Rice protein powder is extracted from rice. It is yellow-white powder with no peculiar smell and is easily soluble in water. It is mainly composed of four proteins: albumin, globulin, gliadin, and gluten. The amino acid composition of rice protein powder is reasonable, and the amino acid content is high, which is recognized as edible protein. Due to its high nutritional value and hypoallergenic characteristics, it is used in infant food and functional food.
The main ingredient in rice is starch, which accounts for about 80-90%, and can provide a source of energy in the diet.
In addition to starch, rice is quite rich in nutritional value, containing fat-soluble vitamin E, unsaturated fatty acids, water-soluble vitamin B group, dietary fiber, and various minerals; and protein content can account for 5~8%, It is more than that in ordinary dairy products. (Dairy nutrients account for about 85% moisture and about 3.5% protein).
Further, if analyzed by Protein Efficiency Ratio (PER), rice has a score of about 2.3, which is an excellent protein with a PER score greater than 2.0 by definition.
In addition, when evaluating the integrity of the protein, it will analyze whether the 9 essential amino acids (Essential Amino Acid; EAA) contained in the protein are sufficient.
Nutritional supplements for fitness
As for the content of BCAA branched-chain amino acids that people who exercise or need nutritional supplements are very concerned about? Whey protein contains about 21%, soy protein contains about 17%, and rice protein is about 18%; the difference in content is not big , and a 2013 study published in Nutrition Journal told us that supplementing plant-based rice protein and animal-based whey protein after resistance training can help build and repair muscles, both of which There was no difference in achievable improvements in body composition and athletic performance.
Therefore, rice protein can also become a new choice for fitness friends. In addition, compared with whey protein and soy protein, rice protein has the advantage of being hypoallergenic and does not contain lactose. For people with allergies, lactose intolerance, or It is a more suitable choice for vegetarians.
Rice protein can be directly used as a nutritional supplement, brewed directly or added to soy milk to drink; it is also used in many foods, such as bread and biscuits, cereal brewing packs, plant double protein drinks, and instant porridge. , rice thin and noodles and other foods to increase the intake of good protein.
In recent years, due to the advancement of processing and extraction technology, functional peptide chains can be extracted from rice protein. In some cell and animal experiments, it has been found that it has the effect of lowering blood pressure or anti-inflammatory. In the future biomedical field, rice protein will have the potential to develop into health functional food or to manufacture medical preparations. In addition, choosing rice protein from plant sources can also help reduce carbon emissions and contribute to the earth.
