Gel film coating and food hygiene packaging application

Abstract

The invention discloses a gel film coating and food hygiene packaging application, belongs to the technical field of food hygiene and safety, and solves the problems of food spoilage and hygiene safety caused by bacterial growth of existing fresh food in cold-chain transportation, underground storage chambers, refrigerators and other dark, wet and cold environments. The AZO (aluminum-doped zinc oxide), the ITO (tin-doped indium oxide), the ATO (antimony-doped tin oxide), the IZO (indium-doped zinc oxide) and the indium-doped titanium oxide are nanometer materials with near-infrared and intermediate-infrared plasmon resonance characteristics, and the novel antibacterial material is processed on the basis of the near-infrared and intermediate-infrared plasmon resonance characteristics. The method has the advantages of non-toxic and stable raw materials, high antibacterial broad-spectrum property, no light, no contact and low cost, and has strong killing power to bacteria in a dark environment.

Description

technical field

[0001] The invention relates to the technical field of food hygiene and safety, in particular to the application of a gel film coating and food hygiene packaging. Background technique

[0002] During the traditional cold chain transportation, some tropical fruits such as bananas, lemons, pumpkins and other fruits and vegetables need to be stored away from light. The suitable storage temperature is 13-15℃. The refrigerated temperature of the truck should be set at 10-20°C; there are a large number of fruits and vegetables such as tomatoes, cucumbers, bell peppers, lychees, bitter gourds, and cowpeas, which are suitable for storage at about 10°C, so the refrigerated temperature of the transport truck should be set at 8-20°C. 15°C, and the storage time does not exceed two days. Although the refrigerated temperature of the transport vehicle is low, within the temperature range of 10-20 degrees Celsius, the sterilization effect cannot be achieved, and it will sti...
