Application fields of rice protein
2024-05-21
1. Rice protein bioactive peptide
A oryzatensin active peptide was isolated and purified from the trypsin hydrolysate of rice albumin, whose amino acid sequence is Gly-Tyr-Rro-Met-Tyr-Pro-Leu-Pro-Arg, and has anti-morphine and immunomodulatory activities in the ileum of guinea pigs. Rice protein contains a large number of hydrophobic amino acids, through the appropriate protease in the specific site of enzymatic hydrolysis will be obtained containing C- terminal hydrophobic amino acid peptide fragments, namely ACE(angiotensin-converting angiotensin converting enzyme) active peptide fragments. ACE inhibitor is a major drug for the treatment of hypertension, and rice proteolytic active peptides are safe and have no side effects.
2. Nutritional supplements
For sensitive diarrhea in infants, rice protein is widely used to develop high-protein low-allergy infant formula rice noodles because of its low antigenicity and high nutrition. Rice protein is gluten-free and is suitable for people with wheat intolerance, allergies, or celiac disease. Rice protein concentrate can also be used as a normal protein intake to reduce or protein digestive function damage patients supplement food, maintain nitrogen balance; can also be used as osmotic pressure diuretics, digestive inflammation, trauma adjuvant therapy.
3. Food Additives
Enzyme treatment of rice bran protein, its solubility, foaming, emulsifying properties have been significantly improved, especially with endoprotease and exoprotease on rice bran protein moderate hydrolysis and deamination reaction, obtained with moderate peptide chain length and functional properties of protein hydrolysates, improve the solubility of rice bran protein, improve other functional properties, can be used as food emulsifier, foaming agent, nutrition fortifier.
4. Edible film
The Southern Louisiana Research Center used rice protein concentrate in combination with pullulan to develop an edible film with a certain tensile strength and resistance to water vapor, which is used as a carrier for flavor substances and nutritional additives or as a separator for separation, protection and preservation.
5. Rice protein feed
Rice starch by-products can be used as feed-grade rice protein powder, its rich nutrients have the function of promoting disease resistance to livestock and poultry, and can improve the utilization rate of feed, is an excellent additive in the feed industry.
6, Plant Based Products
Rice protein can quickly supplement the protein in the body. At the same time, it also has the characteristics of low sugar, low fat, zero cholesterol, no pigment and preservatives. It can regulate cholesterol metabolism, improve exercise indicators, enhance bone health, antioxidant, and many other aspects. It has outstanding performance, so it is widely used in plant-based products.
