Liquid strain medium formula and process for increasing content of glutamic acid of pleurotus eryngii

Abstract

The invention provides a liquid strain medium formula and process for increasing the content of glutamic acid of pleurotus eryngii. The liquid strain medium is prepared from, by weight, 2-3 parts of bean pulp meal, 2-3 parts of silkworm chrysalis meal, 0.3-0.5 part of yeast powder, 0.1-0.5 part of lichen powder, 1.5-3 parts of glucose, 1-3 parts of trehalose, 1-2 parts of aginomoto, 0.5-1 part oftomato extracting solution, 0.7-1.2 parts of apple extracting solution, 0.3-0.5 part of paclobutrazol powder, 0.2-0.4 part of PCPA powder and the balance water. The sum of the weight parts of the components is 100. The components and contents of the liquid medium are changed; on one hand, sufficient nutrients are provided for development of pleurotus eryngii strains, and rapid propagation of the pleurotus eryngii strains is guaranteed. On the other hand, space contamination of the pleurotus eryngii strains in the later inoculation process is avoided, meanwhile, the content of the glutamic acidin the planted pleurotus eryngii is effectively increased, and the taste of the pleurotus eryngii is greatly improved.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a formula and a process of a liquid culture medium for increasing the glutamic acid content of Pleurotus eryngii. Background technique [0002] Pleurotus eryngii Quel, also known as Pleurotus eryngii, belongs to the phylum Fungi, Basidiomycetes, Agaricales, Pleurotaceae, and the genus Pleurotus. The flesh of Pleurotus eryngii mushroom is thick, crisp and tender, especially the stipe is dense, firm and milky white, and can be eaten entirely, and the stipe is more crispy and refreshing than the cap. ", has a pleasant almond fragrance and abalone-like mouthfeel, is suitable for fresh-keeping and processing, and is deeply loved by people. As the market demand for Pleurotus eryngii is also increasing day by day, people have also put forward more requirements for the mouthfeel of Pleurotus eryngii high demands. However, at present, the solid strains used by various ...

AI Technical Summary

Problems solved by technology

However, at present, the solid bacteria culture period adopted by various manufacturers is long, and space infection is easy to occur during the solid inoculation process, which seriously affects the taste of Pleurotus eryngii in the later stage
