Abstract:  Antioxidative effect of carotenoids on the methylene blue sensitized photoxidation of soybean oil and rapeseed oil was investigated.The results showed that each of the three carotenoids remarkably protected lipids against photoxidation .The antioxidative activity increased with increasing carotenoids concentration.The antioxidative effect also corresponds to the number of conjugated double bonds of carotenoids.

Key words: Carotenoids, Photosensitized oxidation
