Abstract

The invention discloses a method for preparing an antibacterial food packaging preservation film by doping garlic oil-beta cyclodextrin inclusion compound-clove oil. The method comprises the followingsteps: adding glycerinum, a bentonite-loaded citric acid preservation material, a clove oil-sodium alginate film liquid and a garlic oil-beta cyclodextrin inclusion compound and a chitosan film liquid into water; stirring the mixture at a high speed and dispersing the mixture fully; adding polyvinyl alcohol; putting the mixture in a water bath to be stirred at a high speed to be fully dissolved;stirring the mixture at a low speed; taking the mixture out of the water bath; ultrasonically exhausting air bubbles; cooling the mixture to a room temperature; pouring the mixture to an organic glasspanel; coating the mixture to form a film with a scraper blade; leaving the mixture to stand at a room temperature; and then drying the mixture in a vacuum drying box to prepare the preservation film. Based on the antibacterial action of garlic oil, by means of the beta-cyclodextrin inclusion technology, the garlic oil-beta cyclodextrin inclusion compound is prepared. The garlic oil-beta cyclodextrin inclusion compound is free of irritant smells and shows good thermal stability, light stability and long-term reserved sample stability. The follow-up film forming demand is met fully and a goodmicrobial separating and inhibiting effect is shown.

Description

technical field [0001] The invention belongs to the field of food packaging fresh-keeping materials, and in particular relates to a method for preparing an antibacterial food packaging fresh-keeping film by adding garlic oil-β-cyclodextrin inclusion compound-clove oil. Background technique [0002] Garlic oil is an organic sulfide formed by alliin under the synergistic action of alliinase, pyridoxal phosphate and metal ions after garlic is crushed. It has antibacterial, antiviral, antitumor, protects the cardiovascular system, and promotes sugar Metabolism, improve the body's immunity and so on. Edible cling film, degradable cling film and functional cling film are the development trend of the food packaging industry in the future. Antibacterial cling film is a kind of antibacterial component added to the film-forming material, which achieves antibacterial and bacterial isolation through the slow release of antibacterial substances. , Functional plastic wrap for fresh-keepi...
