Fresh-keeping agent for increasing content of erythrothioneine in needle mushrooms

Abstract

The invention discloses a fresh-keeping agent for increasing the content of erythrothioneine in needle mushrooms, which adopts 15 mmol / L, 20 mmol / L and 30 mmol / L methionine solutions. The invention further discloses an application method of the fresh-keeping agent for increasing the content of the erythrothioneine in needle mushrooms. The application method comprises the following steps: soaking the needle mushrooms separately by using 15 mmol / L, 20 mmol / L and 30 mmol / L methionine solutions for 20 minutes; after the soaking is ended, taking out the needle mushrooms; naturally drying the needlemushrooms; loading the needle mushrooms in clean plastic baskets according to a standard of 3 strains per basket, sleeving the baskets with polyethylene bags with a thickness of 0.4 mm, and storing at a low temperature. By adopting the fresh-keeping agent, the content of the erythrothioneine in the picked needle mushroom can be apparently increased, and the fresh-keeping agent for increasing thecontent of the erythrothioneine in the picked needle mushroom has the advantages of apparent effect, low cost, nontoxicity, no side effect, environmental protection, environment friendliness and the like.

Description

technical field [0001] The invention relates to the field of post-harvest preservation of edible fungi, in particular to a preservative for increasing the content of ergothioneine in Flammulina velutipes and a use method thereof. Background technique [0002] As a natural amino acid, ergothioneine is an important active substance in organisms and a unique and multifunctional physiological cell protector. It has the functions of scavenging free radicals, helping the body detoxify, maintaining DNA biosynthesis, etc. It has broad application prospects in food, cosmetics, medicine and other fields. Current research shows that humans and animals cannot synthesize ergothioneine independently, but only have the ability to absorb and retain it. Ergothioneine is only synthesized in a few cereal plants and some large fungi, Neurospora crassa, mycobacteria and other microorganisms. Many edible fungi are rich in ergothioneine, such as Coprinus comatus, Flammulina velutipes, Agaricus bi...

AI Technical Summary

Problems solved by technology

At present, the research on ergothioneine in China is in the initial stage of exploration. Most of the foreign countries focus on the research on its antioxidant properties, and the research on the synthesis pathway of ergothioneine is only concentrated in a few microorganisms. The pathway is still unclear, and there is no report on the method of exogenously regulating its metabolism and increasing its content
