Pasteurization Time & Temperature Explained
Pasteurization is a process that uses heat to reduce the number of viable microorganisms in a food product, increasing its shelf life and safety. The effectiveness of pasteurization depends on the specific combination of temperature and time used.
High-Temperature Short-Time (HTST) Pasteurization
The most common method for pasteurizing milk is High-Temperature Short-Time (HTST) pasteurization. This method requires milk to be held at a specific temperature for a defined minimum time to ensure pathogen destruction while preserving milk quality.
- Temperature: $72^\circ\text{ C}$
- Time: $15\text{ seconds}$
The combination of $72^\circ\text{ C}$ for $15\text{ seconds}$ effectively eliminates harmful bacteria like Listeria, Salmonella, and E. coli without significantly altering the milk's taste or nutritional value.
Correct Pasteurization Parameters
Based on the HTST standard, the correct time and temperature combination for milk pasteurization is:
$72^\circ\text{ C}$ for $15\text{ seconds}$
