Method of producing a bran product

摘要

The present invention relates to a method of manufacturing a cereal bran product containing beta-glucan. According to the method, a plastic mass is formed from cereal bran by means of a thermo-mechanical treatment, and the mass is brought into contact with an enzyme that breaks up beta-glucan, with or without an enzyme that breaks up starch. After inactivating the enzyme, the bran is dried and, when so needed, ground. The cereal bran product manufactured according to the method has an essentially inextensible structure in a water environment. The product is suitable to be added to aqueous foodstuffs or to foodstuffs, the manufacture of which employs water.

主权项

1. A method of manufacturing a cereal bran product containing beta-glucan, comprising the following stages:
pretreating the cereal bran, whereby the beta-glucan is brought out of the cereal bran; thermo-mechanically treating the cereal bran, whereby a plastic mass is formed from the cereal bran, wherein the thermo-mechanical treatment is carried out at two stages, wherein the thermo-mechanical treatment stages comprise an extrusion or an expansion process and wherein the moisture of the cereal bran at the thermo-mechanical treatment stages is 20-65% by weight; bringing the mass into contact with an enzyme that breaks up beta-glucan with or without an enzyme that breaks up starch; inactivating the enzyme(s); and drying the bran and, optionally, grinding the bran.
