FIBRES ALIMENTAIRES SOLUBLES PROVENANT DE GRAINS D'AVOINE ET D'ORGE, PROCEDE DE PRODUCTION D'UN FRAGMENT RICHE EN .BETA.-GLUCANE ET UTILISATION DU FRAGMENT DANS DES PRODUITS ALIMENTAIRES, DANS DES PRODUITS PHARMACEUTIQUES ET DANS DES PRODUITS COSMETIQUES
The present invention relates to a process for the extraction of solubledietary fibre from oat and barley grains using a enzymatic hydrolysistreatment, wherein the grain is milled and any endosperm depleted fractionsthereof being rich in .szlig.-glucans are recombined, without further heattreatment, dispersed in water and then subjected to sequential enzymatictreatment with starch degrading enzymes, followed by an optional step ofenzyme inactivation by wet heat treatment, and a subsequent step wherein thehydrolysate mixture is spontaneously or centrifugally separated into at least3 distinct fractions: a first fraction, which comprises the soluble dietaryfibre complex, containing more than 20 % .szlig.-glucan on a dry matter basis,a second aqueous fraction, and a third fraction comprising most of the proteinand oil together with the insoluble fibrous material from the milled grain,the invention further relates to applications of use of the 3-glucan derived,as well as a set-up for carrying out the process.
