Problems solved by technology

[0004] In addition, selenate and selenite are highly toxic inorganic salts, which will definitely cause harm to the human body to a certain extent in the process of large-scale production.
At the same time, selenate and selenite that have not been completely converted into organic selenium are still difficult to avoid remaining after treatment, which is not conducive to the production of fermented food

Abstract

The invention discloses a preparation method of food-grade selenium-enriched germinated rice, which belongs to the technical field of food processing. It is prepared according to the following steps: (1) Soak the pulverized selenium-enriched coal gangue in an acid solution and oscillate ultrasonically; (2) Precipitate and filter the solution obtained in step (1) for heavy metals; (3) Adjust the filtrate to neutral; (4) Brown rice is soaked in the filtrate at constant temperature and germinated; (5) Vacuum freeze-dried to obtain germinated rice with high selenium content. The method creatively uses selenium-enriched coal gangue as the raw material of selenium, replaces the use of inorganic selenite, effectively utilizes selenium-enriched coal gangue resources, improves the safety of the production process and germinated rice products, and the content of germinated rice The amount of selenium is as high as 220-260μg / Kg.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for preparing food-grade selenium-enriched germinated rice. Background technique [0002] Germinated rice, rich in nutrients, protein, fat, vitamin B1, and vitamin E are higher than white rice, and the phytate (IP-6) contained in it has a strong antioxidant capacity and helps to treat kidney stones , reduce cholesterol and blood lipids, and have anti-cancer effects; γ-aminobutyric acid (GABA) can improve cerebral blood flow, adjust blood pressure, calm nerves, etc., especially the germinated rice after the enzyme is fully activated, can lower blood pressure, stabilize nerves, Improve kidney and liver function, and inhibit cancer cells. Selenium can prevent and inhibit tumors, anti-aging, maintain the normal function of the cardiovascular system, and prevent the occurrence of arteriosclerosis and coronary heart disease. Selenium deficiency can lead to Keshan dis...
