Rice protein characteristics.
When it comes to the ingredients of rice, most people think that the ingredients of rice are starch. In fact, in every 100 grams of rice, the main chemical components of rice are starch and rice protein, which are about 80% and 8%, respectively. Rice protein is an ideal vegetable protein consisting mainly of four proteins: albumin, globulin, prolamin and gluten. In addition, rice also contains amino acids, trace elements, vitamins and other ingredients, and has a balanced amino acid composition, high nutritional value. Therefore, rice protein is a quality food protein.
What method is used to extract rice protein?
In industrial production, rice, brown rice and rice bran can be used to prepare rice protein, and there are many extraction methods such as alkali extraction, physical extraction and enzyme extraction.
- Alkali extraction refers to the degradation of rice protein under high alkali conditions, but it has a destructive effect on amino acids, and the protein yield is generally low.
- The physical method is mainly the use of physical means, such as ultrasound, ultra-high pressure, high-speed homogenization to change the primary structure of the protein or destroy its hydrogen bonds, so that the protein is more soluble, and there is no change in the dissolved protein. Current physical extraction is often used as an adjunct to increasing protein extraction rates.
- Enzymatic extraction is the hydrolysis of proteases in rice, the extraction of soluble short peptides and amino acids. Relatively speaking, the enzymatic extraction reaction conditions are mild, and the nutrients of rice are effectively preserved; the amino acid distribution of the hydrolysate is uniform, and the digestibility is high; the hydrolyzed product is safe, hygienic, soluble, and natural in taste. Its solubility, foamability and emulsifying properties are significantly improved. It can be said that enzymatic extraction is the best choice for rice protein extraction.
NEO FOOD uses advanced enzyme extraction technology to ensure that the rice protein powder is more delicate. Non-GMO and non-chemically contaminated rice is used as raw materials to ensure that rice protein powder is healthier.
