Pasteurization temperature adjustment for boiling point variations

  1. Nov 27, 2012 #1
    If you are at altitude and let's say water boils at 95 Celsius.

    Pasteurization for an X food product is 30 minutes at 82 Celsius at sea level.

    Now deductively, should I also reduce my pasteurization temperature to 82-5=77 Celsius to compensate?

    No. You should calibrate your thermometer with boiling water and Ice/water slush. A two point linear correction factor should be applied. If you are doing food grade work, you need to use a thermometer that will accurately measure boiling water at 100C and Ice/water slush at 0C. Accuracy costs money.
