A process for osmotic dehydration of plant materials using aqueous solutions of ethanol and sodium chloride is described. Equilibrium data for blanched and unblanched carrots in contact with binary aqueous solutions of ethanol and sodium chloride are presented. Based on the equality of activities of the solutes in carrots and the external solution a successful representation of equilibrium has been obtained in terms of the measurable practical variables such as the total solids in the material at full turgor, solute concentration in the bath and the temperature of contacting.
