Sorption and desorption isotherms of celery roots

Abstract

An experimental study for determining the wet basis equilibrium moisture content in celery root (Apium graveolens) was conducted. Empirical equations describing the isotherms of sorption and desorption of the product at a temperature of 20°C were obtained. The values for the wet basis equilibrium moisture content for higher temperatures – 40, 60 and 80°C were theoretically calculated. All results were summarized in analytical, graphical and tabular form.
