Natural SilibininLinoleate: A Protective Antioxidant in Edible Vegetable Oils

This study evaluated the potential of silibinin linoleate (SL), a natural derivative of silibinin, as an antioxidant to improve the thermal stability of sunflower oil (SF). SL was synthesized through green technology by enzymatic esterification, using mild reaction conditions. SL was added to high-oleic SF samples at three concentrations (200, 400, and 600 ppm), and the oils were subjected to heating at 180 ◦C for 4 and 8 h. Oxidative stability, fatty acid composition, and nutritional indices...
