Natural extracts are investigated as plasticizers of starch–glycerol biobased films for food
coating applications. For this purpose, films with cassava starch, glycerol, and distilled water
with and without green tea or basil extracts are obtained by solvent casting. The plasticizing
effect of the extracts is confirmed from the films crystalline structure, thermal degradation
behavior, glass transition temperature, and tensile properties. Increased mobility of starch
chains is the result of a strong interaction between extract components and starch …
