Embodiment

[0014] Choose to pick eight mature ‘Angeluo’ plum fruits, fumigate them with 1.25mg / L ozone gas for 18 hours before storage and transportation at room temperature, pack them in perforated plastic bags, and store them at room temperature.

[0015] The ‘Angonuo’ plum is a late-maturing variety, and the maturity period is early October, when the ambient temperature has dropped significantly. See attached figure 1 , The change of the temperature of plum fruit storage environment. It can be seen from the figure that the ambient temperature is basically maintained in the range of 20-22°C during storage at room temperature.

[0016] See attached figure 2 , The mildew and rotten situation of plum fruits at different treatment times. It can be seen from the figure that when 1.25mg / L ozone gas is used for fumigation before storage, the sealing time has a great influence on the storage effect, and the time is not long enough to achieve the ideal sterilization effect. figure 2 In the mediu...

Abstract

The invention relates to a technical method for reducing putrefactive spoilage of plum fruits. Before the storage and the transportation of the plum fruits at normal temperature, ozone gas of which the concentration is 1.25 milligrams per liter is used to perform fumigation for 18 hours. The ozone acts on microbial cell membranes first so that the components of the membranes are damaged to cause dysbolism and inhibit the growth of the membranes, and then the ozone infiltrates continuously to damage intramembranous tissues until microorganisms are killed so that the putrefactive spoilage of the plum fruits in the storage and the transportation is greatly reduced.

Description

Technical field [0001] The invention relates to a method for reducing mildew during plum fruit storage and transportation, and belongs to the field of postharvest agricultural products. Background technique [0002] Plum (Prunus salicina Lindl.) is one of the characteristic fruits native to my country. The fruit has high commercial value due to its rich nutrition, bright appearance, rich in vitamins, organic acids and minerals. Because it matures in the high temperature season, it belongs to the type of respiration. Once the maturation process is started, the metabolism related to maturity will be strengthened, the respiratory intensity will increase, ethylene will be produced in large quantities, the cell plasma membrane permeability of the fruit will increase, and a series of hydrolytic enzyme activities will increase. Its tissues are softened and accompanied by mildew, which severely shortens the storage life of the fruit and affects the circulation and commerciality of the fr...
