Mathematical models that describe kinetic of the osmotic dehydratation of the fruit tissue are used for projecting new drying processes or optimization of the already existing ones. Essential understanding process has great practical and economical importance. Due to the exceptional complexity of mathematical description of essential physic and chemical phenomenona that appear during osmotic dehydratation, still there is no universal model for osmotic dehydratation of fruit tissue. Basic problem that disables description of a mathematical model of real process consistes mainly of the fact that basic laws describe separate, individual phenomena, until the drying process is a result of interaction of multiconditional phenomena. The equations which are aiming to comprehend such interaction are only on athempt to converge to the real process which is happening inside of the material. The paper argues about three approaches of mathematical modeling of kinetic fruit tissue drying that can be recognized in literature: theoretical, semi theoretical and empirical.
