Expiration & Storage Tips
When does nonfat plain yogurt expire?
Nonfat plain yogurt usually has a use-by or expiration date printed on the packaging, which typically falls between 2 to 3 weeks from the purchase date. This is an approximate date indicating when the product is likely to remain at its best quality. Once the yogurt has been opened, it should ideally be consumed within 5 to 10 days. Freezing nonfat plain yogurt is possible and can extend its shelf life up to 1 to 2 months, though this may slightly alter its texture upon defrosting.
How do you tell if nonfat plain yogurt is bad?
To check if nonfat plain yogurt has gone bad, first look at its appearance. If you notice any color changes, mold growth, or a hard texture on the surface, the yogurt is likely spoiled. Additionally, if the container appears bloated, it's a clear sign of bacterial activity and the product shouldn’t be consumed. A rotten or sour smell, stronger than the typical tangy aroma of yogurt, is also an indication that it has spoiled.
Tips for storing nonfat plain yogurt to extend shelf life
• Always store your nonfat plain yogurt in the refrigerator at a temperature below 40°F (4°C), ideally in the back where it’s cooler, and away from strong-smelling foods to prevent it from absorbing their odors.
• After opening, ensure that the yogurt’s container is tightly sealed when not in use to prevent any possible contamination.
• If you want to freeze yogurt for later use, consider portioning it into small quantities before freezing. This way, you only defrost the amount you need each time.
• Thaw frozen yogurt in the refrigerator rather than at room temperature to maintain its quality and safety.
