Milk survivals have nothing to do with preservatives
Most people think that milk that can be stored longer can contain a lot of preservatives. But not true. To increase the longevity of the milk, it is as high as 135 degrees Celsius and then cool quickly, so bad bacteria disappear, but all vitamins are preserved. Such a milk can be stored before opening for 120 days and after opening the envelope for up to 4 days.
