Abstract

The invention discloses a method for preparing high-peptide dietary fiber granules by enzymolysis of corn sugar residues, and belongs to the technical field of dietary fiber preparation. The method comprises the following steps: firstly, drying and crushing the corn starch sugar residues; adding a vegetable oil extraction solvent to extract oil, and removing fat in the starch sugar residues; adding alkaline protease to carry out enzymolysis on the protein, and collecting small molecular protein peptide through a micro-filtration membrane; adding cellulase for enzymolysis, and using a supercritical CO2 technology for purification; and finally performing drying granulation. According to the product produced by the method, high peptides are added on the basis of existing pure dietary fibers,corn byproducts are efficiently utilized, and the product treated by adopting the supercritical CO2 technology is strong in physiological activity.

Description

technical field [0001] The invention relates to the technical field of dietary fiber preparation, in particular to a method for preparing high-peptide dietary fiber granules by enzymolyzing corn sugar residue. Background technique [0002] Corn starch sugar residue is a by-product obtained after acid hydrolysis in the process of making sugar from corn, which contains a variety of nutrients: fat, protein, dietary fiber, etc. Our sugar enterprises produce more than 300,000 tons of sugar slag every year. At this stage, it is mainly used as raw material to produce protein feed, which has not been rationally and effectively utilized. At present, some enterprises use sugar residue to produce fuel ethanol, and some use it to burn electricity for power generation. These are all in the research and exploration stage. Only by developing high value-added products can they be conducive to sustainable development. [0003] Insoluble dietary fiber mainly includes cellulose, hemicellulose...
