Rana japonica oil polypeptide micro-capsule powder and preparation method thereof

Abstract

The invention discloses a rana japonica oil polypeptide micro-capsule powder and a preparation method thereof. The rana japonica oil polypeptide micro-capsule powder is prepared from the following components by weight percent: 10-20% of rana japonica oil polypeptide core material, 30-50% of maltodextrin, 10-20% of sodium carboxymethyl cellulose, 5-20% of beta-cyclodextrin and 5-10% of porous starch. The rana japonica oil polypeptide core material is prepared by treating a dry product of rana japonica oil in the following steps: selecting, soaking, performing colloid milling and performing enzymolysis by papain. The preparation method of the rana japonica oil polypeptide micro-capsule powder mainly comprises the following steps: 1, preparing a rana japonica oil polypeptide core material solution; 2, mixing solutions; 3, performing treatment of shearing emulsification; 4, performing spray drying and obtaining a finished product. In the preparation method disclosed by the invention, the rana japonica oil polypeptide micro-capsule powder is prepared by using a rana japonica oil polypeptide enzymolysis solution as a raw material and adopting a technology of low-temperature spray drying by appropriate wall material compatibility. The biological activity of polypeptide in the rana japonica oil enzymolysis solution is retained, and many performances of a product are improved. The rana japonica oil polypeptide micro-capsule powder not only can be preserved for a long time as a raw material for further processing, but also can be directly applied as a product, so that a new approach is provided for the deep processing of rana japonica.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a Rana oil polypeptide microcapsule powder and a preparation method thereof. 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 easier to be digested, absorbed...

AI Technical Summary

Problems solved by technology

[0003]However, the Rana oil polypeptide solution processed by enzymolysis still has the problems of high viscosity, difficult concentration, and difficult processing, and because the frog oil raw material itself is very precious, The purification of Rana oil polypeptide will cause a certain degree of waste of raw materials; Rana oil polypeptide itself has bitter and fishy smell, and is easy to oxidize and inconvenient to store. The Rana oil polypeptide powder obtained by direct milling has a large number of hydrophobic groups. Agglomerates, high water content, poor dispersion, easy to absorb moisture and agglomerate, and dissolve in water for a long time; however, there are few related studies on the microencapsulation of Rana oil peptides
