Protein is an indispensable substance in human life activities. The various tissues and organs of the human body (such as the skin, muscles, bones, blood, internal organs, brain, etc.) are mainly composed of proteins; the metabolism of the human body and the loss of various tissues require proteins.
The calories required for life activities are also partly derived from proteins; Insufficient intake, although it will affect the life activities of normal people excessive protein intake or poor protein quality may also cause harm to the body. If animal protein is ingested, it will also bring in the corresponding cholesterol, so a healthy consumer concept advocates increasing the proportion of plant protein intake.
Common plant proteins are soy protein, pea protein and the like. In recent years, it has become more and more popular. Its promotion has expanded to food fortification, foods such as babies and children, as well as other special foods, cosmetics, etc., and constantly provide rice products with different specifications and functions.
The composition and function of rice protein.
Rice protein is mainly composed of four proteins: albumin, globulin, prolamin, and gluten. Rice residue is mainly endosperm protein, which is composed of albumin (4%-9%) and salt-soluble globulin (10%-11%), alcohol-soluble gluten (3%) and alkali-soluble gluten (66%-78%). Rice protein has high bio-price and high nutritional value, comparable to eggs, milk, and beef. In cereal proteins, protein prices (B.V.) and protein prices (P.V.) of rice proteins are higher than other proteins. The amino acid composition of rice protein has a reasonable balance and high amino acid content, which is unmatched by other plant proteins.
In addition, rice protein is a low-antigenic protein with better quality than wheat protein and zein, contains high-quality lysine, and has low sensitization, making rice protein very suitable for the development of baby food. Scientists have found that the amino acid composition, palatability and anti-allergic properties of rice protein are so superior that some scholars call it “the most famous plant protein in nature.” Rice protein not only has unique nutrition and health functions but also has anti-cancer effects. Recent studies have shown that rice protein can lower serum cholesterol levels.
Rice protein development.
As technology advances, rice proteins can also come from many species. Rice protein powder is one of them, and its nutritional and health functions are comparable to rice protein. The rice protein powder refers to a powdery substance formed of rice, which is processed by pulverization, purification, drying, and the like. Nutrients include proteins, vitamins, and cellulose. According to its protein content and solubility, it can be divided into feed grade rice protein powder, food grade rice protein powder and rice protein peptide. As the world’s largest rice producer, China has abundant rice protein resources. In recent years, due to the wide application of biotechnology, the production level of rice protein has been able to meet its market competition and obtain quality and cost advantages. “Made in China” food grade rice protein powder has a considerable market share in developed countries and regions such as the United States, the European Union, and Japan.
