The mass transfer parameters and changes in the water and
soluble solids (DMwt and DMsst, respectively) were calculated using
Equations (1) and (2); Mot and Moo represent the sample weight at
times t and 0, respectively, and Xwt, Xsst, Xwo and Xsso are the water
(w) and soluble solid (ss) mass fractions in a sample at times t and 0,
respectively.
