  • Title: Prediction of sweetness intensity for equiratio aspartame/sucrose mixtures.
    Author: Schifferstein HN.
    Journal: Chem Senses; 1995 Apr; 20(2):211-9. PubMed ID: 7583014.
    Abstract:
    The Equiratio Mixture Model predicts the responses to a series of equiratio mixtures on the basis of the psychophysical functions for the unmixed components. The model predicts the sweetness of mixtures of sugars and sugar-alcohols successfully, but is unable to predict mixture intensity for substances with different dynamic ranges. In this paper, the equi-intensity concept is introduced in the Equiratio Mixture Model by transforming the physical concentrations expressed in molarity into units that produce approximately equi-intense sensations. An empirical test using aspartame/sucrose mixtures shows that the modified Equiratio Mixture Model yields good predictions of mixture intensities.
