Abstract

The invention relates to the technical field of plant effective component refining and processing, in particular to a method for extracting beta-glucan in oat and oatmeal processing byproducts. The method for extracting the beta-glucan in the oat and oatmeal processing byproducts includes pretreating raw materials; extracting the beta-glucan and removing starch; removing proteins; carrying out concentration and ethanol precipitation; removing heteropolysaccharides; removing ammonium sulfate by means of ethanol precipitation; carrying out freeze drying to obtain extract. The method has the advantages that the oat and oatmeal processing byproducts are smashed, degreased and decolorized, enzymatic starch removal and beta-glucan extraction are simultaneously carried out, accordingly, the problem of difficulty in extracting oat beta-glucan coated in starch granules can be effectively solved, technologies can be simplified, and the cost can be reduced; isoelectric-point protein removal and enzymatic protein removal are combined with each other, and accordingly the protein contents of products can be reduced and reach 4.76%; the final ethanol concentration of ethanol precipitation systemsis 50%, polysaccharides with the molecular weights lighter than 5000 Da can be flocculated under the effective control of the ethanol concentration, and accordingly the purity of the oat beta-glucanproducts can be improved.

Description

technical field

[0001] The invention relates to the technical field of refining and processing plant active ingredients, in particular to a method for extracting β-glucan from oat and oatmeal processing by-products. Background technique

[0002] β-glucan is a non-starch polysaccharide present in oat endosperm and aleurone layer cell wall, which is composed of uniform D-glucopyranose units through β-(1,3) and β-(1,4) glycosides It is a kind of high molecular polymer, which is a linear macromolecule connected by bonds. β-glucan has many physiological functions such as improving the human immune system, regulating blood sugar, and maintaining the intestinal microbial environment. As a water-soluble active polysaccharide, oat β-glucan also has good water solubility, emulsification, and viscous Therefore, it can be used as a thickener, food functional factor, stabilizer, etc. in the food industry. In the beauty and skin care industry, because of its anti-aging, anti-radiation a...
