The oxidative stability of vegetable oils has been introduced as a critical factor that affects on its quality, shelf life, and nutritional value. In this study, the Rancimat method was analyzed for investigation and comparing the oxidative stability of crude and refined vegetable oils. The induction period, representing the time taken for significant oxidative degradation to occur, has been used as a key parameter to evaluate the oxidative stability. The oxidative stability of different types of vegetable oils, including sunflower, rapeseed, soybean, and cottonseed oil, was studied at various stages of processing: water degummed and neutralized oil. The induction period (IP) and protection factor (PF) were used to assess the oils resistance to oxidation. The data showed that crude oil had the highest oxidative stability, with a PF of 1.89 for rapeseed, 2.13 sunflower, 2.3 for soybean and 1.95 for cottonseed oils, compared to water degummed oil. Neutralized oil showed improved oxidative stability, with a PF of 1.16 for rapeseed oil and 1.57 for soybean oil, but reduced stability with a PF of 0.85 for cottonseed oil comparing with degummed oils. Refining processes, such as neutralization and degumming, were shown to pose a potential decrease in oxidative stability due to the removal of minor components present in the crude oil.
