The effects of osmotic dehydration on mass transfer properties and microbiological profile were investigated in order to determine the usefulness of this technique as pre-treatment for further treatment of meat. The process was studied in two solutions (sugar beet mo- lasses, and aqueous solution of sodium chloride and sucrose), at two temperatures (4 and 22 °C) at atmospheric pressure. The most significant parameters of mass transfer were determined after 300 min of the dehydration. The water activity (aw) values of the pro- cessed meat were determined, as well as the change of the microbiological profile between the fresh and dehydrated meat. At the temperature of 22 °C the sugar beet molasses proved to be the most suitable as an osmotic solution, despite the greater viscosity. Keywords:
