Measurement of the water sorption properties of a Ritz Cracker sample

All the reported measurements were performed using the standard Hiden Isochema IGAsorp instrument (see technical data sheet 143) with a refrigerated water bath to thermostat the sample chamber. The IGAsorp is a fully automated system, which allows the accurate and efficient determination of moisture sorption equilibrium isotherms and kinetics in foodstuffs. The purpose of this experiment was to demonstration the application of the IGAsorp in the area of food research. The equilibrium isotherm with GAB analysis is presented together with the results of kinetic analysis showing the variation of equilibration time with humidity.
