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.
