| dc.description.abstract | Edible films is one of biodegradable packaging that can be consumed with foodstuffs. Tapioca starch edible film plasticized by glycerol and combined with agar is one of alternative as a food packaging material. Films are made from food grade materials, so they are safe to be consumed. Tapioca starch-glycerol composition is 8:2 added with various concentration of agar 0, 1, 2, 3, and 4%. Films produced were analyzed for tensile strength, density, water vapor permeability, fungtional group, morphology, and application on fruit. Film added with 4% agar is the optimum composition with 4.4156 MPa tensile strength and the percentage elongation of 13.58%. Water vapor permeability of that edible films is 1.2780 x 10-9 g s-1 m-1 Pa-1. Morphology analysis shows that there are granules in the film, it means that film surface is not homogeneous. Functional group analysis shows that the process of film making happened physically. Testing on strawberry shows that edible film can stand water vapor permeability. | en |
