Embodiment 1

[0035] Embodiment 1: (soft-shelled turtle small molecule polypeptide preparation 1)

[0036] Follow these steps:

[0037] (1) Raw material pretreatment: Select 400kg of fresh and live soft-shelled turtle raw materials, slaughter, remove the film, remove the viscera, chop, put into an ultra-low temperature pulverizer to cool down to -170°C and pulverize, then put it into the reaction kettle, and weigh the weight of fresh and live soft-shelled turtle raw materials (The raw material weight of following each step all refers to the weight of fresh and alive soft-shelled turtle) and water weight 1: 1 ratio adds water 400kg; Heat up to 80 DEG C and keep warm for half an hour and then cool down to 60 DEG C, set aside;

[0038] (2) Trypsin enzymolysis-boiling and heat preservation-compound enzymolysis treatment: Add 200 g of trypsin according to 0.05% of the weight of raw materials, adjust the pH value to 6.5-7.0 with 10% NaOH solution at a temperature of 55-60°C, and enzymolysis 4 ho...

Embodiment 2

[0044] Embodiment 2: (soft-shelled turtle small molecule polypeptide preparation 2)

[0045] In this example, the fresh and alive soft-shelled turtle raw material that step (1) selects is 400kg; Step (2) adds trypsin 300g by 0.075% of raw material weight, enzymolysis 2.5 hours; Adds compound protease 300g by 0.075% of raw material weight in addition, Enzymolysis for 2.5 hours; then add 24kg of perlite powder by 6% of the raw material weight; step (4) add 8kg of activated carbon by 2% of the raw material weight; Liquid 110kg; Step (6) adds 11kg of 95% edible alcohol by 10% of the concentrated solution weight, static precipitation 3 hours; Step (7) after ultrahigh temperature sterilization and spray drying, get white powdery soft-shelled turtle small molecular polypeptide finished product 34kg , and the yield is 8.5%; all the other steps and processes are the same as in Example 1.

Embodiment 3

[0046] Embodiment 3: (soft-shelled turtle small molecule polypeptide preparation 3)

[0047] In this example, the fresh and alive soft-shelled turtle raw material that step (1) selects is 400kg; Step (2) adds trypsin 400g by 0.1% of raw material weight, enzymolysis 1 hour; Adds compound protease 200g by 0.05% of raw material weight in addition, Enzymolysis for 4 hours; then add 16kg of perlite powder by 4% of the weight of the raw material; step (4) add 12kg of activated carbon by 3% of the weight of the raw material; Liquid 100kg; Step (6) adds 10kg of 95% edible alcohol by 10% of concentrated solution weight, static precipitation 4 hours; Step (7) gets white powdery soft-shelled turtle small molecule polypeptide finished product 36kg after ultra-high temperature sterilization and spray drying , and the yield was 9%; all the other steps and processes were the same as in Example 1.

Abstract

The invention discloses a method for preparing small molecular peptides of soft-shelled turtle, belonging to the field of health product production technology. The method comprises the steps: pretreatment of fresh and live soft-shelled turtle as raw material; digestion by pancreatic enzyme-boiling and heat preservation-digestion by complex enzyme; degreasing by means of high-speed separation; decolorization and fishy smell removal by activated carbon; vacuum concentration; alcoholic precipitation and impurity removal; and ultrahigh temperature sterilizing, spray drying and the like. The method has the characteristics of advanced technology, being safe and healthy and excellent quality and efficiency, and the yield of peptides of soft-shelled turtle reaches 8-9%, wherein the small molecular peptides with the molecular weight below 5000 Daltons accounts for over 95%, and the content of protein in the product which is purely white and powdery is not less than 90%, thus the product accords with microbial health indexes and is liable to be absorbed and utilized by intestines and skins of human. The method can be popularized and applied to the enterprises of health products and beauty / skin care products.

Description

technical field [0001] The invention relates to the technical field of production of nutrition and health care products, in particular to a method for producing small-molecule polypeptides of soft-shelled turtles using fresh and alive soft-shelled turtles. Background technique [0002] Soft-shelled turtle, also known as soft-shelled turtle and turtle, is a precious aquatic economic animal. The meat is fresh, tender and delicious, and rich in nutrition. Each kilogram of meat contains 165g of protein, 10g of fat, 16g of carbohydrates, 9g of ash, 1070mg of calcium, 1350mg of phosphorus, and iron 14mg, 6.2mg of thiamine, 3.7mg of riboflavin, 37mg of niacin, which have the effects of strengthening the body and prolonging life. In addition, soft-shelled turtles are also rich in Mg, Fe, Ca, Zn, Mn, and Se elements, which have the effects of nourishing blood, strengthening bones, improving intelligence, anti-fatigue, and anti-oxidation. Because soft-shelled turtle has high nutritio...
