Transglutaminase (EC 188.8.131.52) catalyses an acyl-transfer reaction in which the γ-carboxamide group of peptide-bound glutaminyl residues are the acyl donors. In this research is compare the influence of transglutaminase enzyme dosage on the animal protein which is duck meat and vegetable protein which is analog meat from TSP and soy powder. The sample was tested by some instrument analysis namely pH meter, Texture Profile Analyzer (TPA). Then, the sample was analized its nutrition by Proximate test. By these tests, it could be obtained the optimum of amount transgluminase dosage in animal or vegetable protein source. The experimental variations is the enzyme dosage. The enzyme dosage for animal protein source are 0.0%; 0.3%; 0.6% and 1%, while vegetable protein source are 0.0%; 0.5%; 1,0%; 1.5% and 2% with the duration of 24 h incubation in 4°C. The result showed that the characteristic of each sample observed, increased dosage of transglutaminase enzyme affects the texture of sample as evedenced by TPA. In animal protein the optimum enzyme used is 0,6 %, while in vegetable protein the optimum enzyme is 1,5% as evedenced by TPA and acidity test level.
