EFFECT OF ROSEMARY EXTRACT ON THERMAL STABILITY OF SUNFLOWER OIL

The purpose of this study was to evaluate the effect of rosemary extract (Rosemarinus officinalis L.) on thermal stability of sunflower oil. Samples of sunflower oil and sunflower oil containing 0.1% rosemary extract were subjected to three successive cycles of thermal heating at burning point for 8...
