Acidification trend in yogurt were measured during yogurt
fermentation according to the method described using a FACS (Fermentation Acquisition
and Control System) installed in a Forma Scientific (OH, US)
programmable incubator. The buffering capacity of the different
blends was estimated by acid titration and pH measurements using a
pH meter (Accumet AP61, Fisher Scientific Inc, ON, Canada) and a
50 ml digital Burette .
