Signs Atta / Whole Wheat Flour has gone bad
- Sour, musty, or rancid smell instead of a mild wheaty aroma.
- Clumping from absorbed moisture.
- Insects, webbing, or black specks; any visible mold.
Still good if
- Slightly faded aroma but no off smell — usable, though rotis may taste less fresh.
Discard immediately if
- Sour or rancid smell
- Any visible mold — discard the whole batch (mycotoxin risk)
- Insect infestation or webbing
Why guidance varies
Atta keeps the wheat germ and bran, whose natural oils oxidise and turn rancid faster than refined flour — and faster still in heat and humidity. Cold storage slows it sharply; the main hazards are rancidity, weevils, and (if damp) mold.
