Sažetak
The influence of agronomical factors (two growing areas and four harvest periods) and storage conditions of virgin olive oils (room temperature, +4 and −20 °C) on tocopherols was investigated on two cultivars having significantly different tocopherol content (Oblica 269–443 mg/kg, Leccino 403–784 mg/kg). α-Tocopherol accounted for 97 % of total tocopherols and its content decreased during ripening of both cultivars. In a warmer growing area both cultivars gained a higher γ-tocopherol content while only Leccino showed a higher content of α-tocopherol. After 12 months of storage α-tocopherol content decreased by up to 27 %. Lower storage temperatures did not always contribute to the higher stability of α-tocopherol compared to room temperature.
