The pasteurisation value (P value) was calculated for each
production variant. Bacillus coagulans was chosen as reference
organism with Tref ¼ 93.3 C and z ¼ 8.9 (Brown, 1991). During
processing, temperature was monitored at 30 s and 120 s intervals
for heating-up and cooking (final process temperature), respectively,
and P values were calculated according to Eq. (1).
