Characteristics of Brassica napus (Argentine Canola) Expand

Center of Origin Reproduction Toxins Allergenicity

The species is native to India.

Canola flowers can self-pollinate, and they can also be cross-pollinated by insects and by wind.­

Brassica species can contain erucic acid and various glucosinolates, which can be toxic. However, commercial canola varieties have been bred to reduce the levels of these substances. Canola may contain elevated levels of tannins, which reduce the digestibility of seed protein, and sinapine, which is a bitter substance that can reduce the palatability of feeds made from canola meal.

­

Occupational exposure to pollen and seed flour have been associated with allergic reactions in humans. There are no known allergic reactions to canola oil.
