Description

Technical Field

[0001] The invention relates to the technical field of rice processing, in particular to a method for processing nutritious rice. Background Art

[0002] Rice is the largest grain in my country. Chinese people take rice as their staple food. It is delicious and never tires of eating it. It is accepted by almost 100% of the people. Rice products have unique aromatic flavor and are easy to digest. Therefore, rice and its products have the widest consumer base, huge development potential and a broad market. Research and development of rice has great social and economic benefits. Its processing methods are constantly developing with the improvement of people's living standards.

[0003] Brown rice is whitened, and the cortex and germ are removed. Refined edible rice, especially with the improvement of processing precision, is ground to the depth of the aleurone layer and subaleurone layer, and even to the outer endosperm and endosperm cell tissue. Its nutrient components are mainly starch, followed by less than 7% protein by mass, and as for vitamins, minerals, fats, dietary fiber, etc., they are very small.

[0004] Due to mechanized continuous production, the husk contains cellulose, hemicellulose, certain proteins, fats, vitamins and more inorganic salts, which are all lost during the rice polishing process. The endosperm is between the husk and the endosperm, containing more phosphorus, rich B group and inorganic salts, and the nutritional content of polished rice is greatly reduced. The rice processing precision is negatively correlated with the nutrient content. The higher the rice processing precision, the less husk and embryo are retained, and the greater the nutrient loss. Various bioactive ingredients in brown rice are almost lost during the whitening process of refined rice.

[0005] Therefore, the present invention aims to provide a processing method that can retain the nutritional components of rice. The nutritious rice that integrates traditional Chinese medicine theory and modern food processing technology effectively retains the rich vitamins, minerals, dietary fiber and other nutritional components in the rice through the treatment of specific temperature and time while ensuring the taste and quality of the rice. In addition, the present invention adopts ultraviolet wave radiation to further enhance the nutritional value of rice, enhance its biologically active components, and make the nutritious rice more competitive in the market.
