This paper presents the resultsof an experimental attempt to improve thedrying kinetics for the retention of colourand sialic acid in edible bird’s nest throughheat pump drying. Kinetics of hot air dryingand heat pump drying were studied byperforming various drying trials on ediblebird’s nest. Isothermal drying trials wereconducted in hot air drying and heat pumpdrying at a temperature range of 40 °C-90 °C and 28.6 °C-40.6 °C, respectively.Intermittent drying trials were carried outin heat pump drying with two differentmodes, which are periodic air flow supplyand step-up air temperature. Experimentalresults showed that heat pump drying withlow temperature dehumidified air not onlyenhanced the drying kinetics but alsoproduced a stable final product of ediblebird’s nest. Heat pump-dried edible bird’ssamples retained a high concentration ofsialic acid when an appropriate dryingmode was selected.
