n the study, fatty acid compositions, bioactive and antimicrobial properties of fixed oil obtained from blue and white poppy (Papaver somniforum) seeds were examined. The major components found in the composition of samples were linoleic (69.2-73.2%), oleic (13.5-17.4%) and palmitic acid (8.8-8.9%). The total phenolic content was determined as 659.5±2.12 and 275.5±2.12 mg GAE/kg in blue and white poppy seed oil (BPSO and WPSO), respectively. According to DPPH and ABTS+ methods, the antioxidant activities were 40.35±0.14 and 41.09±0.58% for BPSO and 40.86±1.25 and 41.95±1.46% for WPSO, respectively. In the context of this study, antimicrobial effects of oil samples were determined for the first time on bacteria, important in food microbiology. The most sensitive microorganisms to BPSO were E. coli and L. monocytogenes. WPSO was shown similar level of antimicrobial effect on microorganisms except B. subtilis and S. aureus. Results showed that poppy seed oils have the potential to be used as natural antioxidant and antimicrobial products.
