The osmotic dehydration causes water removing from food and also a soluble solid uptake into the foodstuffs. However, large penetration of solute into the food becomes a major problem in osmotic dehydration. Pre-coating the food to be dehydrated with an artificial, edible barrier was also explored as a way to efficiently hinder solute penetration. In this study the effect of edible coating (CMC), concentration of sucrose solution (50 and 60%), temperature (35, 45 ºC) of Thomson orange, as a

The results showed that the soluble solid gain(SG) , water loss(WL) and productivity ratio(WL/SG) rise with increase of temperature and solute concentration. Coating has affected significantly on the productivity ratio.
