Quantitative determination of chymosin activity by thrombelastography
An accurate and objective thrombelastographic procedure for the quantitative determination of chymosin in solution and in cheese whey is proposed. Linear relationships between coagulation time and the inverse of chymosin concentration in solution showed determination coefficients (r2) in the range 0·989-0·997. A satisfactory reproducibility was achieved, with 0·88% as mean coefficient of variation. Determination coefficients for linear relationships between coagulation time and the inverse of chymosin present in whey ranged from 0·995 to 0·998. Reproducibility of chymosin quantification in whey was high, with 0·98% as mean coefficient of variation. © 1993.
