Abstract

The invention discloses a selenium-enriched black fungus culture material and a preparation method thereof; the selenium-enriched black fungus culture material comprises a mixture A and a mixture B; the weight of the mixture A is 44-48% of the total weight of the culture material; the mixture A is composed of the following components in percentage by weight: 75-85% of weed tree sawdust, 12.5-18% of bran, 0.5-1.5% of bean flour, 0.5-1.5% of peanut bran, 0.5-1.5% of sugar, 0.7-1.5% of light calcium carbonate and 0.3-1% of quick lime; the weight of the mixture B is 52-56% of the total weight of the culture material; and the mixture B is composed of the following components in percentage by weight: 0.004-0.012% of selenium fertilizer and 99.988-99.996% of water. Black fungus cultured by the invention is rapid in hypha growth speed and good in growth trend; black fungus buds grow out early during the bud accelerating period; the black fungus buds can grow fast; the yield can be effectively increased; the product quality is improved; furthermore, the preparation method is lower in production cost and simple and convenient to operate; and thus, the preparation method is beneficial to popularization, application and scale production.

Description

technical field [0001] The invention relates to a selenium-enriched black fungus culture material and a preparation method thereof, belonging to the technical field of selenium-enriched product development. Background technique [0002] Selenium is an essential trace element for the human body and an important part of the strongest antioxidant enzyme in the human body - glutathione peroxidase. It has anti-oxidation, anti-aging, protection of damaged cells, improvement of human immunity, prevention Multiple biological functions such as carcinogenesis, detoxification, and beauty. Therefore, selenium is called "the king of anti-cancer elements" and "human immune activator" by scientists. The Chinese Nutrition Society also lists selenium as one of the 15 essential nutrients for the human body. A large number of clinical experiments at home and abroad have proved that selenium deficiency in the human body can cause dysfunction of some important organs and lead to many serious di...
