Triplicate measurements were performed.
The water holding capacities of yoghurts were measured
by centrifuging 50 g of yoghurt sample at 500 g at 4 C for 20 min
(SL 16R, Thermo Scientific, Waltham, MA, USA). After the centrifugation,
the separated whey was weighed and given as a percentage
(w/w) of the yoghurt sample. Duplicate measurements
were performed for each yoghurt sample.
