Yogurt storage:

Lactic acid bacteria like relatively low temperature, and the temperature range suitable for survival is relatively narrow. Generally speaking, the range of 2 degrees Celsius to 10 degrees Celsius is more suitable for the survival of active bacteria. But in most cases, the room temperature will exceed this temperature range, even one or two times higher. Our comfortable room temperature may have been completely burned to death for lactic acid bacteria.

Therefore, when you buy yogurt, you should buy yogurt in the refrigerator, and be careful not to freeze it. And after buying it, put it in the refrigerator and freezer at home in the shortest possible time, and keep the temperature at 4 or 5 degrees Celsius, which is more suitable for the survival conditions of lactic acid bacteria.
