The glycerol-plasticized films were significantly
less resistant (p < 0.05) and more extendible (p < 0.05) than the
sorbitol-plasticized films, suggesting that glycerol could be a more
effective plasticizer in kefiran films. However, increasing glycerol
content did not significantly affect TS of the formed films (p > 0.05)
(Fig. 2).
