Abstract

The invention discloses an environment-friendly degradable edible film packaging material. The environment-friendly degradable edible film packaging material is prepared from the following raw materials in parts by weight: 43-77 parts of modified starch, 22-61 parts of dandelion extract, 13-17 parts of konjac gelatin powder, 32-57 parts of edible gelatin, 21-37 parts of modified casein, 10-15 parts of carboxymethyl cellulose, 3-9 parts of chitosan, 2-7 parts of plasticizers, 7-13 parts of agar, 1-3 parts of citric acid, 2-4 parts of antibacterial liquid, 0.5-1.5 parts of plant extract, 2-4 parts of cactus juice, 2-6 parts of glutinous rice juice and 2-7 parts of carrot powder. The environment-friendly degradable edible film packaging material has the advantages of edibility, capability ofpackaging food, preventing oxygen permeation and protecting the original taste of fatty food, high nutritional value after eating, capability of meeting environmental safety requirements, non-toxicity, safety, high oxygen permeation resistance, water and oil resistance, high temperature resistance, easiness in degradation, high strength, good comprehensive performance and high cost performance.

Description

technical field [0001] The invention relates to the technical field of food packaging materials, in particular to an environmentally friendly degradable edible film packaging material. Background technique [0002] With the rapid development of the modern food industry, people have higher and higher requirements for food packaging. People pay more and more attention to the new food edible film that can solve the contradiction between packaging materials and environmental protection. Edible packaging materials. Edible packaging material is a special packaging material that can be directly eaten as a food ingredient. People have used natural edible raw materials to pack food for a long time, such as using animal casings to make sausage packaging, wrapping stuffing with tofu coating coagulated after boiling soybean milk, and wrapping candies with glutinous rice paper. The rise of plastic films has replaced these natural materials to a large extent, but with the enhancement of ...
