Abstract

The invention relates to a tear-resistant polyvinyl alcohol fruit / vegetable preservative film. The invention is characterized in that the preservative film is prepared from the following raw materials: camellia seed, peppermint leaf, evening primrose, Lilac, acetone, anhydrous sodium sulfate, wool, titanium white, sodium dodecylsulfate, trypsinase, hydrogen peroxide, wheat starch, acetic acid, acetic anhydride, lauryl methacrylate, polyvinyl alcohol, citrate, corn starch, zinc stearate and a right amount of deionized water. The tear-resistant polyvinyl alcohol fruit / vegetable preservative film has the advantages of favorable mechanical properties, stable structure and favorable air permeability, has favorable antibacterial actions, and is capable of decelerating the fruit / vegetable deterioration caused by endogenous metabolic aging and exogenous microbes, greatly prolonging the preservation period and effectively keeping the fruit / vegetable quality.

Description

technical field [0001] The invention belongs to the field of materials and agriculture, and in particular relates to a tear-resistant 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-...
