  • The adsorption isotherms of dried products of Benincasa hispida at six temperatures (10℃,20℃, 30℃, 40℃, 50℃ and 60℃) over a range of water activities from 0.109 to 0.982 were determined based on the adsorption theory. The experimental data of dried products of Benincasa hispida were fitted by seven models. The optimal model used to describe the adsorption isotherms of dried products of Benincasa hispida was determined by comparing the coefficient of determination (R2), root mean square error (RMSE) and the residual sum of squares (RSS). The net isosteric heat was determined from adsorption isotherms data of dried products of Benincasa hispida at different temperatures. The results showed that the adsorption isotherms of dried products of Benincasa hispida exhibited type Ⅲ sigmoid shape. At the same water activity, as the temperature increased with the decrease of the equilibrium moisture content. The Peleg model was found to be the best for describing the adsorption isotherms of the dried products of Benincasa hispida. The net isosteric heat of adsorption decreased with the increase of equilibrium moisture constant, and approached to zero at high moisture content (about 50%).
