Abstract: The aim of the present study was to evaluate the effect of 5 species of chymosin with different concentrations on the dynamics of the traits measured by mechanical lactodynamograph, characterizing the coagulation ability of buffalo milk. The coagulation properties of buffalo milk were evaluated on 420 milk samples taken during morning milking from whole milk. Five enzymes (MAXIREN 600, FROMASE 750, MAHIREN XDS, MAXIREN 180 and MAXIREN PREM P) were tested with 4 concentrations each and one control group with a standard, recommended by the manufacturer of the biosensor – mechanical lactodynamometer chymosin (Polo Trade – Computerized Renneting Meter, Italy). The effect of the concentration of each enzyme was determined by examining 20 milk samples. The use of enzymes at various concentrations resulted in substantial variation in the magnitude and direction of changes. Different chymosins with different concentrations actively affect the curd firmness. The shorter coagulation time will provide sufficient time for the curd firming time and its curd firmness. Over 50% of milk samples coagulate by 6 minutes. The effects of enzymes and their different concentrations on measurement were in different groups, which in our opinion was a good prerequisite for using the obtained data for modelling of the measurement process.
