Problems solved by technology

[0007] In order to solve the problem of long-term body protein deficiency caused by insufficient recycling of cellular protein in the body due to the aging of the elderly, biotechnology is used to replace the old product of protein powder, and new products of more valuable biotechnology are provided to solve the protein problem of the elderly. The most important thing for human health is the balance of nutrients and the reduction of toxins in the body. The production of protein products that do not need to be digested for the elderly has a huge effect on the health of the elderly.

Embodiment 1

[0024] 1. Egg white liquid weighs 100kg;

[0025] 2. Add egg white liquid to 5 times of water to make slurry;

[0026] 3. Pasteurize the feed liquid after mixing, and keep the temperature at 62°C for more than 30 minutes;

[0027] 4. Perform cooling treatment to reduce the temperature of the feed liquid to between 54°C and 56°C;

[0028] 5. Add 0.3%-0.5% compound protease by weight of raw materials for enzymolysis treatment. In this example, add 0.3kg compound protease and enzymolysis time is 40 hours. The temperature of the enzymolysis process must be between 54°C-56°C There is no need to adjust the pH value, but slow stirring is required;

[0029] 6. Separating the enzymatic hydrolysis feed liquid through membrane to remove the unavoidably digestible protein larger than 500 Da, after purification, the feed liquid is subjected to an enzyme-inactivating treatment at 90°C for 30 seconds to obtain a high-purity enzyme-inactive non-digestible egg protein product;

example 2

[0035] 1. Egg white liquid weighs 200kg;

[0036] 2. Add egg white liquid to 6 times of water to make slurry;

[0037] 3. Carry out pasteurization treatment on the feed liquid after mixing, and keep the temperature at least 62°C for more than 30 minutes;

[0038] 4. Carry out cooling treatment, so that the temperature of the feed liquid is reduced to between 54°C and 56°C;

[0039] 5. Add 0.3%-0.5% compound protease by weight of raw materials for enzymolysis treatment. In this example, add 0.6 kg compound protease, and the enzymolysis time is 40 hours. The enzymolysis process does not need to adjust the pH value, but slow stirring is required;

[0040] 6. After the enzymolysis feed solution is purified by membrane separation or without membrane separation, it is subjected to an enzyme-inactivating treatment at 90°C for 30 seconds or an inactivating enzyme. Obtain high-purity and non-high-purity enzyme activity and inactive non-digestible egg protein feed liquid products with...

Abstract

The invention discloses a production method for producing digestion-free protein by taking various ovalbumin as raw materials. Digestion-free protein refers to small molecule protein with the molecular weight at 500 Da (Dalton) or below. The protein comprises the following components of compound amino acid with the average molecular weight of 120Da and small molecule dipeptide and tripeptide withthe average molecular weight of 180-500Da. The protein does not need to be digested by a human body and can directly enter the body through the small intestines of the human body to be absorbed and utilized. Whether the quality of the product in the domestic peptide industry is good or bad is determined by the content of dipeptide and tripeptide, because the peptide with the content of more than 500 Daltons is not directly absorbed and utilized by a human body, and the product of the process is basically not digested for the second time after being eaten by the human body. A high-purity digestion-free protein product can be produced by adopting a membrane separation technology on a production line, and a digestion-free protein product containing a small amount of peptides of more than 500Da can be produced without adopting a purification process.

Description

technical field [0001] The invention relates to a new food with protease deep processing technology. Specifically, it converts macromolecular protein into a non-digestible protein product with a molecular weight below 500 Da that can be directly absorbed by the small intestine of a human body through the shearing action of an enzyme. Its components are compound amino acids with an average molecular weight of 120Da and small molecule dipeptides and tripeptides with an average molecular weight of 180Da to 500Da. 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 larger than 500 Da are not directly absorbed and utilized by the human body, and products of this type of technology have a protective film that is bas...
