Longlife milk. Cartons containing longlife' milk. Left to right they are: skimmed, semi-skimmed and full milk. Longlife milk, also known as UHT (ultra-high temperature) milk, is heated above 135 Celsius for one or two seconds. This kills spoilage organisms and gives the milk an unrefrigerated shelf life of six to nine months. Once opened, it is treated as normal milk.
