Problems solved by technology

However, ionic selenium dissolved in water is particularly easy to lose during the production process, resulting in low utilization rate and insignificant economic benefits
If you ingest high levels of ionic selenium for a long time, it will not only cause waste, but also cause selenium poisoning

Abstract

The invention specifically relates to a preparation method for a selenium-rich hair weed product, which belongs to the technical field of food bio-concentration. According to the invention, hair weed cells transforms the inorganic selenium--sodium selenite in a nutrient solution into organic selenium in virtue of the own transformation effect of the cells, so harm to the human body is reduced, and absorption and utilization of selenium by human beings and animals are improved; and the growth rate of the hair weed cells in the process of culture is 30 times of the growth rate of cells of wild hair weed, so rapid growth and reproduction of hair weed are realized. The hair weed cells produced in the invention can be used as a natural biological raw material for selenium supplement and are extensively applied to a variety of health food, beverages and new resource food to meet demands of the human body for selenium. The nutrient solution deprived of the hair weed cells contains abundant hair weed exopolysaccharide which has antiviral activity and can replace hair weed as a raw material for production of functional food. A hair weed selenium enrichment culture method provided by the invention is simple and convenient to operate, poses no pollution to the environment, has low cost and is applicable to industrialized production.

Description

technical field [0001] The invention belongs to the technical field of food bio-enrichment, and in particular relates to a method for preparing a selenium-enriched hair vegetable product. Background technique [0002] Selenium is honored as "the fire of life" by the medical and nutrition circles at home and abroad, and enjoys the reputation of "longevity element", "king of anti-cancer", "patron saint of the heart", "natural antidote" and so on. The content of selenium in human tissue is 1 / 10000000, but it determines the existence of life, and its great effect on human health is irreplaceable by other substances. Selenium deficiency will directly lead to the decline of human immunity. Clinical medicine has proved that more than 40 kinds of diseases that threaten human health and life are related to human selenium deficiency, such as cancer, cardiovascular disease, liver disease, cataract, pancreatic disease, diabetes, reproductive systemic diseases, etc. Whether it is anim...
