The invention relates to a curdlan-based antioxidant film containing eugenol and a preparation method of the curdlan-based antioxidant film. The antioxidant film is prepared from the following raw materials: curdlan, eugenol, Tween 80 and glycerol. The preparation method comprises the following steps: weighing eugenol, adding eugenol into water, adding curdlan, Tween 80 and glycerol, magneticallystirring the membrane solution at room temperature, regulating the pH value with lactic acid, homogenizing the mixture, pouring the mixture into a polytetrafluoroethylene plate, standing in a constant-temperature and constant-humidity box (25 DEG C, 50% RH) for about 24 hours, and demolding the product. According to the invention, curdlan is used as a film matrix, and the raw materials have the characteristics of thermal gelatinization, degradability and no toxicity, so that curdlan is widely applied to the food industry and related fields due to excellent film-forming property and biologicalproperties. In addition, the prepared curdlan base film has good oxidation resistance, the preparation process is simple and easy to implement, the cost is low, the prepared material can be applied tothe fields of thin films and the like, and the use of plastic products is reduced 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...
