Common questions
How long does coconut flour last in the fridge?
9–12 months in the refrigerator at 40°F (4°C) or below, according to USDA FoodKeeper data.
Can you freeze coconut flour?
Yes. Frozen at 0°F (−18°C), coconut flour keeps best quality for 9–12 months. Frozen food stays safe indefinitely; the time is for taste and texture.
How can I tell if coconut flour has gone bad?
Throw it out if you see mold, a slimy texture, an off smell or an odd color. For anything perishable, go by the storage time rather than smell: bacteria that cause food poisoning don't usually change how food looks or smells.
