Method for maintaining low temperature of postharvest logistic microenvironment of waxberry fruits

Abstract

The invention provides a method for maintaining a low temperature of a postharvest logistic microenvironment of waxberry fruits. According to the method, fruits which are uniform in size and consistent in maturity and have no mechanical damage are selected and placed in a cold storage for low-temperature precooling, a temperature control material is frozen for more than 24 hours at the temperature of subzero 20 DEG C, the waxberry fruits are placed in a logistic bubble chamber, then the temperature control material is placed in the chamber to maintain the low temperature, and the bubble chamber is sealed for logistic transportation. The method has the advantages that a relatively lower logistic temperature can be maintained effectively for the harvested waxberry fruits, the aging process is delayed, microbial activities on the fruit surface are reduced, fruit rot is reduced, and the quality of the fruit goods is maintained better. Meanwhile, the transportation cost, especially the cost for long-distance air transportation can be reduced due to reduced weight of a coolant when the waxberry fruits are transported with the method, the problem of humidity increase in the logistic microenvironment caused by ice bag breakage in an application process of common ice blocks can be solved simultaneously, and waxberry fruit rot can be reduced. The method can further be applied to other horticultural products which have no peels, are prone to rot and the like.

Description

technical field [0001] The invention belongs to fruit storage and transportation, and relates to a method for maintaining a suitable low temperature in the post-harvest logistics microenvironment of bayberry fruit. Background technique [0002] In the process of fruit sealing and logistics, the microenvironment temperature of the sealing is often too high due to high external temperature and vigorous respiration of the fruit itself, resulting in abnormal respiration and metabolism of the fruit, especially for fruits with high water content, abnormal microbial activity on the surface, and accelerated fruit ripening and aging. The fruit rots, the quality deteriorates, and it is difficult to maintain the normal quality and commerciality of the fruit. Appropriate low temperature conditions are an effective way to maintain commerciality in the logistics process of horticultural products. In the past, the method of using ordinary ice cubes can maintain a suitable low temperature,...

AI Technical Summary

Problems solved by technology

In the past, the method of using ordinary ice cubes can maintain a suitable low temperature, but problems such as rot caused by high humidity and excessive transportation costs caused by the large amount of ordinary ice cubes have caused excessive rot loss and quality decline in the logistics process of red bayberry fruit, making it difficult to achieve The economic benefits in the logistics process and the limitation of the logistics radius also greatly limit the large-scale development of the red bayberry industry
