Pasteurization or Pasteurisation is a process in which packaged and nonpackaged foods (milk) are treated with mild heat, usually to less than 100 °C to eliminate pathogens and extend shelf life.
HTST Pasteurization Temperature is regulated at close limits and overheating is prevented.
Raw milk feed temperature : 4-35 deg C
Pasteurization temperature: 80 deg C
Holding time for pasteurization : 300 seconds
Finished milk temperature: 10 deg C
Heat regeneration efficiency: 90%
Improves preservation quality by destroying almost all spoilage organisms
Pasteurization by heating and time treatments are a compromise among bacterial killing along with a number of other factors such as taste, phosphate inactivation, cream line reduction, etc.
