Abstract

The oxidative stability of bleached soybean and sunflower oils which were previously refined using NaOH and KOH at concentrations of 12, 14 and 16 Béo was studied in comparison with semirefined sunflower and crude soybean oils. Semirefined sunflower oil and crude soybean oil showed the highest stability. Oils previously refined using 12 Béo NaOH or KOH had an acceptable stability. Higher NaOH concentrations resulted in a decrease of stability.
