Embodiment Construction

[0016] Below in conjunction with specific embodiment the present invention will be further described,

[0017] The germination is accelerated under the environmental conditions suitable for the growth of the wheat grains, that is, the relative humidity is 95% and the temperature is 24°C. The wheat grains were soaked in the prepared 300mg / L solution for 8h, and the degree of soaking reached 42%. The ratio of the solution to the weight of the wheat grains was 1:1.1.

[0018] Put the soaked wheat grains in a special germination machine to avoid light to germinate, and spray the wheat grains with 50mg / L sodium selenate solution at the same time, spray once every 20 minutes, each time for 30 seconds, and observe the germination situation. Ozone is introduced during germination;

[0019] After the sprouts reach a length of 3cm, they are rinsed with clean water at 25°C to obtain selenium-enriched wet malt;

[0020] The selenium-enriched wet malt prepared above is sterilized with oz...

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...
