This study was aimed to the effect of adding transglutaminase (TGase) on mechanical and reservation properties edible films manufactured from soybean meal protein isolate (SPI) whey isolate(WPI). The results showed an improvement in with increase WPI ratios. Thickness SPI amounted 0.097 mm decreased 0.096 for WPI: at a ratio 2:1, when TGase added 0.075 mm. While tensile strength increased 7.64 ...
