Abstract

The invention discloses a gulfweed polysaccharide-based edible packaging film. The packaging film comprises, by weight, 56-82 parts of wheat flour, 20-38 parts of gulfweed polysaccharides, 2-10 parts of sucrose, 0.2-0.3 part of active polypeptides, 2-10 parts of vegetables, 5-15 parts of eggs, 10-25 parts of chitosan and 2-10 parts of water, and a weight ratio of the gulfweed polysaccharides to the sucrose is (2-15):1. Materials daily eaten by people are adopted as the raw materials of the packaging film, so the produced packaging film can be used as a packaging film for foods and medicines, has good instant solubility and mechanical performances, also can be used as a food to relieve hunger, and can remove free radials on the surfaces of the foods, delay the oxidation time of the foods and facilitate the prolongation of the shelf life of the foods and the improvement of the quality of the foods when used for packaging fresh vegetables or meat products.

Description

technical field [0001] The invention relates to an edible packaging film, in particular to an edible packaging film based on sargassum polysaccharide. Background technique [0002] Polysaccharide film is made of various polysaccharides (such as starch, chitosan, cellulose, sodium alginate, colloid, etc.) as the main raw material. It is a kind of edible packaging film that has been studied and applied earlier. advanced features. Polysaccharide films are chemically stable and suitable for long-term storage, but generally have poor water resistance. The protein film is made of plant protein (such as soybean protein, corn protein, wheat gluten, etc.) and animal protein (such as whey protein, egg white protein, fish myofibril protein, etc.), and is cross-linked with polypeptide chains through disulfide bonds film forming. The protein film is easy to digest, rich in nutrition, good mechanical properties, and has excellent oxygen, carbon dioxide and oil barrier properties, but p...
