Embodiment

[0020] A kind of sterilizing and fresh-keeping film containing clove essential oil is characterized in that, the preparation technology of this material comprises the following steps:

[0021] a. Cloves are chopped and added to ethanol, under magnetic stirring conditions, refluxed for 3 hours, cooled after the end, filtered to retain the filtrate, to obtain an ethanol solution of clove essential oil;

[0022] b. Add cornstarch to the resultant of step a, ultrasonically disperse evenly, make a suspension, transfer the suspension to a drying oven, fully dry, and grind to obtain a cornstarch mixture that absorbs clove essential oil;

[0023] c. Add β-cyclodextrin into deionized water, stir to dissolve, then add the mixture obtained in step b and sodium dodecylsulfonate, conduct inclusion reaction by ultrasonic method for 2 hours, then cool and crystallize, vacuum filter, 40°C Dry to obtain β-cyclodextrin inclusion compound;

[0024] d. Add chitosan to the acetic acid solution, s...

Abstract

The invention discloses a clove essential oil contained sterilization plastic wrap and a preparation method thereof. The advantages lie in that corn starch is taken as a carrier to adsorb clove essential oil, beta-cyclodextrin is used for wrapping, dispersity and charge capacity of the clove essential oil can be increased, fusion of the clove essential oil in a wrap base is promoted, waterproofness of the material is improved, sterilization life of the clove essential oil is prolonged, and slow-release effect is achieved; on the other hand, degradation velocity of the material is increased by the adoption of the corn starch, environment friendliness is achieved, and sustainable development is facilitated.

Description

technical field [0001] The invention relates to a bactericidal and fresh-keeping film, in particular to a sterilizing and fresh-keeping film containing clove essential oil and a preparation process thereof. Background technique [0002] Clove essential oil is extracted from cloves, a tree of the family Myrtleaceae, which has strong antibacterial and antioxidant effects. It has been officially approved by the FDA as a food additive. The main active substance is eugenol (2-methoxy-4-(2-propenyl)phenol), which accounts for 90-95% of clove essential oil. Scholars have proved that clove essential oil has stronger antioxidant capacity than traditional chemically synthesized antioxidants BHA, BHT, etc. Clove essential oil also has a very effective ability to inhibit the growth and reproduction of microorganisms. Some researchers have added clove essential oil to edible films to inhibit the reproduction of harmful microorganisms and pathogens. Naveena et al. used clove essential o...
