Influence factors of carotenoid content in rapeseed and its antioxidant effect
Carotenoid is fat-soluble substance and is abundant in rapeseed oil.In order to improve the nutritional value and oxidative stability of rapeseed oil,the influence factors of carotenoid content in rapeseed oil were analyzed,and the antioxidant effect of carotenoids was reviewed.Rapeseed varieties and processing technology can affect the carotenoid content in rapeseed oil.While the increase of carotenoid content in rapeseed oil can enhance the oxidative stability of rapeseed oil.The carotenoid content in rapeseed oil can be improved by adopting transgenic technology to cultivate high carotenoid content rapeseed varieties,pretreating the rapeseed with baking,microwave heat treatment and not peeling,and moderately refining the crude oil.
