Abstract

The invention discloses a preparation method of an anti-oxidation fish protein edible film, which comprises the following technical processes: dissolving the crushed fish pulp into an acidic aqueous solution to prepare a film solution by the steps of heating, centrifugalizing, adding a plasticizer and an antioxidant, stirring, defoaming and the like; and pouring the prepared film solution into anorganic silicon resin frame to prepare the anti-oxidation fish protein edible film by drying and stripping. In the invention, domestic high-yield fresh water fishes are taken as main raw materials, thereby developing a new way for deep processing of fresh water fishes; the oxidation resistance of the protein film can be controlled by regulating the additive amount of the antioxidant; and the prepared transparent protein film not only has good mechanical strength and oxygen gas and ultraviolet ray shielding performance but also has penetration resistance and heat sealing performance, can be used for replacing plastic films for packaging seasonings of instant noodles, simulated crab sticks and the like, can be eaten together with the packaged food, and can not pollute food and environment.

Description

technical field

[0001] The invention relates to the development field of an environment-friendly packaging film, in particular to a preparation method of an edible film of antioxidant fish meat protein. Background technique

[0002] Edible films mainly use protein and starch that can be digested and absorbed by the human body as basic raw materials, add edible plasticizers such as glycerin and sorbitol, and form a film with certain mechanical strength and Choose a permeable film with a dense structure that can partially replace plastic packaging materials. Since the edible film can be eaten together with the packaged food and does not pollute the food and the environment, it has become a research hotspot of packaging materials at home and abroad in recent years and has begun to be adopted by the food industry.

[0003] The types of edible films can be divided into polysaccharides, fats and proteins according to the film-forming raw materials. Although the polysaccharide ed...
