Rapeseed oil is widely used in the food industry, especially after palm oil has been banned.
Origin of rapeseed oil
Rapeseed oil is obtained from rapeseed seeds, a plant of the Brassicaceae family. In the past, this oil was considered toxic, because it did not undergo accurate refining processes and contained high percentages of erucic acid, a monounsaturated fat that is difficult to metabolize, which accumulates in the body mainly by the liver and harmful to the heart.
Subsequent regulations for food control have established that the level of erucic acid must respect the 5% ceiling for foods intended for adults and 1% for those intended for children.

As already mentioned, rapeseed oil is extracted from the seeds of Brassica Napus Oleifera, the rapeseed. This oil has been extensively studied and researchers have succeeded in obtaining a variety of rapeseed with low erucic acid content tending to zero, called Canadian Brassica or Canola from Canadian Oil Low Acid, therefore completely harmless to health.
Rapeseed is grown in many European countries, especially in France, Germany, Belgium, Holland and Italy. The residues of the extraction from the seeds are used to make rapeseed meal, used in animal feed.
