Abstract
The influence of the organic trace impurity content on multidimensional spectrums of stimulation – emission – absorption of the samples of ethanol of various origins was investigated. Newly received experimental data allow to es-tablish that ethylic rectified spirits made of different raw materials tend to have a range of luminescent and non-luminescent trace impurities, which can lead to multidimensional spectrum of stimulation – emission – absorption, spe-cific for this sample. On the basis of the experimental data new identification methods for spirits of different origin have been worked out. The methods are designed to develop new quality control system of original ethanol, vodkas and special vodkas, and reveal quickly and accurately the presence of spirits of non-food origin.Keywords
