A method is developed to determine time‐temperature equivalencies within discrete particles during thermal processing. Encapsulated calibration materials were examined for establishing the equivalent point for a canning process where results were in good agreement with thermal evaluations using Ecklund thermocouple data. Process characteristics for continuous flow, as Reynolds number, Nusselt number, residence time distribution within heat exchangers and holding tubes, and size and shape of particles are considered for expanding the use of the methodology.
