The existing edible starch film mainly uses pure starch as the main raw material, but the pure starch film has high brittleness, and glycerol, sorbitol and other plasticizers need to be added for molding, which not only increases the production cost of the taste film, but also is harmful to people's health due to the use of plasticizers. Therefore, the present application uses edible starch and cassava starch as the main raw material, and uses the high molecular chain characteristics of cassava starch molecules (such as the linear structure of amylose and the branched structure of amylopectin) to insert between the edible starch molecules to weaken the hydrogen bond density, effectively improve the flexibility and ductility, so as to form a continuous film by gelatinization and intermolecular hydrogen bond crosslinking, so that the molding difficulty of the starch film is lower, the film strength is effectively improved, and the use of plasticizers can also avoid the adverse effects on people's health, which is more green and healthy than the traditional edible starch film.

[0018] 4. The raw materials for preparing the taste film of the present application are widely available, the cost is low, the operation is simple, the film material is degradable, and the environment is not polluted. BRIEF DESCRIPTION OF DRAWINGS

At the same time, the intermolecular interaction and dilution of starch are enhanced by mono and diglycerides of fatty acids, which can improve the tensile strength and transparency of the taste film, and help the molding of the taste film. In addition, the edible starch and cassava starch are used as the main raw materials, and the high molecular chain characteristics of the cassava starch molecules (such as the linear structure of amylose and the branched structure of amylopectin) are used to insert between the edible starch molecular chains to weaken the hydrogen bond density, effectively improve the flexibility and ductility, so as to form a continuous film by gelatinization and interchain hydrogen bond crosslinking, so that the molding difficulty of the starch film is lower, and the film strength is effectively improved. The use of plasticizer can also be avoided.
