Storage tips
- Keep textured soy protein sealed in a cool, dry cupboard after opening to hit the window above. It does not need refrigerating.
- Keep soy flour and textured soy protein airtight in a cool, dark cupboard. Full-fat soy flour carries enough oil to go rancid, so refrigerating it extends the window well past the pantry figure.
How can you tell if textured soy protein has gone bad?
- A sour or off smell rather than the mild, neutral one it had fresh.
- In dry soy products: a rancid or paint-like smell from the fat in the flour, clumping from damp, or any sign of pantry pests.

Shelf-life windows come from the USDA FoodKeeper, published by the USDA Food Safety and Inspection Service (public domain); we vendor the FSIS FoodKeeper dataset and refresh it in place. These are quality estimates, not food-safety determinations or guarantees: actual condition depends on storage and handling, and harmful bacteria may not have obvious signs.
