i was watching a show today that mentioned that flour has a shelf life of one year, I store mine in the freezer to prevent bugs and other icky stuff from getting into it. Does this extend the shelf life or shorten it? And on that same subject I also store my spices in the freezer as well, I do find that this method does extend the life of spices that are not used that often.
Any bugs in flour came in the package with the flour. Freezing the flour kills the larva so they never grow to worms. Freezing will keep the flour fresh for longer. I've never heard of a shelf life for flour.
Spices will keep longer in the freezer too.
