1864 - Pasteurization is invented (Louis Pasteur, France)
Perfect Pasteurization Means Perfect Protection

Pasturization is simply heating milk - not boiling it.

By raising the temperature of the milk to 145 degrees Fahrenheit and keeping it at that point for thirty minutes, all harmful germs are destroyed, by the milk is not changed.


After heating, the milk, is immediately cooled to 40 degrees or less and flows to the bottling machine and is automatically filled and capped; thus avoiding contact with human hands.
