Equilibrium moisture content equations for some medicinal and aromatic plants

In this research, the most commonly used equilibrium moisture content (EMC) and equilibrium relative humidity (ERH) equations are compared on their ab ility to best fit the published sorption data for selected medicinal and ar omatic plants. A non-linear regression technique is used to fit data subset s. In order to compare the performance of the EMC/ERH equations, three stat istical error parameters are used. The best-fitted equations which provide a sound basis for future work on drying and storage of medicinal and aromat ic plants are given. (C) 1999 Silsoe Research Institute.
