Amongst the long-chain unsaturated fatty acids, oleic acid
content was the highest in all samples. During storage, the amount
of oleic acid in the control sample was measured at between 22.88
and 22.04%. In contrast, the content in probiotic butter samples was
lower than in the control sample (Fig. 3). Yilmaz-Ersan (2013)
found that oleic acid values were higher in cream fermented with
B. lactis than in cream fermented with Lb. acidophilus and Lb.
rhamnosus. The linoleic acid level ranged from 0.50% to 0.74%
during storage. However, the linoleic acid level in sample B (0.57%)
was lower than in sample C (0.73%) at end of storage (P < 0.05).
