  • Publication number: 20220007693
    Abstract: A process for preparation of cereal fractions. The process comprises wet milling of oat grains or barley grains in the presence of an enzyme composition derived from malt; and when oat grains or barley grains are wet milled, optionally isolating, from the wet milled grains, a beta-glucan enriched fraction. Liquid and solid food products obtainable by the process.

  • Patent number: 7910143
    Abstract: 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.

  • Patent number: 7858139
    Abstract: The present invention relates to a process for preparing a stable emulsion/dispersion of an oil and an aqueous phase, wherein a ?-glucans rich substrate, derived from oat or barley grain, is the active emulsifying component.

  • Patent number: 7709033
    Abstract: 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.

  • Publication number: 20050136162
    Abstract: 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.
