Does coconut flour go bad?
Yes. The fridge time above is the window USDA gives for good quality; after it, coconut flour may still be safe for a short while but quality drops and spoilage signs start. The date on the package is the maker's quality promise; the times here count from purchase unless marked "from the package date".
Two numbers to keep in mind: a fridge at 40 F (4 C) or below, and no more than 2 hours at room temperature (1 hour above 90 F / 32 C) for anything perishable.
How to tell coconut flour has gone bad
General signs for baked goods: baking and cooking, the group USDA lists coconut flour under.
- Small moths, beetles or larvae in the flour or grains
- Clumping or hardening from moisture getting into the bag
- Sharp, crayon-like or paint-like smell from oil
- Baking powder that no longer fizzes when mixed with water
- Chocolate chips with a dull grey bloom or waxy smell
