dc.description.abstract | Edible film is an environmental friendly packaging derived from biopolymer. The film is edible or could be easily degraded as it disposed to environment. In this study the film was composed of carrageenan, glycerol, cellulose, and some compositions of sweet potatoes flour. The best film properties produced was tat containing 5% flour. The film was transparent and flexible. Thermal analysis showed that the film was degraded endothermically at 36.27 μV and exothermicaly at 25.96 μV, 39.02 μV, and 75.65 μV. Repeatedly exothermic peaks were due to inhomogeneous solution during preparation. Infrared analysis proved no chemical interaction occured during film formation, could be due to physically interaction. The infrared spectra similar patterns for all compositions of the film. | en |
