Pasteurized
Pasteurization is a milk heating process to sterilize potentially disease-causing bacteria and prolong milk's shelf life.
Most milk is heated to at least 72 CELSIUS for just a few seconds, which is well known as HTST(High-temperature Short-Time).
Milk pasteurized at smaller dairies or in homes usually undergoes a low-temp pasteurization (heated to 145° F for at least 30 minutes) to create a minimally processed product intended for quick consumption. There’s also something known as Ultra-Heat Treatment (UHT), or "ultra-pasteurization," whereby milk is heated to 280° F for a just a couple seconds. This technique is what's used to create that "shelf-stable" milk you'll find unrefrigerated, as it creates a shelf-life of 6 to 9 months if the aseptic cardboard containers its sold in are left unopened — but many milks, not just the shelf-stable ones, are ultra-pasteurized.
