Summary Ross' equation for estimating the water activity of multicomponent solutions was tested with experimental data in solid intermediate moisture foods. Literature experimental data on water activity and food system composition in a wide variety of intermediate moisture foods (IMF) were utilized to test the validity of Ross' equation. The results obtained were satisfactory and indicate that Ross' equation constitutes a simple and reasonably accurate method for predicting the water activity in IMF.
