Mass transfer of pork meat cubes (M. triceps brachii), shaped as 1x1x1 cm(3), during osmotic dehydration (OD) and under atmospheric pressure was investigated in this study. The effects of different parameters, such as concentration of sugar beet molasses (60-80 mass%), temperature (20-50 degrees C), and immersion time (1-5 h) in terms of water loss (WL), solid gain (SG), final dry matter content (DM), and water activity (alpha(w)), were investigated using experimental results. Five artificial neural network (ANN) models were developed for the prediction of WL, SG, DM, and alpha(w) in OD of pork meat cubes. These models were able to predict process outputs with coefficient of determination, r(2), of 0.990 for SG, 0.985 for WL, 0.986 for alpha(w), and 0.992 for DM compared to experimental measurements. The wide range of processing variables considered for the formulation of these models, and their easy implementation in a spreadsheet calculus make them very useful and practical for process design and control.
