Technical Field

The invention relates to a food of a protein enzyme deep processing technology, in particular to a digestion-free protein which can be directly absorbed by the small intestine of a human body with the molecular weight below 500Da and is converted from macromolecular soybean protein through the shearing action of enzyme. The components of the polypeptide are composite amino acid with average molecular weight of 125 Dalton, small molecular dipeptide and tripeptide with average molecular weight of 180 to 500 Dalton. The protein segment does not need to be digested by human body, and can directly enter the body through the small intestine of the human body to be absorbed and utilized. The quality of products in domestic peptide industry is good and bad, which means that the content of dipeptide and tripeptide is determined, because the peptides with the length of more than 500 daltons are not directly absorbed and utilized by human bodies, and the products of the process are basically not digested for the second time after being eaten by human bodies and cannot be utilized.

Background

According to the latest theories of life: it is considered that one of the main causes of aging in the elderly is insufficient recovery and utilization of endogenous cellular proteins, and long-term shortage of a nitrogen source in the body is a main cause of aging. The theory considers that the life cycle of human intestinal cells is only 2 days at most, the life cycle of gastric surface cells is three days, the old cells are shed as new cells grow out, the cells are digested and utilized by the human body like food, and normal people have 8-inch two, namely 248.8 g of intestinal cell protein shed every day. Half a kilogram of optimal human body cell protein with the biological potency of 100 does not consider the desquamated cell protein of the stomach, the cell protein of the intestine is not entwined by gastric acid denaturation treatment molecules, is very tight and is not easy to digest, and the normal young people can completely recycle the protein after the long-time digestion at the lower end of the small intestine. The old people can not completely recycle endogenous cell protein due to the decline of all functions of the aged organism, especially the reduction of the amount and activity of digestive enzymes, so that the long-term nitrogen source of the organism is unbalanced. It is clear what the body's long-term protein deficiency is as a result, why old people lose muscle so badly that the body cells use their own muscle proteins for survival. The body is in a state of vicious circle due to lack of nitrogen source and protein, the old has no way, the digestive function of the body is reduced, the digestive function is large, and the protein which is eaten by people is not digested, and the protein is not absorbed and utilized. In addition, the protein is not digested and fermented in the intestinal tract to generate a plurality of toxins such as skatole and the like, and the burden of the kidney is increased. It is known that the reason is that smelly fart is caused when people eat more meat, and the digestion-free protein product is the only method for solving the problem of protein deficiency of the old.

Indigestible proteins are proteins with a molecular weight below 500 daltons. Wherein the compound amino acid has an average molecular weight of 125Da and the small molecular dipeptide and tripeptide have molecular weights of 180-500 Da. Scientists have discovered during the study of genes that the human body has a substance that determines all functional activities of the human body's life, called peptides. He speaks: peptide is a revolutionary product that will lead the human nutritional revolution in the 21 st century. The human has been undergoing three health revolution since history, the first smallpox appeared, the solution was the vaccinium nikoense, the second penicillin was used to treat the disease caused by bacteria and virus, the third was the use of small molecule active peptide to treat all diseases including all major diseases, which was the problem of cell failure. Medical science states that only one disease of humans is cellular failure. Cell failure is due to 2 causes, 1, the cells are not nourished. (not getting the needed things) 2, cytotoxic overload. (get something not needed) if someone poisons your food and supplies, what happens.

Scientists have found a substance capable of prolonging life and have experimented with in mice, which was successful for the first time, the magical substance was a mixture of 3 amino acids leucine, isoleucine and valine, known by the scientific name "branched chain amino acids". In the experimental process, researchers add the 3 amino acids into water drunk by the tested mice, and as a result, the lives of the 3 amino acids are prolonged by 12%, and a series of positive biological reactions occur in the bodies of the mice while the lives of the 3 amino acids are prolonged, for example, cells can absorb more energy, free radicals are reduced, and the like, the free radicals are harmful compounds generated in oxidation reactions of the bodies, have strong oxidizing property, can damage tissues and cells of the bodies, and further cause chronic diseases and aging reactions. Through these in vivo changes, the mice appear to be fully active and have improved muscle coordination. Researchers have described that "branched chain amino acids" are an important and effective nutritional supplement that helps the organism strengthen muscles or gain more energy naturally without any side effects. The researchers in this project, professor Enzunesi of Milan university, Italy, indicate that amino acid nutritional supplements are invented on this basis, and then the amino acid nutritional supplements can benefit human beings in the future and have great help for the health of the old or patients.

The technology is a digestion-free protein product produced by using isolated soy protein as a raw material through an enzyme technology, wherein the compound amino acid contains branched chain amino acid, the branched chain amino acid consists of leucine, valine and isoleucine, and the isolated soy protein contains the following components in percentage by weight: 6.7266%, 4.0198% and 3.6899% in total, 14.4363%. The branched chain amino acid, so the development of the product has great significance to health.
