Canola refers to special type of oil seed mustard varieties bred for human consumption. The main characteristic of these varieties is that the

A

seeds have very high oil content

B

oil is rich in unsaturated fatty acids

C

oil has long shelf life

D

oil has very low Erucic acid content

Correct Answer: Option D

Explanation

1. Canola refers to specific varieties of rapeseed (oil seed mustard family) that have been bred, primarily in Canada, to be safe for human consumption. 2. Traditional rapeseed oil contained high levels of Erucic acid, which raised health concerns, and glucosinolates, which affected animal feed quality. 3. The *main characteristic* that defines Canola and makes it suitable for consumption is its very low Erucic acid content (D) – typically less than 2% – achieved through selective breeding. 4. While Canola oil also has favorable properties like high unsaturated fatty acids (B) and good oil content (A), the low erucic acid level is its defining feature distinguishing it from traditional industrial rapeseed.
