Abstract
A general purpose tristimulus colorimeter was found to be adequate in determining beet powder pigments (betanin and vulgaxanthin I) concentrations. In comparison with the generally applied spectrophotometric method, the light-reflectance technique was found to be very accurate and reliable for determining the main beet pigments and could be used for rapid determination.
