How should whole wheat flour be stored?
Whole wheat flour is ground from the entire wheat kernel, which includes the bran, germ and endosperm. The keeping quality of whole wheat flour is limited due to the fat contained in the germ. Over time the fat becomes rancid, thus effecting the quality and flavor of the whole wheat flour. Unopened whole wheat flour can be stored on the shelf in a cool place for three months. Once opened, store in an air-tight container in the refrigerator or freezer up to three months.
