Ice temperature modified atmosphere preservation method of button mushroom

Abstract

The invention relates to an ice temperature modified atmosphere preservation method of button mushroom, which comprises the following steps: selecting the button mushroom in uniform size, eliminating mushroom bodies with damages, inferiority, diseases and insect pests, and excising mushroom stalk base parts so as to keep equal height; firstly fully pre-cooling in an ice temperature storage, arranging into a special atmosphere modification box equipped with an atmosphere modification nozzle, filling 15%-30% of CO2 gas into the box, controlling O2 at 0.5%-5%, placing into the ice temperature storage, and keeping the temperature of the ice temperature storage at 0.3 DEG C plus or minus 0.2 DEG C. The placement way of the button mushroom in the special atmosphere modification box is as follows: enabling mushroom caps to be upward, enabling mushroom stalks to be downward, and placing layer by layer; and arranging a soft barrier material between adjacent layers respectively. By adopting the ice temperature modified atmosphere preservation method of the button mushroom, the preservation problem of the button mushroom after harvesting can be solved. Spore germination can be inhibited, senescence of the mushroom bodies can be deferred, and the quality of the mushroom bodies can be kept. By performing preservation according to the method, the preservation and storage period of the button mushroom can achieve 15-30 days, and the storage and transportation period of the button mushroom can be prolonged, thereby being conductive to long-distance transportation and selling of the button mushroom and being conductive to developing mushroom planting industry.

Description

technical field [0001] The invention belongs to the field of storage and fresh-keeping of agricultural products, and in particular relates to a method for keeping fresh-keeping of Agaricus bisporus under controlled ice temperature and atmosphere. Background technique [0002] Agarius bisporus (Agarious bisporus) is the largest commercially produced edible fungus in the world today, and it is also the largest canned edible fungus variety that earns foreign exchange through export in my country. It is sold in both domestic and foreign markets, and the market price is high. It is a very promising edible fungus at present. However, the extremely active post-ripening process of post-harvest mushrooms has affected the quality and shelf life of the mushrooms, and caused great losses and restrictions on production, storage and transportation. Moreover, the production sites of mushrooms in our country are scattered, and the links of transportation and processing cannot keep up, and ...
