Description A mathematical model was developed for moisture tran,~fer ill nudtiple package systems wherein different food products or components are packed in individual primal 3' packages and fitrther unitized in a seconda O" package. Tile Guggenhein~-Anderson-de Boer (GAB)equation for moisture sorption isotherm was differentiated with respect to time and incorporated in the generalized moisture transport equation for the multiple package system resulting ill a system ~[simultaneous ~6rst order differential equations relating changes in water
activities of the products to storage tittle. These equations are solved hv the Runge-Ktttta method, and the corresponding moisture changes in tile products are obtained by using the original isotherm equations. The computer programme developed on tile basis of the
model was used to simulate moisture changes in a 2-component multiple package system ~)[doughnut mix. The predictions were in close
agreement with tile eaperimental values.
