Method for extracting small-molecular peptide from cubilose

Abstract

The invention discloses a method for extracting small-molecular peptide from cubilose. The method comprises the following steps: a, weighing complete cubilose, soaking with clear water for 30-50 minutes, and drying the soaked cubilose; b, grinding the dried cubilose in a grinder after the step is finished, and screening with a sieve of 100-230 meshes; c, performing wall-breaking on the screened powder with a high-speed blender to obtain fine powder after the step c is finished; and d, putting the fine powder into a mixer after the step c is finished, adding deionized water into the mixer for mixing, and sterilizing the mixed liquid into a sterilizing tank. According to the method, composition of xylanase, pectinase and papain is utilized for gradient enzymolysis, protein is subjected enzymolysis with the papain, and the extracted small molecular peptide has relatively high extraction rate and can be easily absorbed by a human body; and the operation process are simple and convenient insteps, each step can be easily controlled, and the processing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of small molecular peptides, in particular to a method for extracting small molecular peptides from bird's nests. Background technique [0002] Bird's nest, also known as swallow dish, swallow root and swallow vegetable, refers to the nest made of the saliva secreted by some swifts of the Swift family Swift family and several swiftlets of the genus Swiftlet, and then mixed with other materials. The nesting places can be divided into "house swallows" and "cave swallows". Cave swallows are divided into white swallows, yellow swallows, and red swallows because they are affected by minerals and cause different colors. Bird's nest is one of the traditional and precious foods that have been eaten in China since the Ming Dynasty. Modern medical research has found that the main components of bird's nest are: water-soluble protein, carbohydrates; Amino acids that play important roles (lysine, cystine and arginine), ...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing method for extracting small molecule peptides from bird's nest still has some shortcomings, for example; the existing method for extracting small molecule peptides from bird's nest generally only uses one or two kinds of enzymes to decompose, which reduces the concentration of small molecule peptides. The extraction rate weakens the effect of small molecular peptides being absorbed by the human body, and the existing method for extracting small molecular peptides from bird's nest is relatively complicated in operation and process steps, and it is difficult to control each link, which increases the processing cost and reduces the cost.
