After determining the optimal treatment, the phenolic\u2010enriched extract was stabilized by spray\u2010drying microencapsulation. Adsorption isotherms of the resulting powders (MCE\u2010SD) were determined at three temperatures and fitted to seven mathematical models to estimate enthalpy and entropy using the Othmer equation.

Isotherms exhibited a type II shape, with the Guggenheim\u2013Anderson\u2013de Boer (GAB) model providing the best fit, followed by the Brunauer\u2013Emmett\u2013Teller (BET), White and Eiring, and Adam and Shove models.
