Fresh keeping method of russula lepida with kojic acid

Abstract

The invention discloses a fresh keeping method of russula lepida with kojic acid. The method comprises the following steps of selecting russula lepida which is free from diseases and insect pests, free from mechanical damage, uniform in color and consistent in maturity, putting the selected russula lepida in a kojic acid solution, performing soaking for 8-14min, taking out the soaked russula lepida, performing draining to remove excessive moisture, and performing natural airing. Compared with the prior art, the method disclosed by the invention has the advantages that soaking treatment with kojic acid is performed, so that the moisture dissipation of the russula lepida during a storage period can be delayed, occurrence of brown stains can be reduced, the descent rate of the content of amino acids in the russula lepida can be retarded, and the storage time of the russula lepida can be prolonged; besides, 0.1-0.3% of leucine is added to the kojic acid solution, so that the bacteriostasiseffect of the kojic acid solution can be further strengthened, and the occurrence of the brown stains can be effectively reduced; and kojic acid sources are rich, the fresh keeping method of russulalepida disclosed by the invention is low in cost and easy to operate, and has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping edible fungi, and in particular relates to a method for using kojic acid to keep red mushrooms fresh. Background technique [0002] Russula, scientific name Russula lepidaFr., also known as beautiful russula, red mushroom scale, belongs to Basidiomycetes, Agaricales, Russulaceae, is a rare and precious wild edible fungus, distributed in Liaoning, Jiangsu, Fujian, Sichuan and Yunnan and other places, it grows in groups or alone on the humus ground in the forest every summer.

AI Technical Summary

Problems solved by technology

[0003] However, Russula is a respiratory climacteric fruit, which still carries out respiration and metabolic activities after picking. The fruit body contains a lot of water, the skin is weak, and it is easy to be infected by pathogenic bacteria, lose color, fragrance, taste, shape, etc., making nutrition The value and commodity value are reduced, which seriously hinders the supply of russula from the place of origin to the sales market. There is an urgent need for suitable fresh-keeping methods to extend its storage period, but there are no reports related to the preservation of russula
