After talking about it as a possible biofuel, a sort of ecological petrol, rapeseed oil has returned to the fore in recent times as a slimming oil, a resource of omega3, omega6, in short, of good fatty acids, and therefore an oil that activates the metabolism and reduces cardiovascular risks such as canola oil, a kind of Canadian derivative also from rapeseed. How much is it true?
Rapeseed is a plant from which an oil is obtained which is widely used in industry, even in the food industry: industrial oil for lubricating purposes has a high content of erucic acid, a carcinogenic substance; the food one, on the other hand, has lower levels of erucic acid, but in Italy it is not found and has a higher cost, typically, regular rapeseed oil, and it’s called canola oil. An economic quality is however present as a frying oil in catering and is one of the vegetable oils of margarines. Already here begins the first confusion: is it always canola oil? On the other hand, abroad, for example in Germany, canola oil with low erucic acid costs more and is considered one of the richest and therefore healthiest vegetable oils. So it shouldn’t be the same as margarines. However, this article does not speak well of this expensive “sister” of rapeseed oil either . I would avoid buying it in the absence of precise information on both rapeseed oil processing and erucic acid levels
