Abstract

The invention relates to a polyvinyl alcohol fruit / vegetable fresh-keeping film capable of resisting bacteria. The film is characterized by being prepared from the following raw materials: camellia seed, tea, dried ginger, folium artemisiae argyi, lilac, acetone, anhydrous sodium sulfate, anhydrous ethanol, ammonia water solution, ethylene glycol, triethyl phosphate, ethyl orthosilicate, corn starch, caustic soda, vinyl acetate, polyvinyl alcohol, ammonium persulfate solution, nonylphenol polyethenoxy ether, epoxy soybean oil, a right amount of phosphate and a right amount of deionized water. The polyvinyl alcohol fruit / vegetable fresh-keeping film capable of resisting bacteria has favorable mechanical property, structure stability and favorable air permeability, achieves a favorable antibacterial effect, and can slow down deterioration caused by endogenous metabolic ageing and exogenous microbes of fruits / vegetables, greatly prolong the shelf life and effectively keep the quality of the fruits / vegetables.

Description

technical field [0001] The invention belongs to the field of materials and agriculture, and in particular relates to an antibacterial polyvinyl alcohol fresh-keeping film for fruits and vegetables and a preparation method thereof. Background technique [0002] At present, the storage and preservation methods of fruits and vegetables mainly include low-temperature refrigeration, controlled atmosphere, irradiation, chemical sterilization and plastic wrap packaging. Among them, the fresh-keeping film method is widely used due to its low cost, simple operation, wide application range and obvious effect. The currently used plastic wraps mainly include ordinary plastic wraps, microporous plastic wraps, anti-fog functional plastic wraps, edible plastic wraps and antibacterial plastic wraps. Due to the different fresh-keeping requirements of various fruits and vegetables, a single-function fresh-keeping film cannot meet the requirements. Therefore, it is necessary to develop multi-...
