Tag: Yogurt storage

According to food scientists, the watery liquid found at the top of a yogurt container, including Greek yogurt, is a natural and completely normal occurrence called 'whey separation'. This translucent, protein-rich substance is a byproduct of the fermentation process and does not indicate spoilage.

Studies show glass containers can be superior for keeping yogurt fresh for longer periods than plastic. Understanding what you should store yogurt in is key to maintaining its quality, taste, and safety, whether it's store-bought or homemade.

According to the USDA's FoodKeeper app, refrigerated yogurt should be consumed within one to two weeks of purchase. This general guideline provides a starting point, but the specific shelf life of yogurt tubes can vary based on whether they are opened or unopened and how they are stored. Proper refrigeration and keen observation are key to ensuring safety and quality.

According to U.S. Dairy, yogurt can only sit out at room temperature for up to two hours before it must be refrigerated. Eating yogurt that was left out for too long significantly increases your risk of getting sick from foodborne bacteria. The 'danger zone' for bacterial growth is between 41°F and 140°F.

According to scientific research, freezing yogurt does not kill all the good bacteria, but rather causes them to enter a dormant state. This process is different from heat, which actively destroys live cultures, so the myth that freezing yogurt destroys the good bacteria is largely inaccurate.
