Abstract

Pomegranate juice processing produces a large amount of peel as a by-product or waste which is a potential source of raw material for food and other bioprocessing industries, such as(fights acne, pimples and rashes, helps in detoxification of body, cures sore throats and coughs, arrests hair loss and prevents dandruff, improves dental hygiene). Drying the peel offers opportunities for value addition into novel products, thus reducing amount of produced waste from the fruit processing operations. The dry parameter was drying air temperature (65, 75 and 85°C) and drying air velocity (1, 2 and 3 m/s) at layer thickness of 7mm. The results indicated that the initial moisture content of 244% (d.b) decreased to a range between 6 and 4% (d.b) at the end of drying process depending on the drying conditions. The results obtained show that moisture content of the by-product decreases with time and temperature. Two thin-layer drying models were selected to describe experimental drying kinetics data. The models were compared based on their coefficients of determination (R2), reduced chi square (χ2) and root mean square error (RMSE) between Observed and predicted moisture ratios. On the other hands, the calculated operation cost of the dryer approaches about 5.5 E/kg, while the price of 1 kg of dried pomegranate peel is 35 LE in the market.
