What is the minimum temperature required for LTLT pasteurization?

The minimum temperature required for LTLT (Low-Temperature, Long-Time) pasteurization is 145°F (63°C). This method involves heating the milk or milk products to this temperature and maintaining it for an adequate period, typically at least 30 minutes. The purpose of this process is to effectively kill pathogenic microorganisms while preserving the quality of the product.

Temperature is critical in pasteurization because it ensures the reduction of harmful bacteria and other pathogens that could compromise safety. While higher temperatures are used in other pasteurization methods, the LTLT method is focused on a lower temperature for a longer time, balancing safety and product integrity.
