Highlights Blends of selected cold pressed oils with sunflower oil (SF) were formulated. Oxidative stability (OS) and antiradical properties of blends stored for 8 days at 60 °C were studied. OS of blends were better than SF due to changes in fatty acid and tocols profile. Blending of SF with cold pressed oils results in healthy oils with improved OS.
