Abstract

The invention discloses a fresh-keeping method for storing and transporting vegetables and fruits in an airtight environment and belongs to the field of fresh-keeping process for vegetables and fruits. The method comprises the following steps: collecting raw materials, pre-cooling raw materials, and air-tightly packaging, storing and transporting the raw materials, wherein an oxygen generating agent which is peroxide is added during the air-tightly packaging and storing process. According to the method provided by the invention, the oxygen generating agent is utilized to have chemical reaction with the CO2 (carbon dioxide) in the airtight environment and the evaporated H2O (water) formed by the vegetables and fruits, thereby generating O2 (oxygen), consuming CO2, relatively increasing the O2 concentration and decreasing the CO2 concentration under the airtight condition, and preventing the vegetables and fruits from anaerobic respiration or/and CO2 poisoning, so as to promote the storage, transportation and fresh-keeping effects for vegetables and fruits and prolong the storage, transportation and fresh-keeping period. The fresh-keeping method provided by the invention has the advantages that the operation is simple and feasible, the production cost is low, the practicability is strong and the batch storage and transportation can be realized.

Description

technical field [0001] The invention relates to the field of fresh-keeping processing of fruits and vegetables, in particular to a storage and transportation of fruits and vegetables in a closed environment 2 CO reduction 2 "Reverse modified atmosphere" preservation method. Background technique [0002] O in the storage environment 2 and CO 2 They are gaseous substrates and products for the respiration of fruits and vegetables, and at the same time, O 2 Participation, CO 2 It is a competitive inhibitor of ethylene function. According to the principle of substrate limitation and product feedback inhibition, it can properly reduce O in the storage and transportation environment. 2 Concentration, increasing CO 2 Concentration can effectively reduce the respiratory metabolism of fruits and vegetables, inhibit the generation and effect of ethylene, reduce nutrient loss, and thus play a role in freshness preservation. This is the basic principle of controlled atmosphere stor...
