Expiration & Storage Tips
When does nonfat powdered milk expire?
Nonfat powdered milk can last anywhere from 2 to 5 years unopened, sitting in your pantry. This expiration date may vary depending on the brand or the packaging, but the general rule of thumb is that it can last quite long if stored correctly. Once opened, you can expect your nonfat powdered milk to retain its quality for about 18 months. While it won't necessarily go 'bad' after this point, the quality, flavor, and nutritional values can start to decline. When stored in a freezer, nonfat powdered milk's shelf life can be extended up to 10 years or more. However, when you thaw it, it's best to use it within a week for the best taste and nutritional value.
How do you tell if nonfat powdered milk is bad?
Detecting whether the nonfat powdered milk has gone bad or not is pretty straightforward. First, look for any signs of discoloration. If the usually white powder turns yellowish, it is an indicator of the milk powder being bad. Another sign is musty or stale odor. Finally, if you notice any lumps that don't disappear even after you've vigorously stirred the mixture, it's time to discard the milk powder.
Tips for storing nonfat powdered milk to extend shelf life
• Store the powdered milk in a cool, dry place, away from heat and direct light.
• Use an airtight container for storage once the package is opened. This can prevent moisture and insects from getting in, which can spoil the powdered milk.
• Label the container with the opening date. This helps you keep track of its freshness and when to consume it by.
• If you choose to freeze your nonfat powdered milk, it's best to divide it into weekly portions before freezing, so you don't need to thaw the entire bag every time you need some.
