Abstract

Packaging is one of the most important parts in maintaining the quality of food product. The film of agarglycerol-chitosan has been prepared fromthe isolated agar of Gracilaria. The objective of this study is to investigate mechanical properties including the tensile strength, the young’s modulus, the elongation at break,the functional groups by FTIR and the water solubility. The film was prepared by mixing agar, glycerol (20 %) and chitosan (0 %, 1 %, 2 %, 3 % and 4 %) at 60 0C and 600 rpm. FTIR showed that the interaction occurred in the film agar-glycerol-chitosan was hydrogen bonding. From the result, the more chitosan added to the agar-glycerol-chitosan film, the higher the tensile strength, the elongation at break, the young’s modulus and the water solubulity.
