The results for the drying of parsley cubes at reduced pressures are presented in this paper. The range of the pressures applied was between 6-8 kPa. Parsley without any preliminary preparation, blanched parsley and parsley preliminarily osmotically dehydrated in sodium chloride at concentrations of 10% and 30% were used during the experiment. The course of drying was described with a linear equation for the constant drying rate and exponential functions for the sub-period changes in the drying rate defining the values of the hydration of the material at critical points.
