pasteurization

the process of heating milk to destroy pathogenic microorganisms and delay the development of spoilage organisms. The holding method heats milk to at least 62.8°C (145°F) and holds it at that temperature for not less than 30 minutes. High-temperature short-time (HTST) pasteurization heats to 71.7°C (161°F) for at least 15 seconds. Ultrapasteurization heats to 88.3°C (191°F) for 1 second or 100°C (212°F) for 0.01 seconds.
