Food fresh keeping method using chitosan for cooperating with high-voltage electric field plasma

Abstract

The invention relates to a food fresh keeping method using chitosan for cooperating with high-voltage electric field plasmas, and belongs to the field of food fresh keeping packaging. The method comprises the following steps of soaking fresh fruit and vegetables into a chitosan solution with the concentration being 1 percent; taking out and draining the fresh fruit and vegetables; then putting thefresh fruit and vegetables into a fresh keeping box; sealing an opening; performing packaging; performing cooperated treatment by using high-voltage electric field plasma equipment; performing treatment under the condition of the electric field intensity being 15kV / cm. The chitosan is used for cooperating with the plasmas to perform sterilization storage on the fresh fruit and vegetables; no secondary pollution and no pesticide and chemical residue exist; on the basis of green and environment-friendly effects, the original quality of the fruit and vegetables can be maintained; the shelf lifeof the fruit and vegetables can be obviously prolonged.

Description

1. Technical field [0001] The invention belongs to the field of food preservation, and relates to a high-voltage electric field plasma sterilization and preservation method, in particular to a food preservation method for fresh fruits and vegetables. Specifically, it is a sterilizing and fresh-keeping method of chitosan in cooperation with high-voltage electric field plasma. 2. Background technology [0002] As a country with a large population, China has a large supply and demand for fresh fruits and vegetables, and microorganisms cause the main problem of spoilage of fruits and vegetables. Food poisoning incidents caused by microorganisms are increasing day by day. Therefore, food safety issues about fruits and vegetables are receiving more and more attention. . Traditional food sterilization methods can be divided into physical sterilization and chemical sterilization. Physical sterilization has many limitations due to its equipment, such as high heat, poor sterilization...

AI Technical Summary

Problems solved by technology

Traditional food sterilization methods can be divided into physical sterilization and chemical sterilization. Physical sterilization has many limitations due to its equipment, such as high heat, poor sterilization effect, and high power consumption of equipment. Although chemical sterilization has a good sterilization effect, its application range wide, but there are residues, safety and other issues
