"Canola" is a combination of "Canadian" and "ola". The nutritional components of canola oil and rapeseed oil are quite different, and they belong to two different vegetable oils. ?
The main planting areas in the world are Canada, Australia, the United States and other regions, and Hulunbeier grassland in China also has planting areas; Canola, a double-low rapeseed, has strict international standards.
To distinguish it from rape, that is, less than 2% erucic acid and less than 30 micromoles of glucosinolates. If rape does not meet this standard, it cannot be called double-low rape.
