Evaluation of Bioactive Compounds and Antioxidant Activity of Refined Vegetable Oils

Abstract

The objectives of this study were to evaluate the refined soybean, canola, corn and sunflower oils different brands and quantify the bioactive compounds and investigate the antioxidant activity of such oils. Corn oil showed higher content of phenolic compounds, while soybean oil obtained higher of total carotenoid content. For all oil, the highest total phytosterol content was obtained for brand M2. The γ-tocopherol was the predominant tocol in soybean oil. Refined soybean and corn oils showed greater effectiveness in DPPH●, FRAP, and β-carotene/linoleic acid trials. It can be considered that these oils are of high quality, presenting bioactive compounds and antioxidant activity through the methods used.
