Abstract

The invention relates to a refreshing storage method for oranges. The method comprises the following steps: 1) picking: picking and collecting oranges, wherein the oranges are gently handled in orderto avoid artificial damage; 2) heat shock cleaning: soaking the oranges in hot water, and then cleaning and draining, wherein the temperature of hot water is controlled within 50-55 DEG C and the soaking time is controlled within 2-4 minutes; 3) spraying preservative: evenly spraying the preservative onto the outer surfaces of the oranges; 4) split charging and warehousing: split-charging orangesinto packaging boxes and placing the packaging boxes into a refrigerator for storage, wherein the temperature of refrigerator is controlled within 4-12 DEG C, the early humidity of the refrigerator iscontrolled within 80%-90% and the later humidity is controlled within 90%-95%. The happening of fruit stem-end rot and black spot can be restrained to some extent and the fruit rotting can be reduced. The refreshing storage method for oranges is ideal, is capable of greatly prolonging the refreshing time of oranges and is capable of guaranteeing the condition of oranges.

Description

technical field [0001] The invention relates to the field of fruit preservation, in particular to a fresh-keeping and storage method for citrus. Background technique [0002] Citrus is rich in flavonoids, monoterpenes, coumarins, carotenoids, propanols, acridones, glycerol glycolipids and other nutrients. Among them, coumarin is an anticancer substance that has been fully affirmed by scientists. The research results show that there are two main pathways for the formation of coumarin's anticancer function: one is that coumarin detoxifies cancer substances through the action of detoxification enzymes; the other is that it antagonizes cancer substances and inhibits the activation of its metabolism. These two aspects of the role mainly in the initial stage of cancer inhibitory effect. Citrus is one of the common fruits in people's daily diet. The fresh-keeping and storage effect of the existing citrus is not ideal, either the fresh-keeping period is not long, or poor handling...
