Alginate/aloe vera films reinforced with tragacanth gum.

The objective of present study was to investigate the effect of incorporation of varying concentrations (2% to 14%) of Tragacanth gum (TG) to alginate/aloe vera composite films to enhance their functional properties. The resulting films were investigated for their mechanical, barrier, optical properties and biodegradability. The WVP, swelling capacity and thickness of films increased significantly by the addition of TG while film solubility was dropped at higher concentration of TG.
