[0030] 1) Harvesting: Select 8 to 9 mature Yaoshan pears for harvesting without injury. At this time, the fruit hardness is greater than 7.0kg / cm 2 , the soluble solid content is about 12.5% ​​to 13.0%, and the harvested fruit is packed into a plastic packaging box, and transported to the storage warehouse or the post-harvest product commercialization processing center within 7 hours for subsequent processing;

[0031] 2) Fumigation: use conventional PE greenhouse plastic film with a thickness of 0.08mm to form a plastic tent with six sides completely sealed and only one door opened on one of the sides. The volume of the big tent is 5m 3, put about 1000kg of harvested Yaoshan pears together with the plastic packing box into the airtight plastic tent through the door left on one side of the plastic tent; fumigate the Yaoshan pears in the tent for 10 hours During the fumigation process, the temperature was controlled at 0°C, and the concentration of 1-MCP was 0.1 μL / L; the door ...

Abstract

The invention discloses a controlled atmosphere fresh-keeping method for Yaoshan snow pears. The controlled atmosphere fresh-keeping method comprises the steps of: filling Yaoshan snow pears which are harvested duly and have no damage into plastic packaging boxes; performing fumigation treatment by using 1-MCP in an enclosed environment; ventilating and performing sterilization treatment by using ozone; filling the sterilized Yaoshan snow pears into plastic boxes or paper boxes in which PE (Polyethylene) micro-pore freshness protection packages are lined; ventilating cold air for the packaged Yaoshan snow pears for pre-cooling treatment; after the pre-cooling treatment, tightly tying the openings of the freshness protection packages; and finally carrying out controlled atmosphere storage, wherein gas parameters in a controlled atmosphere store are adjusted and controlled as follows: 2-3% by volume of O2, 3-5% by volume of CO2, and 90-95% of relative humidity. In comparison with unprocessed Yaoshan snow pears, the storage time of the Yaoshan snow pears adopting the controlled atmosphere fresh-keeping method for the Yaoshan snow pears is prolonged for three months at the same low-temperature storage condition; and in comparison with normal micro-pore controlled atmosphere, the quality of the snow pears after the same storage time is obviously better than the snow pears which are stored in the micro-pore controlled atmosphere.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping and storage of fruits and vegetables, in particular to a modified-atmosphere fresh-keeping method for Yaoshan pears. Background technique [0002] Yaoshan Sydney, named after it is produced in Dayao Mountain, Yongzhou, Hunan, is a specialty of Yongzhou, Hunan. Yaoshan Sydney was successfully bred in the early 21st century and promoted and cultivated in Yaoshan. Yaoshan Sydney has the advantages of beautiful fruit shape, emerald green skin, white and delicate flesh, sweet and sour taste, and no stone cells. Yaoshan Sydney is a typical early-maturing pear, which enters the physiological maturity period in mid-June, and enters the picking period in late June or early July. However, Yaoshan pears were picked in the high temperature season, and the fruit was not resistant to storage. During the storage and transportation process, the fruit was prone to dehydration, yellowing of the peel, browni...
