Embodiment 1

[0040] Take fresh Chinese giant salamander and add 700L of water for grinding, then add two to four times the volume of petroleum ether for degreasing, let stand for 20 to 30 minutes to remove the upper petroleum ether solution, keep the lower solution at 25°C for 60 minutes, and filter it once with three layers of gauze , the mesh screen is a 100-mesh microfiltration machine for microfiltration once, and 740L giant salamander filtrate I and 50kg filter residue I are obtained.

[0041] 100kg of mulberry leaves and 600L of water were stirred and extracted at a high temperature of 85°C for 120 minutes, filtered once with three layers of gauze, and micro-filtered once to obtain about 530L of mulberry leaf filtrate and mulberry leaf filter residue. The mulberry leaf filtrate was concentrated to dryness by a thin film evaporation concentrator. Get mulberry leaf extract.

[0042] Add 1600L of ethanol to the filtrate I, let it stand for 25min, and centrifuge at 7000rpm for 24min to o...

Embodiment 2

[0045] Take fresh Chinese giant salamander and add 900L of water for grinding, then add two to four times the volume of petroleum ether for degreasing, let stand for 20 to 30 minutes to remove the upper layer of petroleum ether solution, keep the lower layer solution at 30°C for 60 minutes, and filter it once with three layers of gauze , and the mesh screen is a 150-mesh microfiltration machine for microfiltration once to obtain 980L giant salamander filtrate I and 60kg filter residue I.

[0046] 150kg of mulberry leaves and 900L of water were stirred and extracted at 90°C for 100 minutes, filtered once with three layers of gauze, and micro-filtered once to obtain about 800L of mulberry leaf filtrate and mulberry leaf filter residue. The mulberry leaf filtrate was concentrated to dryness by a thin film evaporation concentrator. Get mulberry leaf extract. Add 2000L of ethanol to the filtrate I, let it stand for 25min, and centrifuge at 8000rpm for 25min to obtain 38.5kg of prec...

Abstract

The invention provides a giant salamander protein peptide powder product and a preparation method thereof. The preparation method comprises the following steps: carrying out water milling and alcohol precipitation, mixing the obtained precipitate with mulberry leaf filter residues, carrying out enzymatic hydrolysis to obtain a hydrolysate, carrying out thin film evaporation until the hydrolysate is dry, and mixing the dry hydrolysate with mulberry leaf extract to obtain the product. The product makes full use of proteins, polysaccharides and flavonoids in the giant salamander, overcomes the fishy smell produced by the giant salamander in traditional processes, and is very suitable for diabetic people to eat. The method can avoid the degradation of the polysaccharides under high temperature and acid and alkali treatment, can adjust the content of polysaccharides in the product according to different demands, and improves the yield of small peptides through the degeneration and hydrolysis of the proteins.

Description

technical field [0001] The invention relates to a giant salamander protein peptide powder product and a preparation method thereof, belonging to the technical field of food processing. Background technique [0002] The giant salamander is the largest amphibian in existence and belongs to the second-class national protected animal. It is widely distributed in my country, mainly in the mountain streams of the Yangtze River, the Yellow River and the upper and middle reaches of the Pearl River, especially in Sichuan, Hubei, Hunan, Guizhou, Shaanxi and other provinces. Giant salamander has high nutritional value, containing high-quality protein, rich amino acids and trace elements. Its body contains more than 50 kinds of natural bioactive substances. These bioactive substances have unique research and development value in food, medicine, cosmetics, health food, etc. It has been reported in the literature that the giant salamander oligoglycopeptide was prepared from the surface...
