How osmosis principle of moving water, some food items from the diet by soaking in a solution at a concentration
greater than or precious water activity (water activity: aw) under the food. The difference between the pressure osmotic of the
solution to food cause propulsion (driving force) which cause mass transfer between the solution osmotic and
by the diffusion of water from the food pieces through the membrane. to the solution And at the same time the spread of solids from
solution through the membrane to the piece. Furthermore, the potential spread of natural substances such as vitamins, organic acids released from
the cells with small amounts (Lerici et al, 1985) have introduced sugar and salt to prepare a solution osmotic an
extensive grill. Because there are many advantages such as the ability to melt high price was a good performance to pull water
out of a piece of food and help improve the taste of food after osmosis equipment (Sachetti and Board, 2001) to understand. to
conduct mass transfer of osmosis, which this research, experiments with cantaloupe and to serve as a preliminary to the development.
