Method for preparing mushroom culture medium

Abstract

The invention discloses a method for preparing a mushroom culture medium. The mushroom culture medium is prepared from the following main culture material and assistant material in parts by weight by the following steps: (1) selecting wheat bran and rice sprouts, sterilizing, and drying for later use; (2) preparing selenium-rich soil of which the zinc element accounts for 2-5% by weight, and mixing the obtained mixture with the wheat bran and the rice sprouts in the step (1) so as to prepare a main material, wherein the selenium-rich soil is a mixture of selenium-rich mineral powder and mud; (3) preparing the assistant material: drying broad leaf wood bits and fermented horse dung, mixing, and crushing into granules with the diameter of 2-3mm; (4) mixing agar, ammonia water, bentonite, sodium selenite, potassium carbonate, ferric sulfate and monocalcium phosphate to obtain a solution, and mixing the obtained solution with the granules in the step (3) so as to form the assistant material; (5) mixing the main material and the assistant material, wherein the weight ratio of the main material to the assistant material is 11:3, and the ratio of wheat bran to rice sprouts and selenium-rich soil in the main material is 6:3:1. The culture medium disclosed by the invention is exuberant in thallus growth and high in biotransformation efficiency, and the cost can be reduced.

Description

Technical field: [0001] The invention relates to the production field of Hericium erinaceus, in particular to a method for manufacturing Hericium erinaceus culture components. Background technique: [0002] 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 is known as "mountain delicacy Hericium erinaceus and seafood bird's nest"; Hericium erinaceus has high nutritional content, with 26.3 grams of protein per 100 grams, 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 barrier function of gastric mucosa...

Problems solved by technology

[0003] 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 the 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
