Effect of temperature and oil composition on the ability of phenolic acids to protect naturally present alfa-tocopherol during the heating of plant oils
Original language description
The ability of phenolic acids (ferulic, gallic, protocatechuic, and sinapic; 600 mg/kg) to protect naturally present alfa-tocopherol was tested during the heating of sunflower oil on a hot plate set at 120, 150, 180, 210, or 240°C, and during the heatingof rapeseed, olive and soybean oils on a hot plate set at 180°C. In all the studied conditions, alfa -tocopherol was significantly protected only by gallic acid. This phenolic acid prolonged the half-life of alfa -tocopherol (calculated as the time needed for the alfa -tocopherol content to decrease to 50% of the original value) typically two- to four-fold. Hence the ability of phenolic acids to protect alfa -tocopherol in bulk oils does not markedly depend on the experimental conditions as is seen inantioxidant activity, i.e. in the ability of antioxidants to protect fatty acids.
