Abstract
Abstract A method for deriving a quantitative measure of a beverage which will correlate to the subjective sensory stimuli response of beverage consumers. The method comprises illuminating an aliquot or a dilution thereof with a beam of monochromatic light, measuring the light scattering pattern produced, comparing this pattern to that of a reference pattern, and using the difference between the two patterns as the quantitative measure. A variation of the method is disclosed wherein a number of measurements at a selected set of angles over a period of time are measured and, at each selected angle, the intensity is measured several times. In this method, the average of the intensities so detected at each selected angle is determined, and the numerical set of the fluctuation of each detected value from the average is used to characterize the beverage.
