UHT pasteurization is a really important thing in making food and drinks. The word UHT means Ultra-High Temperature. So foods, specially liquids like milk or juice, get heated to very high temp for short time only. This kills bad germs and bacteria. Because of that, the product can last way longer without fridge.

UHT work by heating the liquid over 135°C (around 275°F) just for few seconds. This high heat destroy bacteria and other tiny things that make spoilage or make people sick. After that, they cool it fast and put in clean sterile pack. This stop new bacteria coming in. One good thing about UHT is it keep the taste good and nutrition stay almost same. For example milk with this can taste close like fresh one. Vitamins and minerals don't get lost much, which is good for health eating.
