Preparation and characterization of edible film from the belitung taro starch (Xanthosoma sagitifolium) and chitosan

Abstract

Edible film can be used as packing material alternative that does not give negative impact to the environment since it uses cheap and renewable sources. Belitung taro starch (Xanthosoma sagitifolium) and chitosan are used as the ingredients in the making process of edible film with glycerol as the plasticizer. The characterizations of edible film includes thickness, tensile strength, maximum strain, Scanning Electron Microscopy (SEM), and Fourier Transform Infrared Spectroscopy (FT-IR). The obtained result was addition of chitosan 0.5% (PK1) is the best edible film if observed from tensile strength of 84.34 MPa and chitosan 1.5% (PK5) from maximum strain of 49.1%. SEM morphologic photograph shows the surface of the film that is homogeneous and without any fractures.
