Expiration & Storage Tips
When does skim milk expire?
Unopened skim milk can last for up to a week past the printed date on the package, given proper storage conditions. Once opened, it should be consumed within five to seven days for the best quality and safety. You can also freeze skim milk, which will extend its shelf life for up to three months. Just remember to leave some room for it to expand when it freezes!
How do you tell if skim milk is bad?
If skim milk is going bad, the first thing you'll probably notice is a sour smell. It might start to develop small clumps or a yellowish color. When you pour it, the milk may look grainy or have a watery consistency. If any of these signs are present, it's best to toss it out. Always remember, when in doubt, throw it out!
Tips for storing skim milk to extend shelf life
• Always keep skim milk stored in the refrigerator, between 34 and 38°F
• Once opened, close the lid tightly and return it to the refrigerator immediately after every use
• Avoid storing skim milk on the door of the fridge as the temperature is more variable, instead, keep it on the middle or lower shelf
• To freeze skim milk, pour it into an airtight container leaving 1 to 1 1/2 inches of headspace for expansion and pop it in the freezer
• When defrosting, place it in the refrigerator until fully thawed and shake well before using to evenly distribute the fat particles in the milk
