The overall objective of this research was to study the effect of recombinant rhizopus chinensis lipase (RCL) and transglutaminase (TG) at optimum amount on frozen dough properties. First response surface central composite experimental analysis method was used to obtain the optimum amount of RCL and TG on dough with different frozen storage. Based on the optimum amount of RCL and TG, we studied the effect of RCL and TG on dough proofing time, bread specific volume, crumb cell structure parameters, and senso...
