This study was conducted to determine the effect of osmotic dehydration on air drying characteristics of pomegranate arils. Osmotic dehydration was performed at different time and temperatures combinations. Mass transfer parameters were studied using response surface methodology. After osmotic dehydration, the arils were air dried till moisture content became 8.0%. Page model of drying was fitted on experimental data. Osmotic pretreatment decreased the exponential coefficient of the model. Osmotic dehydration conditions and air drying constant were combined in a single mathematical model with optimization at lowest time for overall dehydration. This goal was achieved when the arils were pretreated for 93 minutes at 39°C. This research might help to choose drying conditions for pomegranate arils on an industrial scale.

Abstract Combined osmotic dehydration (sucrose solution: 50–70 % w/w, 30–50 °C for 2 h followed by air drying at 40 and 60 °C) is an appropriate process for preservation of oil retention capacity, lightness and yellowness of lemon peels (Citrus limon. v. lunari). Incorporation of sugars to lemon cuboids pieces increased drying rate during the first falling rate phase of the air dehydration step and improved their color stability. Osmotic dehydration process allows protective effect against further total phenol loss during air drying: significant loss of total phenol content (70–80 %) was recorded during osmotic dehydration and then it remains constant during air drying at 40 and 60 °C. For the investigated temperature of osmotic pre-treatment (30–50 °C), water retention capacities were reduced by up to 70 % and were maintained constant during air drying.

In this work the authors have studied the effect of hot-air drying with or without a previous osmotic dehydration pretreatment to produce dried cut persimmon with a different geometry (slices and sectors). A kinetic study has been carried out analysing mass variation, colour and texture changes in samples. Two sensory analyses were also performed considering drying time and geometry. Furthermore, the influence of 35 days of storage on optical and mechanical properties was also determined. The results obtained showed that geometry did not affect the parameters analyzed. According to the results of the kinetic study, the selected drying times were 8 and 12 hours. Osmotic pretreatment does not imply improvements in the final product. Judges preferred slices dried for 8 hours without osmotic pretreatment. The time of storage did not influence the optical and mechanical properties.
