1864
It was Louis Pasteur who invented the process of pasteurization.
PASTEURISATION
Pasteurisation does not kill all bacteria in the milk. Some bacteria are not killed in the heating process and will start to multiply again after pasteurisation. Cooling after pasteurisation is needed in order to limit the amount of bacterial growth that occurs. Bacteria reproduce very slowly in cold conditions, but very quickly in hot conditions. Cooling is the only preservative that is used after pasteurisation.
