Problems solved by technology

[0003] However, the enzymatically processed Rana oil polypeptide solution still has the problems of high viscosity, difficulty in concentration, and difficulty in processing, and because the raw material of frog oil itself is very precious, the purification of Rana oil polypeptide will cause a certain degree of waste of raw materials; However, the Rana oil polypeptide itself has a

Abstract

The invention discloses a preparation method of forest frog oil polypeptide microencapsulation. The preparation method comprises the main steps of carrying out controllable enzymatic hydrolysis on forest frog oil to obtain a polypeptide core material solution, slowly adding a wall material under the mixing condition (wherein the wall material is prepared from the following components in percentage by weight: 1-10 percent of concentrated whey powder, 1-10 percent of maltodextrin and 0.5-5 percent of beta-cyclodextrine), adding 0.1-1 percent of monoglyceride, carrying out high-speed shearing and homogenizing treatment to obtain an emulsified feed liquid, and carrying out low-temperature spray drying treatment to obtain forest frog oil polypeptide microcapsule powder. With the adoption of the forest frog oil polypeptide microencapsulation, the content of a forest frog oil polypeptide core material is above 10 percent, the embedding rate is above 60 percent, the powder collection rate is above 53 percent, and the sensory property of the forest frog oil polypeptide microencapsulation powder is good without fishy smell; compared with core material spray drying powder without microencapsulation, the forest frog oil polypeptide microencapsulation powder has the advantages that the moisture content is lowered by above 30 percent, the solubility is increased by 3.5 percent, the hygroscopicity is lowered by 22 percent, and the dispersion time is shortened by above 30 percent. The preparation method has the characteristics that by virtue of the microencapsulation method, the fishy smell of a forest frog oil polypeptide product is removed effectively, the raw material waste is avoided, the operation is simplified and industrial production can be promoted.

Description

technical field [0001] The invention relates to a preparation method of Rana oil polypeptide microencapsulation, and relates to the fields of microcapsule technology and food processing technology. Background technique [0002] Rana oil is the dried fallopian tube of the female Rana, and it is a precious nourishing health product, which has the functions of nourishing the kidney and essence, moistening the lungs and nourishing yin. It is rich in protein, 18 kinds of amino acids, a variety of trace elements and vitamins, especially three sex hormones, namely estradiol, testosterone and progesterone. Rana oil enzymatic hydrolysis solution is to hydrolyze Rana oil through controllable enzyme engineering technology, decompose protein into polypeptides, improve the fluidity and solubility of Rana oil, reduce viscosity, and improve the processing of its industrial production Performance; due to the increase in the content of peptides and amino acids after enzymolysis, it is easie...
