Abstract

The invention provides a rice machining process. Selenium-rice rice is used as a raw material; and firstly, the selenium-rice rice is subjected to three-machine series rice milling to prepare husked rice, then the husked rice is subjected to two-machine series rice milling to obtain refined rice and an aleurone-embryo mixture, then the aleurone-embryo mixture is subjected to superfine grinding toprepare superfine powder with a particle size smaller than or equal to 10mum, the superfine powder is dispersed into basic aqueous solution to prepare pre-treating liquid, and finally, the refined rice is soaked in the pre-treating liquid to carry out vacuum freezing drying, so that films are formed on the surfaces of the refined rice to obtain the pre-treated refined rice, then the pre-treated refined rice is flushed by utilizing the basic aqueous solution, and natural air-drying is carried out. In the machining process of the rice machining process provided by the invention, after an aleurone layer and embryos, which are rich in nutrient substances, are prepared into the superfine powder, the superfine powder is recoated to the surfaces of the refined rice, and finally, the films are formed on the surfaces by utilizing the basic aqueous solution so as to effectively avoid loss and deterioration of the nutrient substances such as selenium, proteins and the like in the machining and storing process.

Description

technical field [0001] The invention relates to the technical field of agricultural product processing, in particular to a rice processing technology. Background technique [0002] Rice is one of the main food sources worldwide and is processed from paddy grain. From the outer layer to the inner layer of rice, there are cortex, aleurone layer, endosperm layer, and germ in sequence. Among them, the cortex and aleurone layer belong to the bran layer. When rice is milled, the bran layer and germ are removed to obtain polished white rice. The husk is mainly cellulose. and hemicellulose, the endosperm contains a lot of sugars, the germ contains extremely rich B vitamins, vitamin E and a large number of enzymes, the aleurone layer contains rich minerals and more protein, and the main components of rice are Sugars, of which starch accounts for about 75% of the weight of rice. The starch of japonica rice is composed of 17% amylose and 83% amylopectin. It is easier to digest after m...
