Cooking spray past the expiration date
Unopened
FoodKeeper gives unopened cooking spray 2 years 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.
Opened
Once opened, the printed date no longer applies. Count 1 year in the pantry from the day you open it.
How to keep cooking spray 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.
