Problems solved by technology

[0004] In his master's degree thesis "Preparation of Bentonite / PVA Preservative Film and Its Application in Mango Preservation", Huang Huirong prepared a kind of preservative film by using bentonite and polyvinyl alcohol, but it has no bactericidal effect. Dispersion in vinyl alcohol needs to be improved

Embodiment

[0020] A bentonite / PVA sterilizing plastic wrap containing medical stone deodorization is characterized in that it is made of the following raw materials in parts by weight:

[0021] Medical stone 4, mashed garlic 30, polyvinyl alcohol 60, sodium chloride solution 25, ferrous chloride 2, sucrose 3, pyridoxal phosphate 0.5, orange oil 2, bentonite 25, β-cyclodextrin 40, twelve Sodium alkylsulfonate 5, glycerin 3, deionized water 1000, absolute ethanol 600;

[0022] The concentration of the sodium chloride solution is 0.5-2mol / L.

[0023] The preparation method of described a kind of bentonite / PVA sterilizing plastic wrap containing medical stone deodorization is characterized in that, is made by following steps:

[0024] a. Disperse minced garlic in 80-100 parts of deionized water, add ferrous chloride, sucrose, pyridoxal phosphate, enzymatically hydrolyze for 50-70 minutes at a temperature of 30-40°C and a pH of 6-7, then add 80-100 parts of absolute ethanol, ultrasonically ...

Abstract

The invention discloses a medical stone containing bentonite/PVA bactericidal freshness-keeping film with a deodorizing function and a preparation method thereof. The bentonite/PVA bactericidal freshness-keeping film is characterized by being prepared from the following raw materials in parts by weight: 2-4 parts of medical stones, 20-30 parts of mashed garlic, 50-60 parts of polyvinyl alcohol, 18-25 parts of a sodium chloride solution, 1-2 parts of ferrous chloride, 2-3 parts of saccharose, 0.2-0.5 part of pyridoxal phosphate, 1-2 parts of mandarin oil, 15-25 parts of bentonite, 30-40 parts of beta-cyclodextrin, 2-5 parts of sodium dodecyl sulfate, 2-3 parts of glycerinum, 600-1000 parts of deionized water and 100-600 parts of absolute ethyl alcohol. The bentonite/PVA bactericidal freshness-keeping film and the preparation method thereof disclosed by the invention have the benefits that the garlic oil is loaded with the bentonite and is included with the cyclodextrin, so that not only is the problem that organic sulfide has a pungent odor solved, is a sustained release role played, and is the sterilization life of the freshness-keeping film prolonged, but also the dispersibility of the bentonite in a polyvinyl alcohol substrate is improved, and the water resistance of the freshness-keeping film is improved; due to the introduction of the medical stones, the deodorizing function of the freshness-keeping film is realized.

Description

technical field [0001] The invention relates to a fresh-keeping film and a preparation method thereof, in particular to a bentonite / PVA sterilizing fresh-keeping film containing medical stone for deodorization and a preparation method thereof. Background technique [0002] Fresh-keeping film plays an important role in the storage and preservation of fruits and vegetables. Different fruits and vegetables have different requirements on the air permeability and moisture permeability of the fresh-keeping film due to their different water content and respiratory strength. And other problems, because PVA macromolecule contains a large number of light groups, has extremely strong hydrophilicity, makes the water absorption rate of PVA film very high, has affected the application of PVA film on the food preservation on the contrary. Studies have shown that the small size effect and macroscopic quantum dangerous channel effect of nanoparticles can interact with the unsaturated bonds o...
