Yes, corn oil can go bad. Like most oils, it can become rancid over time, especially if it is not stored properly. This means it can develop an unpleasant smell and taste.
How to Tell If Corn Oil Has Gone Bad:
- Smell: If the oil has a strong, unpleasant odor, it is likely rancid.
- Appearance: The oil may become cloudy or darker in color.
- Taste: If the oil tastes bitter or metallic, it has likely gone rancid.
How to Store Corn Oil:
- Store in a cool, dark place.
- Keep the bottle tightly sealed.
- Avoid storing oil near heat sources.
How Long Does Corn Oil Last?
- Unopened corn oil: Can last for up to 1-2 years if stored properly.
- Opened corn oil: Can last for about 1 year in the pantry.
Important Note: While corn oil may be safe to use after its expiration date if it has been stored properly and doesn't show any signs of spoilage, it's best to err on the side of caution and discard any oil that has been stored for an extended period or shows signs of rancidity.
