Abstract

The invention provides a graphene oxide antibacterial fresh-keeping film. The graphene oxide fresh-keeping film comprises polyethylene, a tackifier, an antibacterial agent and an antifog agent, wherein the antibacterial agent is a mixture of herba corydalis bungeanae extract, dandelion herb extract and graphene oxide, wherein the mass of the antibacterial agent is 0.2 to 0.8 percent of polyethylene. The mixed antibacterial agent consisting of the graphene material and the plant extract can well ensure the overall bacterial resistance, the fresh-keeping film is stable in antibacterial effect, the lasting time is long, the storage quality and the storage time of fruits and plantings can be apparently improved, the preparation method is simple in operation, the energy consumption is low, andthe graphene oxide antibacterial fresh-keeping film is suitable for the industrial production.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping materials, in particular to a graphene oxide antibacterial fresh-keeping film. Background technique [0002] With the improvement of people's living standards, the requirements for the freshness of fresh fruits and vegetables are getting higher and higher, and the pursuit of product safety and quality is also increasing. During the storage of fruits and vegetables, not only the respiration will cause the loss of nutrients, but also improper storage will cause the decay of fruits and vegetables. Among them, the action of microorganisms such as bacteria and mold is also an important factor affecting the freshness of fruits and vegetables, which shortens the shelf life of fruits and vegetables to a large extent. Therefore, it is necessary to develop excellent fresh-keeping technologies and materials to keep fruits and vegetables fresh. [0003] Currently commonly used fresh-keeping technologie...
