Problems solved by technology

However, there are few edible packaging films that can combine wrapping properties, excellent sensory properties, and microbial stability.
Coupled with narrow adaptability and high cost, it cannot be widely used commercially and cannot completely replace synthetic packaging materials.
This is mainly because there are still some deficiencies in edible packaging films, such as: poor moisture resistance, poor anti-oxidation and antibacterial properties, etc.

Abstract

The invention provides an edible fish skin collagen active composite membrane and a preparation method thereof. The edible fish skin collagen active composite membrane comprises components, namely fish skin collagen, beta-cyclodextrin, curcumin, Tween-80 and glycerin. The preparation method comprises the following steps: firstly, mixing and dissolving the curcumin and the beta-cyclodextrin into distilled water with the Tween-80 so as to obtain a curcumin emulsifier solution, secondly, dissolving the collagen into the curcumin emulsifier solution so as to obtain a collagen solution, further adding glycerin as a plasticizer, uniformly stirring, leaving stand to remove gases, moving and paving on an organic glass frame, and drying, so as to obtain the edible fish skin collagen active composite membrane. The edible fish skin collagen active composite membrane provided by the invention is good in antioxidation property, can be biologically degraded, is free of environment pollution, is capable of preventing external microorganism from contacting food, and is capable of inhibiting oxidation rotting of the food, therefore, the effects of preserving food and prolonging the shelf life of the food can be achieved.

Description

technical field [0001] The invention relates to an edible fish skin collagen active composite film and a preparation method thereof, belonging to the application technical field of bioactive packaging films. Background technique [0002] With the development of the modern food industry, food packaging is constantly updated, and a new type of food packaging technology material that can improve the contradiction between packaging materials and environmental protection——edible packaging stands out. Edible packaging material means that when the function of packaging is realized, the material can be transformed into an edible raw material for animals or humans. It is a special packaging material that can realize the transformation of the function of packaging materials. Edible packaging material is a kind of waste-free packaging, and it is a resource-based and environmentally friendly packaging material. Edible packaging, that is, edible packaging, is generally composed of starc...
