Application of an edible fungus bag based on walnut shell/meal in strain cultivation

Abstract

The invention discloses an edible mushroom bag based on a walnut shell / dreg and a preparation method and application thereof. The mushroom bag is prepared from the following components in parts by mass: 100 parts of walnut shell / dreg complex, 0.1 to 0.5 part of urea, 0.1 to 1 part of superphosphate, 1 to 2 parts of gypsum and 150 to 160 parts of water; the walnut shell / dreg complex is prepared from the following components in percentage by mass: 30% to 50% of walnut shell, 30% to 50% of walnut dreg, and 10% to 20% of maize straw, and the total mass percentage of the components is 100%. The walnut shell and the walnut dreg, which are by-products in production of walnut milk, are used for comprehensively developing a novel edible mushroom bag, so that the value-added exploitation of the by-products is realized, and the resources are efficiently converted; moreover, the novel mushroom bag is better in substrate nutrition and permeability, thereby facilitating mycelial growth, increasing the fruiting rate, shortening fruiting time, and significantly shortening the production cycle.

Description

technical field

[0001] The invention belongs to the technical field of food, and in particular relates to the application of an edible fungus bag based on walnut shell / meal in strain cultivation. Background technique

[0002] Edible fungus is a kind of large edible fungus, which is more and more popular among consumers because of its delicious taste and rich nutrition. The nutrients needed by edible fungi include carbon sources, nitrogen sources, inorganic salts and vitamins. Mycelia can decompose cellulose, hemicellulose, lignin, starch, pectin and other components into nutrients such as monosaccharides or disaccharides by secreting a variety of enzymes, which can be absorbed and utilized as carbon sources, and can also directly absorb organic acids and Alcohols, etc., but cannot directly use inorganic carbon. The nutrients required by edible fungi can be obtained from sawdust, cottonseed hulls, straw, wheat straw, corn cobs, corn stalks and other substances. In recent y...
