Rice protein powder has excellent nutritional quality and is recognized as a high-quality plant protein in cereal protein. According to the osmosis classification method, rice proteins can be roughly divided into 4 categories: protein, water-soluble protein, which accounts for 2% -5% of total protein; globulin, which is soluble in 0.5mol / L sodium chloride solution, which accounts for 2% -10%; gluten, soluble in dilute acid or base, accounting for more than 80% of total protein; gliadin, soluble in 70% -80% ethanol solution, accounting for 1% -5% of the total.

The research on rice protein powder has deeper significance

Among them, gluten and prolamin become storage proteins, which are the main components of rice protein powder. Albumin and globulin are relatively low in content and are physiologically active proteins in rice. Rice protein has high lysine content, essential amino acid content, high biological value and protein utilization rate, and has good nutritional value.

Our country is a big rice producing country and has abundant rice resources. Rice protein powder, as a routine production raw material in the rice deep processing industry, has been ignored for a long time. In recent years, due to in-depth research on it, it can make up for the defects of animal protein and prevent excessive intake of animal fat and cholesterol, which is favored by the food industry.

The rice protein powder industry has a broad market space. More importantly, further research and utilization of high-quality rice protein resources are conducive to the comprehensive utilization of rice deep processing, increasing the added value of rice, the development of technology-supported rice deep processing industry, and promoting the development of China's grain industry.
