Problems solved by technology

[0002] In the process of production, transportation, packaging, storage, sales, etc., foods with high oil content are very susceptible to corruption due to the influence of the external environment, which will eventually lead to a decline in food quality and nutritional value, and may also damage human health. Potentially dangerous, these foods will lose their original quality after spoilage and will not be accepted by consumers

Abstract

The invention provides a preparation method of a food antioxidation packaging film. The preparation method includes: taking and adding bentonite, kaolin and diatomite into water, heating, stirring while adding a coupling agent solution, continuing stirring for reaction, filtering, drying, and smashing to obtain mixed filler; mixing HDPE, EVA and a silane coupling agent, sending a mixture into a single-screw extruder for extrusion, and granulating to obtain base material particles; adding quercetin into micropowder silica gel, mixing, mixing with the mixed filler, the base material particles, microcrystalline cellulose, lecithin, polylactic acid and starch, feeding into a double-screw extruder for extrusion, and pressing to form a film through a flat-plate vulcanizing machine. The food antioxidation packaging film is prepared by using HDPE and EVA as base materials and quercetin as an antioxidant and has high tensile strength and good humidity-resisting oxygen-resisting performance.

Description

technical field [0001] The invention belongs to the technical field of food packaging materials, and in particular relates to a preparation method of a food anti-oxidation packaging film. Background technique [0002] In the process of production, transportation, packaging, storage, sales, etc., foods with high oil content are very susceptible to corruption due to the influence of the external environment, which will eventually lead to a decline in food quality and nutritional value, and may also damage human health. Potentially dangerous, these foods will lose their original quality after deterioration and will not be accepted by consumers. In view of the perishable deterioration of fat-containing food or fat-rich food, food manufacturers are also constantly improving production technology and production technology, such as adding food antioxidants to food raw materials during the food manufacturing process, coating and spraying food on the surface of food Or impregnatin...
