Mechanical and Barrier Properties Optimization of Carboxymethyl Chitosan-Gelatin-Based Edible Film Using Response Surface Methodology
Journal: Coatings
Year: 2023

Edible coatings have attracted the attention of researchers in recent years due to their degradability, safety, non-toxicity, low cost, good preservation effect, and other advantages. To prepare a new edible film with good mechanical and barrier properties, carboxymethyl chitosan (CMCS) and gelatin (GL) were selected as the film-forming matrix in this experiment, and glycerol, CaCl2, Tween-20, and ascorbic acid (AA) have been added as plasticizers, crosslinking agents, surfactants, and antioxida
