Selenium-rich saccharomyces cerevisiae, selenium-rich yeast product and their production process

Abstract

The present invention relates to one kind of selenium-rich Saccharomyces cerevisiae, selenium-rich Saccharomyces cerevisiae product and their production process. Of the selenium-rich Saccharomyces cerevisiae product, each kilogram contains selenium in 4000-8000 mg, and organoselenium accounts for 90-99 wt% of the total selenium content. The process of producing selenium-rich Saccharomyces cerevisiae product includes the following steps: 1. fermenting the selenium-rich Saccharomyces cerevisiae of the present invention in culture medium containing selenium in 10-300 mcg / ml at 26-35 deg.c; and 2. drying the fermented Saccharomyces cerevisiae liquid to obtain the selenium-rich Saccharomyces cerevisiae product. The selenium-rich Saccharomyces cerevisiae product is safe and non-toxic, and may be used in medicine, food, feed and other fields.

Description

technical field

[0001] The invention relates to a selenium-enriched Saccharomyces cerevisiae, a selenium-enriched yeast product obtained from the selenium-enriched Saccharomyces cerevisiae and a production method thereof. Background technique

[0002] Selenium is an essential trace element for humans and animals. It is an important part of various enzymes. Selenium is an important component of glutathione peroxidase. Through oxidation and reduction, it protects biofilms from damage and maintains normal cells. Features. Selenium can also enhance immunity, protect cardiovascular, promote growth, anti-tumor, detoxify, regulate metabolism and other functions. The endemic diseases caused by selenium deficiency in my country include Keshan disease and Kaschin-Beck disease. Selenium-enriched yeast has an obvious effect on supplementing some diseases caused by selenium deficiency. In addition, yeast is rich in nutrients and can play a synergistic effect.
