During
24 weeks of storage, pH and titratable acidity of ice
cream fell within 6.65–6.54 and 0.21–0.16 respectively. No
statistically significant changes in the pH and titratable
acidity of goat’s milk ice cream were observed during storage
regardless of the different packaging. Alamprese et al.
(2002) observed a similar non significant trend in the acidity
of ice cream across 12 weeks of storage, as did Kudelka
(2005), whom reported that packaging materials – polypropylene,
polystyrene and polyethylene – had no influence on
the acidity of probiotic yogurts.
