Fermented milk post-acidification was determined in triplicate 1 day after the fermentation was complete and after 14 and 28 daystorage at 4 °C using a pHmeter model PG1800 (Gehaka, São Paulo, Brazil). The susceptibility of fermented milk to syneresis was determined using a drainage method as described by Hassan, Frank, Schmidt, and Shalab (1996).
