How do you pasteurize milk?
In the United States, the most common method of pasteurization is High Temperature Short Time (HTST). This method involves using metal plates and hot water to raise the temperature of the milk to at least 161 °F (71 °C) for no less than 15 seconds, or 145 °F (62 °C) for 30 minutes, followed by rapid cooling.

What are 3 methods of pasteurization?
Different Types of Thermal Processing Methods Thermization: Heat the milk to between 57°C to 68°C and hold for 15 minutes. Batch pasteurization: Also known as low-temperature long time (LTLT) pasteurization. Flash pasteurization: Also known as high-temperature short time (HTST) pasteurization.
What is difference between pasteurization and sterilization?
Different methods are used in order to kill harmful microorganisms. The sterilization is a process that destroys all microorganisms and their spores, while the pasteurization destroys only the vegetative forms of the bacteria and the spores survive.
What are the disadvantages of pasteurization?
