Abstract:

This article discusses the theoretical foundations, practical applications and analytical
capabilities of the photoelectric colorimetric method in determining the chemical composition of
alcoholic products. The study explains the relationship between optical density and concentration in the
process of determining the amount of ethanol, fusel oils, aldehydes and other impurities based on the
Beer–Lambert law developed by August Beer and Johann Heinrich Lambert. The results obtained using
a photoelectric colorimetric method are of great importance in quality control of alcoholic beverages,
sanitary requirements and optimization of production processes
