Abstract

The invention discloses an edible film material, an edible film made of the edible film material and a preparation method of the edible film. The edible film material comprises nanocellulose, modified starch and other edible auxiliary materials. With the adoption of the nanocellulose, the mechanical performance and the barrier property of the edible film are improved. The edible film can be widely applied to the inner packing of food such as high-class candies and chocolate.

Description

technical field [0001] The invention relates to an edible film material, an edible film prepared therefrom and a preparation method of the edible film. Background technique [0002] With the improvement of consumers' requirements for food quality and storage period and the continuous enhancement of environmental protection awareness, edible packaging films made of natural biological materials have gradually become a research hotspot. Edible film refers to a composite film formed of edible materials, which is mainly composed of natural macromolecular substances such as lipids, proteins and polysaccharides. Compared with synthetic packaging materials, edible film can be biodegraded without any pollution. [0003] For example, CN102964847A discloses a protein / chitosan composite edible film. The raw materials include 50 parts of zein, 50 parts of wheat prolamin, 20-50 parts of chitosan and 20-30 parts of glycerin. For another example, CN102643554A discloses an edible fish skin...
