迷迭香天然抗氧化剂的应用研究

摘要

The application of rosemary as a natural antioxidant in walnut oil was researched. The antioxi-dant effects of rosemary and TBHQ were compared by antioxidant experiment, storage experiment and cooking experiment. The results showed that rosemary had better antioxidant effect and its antioxidant effect in walnut oil increased with the dosage increasing. 0. 02% rosemary and 0. 02% TBHQ exhibited similar antioxidant activity, which could delay the rancidity and formation of trans fatty acids of walnut oil.%以核桃油为实验基油，研究了迷迭香天然抗氧化剂的应用。通过抗氧化实验、储藏实验和烹调实验，比较了迷迭香抗氧化剂和TBHQ的抗氧化效果。结果表明，迷迭香抗氧化剂具有较佳的抗氧化效果，在核桃油中随着迷迭香抗氧化剂添加量的增大抗氧化效果依次增强，0．02%迷迭香抗氧化剂与0．02% TBHQ有相似的抗氧化能力，可对核桃油酸败和反式脂肪酸形成起到延缓作用。
