Corn Oil: what it is and where it hides
Short answer
Corn oil is a refined seed oil extracted from the germ of corn kernels, usually as a by-product of corn milling, and is high in omega-6 linoleic acid.
Also written as
On an ingredient list this oil can appear as maize oil, corn germ 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
- Deep fryers in restaurants and fast food
- Margarine and shortening
- Snack foods, popcorn and corn chips
- Mayonnaise and dressings
Why people avoid it
Corn oil is a refining by-product rather than a food pressed for its own sake, and it carries the same omega-6 profile as the other industrial seed oils — both reasons the movement avoids it.
What people use instead
- Tallow or lard for frying
- Olive oil for finishing
- Butter or ghee for baking
How the app flags it
Scanning a barcode matches the product against Open Food Facts and reads its parsed ingredient taxonomy, so corn 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.
