3.3. Lipid oxidation in yogurt
Lipid oxidation increased in each of the yogurt samples (Table 3) and
was significantly positively correlated (P b 0.001) with days 14, 21 and
28 of storage (Table 5). Yogurts containing AN80e (0.5%) and FV60e (0.5%)
exhibited significantly (P b 0.05) lower levels of lipid oxidation compared to the control and other yogurts, which may be attributed to
various antioxidant compounds present in the extracts. A previous
study (O'Sullivan et al., 2014) found that FV60e (0.25%) significantly reduced
the level of lipid oxidation in milk.
