After inoculation, flask samples were transferred to a water
bath that was connected to a CINAC (Cynetique d'acidificacion, Alliance
Instruments, Frepillon, France) system that allows for the continuous
measurement and recording of pH values, as well as the evaluation of
the acidification kinetics throughout the run. Batch fermentations
were performed at 42 °C up to a pH of 4.6, which was selected as the
condition for stopping fermentation. Afterward, fermented milk was
transferred to an ice bath and cooled down to 15 °C. The gelwas broken
using a stainless steel perforated diskwith up and down movements for
approximately 1 min. The productwas put in 80-mL sterile plastic cups,
and stored at 4 °C for 28 days.
