1.Health function
Anti-hypertensive and cholesterol-lowering rice protein isolate affects the expression of cyp4a and cyp2c in the kidneys of young mice, which can improve arachidonic acid metabolism and can be used as an anti-hypertensive ingredient. Studies have found that rice protein isolate can increase the amount of messenger ribonucleic acids (mRNAs). RNAs are responsible for the synthesis of two important proteins in the kidney, cyp2c11 and cyp2c23. These two proteins play a significant role in the metabolism of arachidonic acid and hydroxyeicosatetraenoic acid. important role, and hydroxyeicosatetraenoic acid is important in regulating blood pressure. Clinical studies have found that rice protein isolate can lower cholesterol. Rice contains many chemicals related to its protein composition, including tocopherol derivatives, tocotrienols and oryzanol, which have a certain effect on lowering cholesterol.
Preventing Chronic Diseases Proper and nutritious diet can prevent some diseases, such as heart disease. Asians are less likely to suffer from heart disease than Europeans, which may be related to the fact that Asians eat rice as their staple food. Relevant studies have found that rice protein isolate has a certain inhibitory effect on atherosclerosis in a mouse model of hereditary hypercholesterolemia and can reduce the destructive effect of atherosclerosis on arteries. The mechanism of action is still unclear; experiments also show that eating rice can reduce the risk of atherosclerosis. Heart disease rates.

1. Rice protein bioactive peptides
Takahashi et al. isolated and purified an active peptide called oryzatensin from trypsin hydrolyzate of rice albumin. Its amino acid sequence is Gly–Tyr–Rro–Met–Tyr–Pro–Leu–Pro–Arg, which can cause ileum contraction in guinea pigs. Antimorphine and immunomodulatory activity. Rice protein contains a large number of hydrophobic amino acids. When enzymatically digested by a suitable protease at a specific site, a peptide fragment containing a hydrophobic amino acid at the C-terminus will be obtained, namely an active peptide fragment of ACE (angiotensin-converting enzyme angiotensin-converting enzyme). While ACE inhibitors are a major drug for the treatment of hypertension, rice proteolytic active peptides are highly safe and have no side effects.
2. Nutritional supplements
For infants with sensitive diarrhea, rice protein is widely used to develop high-protein, hypoallergenic infant formula rice noodles due to its low antigenicity and high nutritional value. Rice protein is gluten-free and suitable for people with wheat intolerance, allergies or celiac disease. Rice protein concentrate can also be used as a food supplement for patients with reduced normal protein intake or damaged protein digestion function to maintain nitrogen balance; it can also be used as an osmotic diuretic, peptic ulcer, and auxiliary treatment for trauma.
3. Food additives
Treating rice bran protein with enzymes has significantly improved its solubility, foaming, and emulsifying properties. In particular, endoproteases and exoproteases are used to moderately hydrolyze and deaminate rice bran proteins to obtain peptide chains with moderate length and function. Characteristic protein hydrolyzate can increase the solubility of rice bran protein and improve other functional properties. It can be used as food emulsifier, foaming agent and nutritional fortifier.
4. Edible film
The Southern Louisiana Research Center in the United States has developed an edible film with certain tensile strength and water vapor resistance using a combination of rice protein concentrate and pullulan, which can be used as a carrier for flavor substances and nutritional additives or for separation, protection and preservation. Isolator.
5. Rice protein feed
Rice starch by-products can be used as feed-grade rice protein powder. Its rich nutrients can help livestock and poultry resist disease and improve feed utilization. It is an excellent additive in the feed industry.

