Can you freeze flour?

Yes, it is acceptable to freeze flour. For long-term storage, About.com recommends freezing flour in a strong, food-grade plastic bag or a food grade container with a lid. Properly stored, flour generally stays fresh for two years.

For normal storage, flour should be placed in an airtight container in an area where the temperature remains 75 degrees Fahrenheit or cooler. Eating Well states that whole-wheat flour tends to go rancid more quickly. Therefore, it should be stored in either the refrigerator or the freezer. Flour should not be stored next to any food with a strong odor, as it may pick up that flavor.
