Research Progress on Application of Natural Antioxidant Rosemary Extract in Edible Vegetable Oil

More and more attention has been paid to the safety and nutrition of edible vegetable oil. Maintaining the nutritional quality and stability of edible vegetable oil has become a key issue in the oil industry. Rosemary extract, as a natural antioxidant, has good oxidation resistance, which could inhibit the oxidative deterioration of oil and prolong the storage time for keeping the good sensory and nutritional quality of oil. Also, it shows better stability in high temperature environments. The oil is taken mainly through hot processing in China, so the natural nontoxic, efficient and heat-resistant antioxidant is desired for Chinese edible oils. In this paper, the application research progress of rosemary extract in edible vegetable oil was reviewed, providing theoretical reference for the antioxidant research of rosemary extract in oil.
