Response Surface Methodology was used for quantitative investigation of water and solid transfer during osmotic dehydration
of kinnow slices in sugar solution. Effects of temperature (45-65?C), Processing time (60?180 minutes), sugar concentration
(50-70?Brix), and solution to sample ratio (1:5 to 1:15) on osmotic dehydration of kinnow slices were estimated. Quadratic
regression equation describing the effect of these factors on the water loss and solid gain were developed. It was found that effect
of temperature and sugar concentration was more significant on the water loss than the effects of processing time and solution
to sample ratio. The osmotic dehydration effect was optimized for water loss, solute gain, and weight reduction. The optimum
conditions were found to be temperature 64˚C, processing time 90 minutes, sugar concentration 54.5?B and solution to sample
ratio 1:10. At these values, water loss, solid gain, and weight reduction were found to be 54.19 (g/100g initial sample), 28.18
(g/100g initial sample), and 26.01 (g/100g initial sample) respectively.
