Preparation method of health-care germinated brown rice noodle

Abstract

The invention provides a preparation method of a health-care germinated brown rice noodle. The preparation method comprises the following specific steps: (1) selecting low-selenium brown rice which is full in grains and free from plant diseases and insect pests, cleaning and disinfecting the low-selenium brown rice, adding clear water to germinate rice grains, changing the clear water once every 8-15 hours, spin-drying the rice grains after buds come out and grow to a height of 0.5-1 mm, and conducting drying and crushing to 60-120 meshes; and (2) adding 200-300 parts of water into 100 parts of the obtained germinated brown rice flour, conducting grinding into thick liquid, adding 0.002-0.2 part of selenium-enriched yeast in a thick liquid grinding process or after the thick liquid grinding, and then carrying out cooking, cooling and extruding or pressing into strips to obtain the health-care germinated brown rice noodle, wherein in the step (2), the time from the beginning of adding the selenium-enriched yeast to the completion of cooking is not more than 30 minutes. The selenium-enriched yeast used in the method is convenient to purchase without limitation, and a selenium-enriched health-care germinated brown rice noodle product can be produced on the basis of the existing technology of the germinated brown rice noodle; the selenium content of the rice noodle can be adjusted in a very wide range of 0.04-1 mg/kg; and the rice noodle is smooth in surface, good in elasticity, rich in nutrition and capable of regulating intestines and stomach and reducing cholesterol.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of germinated brown rice health-care rice noodles. Background technique [0002] Paddy rice is the main grain variety of our people, and rice flour is a kind of main processed product of rice, is liked by the masses of people in South China, and wherein germinated brown rice flour is a more and more popular rice flour product. [0003] Rice noodles are usually strip or flake products made from rice as raw material through processes such as soaking, wet grinding, steaming, and layering. Brown rice flour is made from brown rice as the main raw material; germinated brown rice flour is first germinated and then further made into rice flour. Compared with ordinary polished white rice, the cortex and germ end of brown rice are removed, and the content of vitamins, minerals and dietary fiber is richer. It is a healthy food. [0004] During the ...

Problems solved by technology

[0008] The biotransformation of inorganic selenium into organic selenium in the germination process of brown rice is an effective, simple and selenium-enriching method worth promoting, but the process is difficult to control and master. Both are relatively slow, and the residual rate or concentration of inorganic selenium is often high, which is easy to cause poisoning due to excess, and the process of biological conversion of inorganic selenium into organic selenium is not easy to coordinate with the germination process of brown rice

Sodium selenite is still a highly toxic and controlled raw material, and there is a problem of licensing, which is difficult for general rice flour manufacturers to adopt
