high-temperature-short-time method
Quick Summary
Pasteurization is a heat-treatment process designed to eliminate harmful microorganisms in foods and beverages, named after scientist Louis Pasteur. The high-temperature short-time (HTST) method, also known as flash pasteurization, is a common technique.
In HTST pasteurization, milk is typically heated to about 72 Ā°C (162 Ā°F) for 15 seconds, followed by rapid cooling. This process effectively destroys pathogenic bacteria like Mycobacterium tuberculosis and other harmful microorganisms, while also reducing spoilage microbes to extend shelf life. This method is efficient for large-scale commercial operations.123
Ultrahigh-temperature (UHT) pasteurization involves even higher temperatures, heating milk to 138ā150 Ā°C (280ā302 Ā°F) for just one to two seconds. This allows the product to be stored without refrigeration for several months. While effective for preservation, UHT products may have a different flavor profile compared to conventionally pasteurized items.43
