Abstract

The invention discloses a preservation method which is suitable for storing edible mushroom. According to the preservation method, a natural preservation agent chitosan is dissolved in water to obtain an aqueous solution, the aqueous solution is sprayed on the surface of edible mushroom to form a film, thereby postponing aging process, reducing loss of nutrients such as sugars, organic acid, vitamin C and the like caused by a respiration, and inhibiting breeding of harmful bacteria; moreover, in conjunction with the modified atmosphere packaging (MAP) technology, two methods achieve synergistic effect, thereby achieving obvious edible mushroom preservation effect. Contrast experiments shown that in comparison with edible mushroom not subjected to any treatment, pleurotus eryngii and Griflola frondosa stored by the preservation method have the advantages of bright surface, high freshness, no objectional odor or brown stain, low nutrient loss and remarkable preservation effect. The preservation method is easy to popularize and apply, capable of prolonging shelf life, thereby achieving a purpose of preservation and storing edible mushroom for a long term.

Description

technical field

[0001] The invention belongs to the technical field of food processing, in particular to a fresh-keeping method of edible fungi, and in particular relates to an application method of chitosan and modified atmosphere packaging technology in the fresh-keeping of edible fungi. Background technique

[0002] Edible fungi belong to the respiratory climacteric type, and they still carry out strong metabolic activities and respiration after picking, which affects the edible value and appearance of edible fungi. The resistance of mushrooms, physical and chemical methods are used to keep the decomposition of edible fungi in the lowest state (dormant state), so as to prolong the fresh-keeping storage time and maintain the edible value and commodity value of fresh mushrooms. The fresh-keeping technologies currently used mainly include cold storage, fresh-keeping, The advantages and disadvantages of various fresh-keeping technologies are briefly introduced below: [0003...
