The values for Kd, t1/2 calculated and the decimal reduction time Dϑ are summarised in Table 3. As expected, the values for Kd, increased with increasing temperature (70–90 °C) while t1/2 and Dϑ decreased. The values for t1/2 obtained in skim milk were about 8–18 times higher than in SMUF, indicating a much better heat resistance in skim milk.
