Drying Kinetics and Drying Models of Terong Dayak (<em>Solanum lasiocarpum</em>)

Abstract

Drying using a hot air chamber was tested on samples of terong dayak (<em>Solanum lasiocarpum</em>). Drying kinetics curves of drying <em>S. Lasiocarpum</em> demonstrated that drying at 55°C and relative humidity of 10% were the optimum values for drying <em>S. Lasiocarpum</em>, with the appropriate equations using the Page’s model drying equation $MR = exp (-0.5494t^{1.4052})$ that produced 96.8% accuracy. According to the results which showed the highest average values of $R^2$ and the lowest average values of MBE and RMSE, therefore it can be stated that the Page model could describe the drying characteristics of S. lasiocarpum in the drying process at a temperature of 55°C and relative humidity of 10%.
