Abstract
Oxidative stability and flavor of sesame oil blended with canola oil (Ca), corn oil (Co), and soybean oil (Sb) at ratios of 90 : 10, 70 : 30, and 50 : 50 (w/w), respectively, were evaluated. Oxidative stability of sesame oil increased with the addition of vegetable oils (10, 30, and 50% of Ca and Co, and 10% of Sb). Pyrazines, pyrroles, pyridines, and thiazoles, good contributors to the characteristic flavor of sesame oil, were also found in sesame oil blended with vegetable oil. The sensory evaluation showed that no difference was observed between sesame oil and sesame oil blended with 10% of Ca, Co or Sb, which showed higher oxidative stability.
