Methods of Pasteurization
Pasteurization is a process which consists of heating milk to a certain temperature for a definite time to ensure destruction of harmful bacteria.
There are three methods of Pasteurization
• Holding method or Batch process : In this method milk is held at 62.8 degrees centigrade for 30 minutes and then rapidly cooled to prevent multiplication of surviving bacteria.
• High temperature short time ( HTST ) method or continuous process : Milk is heated to 71.7 degree centigrade for not less than 15 seconds.
• Ultra High temperature method : Milk is heated to a temperature of 93.4 degrees centigrade for 3 seconds
