Paper describes the studies of parameters for the analysis of papaya glace drying by conducting experiments and finding out appropriate equations to describe these parameters. From the study of drying rate, diffusion equation could explain the drying rate and that the diffusion coefficient increased exponentially with drying temperature. From the study of equilibrium moisture content by using saturated salt solution,it was found that when temperature increased,the equilibrium moisture content decreased if relative humidity was lower than 25 % but increased if relative humidity was higher than 45 %. The equation of Brunauer was found appropriated in describing the experimental results. Finally, density and specific heat increased linearly with moisture content.
