The purpose of this study was to evaluate the kinetics of freezing in cylindrical slices of different thicknesses of cashew apple fruit. The models used were those proposed by Plank and Pham and compared with experimental data obtained by slow freezing of the slices. The thermophysical properties were estimated using numerical models of Choi and Okos. According to the experimental values of cylindrical slices of 1 and 2 cm, the mean freezing times were 72 and 87 min, respectively. The values estimated by the mathematical models for freezing time, had higher relative mean deviation for the Plank model. Thus the model proposed by Pham was more suitable for predicting the freezing time for cashew apple fruit slices.
