Abstract


The objective of this research work was to follow the evolution of peroxide, anisidine, totox. iodine and acid values and refractive index during the oxidation of soybean oil using the Rancimat method. Various temperatures were used in this case (110°, 120°, 130° and 140°C) and the oxidation curves obtained through the Rancimat were compared with those obtained by the variation of the traditional values above mentioned, against the time. It was observed that the correlation coefficients were high for all methods (0,849<r<0,997) but the induction periods obtained with the Rancimat were generally higher than those obtained with the other analytical tests.
