Prediction of lycopene degradation during dehydration of watermelon pomace (cv Sugar Baby)
Lycopene retention in watermelon pomace during drying was investigated in fluidized-bed and cabinet dryer at 50–70 °C using 2–6 kg/m2 tray loads. Page’s model described the drying behaviour of watermelon pomace better than other models. Lycopene content of watermelon pomace dried in fluidized-bed dr...

| description | Lycopene retention in watermelon pomace during drying was investigated in fluidized-bed and cabinet dryer at 50–70 °C using 2–6 kg/m2 tray loads. Page’s model described the drying behaviour of watermelon pomace better than other models. Lycopene content of watermelon pomace dried in fluidized-bed dryer was 5.67–9.86 mg/100 g (db) whereas in cabinet dryer 4.82–8.12 mg/100 g (db) under experimental conditions. Lycopene retention was lower in cabinet dryer due to longer drying time. Degradation kinetics of lycopene in watermelon pomace followed first order model over 50–90 °C. Thermal degradation showed higher lycopene retention than drying under similar conditions of temperature and time indicating that circulating air increased the rate of lycopene degradation. Lycopene loss during drying of watermelon pomace was 19.02–60.57% whereas 7.46–43.28% was observed during thermal treatment of watermelon pomace. Fluidized bed dryer can be employed preferably over cabinet dryer to stabilize the watermelon pomace with higher lycopene retention. |
