Patent ID: 7709033

Claim:
A process for the wet fractionation of cereal bran obtained after a primary milling of one or more of the cereals of the group comprising wheat, barley, oat, rye and triticale resulting in the substantial removal of the endosperm, into protein, sugar and insoluble fractions, a process wherein bran substantially devoid of the endosperm is subjected to a first enzymatic treatment, utilizing a combination of enzymes of the group containing starch-hydrolysing enzymes, and aqueous wet milling, followed by a separating step whereby resultant aqueous slurry/suspension is separated into an insoluble fibrous fraction and a soluble fraction, whereby said soluble fraction is further separated by centrifugal forces into a germ-rich fraction and an endosperm- and sugar-rich fraction, said endosperm- and sugar-rich fraction is further separated into proteins and sugars and; said insoluble fibrous fraction containing a cleaned bran consisting of both insoluble pericap and aleurone fractions, is further subjected to a hydrolyzation by a second enzymatic treatment utilizing a combination of one or a mixture of enzymes of the group non-starch polysaceharidases, and aqueous wet-milling, and a subsequent step whereby the resultant hydrolysate is separated into an insoluble phase and a soluble phase.
