✦ Synopsis

In this research, seven equilibrium moisture content (EMC) and equilibrium relative humidity (ERH) equations (modi"ed Henderson, Chung}Pfost, Modi"ed Halsey, Henderson, Chen}Clayton, Iglesias}Chirife and modi-"ed Oswin) are compared on their ability to "t data for some medicinal and aromatic plants. Thirteen data sets comprising 13 plants are used. Comparisons are based on standard error of estimate, coe$cient of determination, residual sum of square and residual plots. Both the modi"ed Halsey and the modi"ed Oswin equations were found as the most versatile models to accurately describe the equilibrium moisture content and equilibrium relative humidity (EMC/ERH) relationships for medicinal and aromatic plants. The modi"ed Henderson equation is a good model for fennel and cinnamon. The Chung}Pfost equation is suitable for muscat, coriander, ginger and cinnamon. The Iglesias}Chirife, Henderson and Chen}Clayton equations are among the least successful models for medicinal and aromatic plants, respectively.
