Equilibrium Moisture Content of Ganoderma Lucidum

Abstract

Equilibrium moisture content (EMC) of Ganoderma Lucidum was determined experimentally at three different experimental temperature (30, 40 and 50°C) and relative humidity ranged from 11.1 to 93.58% using a gravimetric technique. The experimental data of equilibrium moisture content obtained was fitted to four mathematical models (Modified Henderson, Modified Chung ˗ Pfost, Modified Oswin and Modified Haley). A non-linear least square regression analysis was used to evaluate the model constants based on the parameters as: standard error of estimate (SEE), the residual sum of squares (RSS), the quadratic regression coefficient (R2). The result showed that the modified Chung ˗ Pfost model best fitted the experimental data.
