The present invention discloses a gradient slow-release active composite film and a preparation method thereof. The active composite film, from inside to outside, is composed of an antioxidative hygroscopic internal layer, at least one gradient anti-microbial antioxidative intermediate layer and at least one waterproof external layer; wherein the antioxidative hygroscopic internal layer is prepared by an alcohol-soluble protein-water-soluble protein substrate and a water-soluble antioxidant; the gradient anti-microbial antioxidative intermediate layer is prepared by an alcohol-soluble protein-water-soluble protein substrate and a lipid-soluble plant essential oil and a water-soluble antioxidant, wherein a mass ratio of the alcohol-soluble protein to the water-soluble protein is (1-2):(1-2); and the waterproof external layer is composed of a hydrophobic alcohol-soluble protein layer.

Gradient slow-release active composite film and preparation method thereof

An alcohol soluble protein gas-liquid interface self-assembled porous membrane and a preparation method thereof are provided. The alcohol soluble protein gas-liquid interface self-assembled porous membrane is prepared from an alcohol soluble protein membrane storage solution by an anti-solvent method. The porous interface membrane is rapidly prepared by an alcohol soluble protein interface self-assembled one-step method and can be rapidly formed within 4 seconds, which greatly improves the preparation efficiency of the alcohol soluble protein membrane. The structure (size, pore diameter, micro porosity) of the alcohol soluble protein interface self-assembled porous membrane is precisely regulated and controlled by regulating and controlling process parameters, and a new preparation solution of an alcohol soluble protein base membrane, which is more efficient and has a modifiable structure compared with an alcohol soluble protein membrane prepared by a traditional solvent evaporation method, is developed.
