Problems solved by technology

[0011] The purpose of this invention is to solve the problem of long-term body protein deficiency caused by insufficient recycling of cell protein in the body due to the aging of the body of the elderly, and use bio-enzyme engineering technology to complete the digestion of protein in vitro, and provide protein that can pass through the small intestine without digestion. Absorbed protein products to solve the protein imbalance problem of the elderly, the most important substance for human health is protein, without protein there is no life

Embodiment 1

[0030] ①. Weigh 500kg of walnut cake, mix it with water whose weight is 1 to 7 to 8 times, and use a colloid mill to pulverize and refine it once;

[0031] ②. Sterilize and denature the walnut protein material liquid after ① refinement, 120°C-130°C, 10-15 seconds for instantaneous treatment;

[0032] ③. The walnut protein material liquid treated with ② sterilization and protein denaturation requires rapid temperature reduction treatment, and the temperature is lowered to between 54°C and 56°C;

[0033] ④. Add 2kg (0.3%-0.5%) compound protease to the material liquid after ③ cooling down, stir slowly, keep the temperature between 54°C-56°C, and the deep enzymatic hydrolysis time is 36 hours to 72 hours or longer Until the product standard is reached, the entire enzymatic hydrolysis process does not need to adjust the pH value;

[0034] ⑤. Centrifuge the feed liquid after the enzymatic hydrolysis in step ④ to remove insoluble matter;

[0035] ⑥. Sterilize and deenzyme the step ...

Abstract

The invention discloses a method for preparing digestion-free walnut protein by taking walnut cake meal as a raw material, belongs to biological food, and aims at producing a digestion-free protein product by using the walnut cake meal as the raw material and completing the digestion of protein in a human body through a biological enzymolysis technology in vitro. The digestion-free protein refers to small-molecular protein with the molecular weight of 500Da (Dalton) or below, and comprises compound amino acid with the average molecular weight of 120Da and small-molecular dipeptide and tripeptide with the molecular weight of 180-500Da. Proteins of walnuts are high-quality proteins; and all the proteins can be absorbed and utilized by the human body only after being digested to be absorbed by the human body. 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, particularly, the utilization rate of protein is reduced due to the digestion function and insufficient protein digestion; a large number of protein resources are lost and wasted; and development of digestion-free protein products has great significance in supplementing protein nutrition deficiency for the old people.

Description

technical field [0001] The invention relates to a method for preparing biological food, in particular to a method for preparing non-digestible walnut protein using walnut cake as raw material. Background technique [0002] According to the latest life theory and physiology, the human body is in the growth period before the age of 25, and the growth and maturity period is from the age of 25 to 30. After the age of 30, the functions of the body will start to decline, and after the age of 60, the functions will decline a lot. The new theory proposes that the main reason for the aging of the elderly is that endogenous cell proteins cannot be fully 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 cells are digested and uti...
