Oilseed Rape (Brassica napus)
Rapeseed oil is one of the oldest vegetable oils, but historically used in limited quantities due to high levels of erucic acid, which is damaging to cardiac muscle of animals, and glucosinolates, which made it less nutritious in animal feed. Rapeseed oil can contain up to 54% erucic acid. Food-grade canola oil derived from rapeseed cultivars, also known as rapeseed 00 oil, low erucic acid rapeseed oil, LEAR oil, and rapeseed canola-equivalent oil, has been generally recognized as safe by the United States Food and Drug Administration. Canola oil is limited by government regulation to a maximum of 2% erucic acid by weight in the USA and 5% in the EU, with special regulations for infant food. These low levels of erucic acid are not believed to cause harm in human neonates.
