Rahman and Lamb (1990) pointed out that water loss and sugar gain increased linearly with the increase of sugar
concentration and temperature. The rate of sugar diffusion was a function of sugar concentration and temperature.
Concentration of solution is a key factor in the osmotic dehydration process and many research workers have
studied the effect of osmotic solution concentration on mass transfer of osmotic dehydration process. In general,
syrup strength in the range of 60 to 70 0Brix has been found to be optimum (Chaudhary et al, 1993). It was also
reported that higher concentration, faster is the rate of osmosis. Torreggiani (1993) suggested that, it was usually
not worthwhile using higher concentration for osmosis process for more than 50 per cent of weight reduction
because of decrease in osmotic rate with time.
