<P>PROBLEM TO BE SOLVED: To provide a method for sterilizing beverages without causing deformation/breakage of containers even during rise and drop of the temperature in a pressure chamber where the containers each charged with a beverage generating gas when heated are disposed. <P>SOLUTION: The method for sterilizing beverages comprises the following process: disposing containers each sealed in such a condition that each of the containers is charged with the beverage generating gas from the inside of the container when heated up to a temperature necessary to be sterilized, in the pressure chamber 20; raising the pressure in the pressure chamber so that pressure difference (M2-M1) between pressure M2 in the container and pressure M1 in the pressure chamber lies within a prescribed range; raising the temperature of the chamber L1 up to a prescribed temperature to raise the temperature in the container L2 so as to keep the container in the pressure chamber in the prescribed temperature for prescribed period of time in order to sterilize the beverage in the container; decreasing the pressure in the pressure chamber so that the pressure difference between the pressure in the container and the pressure in the pressure chamber stays within a prescribed range; and decreasing the temperature in the pressure chamber to make the temperature in the container fall down. The device for sterilizing beverages is used for performing the method. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
