Apple ozonization storage method

Abstract

The invention relates to a method for storing apples through ozone treatment. The methed comprises the following steps: firstly, apples with good shapes and without mechanical damages are selected; then ozone sterilization is carried out to fresh fruits selected till the concentration of ethane and aldehyde degrades automatically; the concentration of the ozone for sterilization is 3 mg question mark m<-3> to 9 mg question mark m<-3>; secondly, precooling is carried out; the fruits precooled are put into cartons or wooden boxes and then sealed for 10 hours to 12 hours in a cold storage when the concentration of O3 reaches 18 mg question mark m<3> to 22 mg question mark m<3>; and finally the fruits packed are stored in the cold storage with the temperature of minus 0.5 DEG C to 0.5 DEG C and the relative humidity of 85 percent to 95 percent. The method solves the technical problems of high damage ratio in the fruit quality and difficult control over physiology and fungal diseases when cold storage is carried out to the apples. The method is good in cold storage and refreshing effects with long storage term and low quality damage to the fruits.

Description

technical field [0001] The invention belongs to fruit processing and storage methods, in particular to an apple fruit ozone treatment and storage method. technical background [0002] Apples have good storage performance and are the main fruit supplied to the market throughout the year, but they are easily infected by fungi during storage after picking, causing rot and deterioration. Commonly used chemical preservation methods have problems such as food safety and environmental pollution, and some physiological diseases are prone to occur in the later stage of storage, such as tiger skin disease, bitter pox, etc., resulting in a decrease in the commodity value of the fruit. Therefore, how to maintain the fruit quality of apples and control the diseases of apples during storage has become one of the problems that need to be solved urgently. [0003] At present, low-temperature storage is one of the most effective methods for storage and preservation of horticultural fruit pr...
