The process parameters for osmotic dehydration of aloe vera gel were optimized using response surface methodology. Sugar syrup temperature (30-50 oC), syrup concentration (10-40 oBrix) and duration of osmosis (60-240 min) were the factors investigated with respect to water loss (WL) and sugar gain (SG). The Box- Behnken design of three variables and three levels including 17 experiments formed by 5 central points was used. The solution to sample ratio of 5/1 (w/w) was used. With respect to water loss and solid gain, the linear, quadratic and interaction effects of three variables were analysed. For each response, second order polynomial models were developed using multiple linear regression analysis. Analysis of variance (ANOVA) was performed to check the adequacy and accuracy of the fitted models. The response surfaces and contour maps showing the interaction of process variables were constructed. The optimum operating conditions were found to be syrup temperature of 31.44 oC, syrup concentration of 25.35oBrix and osmosis time of 128.73 min. At this optimum point, water loss and solid gain were predicted to be 39.69 % and 4.45 % respectively.
