SOLUBLE FOOD FIBER OF OAT AND BARLEY GRAIN, PRODUCTION METHOD OF FRACTION ENRICHED WITH BETA-GLUCAN AND USAGE OF THIS FRACTION IN FOOD, PHARMACEUTICAL AND COSMETICS PRODUCTS Russian patent published in 2009 - IPC A23L1/105 C08B37/00 

FIELD: food industry.

SUBSTANCE: invention relates to soluble food fibers (made of oat or barley grain) extraction method and treatment by fermentative hydrolysis. Milled oat or barley grain and any of its fractions combined by endosperm which are enriched by β-glucans are combined and dispersed in water without additional thermal treatment. After that it is fermentative process using enzymes which decompose starch with following possible stage of deactivation of enzymes by wet thermal treatment. After that hydrolysate mixture inadvertently or by centrifugal processing is divided into at least 3 separate fractions. The first fraction contains soluble food fibers complex, contains more than 20% of β-glucans as dry substance, second water fraction and third fraction containing most part of protein and oil together with dissoluble fiber material of milled grain. Besides the real invention relates to usage of obtained β-glucans.

EFFECT: proposed method allows to separate clean fraction, enriched with β-glucans.
