Abstract

The effect of different process variables (osmotic process temperature, concentration and immersion time) and drying air temperature (50, 60 and 70°C) on kinnow peel slices were investigated. Osmotic pre-treatment was carried out using completely randomized design (CRD) for salt (5, 10 and 15%) at various osmotic process temperatures (35, 55 and 75°C) and immersion time (30, 60, 90 and 120 min), keeping solution to peel ratio constant 4:1 (v/w). Osmotic pre-treatment of kinnow peel slices was optimized by Response surface methodology. Optimization was done on the basis of water loss, solute gain and water loss to solute gain ratio. The optimized process parameters for osmotic pre-treatment in salt were 71.4°C osmotic process temperature, 5% concentration and 120 min immersion time.
