| Summary: | The Cassia alata leaf is widely used for the medical uses as it is beneficial for treatment of skin diseases such as purities, eczema and allergy. The moisture sorption behavior included desorption and adsorption of C. alata leaves were investigated using standard static gravimetric method. The sorption isotherm was obtained at ambient temperature 24 °C and with the equilibrium relative humidity (ERH) range from 11.3 to 84.3 %. The equilibrium moisture content (EMC) of C. alata increased from 8.67 to 28.50 g water/dry matter with increasing ERH during desorption. It is similar to adsorption which the EMC increased from 21.28 to 32.85 g water/dry matter. The color quality of C. alata leaves were lower with increasing the ERH. |
