.

摘要

A procedure for the extraction of a soluble dietary fiber complex of oat and barley grain using an enzymatic hydrolysis treatment, characterized by the fact that the heat-treated grain is not ground and any depleted endosperm fractions thereof rich in ß- Glucans are recombined without further heat treatment, dispersed in water and then subjected to enzymatic treatment with β-glucanase-free starch degrading enzymes, followed by an optional step of enzymatic inactivation by wet heat treatment, whereby the hydrolyzate mixture spontaneously forms at least one upper aqueous viscous layer on a second aqueous layer, it is subjected to a separation process to isolate said at least one aqueous viscous upper layer comprising the soluble dietary fiber complex, which contains more than 20% of β -glucan in percentage of dry matter.
