Preservation method capable of simulating vital activity rhythm of cold-sensitive fruits and vegetables to reduce cold damage

Abstract

The invention discloses a preservation method capable of simulating vital activity rhythm of cold-sensitive fruits and vegetables to reduce cold damage, and provides a fruit and vegetable preservation and fresh-keeping method with a long preservation time and a good fresh-keeping effect, based on diurnal change laws of natural environment temperature and physiologic growth characteristics of the fruits and vegetables in the growth process of the fruits and vegetables. Particularly, the preservation method comprises the step of preserving the treated and sealed fruits and vegetables in a constant temperature humidity chamber under a temperature rhythm mode. With adoption of the temperature rhythm high-humidity preservation technology, the longer preservation and fresh-keeping time and the better preservation quality can be achieved by physiologically accommodating the fruits and vegetables, inhibiting the respiratory action of the fruits and vegetables, preventing the cold damage, and reducing moisture loss of the fruits and vegetables by keeping high humidity; the fresh-keeping effect is apparently better than the constant temperature preservation mode and the other temperature-variable preservation modes; the preservation method is suitable for various cold-sensitive fruits and vegetables.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping and storage of fruits and vegetables, in particular to a fresh-keeping method for simulating the life activity rhythm of cold-sensitive fruits and vegetables and reducing cold damage. Background technique [0002] Because the harvest of fruits and vegetables is seasonal, it is of great significance to adopt reasonable storage methods to maximize the storage period of fresh fruits and maintain the quality of fruits and vegetables. To obtain a longer storage period and better quality of fresh fruits and vegetables, the following conditions need to be met: prevent microorganisms from causing rot and deterioration of fruits and vegetables; suitable storage temperature should not only inhibit the respiration of fruits and vegetables, avoid the consumption of nutrients, but also avoid temperature Too low will cause chilling damage; suitable humidity can prevent fresh fruits and vegetables from deh...

Problems solved by technology

[0004] However, many cold-sensitive fruits and vegetables that are sensitive to low temperature, especially tropical and subtropical fruits and vegetables, can be stored at a temperature above the critical temperature of chilling injury to avoid the occurrence of chilling injury, but the physiological activities of fruits and vegetables are relatively active, and the loss of various nutrients is relatively large. Quality decline; when stored below the critical point temperature, the cell structure of fruits and vegetables will be damaged, the disease resistance and storage resistance of the fruit itself will be reduced, and symptoms of chilling damage will appear, thus affecting the edible and commercial value of fruits and vegetables
