Effect of glycerol on the physicochemical properties of cereal starch films

The physical properties of corn, wheat and rice starch edible films with different level of glycerol were evaluated. Starch films exhibited an apparent endothermic peak in the range of 151–199°C with corn starch film with 1.6% glycerol having a relatively lower To and higher Tp. X-ray diffraction sp...
