Rapeseed contains large amounts of oil. Oil is mainly composed of fat, while fat is composed of fatty acids and glycerol synthesis. There are many types of fatty acids in vegetable oils, mainly stearic acid, oleic acid, linoleic acid, linoleic acid, eicosanoic acid, erucic acid and eicosanoic acid. Erucic acid content in the general rape is higher, accounting for about 28.2-55.1% of the lipid acid. Oleic acid and linoleic acid can make blood vessels soften and increase elasticity, which is beneficial to human health. However, erucic acid and linoleic acid are harmful to human health. It is reported that animal experiments with high erucic acid oil, hair
