    摘要： A process for the fractionation of valuable fractions from cereal brans (e.g. wheat, barley and oat brans, and rice polish) is described. In particular, this invention describes a two step process, in which the said bran is first subjected to a combination of enzymatic treatment and wet milling, followed by sequential centrifugation and ultrafiltration, which aims at physically separating the main bran factions, i.e. insoluble phase (pericarp and aleurone layer), germ-rich fraction, residual endosperm fraction and soluble sugars. A second step consists of fractionating cereal brans substantially free of soluble compounds, hence insoluble phase from the above-mentioned first step, by enzymatic treatment with xylanases and/or beta-glucanase and wet milling, followed by sequential centrifugation and ultrafiltration, which aims at physically separating the main fractions, i.e. insoluble phase (remaining cell wall components), protein-rich fraction, soluble hemicellulose and oligosaccharide, and therefore maximizes the extraction rate of valuable cell wall components and aleurone cells from previously cleaned bran.

    摘要： The present invention relates to a process for the extraction of soluble dietary fiber from oat and barley grains using enzymatic hydrolysis treatment, wherein the grain is milled and any endosperm depleted fractions thereof being rich in B-glucans are recombined, without further heat treatment, dispersed in water and then subjected to sequential enzymatic treatment with starch degrading enzymes, followed by an optional step of enzyme inactivation by wet heat treatment, and a subsequent step wherein the hydrolysate mixture is spontaneously or centrifugally separated into at least 3 distinct fractions: a first fraction, which comprises the soluble dietary fiber complex, containing more than 20% B-glucan on a dry matter basis, a second aqueous fraction, and a third fraction comprising most of the protein and oil together with the insoluble fibrous material from the milled grain.
