Characteristics of transglutaminase:
Wide ph stability
Although the optimum ph of crude TGase is 6.0, it also functions with high activity in the wide range of ph 5.0 to 8.0.
on account of this wide ph range, a variety of applications can be effective in various food processes, regardless of food
type.
High thermal-stability
The optimum temperature of TGase is about 50. It also has high activity in the range of 45-55. A major advantage of TGase is that it becomes inactive when the internal temperature of food is at 75 or more
in normal foods.
Strong binding force
The covaient bond cataiyzed by TGase is hard to rupture under the conditions of non-enzymic reactions. Once the minced meat which was treated by TGase is shaped, the shape is kept, even though it is
frozen or sliced or cooked.
