Preparation and properties of arenga starch-chitosan based edible film

The main objective of this research was to prepare for edible film on the basis of arenga starch-chitosan. Carboxymethyl cellulose (CMC) was added to the blend and glycerol was used as a plasticizer. The tensile strength and water uptake of the film decreased with the increasing of glycerol content in the blend. Contrary, increasing glycerol content in the blend enhanced the elongation and swelling area of the film. The film C1, which has 6% of glycerol in the blend has a tensile strength of 124 KPa, elongation of 6.55%, swelling area of 21% and water uptake of 48%. The film C2, which has 10% of glycerol in the blend has a tensile strength of 58 KPa, elongation of 8.35%, swelling area of 32% and water uptake of 5%.
