So what do you do with your powdered dairy products once you've opened the can? Simply use what you need, and then store the rest in a plastic freezer bag. Freezer bags are thicker than regular storage bags, so they help keep moisture out of your food.
Moisture can create lumps in your powdered milk and powdered butter, so be sure to seal the bags as tight as possible.
Just a note: Powdered eggs, Powdered cheese, and Powdered butter need to be kept in the refrigerator, however Powdered Milk and Buttermilk DO NOT need to be refrigerated.
The normal shelf life for powdered dairy products is 3 years, so continue to rotate them so you can be sure you always have a fresh supply on hand.
