Freezing process and frozen storage
Total dough cylinders were placed in an industrial freezer
(Panem, France); the freezer produced air blast temperature at
40 C. The freezing rate was estimated to be about 0.39 C/
min. Temperature in the dough during freezing process was
recorded using a K type thermocouple (300 lm diameter Ahlborn
France) connected to an Almemo data logger (model 2290-8 V5
AMR). The thermocouples were calibrated using a reference thermometer
at ±0.1 C. At the end of freezing, the dough cylinders
were stored at 40 ± 1 C in the freezer (TT 151 Curtiss, France)
for 9 weeks.
