Abstract
This paper describes a study of usefulness of some optical methods to determine the grape variety and the age of Bulgarian wines from Southern Bulgaria. We have tested two optical methods measuring the optical density and fluorescence spectra in the UV region. The data for color intensity, hue and color composition have been obtained by using absorbance spectra. A correlation between fluorescence intensity and antioxidant activity of the wine can be found, which is very important for human health and hygiene of eating. All of the obtained experimental results suggest that two optical methods could be useful for quality estimation of wine age and quality determination of some fluorescence components in wine with antioxidant properties.
