The concentration of OD was an important tool to reduce the water content with little bit damage
on the quality of fresh products. This was done with the mild treatment of product at low temperature (30-
50°C) so that temperature did not affect the properties of cell membranes, which was necessary to maintain the osmotic phenomenon (Lazarids, 2001). The plant tissue was continuously immersed in the osmotic medium because oxygen was not exposed so that there was no need of use of antioxidant to protect against enzymatic and oxidative discoloration (Dixon et al., 1976)
