Selenium-rich hericium erinaceus powder, production method thereof and application thereof as selenium nutrition enhancer

Abstract

The invention discloses a production method of selenium-rich hericium erinaceus powder. The production method comprises the steps: (1) culture of liquid strains, (2) homogenizing of strain liquid, (3)solid fermentation culture, and (4) preparation of the selenium-rich hericium erinaceus powder. The selenium-rich hericium erinaceus powder disclosed by the invention can be applied as a selenium nutrition enhancer. The range of the selenium content of the obtained selenium-rich hericium erinaceus powder reaches the Chinese Standard provisions, the ratio of organic selenium is greater than 99.5%,and the selenium in the selenium-rich hericium erinaceus powder produced by the method disclosed by the invention is absorbable and can obviously improve the activity of glutathione peroxidase in mice. The strains in the production method are matched with a liquid strain production process, and the fruiting time is shortened to about 20 days. The product obtained by the production method has a high selenium content and can be applied to milk beverages, rice and products thereof, wheat flour and products thereof, coarse grain flour and products thereof, bread, biscuits and other conventional foods as a nutrition enhancer, so the scope of application is widened and popularization of selenium supplement in national people is effectively realized by virtue of the selenium nutrition enhancer.

Description

Technical field [0001] The invention belongs to the technical field of biological food nutrition, and in particular relates to a selenium-enriched hericium erinaceus powder and a production method thereof and its use as a selenium nutrition fortifier. Background technique [0002] Selenium is an important trace element and is closely related to more than 50 diseases such as human immunity and cancer. 72% of my country's regions are lacking in selenium, and 800 million people are lacking in selenium. People are also increasingly aware of the importance of selenium. Experts predict that selenium supplementation is expected to replace calcium supplementation and become the largest trace element market. Nowadays, the main way to supplement selenium in Chinese is through health products, which covers very few people. Adding selenium nutritional fortifiers to food is the inevitable direction and trend of popularizing selenium supplementation. [0003] At present, the "Standards for t...

Problems solved by technology

[0004] Patent ZL201010190735.7 discloses a selenium-enriched Hericium erinaceus capsule, and the selenium content in the resulting product is 114.05±8.09mg / kg; while the national standard "Food Nutritional Enhancer-Selenium-enriched Edible Fungi Powder" (GB1903.33-2016 ) stipulates that the total selenium content of selenium-enriched edible fungus nutrition enhancers must reach 180-400mg / kg, and the organic selenium accounts for ≥98% of the total selenium mass percentage; the product in patent ZL201010190735.7 is far from reaching the selenium content standard and the organic selenium ratio has not been measured , cannot be used as a selenium nutrition enhancer

At the same time, the fruiting time of Hericium erinaceus strains used in this patent is about 3 months, and the fruiting time is long
