Abstract

The invention relates to a eugenol-containing curdran-based anti-oxidation film and a preparation method thereof. The raw materials of the antioxidant film include curdlan polysaccharide, eugenol, Tween 80 and glycerin. Its preparation method is to weigh eugenol and add it to water, then add curdlan polysaccharide, Tween 80 and glycerin, stir the membrane liquid at room temperature with magnetic force, then adjust the pH with lactic acid, pour into polytetrafluoroethylene after homogenization Vinyl board, place it in a constant temperature and humidity box (25°C, 50% RH) for about 24 hours, then demould. In the present invention, curdlan polysaccharide is used as a film matrix, and the raw material has the characteristics of thermal gelation, degradability and non-toxicity, and is widely used in the food industry and related fields because of its excellent film-forming and biological properties. In addition, the curdlan base film prepared by the present invention has good oxidation resistance, and the preparation process is simple and easy, and the cost is low. The prepared material can be applied to fields such as films and reduces the use of plastic products to a certain extent. .

Description

technical field [0001] The invention belongs to the technical field of food packaging, and in particular relates to a eugenol-containing curdranyl anti-oxidation film and a preparation method thereof. Background technique [0002] Polymer packaging materials represented by plastics are widely used in the food packaging industry due to their low cost and good mechanical properties. More than one-third of the packaging materials are made of plastics. However, due to the non-complete renewable utilization and non-biodegradability of petroleum-based plastics, it has shown great negative effects in terms of sustainable development. The development and use of biodegradable packaging materials is to make food packaging materials ecological and better protect the ecology. necessary requirements of the environment. [0003] At present, the raw materials of bio-based packaging films that have been studied more mainly include starch, protein, gelatin-chitosan, polylactic acid, bio-pol...
