Influence of glycerol and chitosan on tapioca starch-based edible film properties
The individual and interactive effects of glycerol and chitosan on tapioca starch-based edible film properties were investigated using response surface methodology. Tests were run on the polymeric matrices to determine film forming solution apparent viscosity, mechanical and dynamic-mechanical prope...
