Problems solved by technology

[0008] The purpose of this invention is to solve the problem of long-term body protein deficiency caused by insufficient recycling and utilization of cell protein in the body of the elderly due to aging of the body, and use biotechnology to produce non-digestible protein products with high branched chain amino acids to provide more valuable new products of biotechnology , to solve the protein imbalance problem of the elderly. The most important thing for human health is to balance nutrients and reduce body toxins. To produce protein products with high branched chain amino acids that do not need to be digested for the elderly has a huge effect on the health of the elderly.

Embodiment 1

[0025] 1. Corn gluten powder weighs 100kg;

[0026] 2. Use 8-10 times of water as the raw material of corn gluten to make slurry, and add 1000kg of water in this experiment;

[0027] 3. Ultra-high temperature sterilization and protein denaturation treatment are carried out on the feed liquid after mixing, and the temperature is at least 135°C for more than 50 seconds;

[0028] 4. Perform cooling treatment to reduce the temperature of the feed liquid to between 54°C and 56°C;

[0029] 5. Add 0.3%-0.5% compound protease by weight of raw materials for enzymolysis treatment. In this example, add 0.3 kg compound protease, and the enzymolysis time is 68 hours. The enzymolysis process does not need to adjust the pH value, but slow stirring is required;

[0030] 6. The enzymatic solution is separated by membrane to remove the unavoidably digested protein larger than 500 Da. After purification, the material solution is subjected to 90°C for 30 seconds to inactivate the enzyme or not t...

Abstract

The invention discloses a preparation method of a high-branched-chain amino acid digestion-free corn protein product. The digestion-free corn protein product with the branched-chain amino acid contentabout 22.24% is obtained by performing biological enzymolysis treatment on corn protein powder serving as a raw material. The digestion-free protein product refers to small-molecular protein with themolecular weight of 500 Da or below. The digestion-free corn protein product comprises compound amino acid with the average molecular weight of 120 Da and small-molecular dipeptide and tripeptide with the molecular weight of 180-500 Da. The protein does not need to be digested by a human body, and can directly enter the body through the small intestine of the human body to be absorbed and utilized. The protein product which can be absorbed without digestion is provided for the society, and after people are old, various functions of the body are degraded, digestive enzymes are reduced, the activity is reduced, the protein cannot be completely digested and absorbed, and protein is insufficient to cause aging.

Description

technical field [0001] The invention relates to food with protease deep processing technology, in particular, it converts macromolecular zein into non-digestible protein with a molecular weight below 500 Da and can be directly absorbed by the small intestine of human body through the shearing action of enzyme. Its components are compound amino acids with an average molecular weight of 125 daltons and small molecule dipeptides and tripeptides with an average molecular weight of 180 to 500 daltons. This section of protein does not need to be digested by the 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 the domestic peptide industry is determined by the content of dipeptides and tripeptides. The reason is that peptides greater than 500 Daltons are not directly absorbed by the human body, and products of this type of technology are basically not absorbed by the body after ingestion....
