Abstract

The invention provides a selenium-rich culture medium for hericium erinaceus. The selenium-rich culture medium for hericium erinaceus is mainly prepared from wood flour, bran, selenium-rich fungus grass and gypsum. The invention further provides a method for producing hericium erinaceus with the selenium-rich culture medium for hericium erinaceus. A traditional production method of a hericium erinaceus strain is changed, a liquid strain technology is utilized in hericium erinaceus strain production, and a selenium-rich liquid strain is prepared; meanwhile, the solid selenium-rich culture medium and a secondary selenium enrichment method are adopted, and produced hericium erinaceus is high in selenium content and high in nutritive value. Production efficiency is improved, and production cost is greatly reduced; besides, the production method is simple in process, and the produced strain is high in utilization rate and low in contamination rate.

Description

technical field [0001] The invention belongs to the field of edible fungus production, and in particular relates to a liquid fermentation medium of Hericium erinaceus and a method for producing Hericium erinaceus by using liquid strain technology. Background technique [0002] Hericium erinaceus, also known as monkey mushroom, Hericium erinaceus, Hericium erinaceus, is a traditional and precious dish in my country. It is tender, fragrant, delicious and delicious. Hericium erinaceus is flat in nature, sweet in taste, beneficial to the five internal organs, and helps digestion; it has the effects of invigorating the stomach, tonifying deficiency, anti-cancer, and nourishing the kidney essence; it is mainly used for less food and loose stools, gastric and duodenal ulcers, superficial gastritis, Neurasthenia, esophageal cancer, gastric cancer, dizziness, impotence and other diseases, have an auxiliary effect on the treatment of intestinal cancer. Hericium erinaceus is an excell...
