Is rice protein the best protein origin?

As one of the main grains widely grown around the world, rice not only provides energy, but also contains more than 90% of the nutrients needed by the human body.

With the continuous advancement of food science and technology, rice protein, which uses rice as raw material, is a rare high-quality plant-source protein, which is gradually recognized by people for its high nutrition and low antigenicity. have received widespread attention.

So, how much do you know about the miracle rice protein?

What is the rice protein

Rice protein is the protein extracted from rice, which is processed through crushing, purification, drying and other steps.

According to different processing raw materials, there are mainly two types of rice protein on the market at present, namely, rice protein made from broken rice in rice processing as the main raw material, and brown rice protein made from the first husked rice after rice processing. .?It is generally believed that brown rice protein has higher nutritional value and higher consumer acceptance.

According to a report issued by the World Food and Agriculture Organization (FAO), rice protein producers are currently mainly concentrated in China, the United States and New Zealand.

High biological value of rice protein

The data shows that the BV value (protein biological value) of rice protein is 77, the TD value (protein digestibility) is 82, and the PER value (protein utilization rate) is 1.7, which means that the amino acid composition of rice protein is balanced and reasonable, which is consistent with WHO/ The ideal model recommended by FAO is very close.

In addition, rice protein is rich in various amino acids such as methionine, lysine, isoleucine, and threonine. The biological value is also comparable to that of white fish, shrimp and beef.

Low antigenicity of rice protein

Many plant proteins contain anti-nutritional factors. For example, soybeans contain trypsin inhibitors, which are harmful to the body, and there are factors such as stachyose that cause flatulence. For newborns or those who are in poor health, All can cause allergic symptoms. Rice protein does not contain similar allergens, so it is safe and reliable.

In addition, rice protein has no pigment interference, hydrolysis does not produce bad flavors such as umami, salty, soft and not pungent, which is also an important feature that distinguishes it from other vegetable proteins.

Application of rice protein

1. Food additives

The water-soluble albumin component of rice protein accounts for only 2%-5% of the total, and the water-insoluble glutenin accounts for 75%-90% of the total.?Therefore, the solubility of rice protein is poor, and the stability and foaming properties The emulsification and emulsification properties are not outstanding, but this structural feature is convenient for proteolysis.?The hydrolyzed rice protein can thicken liquid, semi-solid food and even candy.

2. Nutritional supplements

With high nutrition and low antigenicity, rice protein has become the first choice of vegetable protein for special populations to supplement nutrition. Especially for sensitive diarrhea and celiac disease in infants and young children, rice protein can better supplement the body's ability and maintain nitrogen balance.

3. Development of functional peptides

Rice protein hydrolyzate contains a variety of small molecular peptides with physiological activity, which has certain medicinal and health care value, and has the functions of lowering blood pressure, anti-aging, lowering cholesterol content, and enhancing immunity.
