Does flour spoil?


Much to my chagrin, while poking around my pantry I found two containers with nearly full bags KAF flour, one all purpose, one white whole wheat. Both must be several years old, both have been kept in air tight containers. Would these still be usable or should I toss and replace?

Hi Nancy,
It's not that the flour is going to be harmful, but it won't perform very well if you do use it. It's a bit of a waste of your other good ingredients to use very old flour and risk poor results. We'd say "chuck it".

Thanks, now I won't feel bad about throwing it away.

I wonder if you can be sure it won't be harmful, in light of the toxins found in some old mixes (reported in the past year). Maybe it's other ingredients in the mixes that caused the problem, but I agree- "chuck it". Also, if it's whole grain, it may get rancid.
