Refreshing method for prolonging shelf life of stored south fruit pears

Abstract

The invention provides a refreshing method for prolonging the shelf life of stored south fruit pears, which comprises the steps: selecting high-quality south fruit pears, harmlessly harvesting from September 5th to September 15th in every year; processing the picked south fruit pears by means of 1-methylcycloproene in a sealed large curtain for 18-24 hours within 24 hours; classifying and packing into special refreshing bags for the south fruit pears produced by the National Engineering and Technology Research Center for Agricultural Products Refreshing, wherein each bag is 15-20kg; pre-ripening for 5-7 days at 20-25 DEG C; putting the south fruit pears into a refrigerated warehouse for precooling for 24-48 hours at the temperature of 0 DEG C + / -0.5 DEG C; tightly binding openings, wherein gas indexes in the bag are that O2 can not be less than 5%, and CO2 can not be higher than 1.0%; and storing in the refrigerated warehouse at the temperature of 0 DEG C + / -0.5 DEG C. The method can store the south fruit pears for 6-8 moths, obviously prolong the shelf life of the stored south fruit pears, lead the stored south fruit pears to have proper color, fine and crispy fleshes, and keep the unique aromas and good sweet and sour taste, and has good shelf quality.

Problems solved by technology

At present, the main fresh-keeping technology of Nanguo pears in production areas is still the traditional cold storage. Although it can keep Nanguo pears from rotting for a long time, the color, aroma and taste of Nanguo pears after long-term refrigeration will deteriorate. Moreover, after 6 months of refrigeration, they will be kept at room temperature. During the shelf life, the fruit skin browns seriously, and the normal temperature shelf only lasts for 2-3 days. Sometimes, serious browning occurs when it is out of the warehouse, which seriously reduces the value of the commodity. The relatively lagging storage technology of Nanguo pear will seriously restrict the cultivation area and the increasing output. The benign development of Nanguo pear industry
