During storage, supplemented LF-yogurts showed a significant
difference in the decrease in pH (Table 2) until day 14 and control
until the 21st, taking a longer time to reduce the pH. Yogurt D (1%)
showed the lowest pH values during storage (4.25), followed by the
others supplemented yogurts and then the control and showed a
significant difference (p < 0.05) in relation to the control in all evaluated times. In terms of lactic acid, as well as pH, supplemented
yogurts showed a significant (p < 0.05) increase during 14 days.
Differences mainly between control and D (1%) were observed over time.
