Colza Oil
Modern food-grade colza/rapeseed (canola) oil must contain less than 2% erucic acid. Traditional high-erucic-acid colza oil was associated with cardiac lipidosis in animals, leading to development of canola.
What it is
Colza oil is the historical name for rapeseed oil (Brassica napus); modern food-grade rapeseed oil with low erucic acid is known as canola.
Cooking oil and fat ingredient.
Why it's flagged
- historical high-erucic-acid concerns (now regulated)
- highly refined product
What regulators actually say
"Low erucic acid rapeseed oil is the edible oil obtained from the seeds of any of the Brassica napus L., Brassica campestris L., or Brassica juncea L. species... not more than 2 percent erucic acid."
"The CONTAM Panel established a TWI of 7 mg/kg bw for erucic acid."
