Sažetak
The drying characteristics of sweet potato (Ipomea batatas L.) were investigated using a laboratory convective tray drier at different drying temperatures and pre-treatments. The drying temperatures were 50, 60, 70, 80 °C, and airflow velocity 2.8 ms-1. Different physical and chemical pre-treatments of sweet potato samples were applied as follows: hot water and steam blanching ; dipping in: 0.5% ascorbic acid solution, 0.15% 4-hexylresorcinol (HR) solution, 0.3% L-cysteine (LC) solution. Pre- treatment with 0.15% 4-HR resulted in the most reduced drying time and high rehydration ratio, while pre-treatment with 0.3% LC solution resulted in the minimum colour change.
