Production method for high-conversion rate organic selenium malt yeast

Abstract

The invention provides a production method for high-conversion rate organic selenium malt yeast. The production method comprises the following steps: putting wheat grains in a sodium selenite solution with a temperature of about 25 DEG C and a concentration of 200 to 400 mg / L and carrying out seed soaking and spraying, wherein the length of wheat sprouts is controlled to be 1 to 5 cm; then carrying out sterilization through ozone and microwaves; carrying out crushing to obtain slurry; and adding yeast for conversion. According to the invention, since selenium-rich yeast is employed for secondary conversion, residual inorganic selenium in selenium malt is totally converted into organic selenium, so the produced high-conversion rate organic selenium malt yeast is safer and has better effect. In the process of production, waste water and selenate are not discharged; the production method is simple to operate and easy to control, does not pollute the environment and has low cost; and due to the low cost, the production method is expected to benefit more people.

Description

technical field [0001] The invention relates to the field of trace element organic selenium as a health food additive, that is, a production method of organic selenium malt yeast with high conversion rate. Background technique [0002] Everyone knows that selenium is an indispensable trace element for human beings. It can resist aging, prevent and inhibit tumors, maintain the normal function of the cardiovascular system, and prevent arteriosclerosis; although it is trace, it is very important, whether it is a healthy population or a disease All patients need selenium. The daily intake of organic selenium in about 2 / 3 areas of my country is less than 50 micrograms. These areas cannot obtain enough organic selenium from the earth itself, so it is imperative to artificially synthesize organic selenium with high conversion rate. However, inorganic selenium cannot be directly absorbed by the human body, and it is also a highly toxic substance. How to fully transform inorganic se...

Problems solved by technology

This liquid submerged fermentation method must have the steps of liquefaction and solid-liquid separation, and also requires the process of wastewater treatment. The result must be a lot of selenium loss, high energy consumption, serious pollution, and high cost.

This just causes the product that sells on the market to exist the problem of high cost and expensive price, has influenced the expanding use of product; Large, so the effect is poor, the existing production method needs to be improved
