Abstract

The invention discloses a mushroom-type food fresh-keeping packaging material and a preparation method thereof. The mushroom-type food fresh-keeping packaging material comprises, by mass, 30-50 parts of polyvinyl chloride, 15-30 parts of polyethylene, 5-10 parts of epoxy soybean oil, 1-6 parts of chlorinated paraffin, 2-6 parts of epoxy linseed oil, 5-10 parts of nanometer silica, 0.1-0.8 parts of sodium bisulfate, 0.5-2.5 parts of dicapryl phthalate, 6-12 parts of pentaerythritol, 2-6 parts of a coupling agent and 1-5 parts of a stabilizing agent. The packaging material improves mushroom immunity, induces a protection enzyme system to start, removes redundant free radicals, inhibits membrane lipid peroxidation, protects membrane structure integrity and delays mushroom aging. The packaging material can inhibit generation of spoilage microorganisms such as bacteria and mould, guarantee mushroom quality and realize fresh-keeping effects.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a fresh-keeping packaging material for mushroom-like food and a preparation method thereof. Background technique [0002] Edible fungi (refers to a class of large fungi that are available for use, they are visible to the naked eye, can be harvested by hand, and have fruiting bodies of different shapes. These fruiting bodies are generally born on the ground on fallen tree stumps, dung grass soil, plant root lotus or Born in the underground soil. With the improvement of people's economy and living standards, the requirements for food nutrition are getting higher and higher. Edible fungi are rich in nutrients and contain high protein, various amino acids, vitamins, polysaccharides, minerals, etc. Nutrients and low fat content. Edible fungi also have health functions such as anti-tumor, immune regulation, and anti-virus, and have become a recognized "healthy f...
