MODELING OF WATER ACTIVITY AND ENTHALPY OF WATER SORPTION IN CASSAVA CHIPS

Abstract
The Guggenheim-Anderson-de Boer (G.A.B.) and modified Henderson equations adjusted by linear and non-linear regression were used for mathematical description of sorption isotherms of yuca. The highest result of generalized correlation coefficient was obtained by the G.A.B. direct nonlinear regression. Weighted linear regression of results for isosteric heat sorption must be employed to fit the Clausius-Clapeyron equation.
