How Long Does Powdered Milk Last?
How long does powdered milk last? It can last for years beyond its "best by" date. Once the powder is reactivated with water, it should be used within 4-5 days. This is because powdered milk is real milk that has been heated so that about half of the milk solids evaporate. A package of powdered milk will list the ingredients of nonfat dry milk and vitamins A and D3, other products with lists of ingredients are not the real deal. As usual, if you take out the moisture you drastically increase the shelf life of the product allowing you to always have some milk on hand. The shelf life of powdered milk is mainly influenced by its exposure to heat and moisture.

Of course, all food and drink lasts for a shorter period of time if they are not stored properly. But remember that powdered milk, unlike a lot of other dairy products, usually has a "best by date" which is the last date by which a manufacturer will vouch for a product's quality, not its safety. Because of this distinction, you may safely use it to compliment your favorite meals even after its best by date has lapsed.
