A simple method for integrating and extending the binary form of the Gibbs‐Duhem equation for routine application in food technology is given. The integrated equation was used to show that considerable solute‐solute interaction occurs in mixed solutions which, when corrected for in the Ross equation, results in a revised equation whose predictions of the a w of mixed solutions more closely agree with measured values. The revised equation indicates that one can obtain accurate estimates of the a w of a mixed solution by combining estimated water activities with estimated interactions based on the number and concentrations of the solution components.
