Fromase 15 TL (Gist-Brocades nv, Delft, The Netherlands) was used as the coagulating enzyme. To determine the accuracy of the Yc measurement, Yc was measured for a sample in both dry and wet states. The dry curd was tested according to Melilli et al. (2002)), whose procedure was modified by weighing the wet curd after centrifugation and drying it overnight in an oven at 100°C. The curd sample was not transferred to another container for drying, as suggested by Meililli et al. (2002), but was left in the centrifugation tube to prevent any possible loss of curd during transfer of the centrifuged curd pellet. The correlation between Yc based on wet curd vs. dry curd is presented in Figure 1; the regression coefficient was 0.96.
