Abstract

The invention discloses a starch-based edible packaging film and a preparation method thereof. The packaging film is prepared from the following raw materials in parts by weight: 65 to 90 parts of cassava starch, 12 to 18 parts of sorbitol, 10 to 15 parts of glycerinum, 1 to 3 parts of lauric acid, 3 to 6 parts of ferulic acid, 1 to 3 parts of hydroxymethyl cellulose, 8 to 12 parts of pullulan, 60 to 70 parts of chitosan, 55 to 65 parts of sodium alginate, 20 to 30 parts of gelatin, 1 to 3 parts of tea polyphenol, and 0.5 to 2 parts of butyl anisole. According to the preparation method, the cassava starch, the sodium alginate and the chitosan are used as a film forming matrix, and various additives are added, so that the prepared packaging film is good in stretchability, oxidization resistance and antibacterial property, high in obstruction property and good in packaging effect; and moreover, the film preparation method is simple, the film material is edible and has certain nutritional value, and the starch-based edible packaging film is suitable for being used as internal package of food.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, in particular to a starch-based edible packaging film and a preparation method thereof. Background technique [0002] Petroleum-based plastics are light, cheap, and have good performance, so they are widely used in food packaging and fresh-keeping fields. However, because they are difficult to degrade, while plastic packaging brings benefits and convenience to people, its waste also causes serious harm. Environmental pollution threatens people's health. Some food packages are not stable in nature when heated, and will release carcinogens, which are very harmful to the human body. Therefore, degradable natural non-toxic edible packaging materials have gradually become a research hotspot in the field of food packaging. [0003] The enhancement of people's awareness of environmental protection and the improvement of food quality requirements have promoted the research of edible packagi...
