- 摘要：
To provide a method for producing a packed chilled food product and by which a high sterilizing effect is obtained without performing a high temperature thermal treatment exceeding 100° C, whereby the deterioration of the flavor and texture of the food product can be prevented to give the chilled food product having a long open date.
SOLUTION: A packed chilled food product is subjected to two or more steps of high pressure treatments changing the pressure at least once in a pressure range of 100 to 700 MPa in a state heated at a temperature little affecting the flavor of the food product at about 40 to 80° C for a total time of 4 to 30 min and thereby highly efficiently germinating spore bearing bacteria growing at low temperature of not more than 10° C, and then subjecting to a low temperature sterilizing treatment at 60 to 100° C for sterilizing the germinated spore bearing bacteria. Thus, since the germinated spore bearing bacteria can be sterilized by the high pressure treatment and the very high sterilizing effect is obtained without performing a high temperature thermal treatment exceeding 100° C, and the spore bearing bacteria growing at low temperature of not more than 10° C can especially efficiently be sterilized.
