| The study on osmotic pretreatment of oyster mushrooms was carried out in order to remove the moisture prior to further mechanical drying. Three salt concentration level (10, 15 and 20 g/100 g), two temperature levels of osmotic solution (30 and 45°C) and constant solution to mushroom ratio of 10 (w/v) were selected and the observations on water loss and solid gain were taken at an interval of 30 min up to 300 min. The osmotically pretreated samples were further dried up to its equilibrium moisture content in a tray drier at 60°C and experimental data were fitted successfully using Page and Henderson & Pabis model. The osmo-convective dehydrated samples were evaluated for its quality parameters i.e. color (L, a, b, ∆E, C* and h°), rehydration ratio... |

| Abstract Watermelon rind, comprising 35% of the fruit’s total mass, usually discarded due to its unappealing flavor and lack of sweetness. In this study, candied watermelon rind was prepared through osmotic dehydration at vacuum (VOD) and atmospheric pressure (OD). The effects of independent variables (sucrose concentration, immersion time and temperature) on the dependent variables, including solid gain (SG) and water loss (WL) of watermelon rind, were evaluated using multiple response surface methodology. The SG and WL increased with the increasing sucrose concentration, immersion time and temperature for both VOD and OD, but VOD greatly increased the mass transfer rate. The kinetic constants were obtained by fitting the data of SG and WL to the Fick’s... |
