Modeling Desorption Isotherms of Four Onion Varieties Related to Temperatures

The sorption isotherm is useful for predicting changes in product stability and the choice of packaging. Therefore, this study aims to establish the desorption isotherm model of the Galmi Violet, Safari, Gandiol F1, and Orient F1 onion varieties related to temperature. The gravimetric method using saturated salt solutions was implemented to determine the desorption isotherms, whose mod- eling, based on empirical mathematical models, was carried out with MATLAB software 6.0.0 using the least...
