Abstract: Transglutaminase concentration, pH, temperature and reaction period were selected to study the gelling capabilityof proteins including SPI, Casein, WPC, Egg White and Gelatin in this paper. The results showed that the great improvement ofgelling capability could be achieved when transglutaminas concentration was10~40U/g.pro, temperature 4~60℃, pH6~7 andreaction period 50~300min.

Key words: Transglutaminase, protein, gel, hardness
