摘要:
A process for the fractionation of oilseed cakes and meals (e.g. rapeseed cake, soybean meal, and cottonseed cake) is disclosed. This invention describes a fractionation process, in which the said cake or meal is subjected to enzymatic treatment with polysaccharidases with intermittent wet milling, followed by heat treatment to facilitate separation of insoluble from soluble phase by centrifugal forces. Sequential centrifugation and ultrafiltration steps are carried out in order to yield a fibre-rich fraction, at least three protein-rich fractions, in the case of oilseed cakes at leas one emulsified oil fraction, a sugar-rich fraction, and a phytate-rich fraction. This invention also describes the use of the above-mentioned fractions in food, feed, nutraceutical and pharmaceutical applications.

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 fibre from oat and barley grains using enzymatic hydrolysis treatment, wherein the grain is milled and any endosperm depleted fractions thereof being rich in β-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 fibre 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, the invention further relates to applications of use of the 3-glucan derived, as well as a set-up for carrying out the process.
