Pasteurization process parameters

The principle of pasteurized milk is based on the poor heat sensitivity of pathogens and other microorganisms. By controlling the appropriate temperature and time, pathogenic microorganisms in milk can be killed. However, heat-resistant spores cannot be completely eliminated in milk. Therefore, to ensure the quality and safety of the milk products, pasteurized milk must be stored at a low temperature of about 4°C.

The heat treatment methods for pasteurization include: one is Low Temperature Long Time (LTLT), which involves maintaining the temperature at 62~65℃ for 30 minutes; the other is High Temperature Short Time (HTST), which involves holding at 72~76℃ for 15 seconds or 80~85℃ for 10~15 seconds to kill pathogens and reduce the total bacterial count by 90%~95%, while maintaining the sensory qualities and nutritional components of the milk. Additionally, milk contains some components and microorganisms that can affect its taste and shelf life. The purpose of pasteurization is to minimize these microorganisms through heat treatment and to destroy or inhibit enzymes in milk, such as reductase and alkaline phosphatase, thus improving flavor stability and extending shelf life. Many countries and regions widely adopt the combination of 63℃ for 30 minutes and 72℃ for 15 seconds in their relevant regulations and standards.

Intop’s plate pasteurizers and pasteurization tanks can be designed according to your pasteurized milk production line. If you need us to provide equipment that meets your pasteurization process requirements, please contact us.
