Computerized Model for the Prediction of Thermal Responses of Packaged Solid‐Liquid Food Mixture Undergoing Thermal Processes

摘要

ABSTRACTA COMPUTERIZED MODEL for the prediction of thermal responses and lethality of packaged particles‐liquid food was developed by assuming a statistical particle volume distribution for spherical, cylindrical, oblate spheroidal‐shaped particles. For the model development, an overall heat balance equation was solved in combination with an equation for transient heat conduction. To solve the latter, Duhamel's theorem and empirical formulae containing f‐ and j‐values were used. The reliability of the model was verified experimentally by processing canned potatoes‐in‐brine in an agit
