Example Embodiment

[0013] A kind of method that adds camellia seed oil to prepare preservative film, comprises the following steps:

[0014] (1) Add chitosan into the glacial acetic acid solution with a volume fraction of 1% according to the solid-to-liquid ratio of 1:20, and stir electrically for 4 hours at a temperature of 35°C to fully dissolve it, and filter to remove insoluble impurities. Obtain chitosan solution;

[0015] (2) Mix glycerin and collagen at a mass ratio of 5:1, then add the mixture to the chitosan solution at a mass ratio of 1:4, ultrasonicate for 15 minutes, stir at a low speed for 1 hour, and mix camellia seed oil by mass Add it into the stirring solution at a ratio of 1:10, and add an emulsifier with a mass fraction of 1%, disperse at high speed for 15 minutes, degas under reduced pressure at 0.2MPa for 2 hours, quantitatively cast it in a tetrafluoro mold, and place it at 35 Dry in an oven at ℃ for 24 hours, and dry at room temperature to form a film.

Abstract

The invention discloses a method for preparing a fresh-keeping film by adding camellia seed oil. The film is prepared by compounding chitosan and the camellia seed oil; the raw materials are safe and non-toxic; the film is safe and sanitary to use, reduced in water permeable rate and improved in water resistance, improves the water-retaining and fresh-keeping functions of film-coated food, has smooth texture, toughness, air-permeability, water-retaining performance and antibacterial performance, exerts good fresh-keeping effect, and is improved in market values.

Description

technical field [0001] The invention relates to a method for preparing a preservative film, in particular to a method for preparing a preservative film by adding camellia seed oil. Background technique [0002] With the continuous improvement of people's awareness of environmental protection and food safety, traditional plastic packaging materials have caused serious ecological and environmental problems due to factors such as their inability to biodegrade and difficulty in recycling. Natural packaging materials have generated great interest, so finding new materials that can be used in the food packaging industry from abundant biomass resources has become a research hotspot in the field of fresh-keeping and packaging. The main substrates of edible packaging films are divided into three categories: polysaccharides, proteins and lipids. Among them, polysaccharide films have good compatibility and gas barrier properties. Among polysaccharides, chitosan has a unique molecular s...
