When is it safe to eat a stale frozen yogurt? The easiest way to tell if the yogurt has gone bad is by its smell. While a small amount won’t harm you, a smell that resembles that of rotten milk means the yogurt has gone bad. A more noticeable odor indicates the yogurt has lost its original flavor and is no longer edible. To maximize its shelf life, keep it properly frozen and thawed.
If you have a regular refrigerator, you can leave your frozen yogurt out for up to two hours before you realize it’s gone bad. If you leave it out for longer than this, it could start to develop fungus or mold. This is not a good sign and you should discard it. If you are not able to recognize the signs of stale yogurt, you should throw it out and buy a fresh one.
A bulging yogurt container is an indication that it is spoiled. This is caused by air expansion in the tub. When the tub is less full, the more air expands and spoils the yogurt. Other tell-tale signs of spoilage are mold spots, a yeasty flavor, or effervescence. If you notice any of these signs, stop eating the yogurt immediately.
The top foil cover on yogurt containers is a great way to keep it fresh. You can also store it in the fridge and thaw it. Frozen yogurt can be kept for up to two months in the freezer. Once it is thawed, it will have a different texture or appearance. You can then consume it or use it for other purposes.
