Yoghurt, a beloved dairy product enjoyed by millions around the world, is known for its creamy texture and tangy taste. But have you ever wondered whether yoghurt needs to be refrigerated? The answer may surprise you!
Yoghurt is made by fermenting milk with live bacteria cultures, which convert lactose, a natural sugar found in milk, into lactic acid. This process not only gives yoghurt its distinct flavor, but also helps to preserve it. The acidity created by the fermentation process acts as a natural preservative, inhibiting the growth of harmful bacteria.
While yoghurt can be safely stored at room temperature for a short period of time, it is highly recommended to refrigerate it to maintain its freshness and to extend its shelf life. Refrigeration slows down the growth of bacteria and helps to prevent spoilage.
So, to answer the question, yes, yoghurt should be refrigerated to ensure its quality and safety. However, keep in mind that once you open a container of yoghurt, it should be consumed within a reasonable time frame, as exposure to air can contribute to the growth of bacteria.
