You can. All you really need to do is keep it away from moisture and dry. Once damp, it can spoil. I use separate containers that are airtight that I keep my flour, sugar, cornmeal, corn starch, Rice, instant mashed potatoes, baking powder and baking soda in. If you freeze the powder, you still need to store inside an airtight container or else the powder will absorb the odors that are common in most freezers and taste bad when used in recipes.
