Differences between canola oil and rapeseed oil
Both rapeseed oil and canola oil come from the same plant, rapeseed, rape or canola (Brassica napus). The canola oil was initially called “double zero” variety.
This first variety was genetically modified from rapeseed, due to its high content of erucid acid and glucosinates, which were reduced to values not higher than 2% and 3mg / g, respectively, because they are toxic for human consumption.
Thanks to these modifications, it became canola oil, which we know today, that is, in a vegetable oil suitable for human consumption.
Characteristics of rapeseed oil
Rapeseed oil (in its canola variety) is obtained from the rapeseed seeds, the extraction method and solvents are used for a greater production of oil and can be subjected to refining.
Its content in fatty acids is similar to that of olive oil, but with a higher content of linoleic acid and less of saturated fatty acids.
In fact, it is the oil that contains the least amount of saturated fatty acids, while it is the largest contributor of oleic acid.
Therefore, its composition is mostly monounsaturated due to its high oleic acid content, with levels of between 50 and 60% of its content and also in omega 6 and omega 3, since, together with walnut oil, it is the Higher content has linolenic acid.
But its biggest difference is its content in a fatty acid called erucic, which is toxic to our body and affects the heart specifically.
