The effects of glycerol and sorbitol on the mechanical and thermal properties and water adsorption capacity of cassava starch films were studied. Films with different water activities (0.11 to 0.90) were tested and when these films were plasticized with any glycerol or sorbitol content at a water activity (aw) ¡Ü 0.58, the plasticized films adsorbed less water than the unplasticized ones. Glycerol films, under all aw values, presented higher equilibrium moisture contents than sorbitol ones. Only with plasticizer contents above 15 g.100 g¨C1 starch could a decrease in the glass transition temperature (Tg) be observed in relation to the unplasticized samples, which presented a Tg of 52.77 ¡ãC. In contrast to glycerol, sorbitol exerted an antiplasticizing effect that could be detected by tensile stress tests, and both plasticizers had an antiplasticizing effect on film strain. The results indicated that the presence of small amounts of the plasticizers employed (<15 g.100 g¨C1 starch) was able to exert an antiplasticing effect in systems with low water contents.w) ¡Ü 0.58, the plasticized films adsorbed less water than the unplasticized ones.
