Abstract. Pasteurization means a comparatively low order of heat treatment, generally at a temperature below the boiling point of water. In the recent times, however, thermal treatment applying temperatures far greater than 100 °C only for seconds is also called pasteurization. The method of pasteurization rests upon the principles of thermal ...
