To evaluate their behavior during the frying, the formulated oils
were subjected to heating at constant temperature and without
food. These oils were heated separately in an electric fryer (Ufesa,
EEC) at 180 ◦C (±2 ◦C) for 6 h/day for 5 consecutive days. At the end
of each essay, 60 ml of oil is taken for physicochemical characterization
and evaluation of the fatty acid composition. The samples
were stored at 4 ◦C until analysis
