Production method of selenium-enriched hericium erinaceus culture

Abstract

The invention discloses a production method of a selenium-enriched hericium erinaceus culture. The selenium-enriched hericium erinaceus culture is prepared by the following culture main materials and accessories in parts by weight: (1) cotton seed hulls and wheat bran are selected to disinfect and dry for future use; (2) selenium-enriched soil containing 2-5 wt% of zinc element is prepared, and is a mixture of selenium-enriched mineral powder and soil; the mixture is mixed with the cotton seed hulls and the wheat bran in the step (1) for forming the main materials; (3) the accessories are prepared; broad leaf wood chip and dry cow dung are mixed after being dried, and are smashed to particles with 2-3 mm of diameters; (4) agar, urea, bentonite, sodium selenite, ammonium molybdate, iron sulfate and monocalcium phosphate are mixed to prepare solution; and an obtained solution is mixed with the particles in the step (3) to form the accessories; (5) the main materials and the accessories are mixed; the weight ratio of the main materials and the accessories is 11: 3; and the ratio of the cotton seed hulls to the wheat bran to the selenium-enriched soil in the main materials is 6: 3: 1. The culture of the invention has the advantages of vigorous growth of thallus, higher content of selenium in hericium erinaceus, higher nutritional value of thallus, high utilization rate of bacterial strains to the culture, high biological conversion rate and low cost, and improves the economic benefit for cultivating hericium erinaceus.

Description

[0001] Technical field: [0002] The invention relates to the production field of Hericium erinaceus, in particular to a method for manufacturing Hericium erinaceus culture components. [0003] Background technique: [0004] Hericium erinaceus is a famous and precious traditional Chinese dish, with tender meat, fragrant taste and delicious taste. It is one of the four famous dishes (hericium, bear's paw, sea cucumber, shark's fin). It has the title of "mountain delicacy Hericium erinaceus and seafood bird's nest"; Hericium erinaceus has a high nutritional content, containing 26.3 grams of protein per hectogram, which is twice that of shiitake mushrooms. It contains up to 17 kinds of amino acids, of which 8 are needed by the human body. Every 100 grams of hericium contains 4.2 grams of fat, which is a veritable high-protein, low-fat food, and is also rich in various vitamins and inorganic salts. Hericium erinaceus has the effects of increasing appetite, enhancing the barr...

Problems solved by technology

[0005] At present, Hericium erinaceus cultures on the market use 26% wood chips, 20% wheat husks, 2% bentonite or calcium carbonate, 1% sugar, and 1% superphosphate as the main raw materials to cultivate Hericium erinaceus, and the carbon source nutrition of miscellaneous wood chips The elements are single, and the growth environment of the cultivated Hericium erinaceus has many limiting factors, and the yield is relatively low, and wheat husk is selected as the nitrogen source for the growth of Hericium erinaceus, and its nitrogen element is difficult to be decomposed and absorbed by the root system of Hericium erinaceus, which is not conducive to The expansion of Hericium erinaceus strains and caps has resulted in less nutritional value and ingredients of Hericium erinaceus, and lower content of trace elements, which is not conducive to people's normal nutritional intake
