Effects of processing on the oxidative stability

Abstract. The stability parameters of 22 samples of soybean oil produced in Mexico were determined. Samples were analyzed for moisture, color, free fatty acids, peroxide value, p-anisidine value, fatty acid profile, metals, flavor, and Rancimat test for oxidative stability.Results obtained were compared with the stability parameters of soybean oil sproduced in the United States and Costa Rica.
