Canola Oil: what it is and where it hides
Short answer
Canola oil is a refined seed oil pressed from rapeseed bred to be low in erucic acid, then typically extracted with hexane, degummed, bleached and deodorised before bottling.
Also written as
On an ingredient list this oil can appear as rapeseed oil, low erucic acid rapeseed oil, LEAR oil. Olive Detective normalises every one of those to a single flag, so a label in another language does not slip past.
Where you run into it
- Packaged baked goods, crackers and cookies
- Salad dressings, mayonnaise and dips
- Restaurant fryers and most 'vegetable oil' blends
- Roasted nuts and snack mixes
Why people avoid it
The seed-oil-free community avoids canola for two reasons: it is high in omega-6 linoleic acid relative to omega-3, and the industrial refining it goes through (high-heat deodorising, solvent extraction) is the opposite of the whole-food processing they are trying to eat toward.
What people use instead
- Extra-virgin olive oil for dressings and low-heat cooking
- Avocado oil for higher-heat cooking
- Butter, ghee, tallow or coconut oil for baking and frying
How the app flags it
Scanning a barcode matches the product against Open Food Facts and reads its parsed ingredient taxonomy, so canola oil is detected by canonical tag rather than by string-matching English text. If the barcode is not in the database, the camera reads the ingredients panel instead. The flag feeds the personalised “For You” score only as heavily as you ask it to — seed oils are one preference among several, not the whole verdict.
