late-coagulating samples). The curd-firming process
of these samples was very slow and inefficient: 14/87
samples did not reach the 20-mm oscillation amplitude
within the 90 min of the prolonged test, and only a few
samples would have reached this threshold within the
standard duration of 30 min. In addition, the average
of the few k20 values available for these samples was
more than twice that of the converged samples (Table
1). We were able to measure the a30 values of only the
37/87 samples that coagulated within 30 min, and their
average value (12.1 mm) was very low (Table 1).
