The rapeseed plant usually blooms in the summer and is famous for its golden-yellow flowers. Its oil — known both as rapeseed and canola oil — is widely used for cooking, baking, and food processing. Industrial rapeseed oil is used in the automotive and chemical industries, while canola oil is used for cooking. The difference between the two is the concentration of erucic acid. Canola oil can only contain less than 2% erucic acid, while rapeseed oil can contain more erucic acid.
