The time taken for LF-yogurts to
reach pH 4.6 was affected by the addition of POE (Fig. 1), and the
multiplication of S. thermophilus and L. bulgaricus was slightly
greater in yogurts supplemented (Table 2), specially in LF-yogurts B,
C and D, which could have been the reason for the shorter incubation
time needed to reach pH 4.6 for these samples.
