Rice Protein Peptide

Release time:2022-07-24Author:admin
Rice peptide is a kind of protein hydrolyzate obtained by the action of protease and special processing of rice protein concentrate. It mainly contains mixed components of peptide molecules and a small amount of free amino acids, sugars, water and inorganic salts.

Rice protein is the top grade of grain protein, with high nutritional value, easy digestion and absorption, and reasonable amino acid ratio, which meets the needs of the human body. Especially the rice protein extracted from rice bran has an amino acid ratio closer to the FAO/WHO recommended model.

The rice peptide obtained from rice protein inherits a series of advantages of rice protein, but also has its unique functional advantages.

Rice peptides contain various amino acids needed by the human body, and the ratio is reasonable, especially the rice peptides obtained from rice bran, the essential amino acids are more suitable for the needs of children aged 2-5, and there are few allergic reactions. In addition, rice peptides are more easily digested and absorbed by the human body than amino acids or proteins, which is beneficial to infants with incomplete gastric digestion function, so it is considered as an ideal raw material for infant food and can be added to infant formula milk powder, rice flour middle.

The solubility of the rice peptide hydrolyzate obtained by the enzyme treatment is significantly improved than that of the rice protein solution, and the emulsification ability and emulsification stability of the rice peptide are also increased due to moderate hydrolysis and deamination. This expands its range of applications in food, for beverages, spreads, coffee mates, frothed cake toppings, sauces, baked goods, fillings, marinades, meats, flavours, candied fruit and Nutritional supplement for soft drinks and fruit juices.

Glutamate in protein itself is not a flavor enhancer, but glutamate in some peptides has flavor-enhancing properties. Rice protein is high in aspartic acid and glutamic acid, and its deamidated peptides and protein hydrolyzates can be used as food flavor enhancers for meat products, ready-to-eat rice, soups, sauces, gravies, and among other delicious foods.

Rice peptides have a certain surface activity, which shows good foaming ability, good control of hydrolysis rate, and the best foaming performance. Accordingly, it can be used to develop rice peptide foaming powder.

Rice peptides also have certain medicinal and health value. It has the effect of inhibiting ACE and reducing high blood pressure. In addition, rice peptide also has the functions of preventing, curing and regulating human physiological functions. It has been approved by the Ministry of Health of China as a food with immune regulation function.

With more and more in-depth research on the nutritional, physiological and other functions of rice peptides, rice peptides will be more widely and more scientifically used in the food industry and the pharmaceutical industry, thereby further promoting the comprehensive utilization and depth of rice resources. development.
