Stabilized peanut butter past the expiration date
Unopened
FoodKeeper gives unopened stabilized peanut butter 6–9 months in the pantry or 12 months in the fridge, 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 3–4 months in the fridge or 2–3 months in the pantry from the day you open it.
How to keep stabilized peanut butter 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.