1.Solubility
The solubility of rice protein is not very good, mainly because rice protein contains more than 80% alkali-soluble gluten. These glutens are formed by many macromolecule fragments through disulfide bonds, cross-linked with each other and condensed, while albumin that is soluble in water It only accounts for 2% to 5% of rice protein. In the study of the effect of pH on the solubility of rice protein, it was found that when the pH value was 4 to 7, the solubility of gluten in rice protein increased slowly, while when the pH value was close to 9, the protein solubility increased rapidly. At the same time, modification will also have a certain impact on the solubility of rice protein. Research shows that the degree of deamidation is between 19.6% and 64.5%. As the degree of deamidation increases, the solubility of rice protein increases, and the solubility can reach 96.6%. Through comparative analysis of multiple proteases, it can be seen that the hydrolysis effect of alkaline protease is better than that of other proteases, but the orthogonal test results show that even under optimized conditions, the highest solubility of rice protein hydrolyzed by a single alkaline enzyme reaches 43.12% . If alkaline protease is first used for hydrolysis and then compound protease is used for hydrolysis, the protein solubility reaches a maximum of 71.46%, while the combined application of alkaline protease and other enzymes has a slightly poorer effect; if compound protease is used first and then alkaline enzyme is used, the protein solubility is only 71.46%. 54.73%. Therefore, different enzymes have different hydrolysis characteristics for rice protein molecules.

2. Emulsifying properties
Emulsification includes two aspects: emulsification activity and emulsification stability. Emulsification is one of the important functions of protein. Research shows that measures to increase the solubility of rice protein are beneficial to improving the emulsifying properties of rice protein.
Once gluten is dissolved, its emulsifying ability is comparable to that of soy protein. After RPI and E-RPI were treated with Na2SO3, the emulsification properties were significantly improved, indicating that the physical and chemical functionality of rice protein can be improved by depolymerizing subunits in rice protein molecules.

3. Foaming property
Research has found that modifying rice protein isolate using the alkaline protease Alcalase can significantly improve its foaming performance. After extracting rice protein with alkaline enzyme, when the pH is neutral, as the protein concentration increases, the foaming property increases and the foaming stability decreases; when the pH value is 6.8, that is, when the rice protein solution is close to neutral , rice protein has better foaming properties and foam stability, and the rice protein extracted by alkaline protease has better foam stability than the rice protein extracted by papain; while the rice protein extracted by the two enzymes has better foam stability under different pH conditions. There is not much difference in bubble properties. As the concentration increases, the foaming property and foaming stability of the rice protein extracted by the two enzymes gradually increase. Generally speaking, the foaming property and foaming stability of rice protein extracted by papain are better than that of rice protein extracted by alkaline protease.

4. Water-holding and oil-holding properties
The water-holding capacity of protein is closely related to the preservation of freshness and shape during food storage. In addition, it is related to the viscosity of the food, while the oil absorption is related to the protein type, source, processing method, temperature and the oil used. Due to the poor solubility of rice protein, its water-holding and oil-holding properties are limited. However, after deamidation modification, the water holding capacity and oil holding capacity of rice protein have improved. When the deamidation degree is 35.7%, the water holding capacity is the lowest and the oil holding capacity is the highest. When the deamidation degree is 42.4%, the water holding capacity and oil holding capacity are the highest. quite.

Rice protein is a recognized high-quality plant protein. People in my country whose staple food is rice can consume up to 300 g of rice per person per day, of which 20-30 g of rice protein can be consumed, accounting for more than 40% of the total daily protein intake. In addition, the amino acid ratio of rice protein is close to the optimal amino acid ratio recognized by the WHO. Its BV (biological value) and PER (protein utility ratio) can be said to be the best among plant proteins, comparable to animal proteins, and are The only grain protein that is exempt from allergy testing.

As a recognized hypoallergenic food, rice protein is also the first raw material to appear in infant food. Rice protein has also been shown to be feasible as a substitute for milk powder in children with cow's milk allergies. Although hydrolyzed cow's milk, soy protein, or other formulas may also protect against cow's milk allergic reactions, infants with cow's milk allergies are more tolerant to formulas containing rice protein. As a nutritional supplement, rice protein can replace casein, whey protein and soy protein in sports nutrition.

Active peptides with different functions can be isolated from the enzymatic hydrolyzate of rice protein, which have the effects of antioxidant, regulating immune activity or improving sleep disorders. At the same time, due to their high solubility, they can also be widely used in health care products and solid products. in drinks. In addition, the amino acids exposed by enzymatic hydrolysis impart a special umami taste, and moderately hydrolyzed flavor peptides can be used in seasonings.
