The influence of enzymatic cross‐linking on the rennet coagulation of Berridge substrate was investigated in the rennet gel samples prepared by three different methods using a microbial Tgase. Protein cross‐linking was carried out at each of three stages: before the addition of rennet, simultaneously with rennet and after the addition of rennet. The results showed that the cross‐linking of milk proteins before the addition of rennet inhibited the primary enzymatic phase of rennet coagulation. It was observed that enzymatic cross‐linking affected both the primary and the secondary phases of rennet coagulation. The most suitable application method was the addition of transglutaminase at the 5th minute after the addition of rennet.
