The experimental kinetic data concerning the linear growth rate of L-sorbose crystals in water solutions with addition of methanol or ethanol (batch crystallization process) are presented. The growth rate values were estimated on the basis of the product-crystal size distributions analysis. For the calculation purposes the kinetic models of continuous mass crystallization process in a MSMPR apparatus were adapted: size independent growth (SIG) model and Rojkowski exponential size dependent growth (SDG) model. It is observed that the 15 mass % of MeOH (or EtOH) addition into the solution destined for batch cooling crystallization (55 mass % of L-sorbose) causes the crystal growth rate decreasing - according to a SDG model - from G = 8.81ź10^-8 m s^-1 (water) to G = 2.15ź10^-8 m s^-1 (MeOH) or G = 2.84ź10^-8 m s^-1 (EtOH).
