Organic selenium from aspergillus oryzae and method for preparing same

InactiveCN1632128AStrong selenium enrichment abilityGrow fastFungiFermentationFood additiveAspergillus wentii
The organic selenium derived from aspergillus oryzae and a preparation method thereof of the present invention belong to the field of food and health product additives. The organic selenium of the present invention uses Aspergillus oryzae as a carrier, and exists in the form of Aspergillus oryzae cells, aqueous solution or dry powder. Its preparation method uses selenium compound as raw material, through the process of preparing selenium-containing medium, inoculating and culturing Aspergillus oryzae, collecting Aspergillus oryzae, washing to remove extracellular selenium, sterilizing or/and drying; the organic aspergillus oryzae cell form is obtained by drying. Selenium, or the organic selenium in the form of an aqueous solution obtained from thalline autolysis, or the organic selenium in the form of dry powder obtained by drying the aqueous solution. Aspergillus oryzae has the characteristics of fast growth and high content of organic selenium in selenium-enriched Aspergillus oryzae cells. During the fermentation process, Aspergillus oryzae can convert inorganic selenium into organic selenium, which is easily metabolized and absorbed by the human body. Using Aspergillus oryzae containing organic selenium instead of common Aspergillus oryzae as an additive in food and health products can supplement selenium in a small amount and continuously, and effectively prevent and treat diseases caused by selenium deficiency.

Hydrogen-selenium rice

The invention provides hydrogen-selenium rice, composition of the hydrogen-selenium rice and a preparation method of the hydrogen-selenium rice. The hydrogen-selenium rice is composed of rice, and resistant starch, selenium-enriched yeast and ethylenediaminetetraacetic acid ferric sodium salt which can generate hydrogen gas in large intestines, so that the rice is named as the hydrogen-selenium rice. The hydrogen gas can be used for neutralizing free radicals in bodies. Selenium is a necessary microelement for human bodies and can be used for preventing and inhibiting tumors and resisting ageing; and China is a selenium-deficiency country so that a manner of enriching selenium in the rice is the best way for supplementing selenium. Iron deficiency anemia is one of nutrition deficiency diseases with the high morbidity in China; in estimation of Global Burden of Diseases in 2004, disability-adjusted life years (DALYs) caused by iron deficiency in every 100,000 people in China are 189 and rank 99th in 192 member countries; and the total loss of the whole country is 247.9 billion and ranks second last in the member countries. When people supplement iron through drugs, about 2000 yuan needs to be paid every year; 400-600 yuan needs to be paid when people eat health-care products to supplement iron; and the ideal effect can be realized by only spending additional 2-3 yuan when people eat iron-enriched rice.
