    The application of a coating on food prior to osmotic dehydration is a promising solution to prevent the large solute intake problem. The influence of different edible coating materials such as Low-Methoxyl Pectinate (LMP), Methyl Cellulose (MC), Potato Starch, and an osmotic sucrose solution with two concentration of 45 and 55% (w/w) on Pears Rings were studied in terms of Moisture Loss (ML), Solid Gain (SG), ML/SG ratio, Effective Diffusivity of solute and water (Des, Dew). Using Fick's first and second laws, the effective diffusion coefficient of water and solute were calculated. Osmosed pears in solution with 55% sucrose concentration showed higher ML/SG ratio as compared with other samples. Pears both coated with 2% MC and osmodehydrated in 55% sucrose, showed not only higher ML/SG ratio but higher diffusivity coefficient as well.
