Sunflower oil past the expiration date
Best-by and sell-by
FoodKeeper gives unopened sunflower oil 1 year in the pantry, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Past the date
Sunflower oil past its best-by date is usually safe if stored well; check smell, look and taste before using.
How to keep sunflower oil fresh longer
- Keep in a cool, dark place, tightly closed, away from heat.
- Refrigerating nuts, seeds and nut oils extends shelf life significantly.
- Smell before using; rancidity is a quality problem you can detect.
