Abstract
According to Simpson and co-workers the Revisited General Method (RGM) has the capability to generate the isolethal processes from a single heat penetration test. As described in Simpson and co-workers when the isolethal processes have been generated, then utilizing the cubic spline interpolation procedure, it is possible to attain a continuous function. Natural cubic splines are used for creating a model that can fill in the holes between data, in effect, approximating a trend. They are, therefore, useful for making observations and inferences about a pattern existing in the data. A piecewise technique which is very popular. Recall that the philosophy in splining is to use low-order polynomials to interpolate from grid point to grid point. This is ideally suited when one has control of the grid locations and the values of the data being interpolated (i.e., you have a way to produce them at any location as in thermal processing). The purpose of this proposed methodology is to explore and analyze the potential application of the RGM method to generate isolethal processes at different TRT and F 0 values and implement simultaneous sterilization of different product lots in the same retort.
