Embodiment 1

[0028] 1. Weigh 100kg of soybean protein isolate and 15kg of coffee bean powder;

[0029] 2. The soybean protein isolate raw material is mixed with 9-10 times of water, and the coffee bean slurry after the dregs is added;

[0030] 3. Ultra-high temperature sterilization, passivation of physiologically harmful substances and protein denaturation treatment are carried out on the feed liquid after mixing, and the temperature is at least 135 ° C for more than 60 seconds;

[0031] 4. Perform cooling treatment to reduce the temperature of the feed liquid to between 54°C and 56°C;

[0032]5. Add 0.3%-0.5% compound protease by weight of raw materials for enzymolysis treatment. In this example, add 0.4 kg compound protease, and the enzymolysis time is 70 hours-75 hours. The enzymolysis process does not need to adjust the pH value, but slow stirring is required deal with;

[0033] 6. After the enzymolysis feed liquid is purified by fine filtration, the feed liquid is subjected to an e...

example 2

[0037] 1. Soybean high-temperature soybean meal weighing 200kg, coffee bean powder 17kg;

[0038] 2. The raw materials of soybean meal and coffee bean powder are slurried with 9-10 times of water and then pulverized, with a fineness greater than 100 mesh;

[0039] 3. Ultra-high temperature sterilization, passivation of physiologically harmful substances and protein denaturation treatment are carried out on the feed liquid after mixing, and the temperature is at least 135 ° C for more than 60 seconds;

[0040] 4. Perform cooling treatment to reduce the temperature of the feed liquid to between 54°C and 56°C;

[0041] 5. Add 0.3%-0.5% compound protease by weight of raw materials for enzymolysis treatment. Example 2: Add 0.8 kg compound protease, and the enzymolysis time is 70 hours-75 hours. The enzymolysis process does not need to adjust the pH value, but it needs to be slow Stirring treatment, centrifugation is required after enzymatic hydrolysis;

[0042] 6. Fine filter and...

Abstract

The invention discloses a preparation method of digestion-free coffee protein from soybean protein isolate or high-temperature and low-temperature soybean meal and coffee bean powder as raw materials, and belongs to the field of new biological food. A digestion-free coffee protein product is produced from the soybean protein isolate or the high-temperature and low-temperature soybean meal and coffee bean powder as raw materials through enzymolysis. The digestion-free protein refers to protein with the molecular weight of 500 Da, compound amino acid with the average molecular weight of 120 Da and micromolecular dipeptide and tripeptide with the molecular weight of 180-500 Da are provided, and the digestion-free protein product containing coffee is provided in the market.

Description

technical field [0001] The invention relates to a method for preparing food, in particular to a method for preparing coffee non-digestible protein. 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 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 utilized by the human body like food. Normal people There are 8 ounces of s...
