Embodiment 1

[0015] (1) Enzymatic hydrolysis: Using forest frog oil as the main raw material, the compound enzymatic hydrolysis method is used for controllable enzymatic hydrolysis. The obtained enzymatic hydrolysis solution is slightly yellow in color, slightly fishy, ​​slightly sour and bitter, and the degree of hydrolysis is about 40. %, the molecular weight of the hydrolyzed peptide is mainly distributed between 1000~7000 Daltons;

[0016] (2) Blending: Weigh 5-20% maltodextrin, 1-10% β-cyclodextrin, 5-20% whey protein powder WPI95, 1-20% concentrated whey protein powder WPC80, respectively, to clean In the drying container, slowly add to a certain quality of enzymolysis solution under the condition of sufficient stirring, and magnetically stir until it is completely dissolved;

[0017] (3) Preparation of emulsifier: Dissolve monoglyceride with a small amount of deionized water at room temperature, adjust it into a thin paste, heat in a water bath to 75℃-80℃, shake vigorously with a shak...

Abstract

A preparation method of oviductus ranae polypeptide specifically comprises steps: (1) enzymolysis, (2) blending, (3) preparation of an emulsifier, (4), high-speed shearing, and (5) freeze drying. In the method, freeze drying for powder preparation is adopted, and an oviductus ranae enzymatic hydrolysate is taken as a raw material. After dried oviductus ranae is made into the enzymatic hydrolysate, based on the enzymatic hydrolysate, oviductus ranae enzymatic hydrolysate powder low in hygroscopicity and good in resolvent performance is prepared through freeze drying and processes of reasonable blending and emulsification.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for preparing a wood frog oil polypeptide. Background technique [0002] Chinese forest frog (Ranachensinensis), also known as Hash toad, snow clam, etc., belongs to Amphibians, Anura, Ranaidae, and Rana. It is a unique species in my country. The main production areas are distributed in Northeast my country, especially in Jilin. In the 1930s and 1940s, Japanese scholars Kubota Haruhiko and Shoutian Bunjiro carried out basic analysis on the chemical composition of Rana oil, and the test results showed that: protein accounts for about 50% of Rana oil, and also contains a certain amount of fat, Carbohydrates, nitrogen, phosphorus, sulfur, etc. [0003] Rana oil has a variety of health functions such as improving immune function, anti-oxidation, anti-fatigue, and regulating blood lipids. Studies have shown that Rana oil enzymatic hydrolyzate also has similar health functions,...
