In food processing, pasteurization (also pasteurisation) is a process of food preservation in which packaged foods (e.g., milk and fruit juices) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life.
The following year, pasteurization was demonstrated at the Columbian Exposition in Chicago. Commercial milk pasteurization was introduced in Baltimore in 1893, but Cincinnati is credited with the first large-scale pasteurization program in America. New York City followed in 1898, although pasteurization was not required for some years. [3]
