Problems solved by technology

At room temperature, straw mushrooms lose their edible value within 1-2 days after harvesting. In summer, the umbrella opening rate reaches 20% within 3 hours after harvesting. However, when stored below 10°C, they are prone to water seepage and soft rot.
Therefore, the storage and preservation of straw mushrooms has been difficult to solve, directly restricting the development of straw mushroom industry.

Abstract

The invention discloses a preservation method of volvariella volvacea. The preservation method comprises the following steps: pre-cooling the volvariella volvacea, shearing AnsiP-S, preparing volvariella volvacea, processing 1-methylcyclopropene (MCP), and storing and preserving at a low temperature. The conditions such as weight loss, browning and autolysis of the volvariella volvacea processed with 1-MCP during the storage and preservation period can be remarkably improved, and sensory qualities such as good appearance and flavor are maintained. The storage period of the volvariella volvacea processed by the preservation method is prolonged by 7 days in comparison with that of volvariella volvacea which is not preserved and is stored at normal temperature in summer, and is prolonged by 5 days in comparison with that of volvariella volvacea which is not preserved and is stored at a low temperature of 14-16 DEG C, thereby proving that the preservation effect of the preservation method is extremely remarkable. Meanwhile, the preservation method disclosed by the invention is free from toxicity, smell and pollution, is a healthy, efficient and environment-friendly preservation method, and is convenient to operate and low in cost, and has wide application prospects; the problem of preservation which is not solved always in the industrial development of volvariella volvacea is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping edible fungi, and in particular relates to a fresh-keeping method of straw mushrooms. Background technique [0002] straw mushroom( Volvariella volvacea (Bull.ex Fr.) Sing.), also known as Nanhua mushroom, (delicious) stalk mushroom, stalk mushroom, orchid mushroom, sesame mushroom, Chinese mushroom, etc., is an edible fungus that grows in summer and likes high temperature and high humidity , Grass-saprophytic fungi that grow on fiber waste such as straw, cotton, and hemp. The nutritional value of straw mushroom is very high, and it is a very high-quality protein source. It has the reputation of "meat among vegetarians" and "king of mushrooms". The protein content is 25.9%~29.63% by dry weight, second only to boletus (29.7%) in edible fungi. Although the protein content of fresh mushrooms is not as high as that of meat, it is higher than most fruits and vegetables, and the utilization rat...
