Food storage and preservation method

Abstract

The invention provides a food storage and preservation method, and belongs to the technical field of food processing. The food storage and fresh-keeping method comprises the following steps: S1, selecting and washing; S2, soaking treatment; S3, fumigation; and S4, packaging. According to the method, the selected and cleaned food raw materials are put into the treatment solution to be soaked, sterilization and disinfection and cleaning of cell sap are achieved, the cell respiration effect is inhibited, and water supplementation is achieved. Besides, the soaked food raw materials are fumigated in steam, so that a thin steamed skin layer is formed on the surface of the food, a protective layer is formed on the surface of the food, water loss is prevented, isolation is achieved, cell respiration is further inhibited, and water loss is prevented; Finally, the finished food product is subjected to vacuum packaging in a modified atmosphere environment and put into an ice bag, so that water loss is further prevented, the original taste of the food is reserved, the storage and fresh-keeping requirements of the food are met, and the shelf life of the food is prolonged.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a food storage and preservation method. Background technique [0002] Because food is prone to problems such as spoilage and deterioration, the shelf life of food is all shorter. Therefore, people are badly in need of finding a method for food storage and preservation. [0003] At present, the existing food storage and preservation methods include modified atmosphere preservation, vacuum preservation, high temperature sterilization preservation and the combination of the above preservation methods. Although the processed food has a prolonged storage shelf life, dehydration problems will occur during the processing process, which will affect the taste of the food, and the fresh-keeping effect is limited, reducing the value of the food, which is not conducive to food storage and preservation. Contents of the invention [0004] In view of the above-mentioned problems exis...

AI Technical Summary

Problems solved by technology

[0002] Because food is prone to problems such as spoilage and deterioration, the shelf life of food is relatively short. Therefore, people urgently need to find a method for food storage and preservation.

[0003] At present, the existing food storage and preservation methods include modified atmosphere preservation, vacuum preservation, high temperature sterilization preservation and the combination of the above preservation methods. Although the storage and shelf life of the processed food is prolonged, the problem of dehydration will occur during the processing process, which will affect the taste of the food, and the preservation effect is limited, which reduces the value of the food and is not conducive to food storage and preservation
