WebJul 20, 2024 · A novel method (dynamic water transfer–based water activity analyzer (DWT) method) based on Fick’s law of diffusion for the accurate measurement of moisture sorption isotherm (MSI) has been developed and was compared with saturated salt solutions (SSS) method and dynamic vapor sorption (DVS) method. MSIs at 25 °C of sultana raisins … The main application of DVS is to measure water sorption isotherms. In general, a vapor sorption isotherm shows the equilibrium amount of vapor sorbed as a function of steady state relative vapor pressure at a constant temperature. For water sorption isotherms, water relative vapor pressure is more commonly expressed as relative humidity. In a DVS experiment this is accomplished by exposing a sample to a series of step changes in relative humidity and monitoring the mass chan…
