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

Abstract

The invention discloses a fresh-keeping method for reducing cold damage by simulating the life activity rhythm of cold-sensitive fruits and vegetables. Based on the diurnal variation law of natural environment temperature and the physiological growth characteristics of fruits and vegetables during the growth process of fruits and vegetables, a new storage and preservation method of fruits and vegetables with long storage time and good fresh-keeping effect is proposed. Specifically, the processed and sealed fruits and vegetables are put into a constant temperature and humidity box in a temperature rhythm mode for storage and preservation. By adopting the temperature rhythm high humidity storage technology of the present invention, the fruits and vegetables can be physiologically adjusted, the respiration of the fruits and vegetables can be inhibited and the occurrence of chilling damage can be prevented. quality. The preservation effect is obviously better than that of constant temperature storage and other variable temperature storage temperature modes, and it is suitable for all kinds of 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...
