PCT No. PCT/FI94/00212 Sec. 371 Date Dec. 4, 1995 Sec. 102(e) Date Dec. 4, 1995 PCT Filed May 27, 1994 PCT Pub. No. WO94/28742 PCT Pub. Date Dec. 22, 1994The subject of this invention is a method for producing a product with an enriched content of soluble dietary fiber, such as beta -glucan and/or pentosans from a raw material deriving from cereal grains, by using thermal, enzymatic or osmotic treatments or combinations of these. As a first step, suspending of milled cereal or a fraction of cereal in water and when needed, a limited proteolysis is performed in order to improve the solubility of the fiber. Temperature of the mixture is elevated, and the soluble fiber is precipitated with a polar organic solvent on solid carrier particles, which can derive from the raw material or are added in the suspension. A fine fraction, consisting primarily of starch, is separated from the more coarse fraction containing the precipitated fiber, by using methods based on the particle size or density. When processing materials rich in fat, the soluble fiber fraction is extracted with a concentrated polar organic solvent for removing the residual lipids, and the particles obtained are finally dried. |
