Embodiment 1

[0045] Such as figure 1 As shown, the invention provides a kind of modified atmosphere fresh-keeping packaging method for cherries, comprising the steps of:

[0046] Cherry picking: pick 7-8 mature cherries on sunny mornings after the dew dries up or on cloudy days. It is not suitable to pick cherries in hot afternoons, rainy days or after rains. When picking, choose fresh, plump, no peculiar smell, no pests and diseases, and no obvious mechanical damage. For cherries, put the picked cherries in an incubator with ice boxes or ice packs on the upper and lower floors and transport them to the processing site, then put the cherries in the soaking tank for grading and selection, and divide the cherries into different grades according to the specifications, and perform preliminary cleaning , remove sundries.

[0047] S1. Pretreatment: Soak the cherries in a mixture of ice and water at a temperature of -1 to 1°C for 30 minutes, and ensure that the cherries are cooled to below 5°C w...

Abstract

The invention relates to a method of preserving and packaging cherry in controlled atmosphere, including the steps of picking cherry, transporting at low temperature, grading and sorting, washing primarily, chilling, washing and sterilizing, packaging in controlled atmosphere, sterilizing by ultraviolet, and storing. The method belongs to the technical field of cherry preserving and packaging process and cold chain transportation; by subjecting the fresh cherry to chilling, low-oxygen gas controlled-atmosphere packaging, secondary sterilizing and low-temperature high-humidity storage, cold damage index of the cherry is decreased, microorganism control is under control, breath strength of the cherry is reduced, pulp hardness and fruit sourness are maintained, shelf life is prolonged, and fresh taste can be maintained; the method is nontoxic, harmless and free of residue, the whole preserving process employs harmless treatment, the operation method is simple and easy, and the method is a modern cherry preserving and packaging process that can maintain high cherry quality and effectively prolong the shelf time.

Description

technical field [0001] The invention belongs to the technical field of cherry fresh-keeping packaging process and cold chain transportation, and in particular relates to a modified atmosphere fresh-keeping packaging method for cherries, which is used to improve the fresh-keeping quality and extend the shelf life of cherries after they are picked. Background technique [0002] Cherry is a high-grade fresh fruit, which is mostly ripe in late spring and early summer when fruit is in short supply. When ripe, it has a delicious color, juicy meat, sweet and sour taste, rich nutrition, and has high medical and health care value, so it is deeply loved by consumers. Therefore, higher economic benefits can also be obtained. However, the cherry skin is thin and juicy, with high water content, so it is not resistant to storage and transportation. After picking, it is easy to show browning and rot during storage and transportation at room temperature. The natural fresh storage period of ...
