Abstract: The drying characteristics of bitter melon slices under different conditions of different temperature (or power), slice thickness and slice wet weight were studied by hot air drying and microwave drying. The drying curve was drawn.
The results show that the optimum conditions for hot air drying are drying temperature of 60 °C, slice thickness of 0.5 cm, slice wet weight of 20 g, and dehydration rate of 95.9 %. The optimal process conditions for microwave drying equipment are drying power of 800 W. The slice thickness was 0.5 cm, the wet weight of the slice was 20 g, and the dehydration rate was 96.4%. This study can provide a theoretical reference for the improvement of bitter melon slice drying process.
