Embodiment 1

[0029] ①. The silkworm chrysalis weighed 500kg and washed with water, then crushed and refined silkworm chrysalis material with 1 to 8 to 10 times of water;

[0030] ②. Sterilizing and denaturing the silkworm chrysalis feed liquid after ① refinement, 120°C-130°C, 3-6 seconds for instantaneous treatment;

[0031] ③, lowering the temperature of the silkworm chrysalis feed liquid treated by ② sterilization and protein denaturation, and the temperature is reduced to between 54°C and 56°C;

[0032] ④. Add 2kg of compound protease to the material liquid after cooling down in ③, stir slowly, and keep the temperature between 54°C and 56°C. The process does not need to adjust the pH value;

[0033] ⑤. Centrifuge the feed liquid after the enzymatic hydrolysis in step ④ to remove insoluble matter, and obtain the non-digestible silkworm chrysalis protein feed liquid;

[0034] ⑥. Sterilize and deenzyme the step ⑤. The temperature of the feed liquid reaches 90°C-95°C through the sterilize...

Abstract

The invention discloses a method for preparing digestion-free silkworm chrysalis protein by using silkworm chrysalis as a raw material, belongs to biological food, and aims at producing a digestion-free silkworm chrysalis protein product by using silkworm chrysalis as a raw material and completing protein digestion in a human body in vitro through a biological enzymolysis technology. The digestion-free protein refers to micromolecular protein with the molecular weight of 500 Da (Dalton), wherein the micromolecular protein comprises compound amino acid with the average molecular weight of 120 Da and micromolecular dipeptide and tripeptide with the molecular weight of 180-500 Da. The protein of the sea cucumber is better high-quality protein, but the better protein can be absorbed by a human body only after being digested by the human body to be in an absorbable state. Due to the fact that all functions of the body of the old people are aged and declined along with the increase of the age, especially the digestive function, the utilization rate of protein is reduced due to insufficient digestion of the protein, a lot of protein resources are lost and wasted, and development of digestion-free protein products has great significance in supplementing protein nutrition for the old people.

Description

technical field [0001] The invention relates to a preparation method of biological food, in particular to a method for preparing non-digestion silkworm chrysalis protein by using silkworm chrysalis as raw material. Background technique [0002] According to the latest life theory and physiology, the growth period of the human body is around the age of 25, and the maturity period is over at the age of 30. The various functions of the body will begin to decline, and the functions will decline a lot after the age of 60. The new theory proposes that the main reason for the aging of the elderly is that the endogenous cell proteins shed in the intestine cannot be completely recycled, and the long-term protein deficiency in the body is the main reason for the premature aging of the elderly. Physiology points out that the longest life cycle of human intestinal cells is 43 hours, and the life cycle of gastric surface cells is three days. As new cells grow, old cells fall off. These c...
