Pro Tips:
1. Did you know that pasteurized milk can stay fresh outside the fridge for about two hours? However, it is recommended to refrigerate it as soon as possible to maintain its quality and prevent potential bacterial growth.
2. In some traditional cultures, such as the Maasai in East Africa, milk is often left out at room temperature for several hours or even overnight before consumption. This is because the milk undergoes a natural fermentation process, creating a tangy and slightly carbonated beverage known as “maasai milk.”
3. The shelf life of unopened UHT (ultra-high temperature) milk, also known as long-life milk, can extend up to six to nine months without refrigeration. UHT milk is first heated to a very high temperature to kill bacteria and then aseptically packaged to maintain its freshness.
4. Milk alternatives, like plant-based milk (e.g., almond milk, oat milk, soy milk), typically have a longer shelf life when unopened compared to cow’s milk. They can usually stay good for several months without the need for refrigeration, thanks to their different preservation methods.
5. In certain regions of the world, especially in areas with colder climates, people used to keep their milk containers submerged in cold running streams or wells. This helped to extend the shelf life of milk for a few extra days, maintaining a cool temperature that slowed down the growth of bacteria.
