MEANS OF IDENTIFICATION OF COUNTERFEIT VODKA BY ADMITANTS REACTIVE COMPONENT

Abstract

Methods of control of parameters of alcohol solutions, in particular methods of identification of falsified vodka by change of reactive component in the frequency range of the test sinusoidal signal are analyzed. Emphasis is placed on two types of falsification. The first type concerns falsification by replacing vodka with an aqueous-alcoholic solution. The second - the replacement of vodka from one brand to another. Based on the analysis of the results of experimental studies, two ways to identify such falsification have been proposed.
For the first type of product falsification, the inspection is performed by measuring the reactive component of the controlled object's admission at two fixed frequencies; for the second, the substituted brand of vodka is determined by measuring the frequency at which the reactive component of the admixture takes an extreme value. For both methods of identification, the structures of the means by which these methods can be practically implemented are proposed and presented in the figures. The means of identification used the admixture converter of the controlled object to a complex voltage, the informative parameter of which is its reactive component.
To implement the identification of counterfeit vodka by substituting the brand, the block diagram of the tool contains a generator of a given frequency range. In this range, the frequency at which the reactive component is of extreme value is recorded. The obtained frequency determines one or another brand of vodka. The block diagram of the means for implementing the method of falsification of vodka with water-alcohol solution contains a generator of two frequencies. Reactive components are measured at these frequencies, processed, and then the identification result is recorded.

The figures show the proposed methods for detecting counterfeit products, as well as schemes of measuring instruments for conducting experiments with these methods.
Conclusions on the work performed are presented: methods of detecting falsifications of vodka products are analyzed; proposed schemes of tools for practical use in inspections, which consist of simple common electrical components, although they give accurate measurement results in the detection of counterfeit products.
