Method for preparing amino acid selenium by using photosynthetic bacteria

Abstract

The invention discloses a method for preparing amino acid selenium by using photosynthetic bacteria. The method comprises the following steps: preparing a culture medium, carrying out photosynthetic bacteria expanding propagation, forming an amino acid solution, adding selenium, forming an amino acid selenium solution, and the like. The amino acid selenium is organic selenium, can be quickly absorbed after being eaten by people, is capable of obviously increasing the blood selenium content in vivo and enhancing the immunity, performs the function of strengthening the body, and greatly increases the bioavailability of selenium. The amino acid selenium solution obtained by the method can be directly used as a health product; and when people drink a proper amount of the amino acid selenium solution every day, the amino acid selenium solution can supplement the minor element selenium required by the human body every day and enhance the immunity of the human body. The preparation method greatly increases the bioavailability of selenium, is simple, and is not very high in cost.

Description

technical field [0001] The invention relates to the technical field of amino acid selenium preparation, in particular to a method for preparing amino acid selenium by using photosynthetic bacteria. Background technique [0002] Selenium is an essential trace element for life and has many biological functions. In 1988, the Chinese Nutrition Society listed selenium as one of the 15 daily dietary nutrients necessary for the human body. 72% of my country's land is deficient in selenium. According to statistics, about hundreds of millions of people need to supplement selenium. Selenium deficiency can lead to the decline of human immunity, and it is easy to suffer from more than 40 kinds of diseases such as colds, liver diseases, cardiovascular diseases, and cancers. [0003] At present, selenium supplementation mainly relies on inorganic selenium (such as sodium selenite) and organic selenium (such as amino acid selenium). Inorganic selenium has high toxicity and high bioavail...

AI Technical Summary

Problems solved by technology

Inorganic selenium has high toxicity and high bioavailability, and a large part of selenium entering the organism is excreted from the body, causing environmental pollution

Organic selenium is better than inorganic selenium in terms of bioavailability, but the cost of organic selenium is relatively expensive at present

Therefore, the development of selenium-enriched food has not yet achieved ideal results.
