Mexican Plum (Spondias purpurea L.) Moisture Sorption Properties

摘要

Type Ⅱ isotherms were obtained using the gravimetric static method with discontinuous registration of weight changes for Mexican plum powders. The monolayer moisture content, obtained using the BET or GAB model, was in the range 6.18-4.17 g H_2O/100 g d.s. The average standard error, obtained using the GAB or Oswin fitting, was in the range 7.87-33.76. However, the Oswin model better fit the moisture sorption experimental data of Mexican plum powders.
