Uric acid-reducing ceramic membrane ultrafiltration technique for small-molecule active peptide of sunflower discs

Abstract

The invention relates to a uric acid-reducing ceramic membrane ultrafiltration technique for the small-molecule active peptide of sunflower discs, which includes: raw material pre-grinding, dynamic extraction of pulp; gradient enzymolysis by complex enzymes (the adding amounts of the enzymes are based on the raw materials); membrane separation; double-effect vacuum energy-saving concentration; high-speed centrifugal spray drying; and finished product packaging: hermitical packaging is adopted. The technique utilizes the gradient enzymolysis by the complex enzymes to extract small-molecule active substances. The small-molecule active substances with high additional value in sunflower disc resource are sufficiently exploited to fill up the research gap in the field.

Description

technical field [0001] The invention belongs to a method for extracting peptides or proteins, and in particular relates to a method for extracting small-molecule active substances from sunflower disks by using biological enzymatic hydrolysis technology. Background technique [0002] Sunflower dish, that is, the sunflower dish after removing the sunflower seeds, is rich in nutrients, containing 7%-9% of crude protein, 6.5%-10.5% of crude fat, 15%-18% of crude fiber, and 2.4%-3% of pectin. Nitrogen-free extract (mainly starch) is about 40%, and the content of crude protein and nitrogen-free extract can be comparable to that of grain. According to the analysis of Jilin Agricultural University, the total amino acid and essential amino acid content of sunflower disc are 7.96% and 3.7%, respectively, and It also contains more glutamic acid and glycine. [0003] Sunflower dishes are rich in various nutrients, but their utilization rate is low, and they are mainly used for pig feed...
