Abstract

The invention provides a selenium-enriched hericium erinaceus mycelium beverage and a preparation method thereof, and belongs to the technical field of food processing. The selenium-enriched hericiumerinaceus mycelium beverage is prepared from selenium-enriched hericium erinaceus mycelium, a sweetening agent, an acidity regulator, a thickening agent and water. The selenium-enriched hericium erinaceus mycelium is obtained by performing selenium-enriched submerged fermentation on hericium erinaceus mycelium, washing with deionized water and drying, and the organic selenium content of the selenium-enriched hericium erinaceus mycelium is 100-200 mg/kg. The selenium-rich hericium erinaceus mycelium beverage provided by the invention is rich in organic selenium, has unique faint scent of hericium erinaceus, and is a healthy product with unique taste, balanced nutrition and low calorie. The beverage is convenient to drink, safe to prepare, pollution-free, controllable in quality, simple in process and convenient to popularize.

Description

technical field [0001] The invention relates to a selenium-enriched Hericium erinaceus mycelium beverage and a preparation method thereof, belonging to the technical field of food processing. Background technique [0002] Hericium erinaceus (Rull ex F.) Pers belongs to Basidiomycota, Laminobacteria, Polyporaceae, Hericium erinaceae, Hericium erinaceus. It is delicious, nutritious, and has hypoglycemic and antioxidant properties And anti-aging, promote peripheral nerve regeneration, inhibit tumor cell growth, enhance immune regulation and other effects, especially for the treatment of gastric ulcer and gastrointestinal cancer have a significant effect. [0003] Selenium is an essential trace element for the human body, and is mainly involved in the formation of glutathione peroxidase (GSH-Px), thioredoxin reductase (TrxR), selenoprotein P (selenoprotein P, Selp), regulates oxidative stress, redox state, and key cellular events. Selenium deficiency may lead to many diseases ...
