Abstract

The invention relates to the technical field of preparation of gelatin films, in particular to a preparation method of a cleaning type bactericidal gelatin film. The method comprises the following steps: fructus kochiae is processed, and liquid medicine powder is obtained; dry scales of grass carp are taken and processed, enzymatically hydrolyzed scales are obtained and processed, and a gelatin liquid is obtained; chitosan powder is obtained from waste shrimp shells as a raw material by processing; chitosan acid liquor is prepared; a surface active compound, the gelatin liquid, the liquid medicine powder, solid hydrogen peroxide and tea polyphenol are mixed, and a mixed gelatin liquid is obtained; finally, the mixed gelatin liquid is poured into a tape casting machine for tape casting, drying is performed, and the cleaning type bactericidal gelatin film is obtained. Alkyl amidopropyl dimethylamine betaine is attached to the surfaces of colloidal particles and tears oily film layers ofoil stains, so that an obvious cleaning effect is realized; the gelatin liquid also contains various unsaturated fatty acids, oil in food can be prevented from getting mouldy due to oxidative deterioration, and accordingly, the cleaning type bactericidal gelatin film realizes the bactericidal effect and has few toxic and side effects and broad application prospect.

Description

technical field [0001] The invention relates to the technical field of gelatin film preparation, in particular to a preparation method of a clean sterilizing gelatin film. Background technique [0002] Gelatin, as an extract of animal collagen tissue, is a natural polymer and biomacromolecular material. It has good biocompatibility, non-antigenicity, hemostasis and promotion of tissue healing. Therefore, gelatin is also widely used in the pharmaceutical and chemical industries. my country's gelatin resources are rich in reserves, wide in sources, and low in price. Due to gelatin's good reactivity, film-forming properties, coagulation properties, biocompatibility, degradability, green environmental protection and renewable properties, it has become a popular resource in recent years. To become a research hotspot in the field of biomacromolecular materials science. However, its application is limited due to its low thermal stability, poor mechanical properties, water swelling...
