Analytical quality control of wines and wine materials

Abstract

Ensuring food safety of the quality of sold products is one of the urgent problems of the wine industry. The trend of falsification of well-known brands of domestic and imported wines is a characteristic feature of the modern market of wine products. Known methodological bases for assessing the quality of wine products in most cases do not have the potential to recognize many modern «technological solutions». To solve this problem an analytical method can be proposed on modern equipment "FTIR BACCHUS 3". This analyzer allows you to determine the chemical substances and the range characteristics of these substances. This method has been chosen for the identification of wine samples and not by chance, when using it, the analysis time is significantly reduced, and the range of chemical elements determined by the analyzer is quite wide, and reagents are not needed for this equipment. The method does not require preliminary preparation of samples; it is also quite new, not popular in Russia. The article presents a comparative review of classical wine identification methods. The presented material indicates the relevance of creating a database on the chemical composition of wines that determine their authenticity using new instrumental techniques. The proposed multi-parameter wine analyzer FTIR BACCHUS 3 is a system for the analysis of worts and wines using chemometric methods, based on the acquisition of the mid-IR spectrum (FTIR). The method is based on chemometrics, i.e. obtaining chemical data using mathematical methods of data processing and extraction, which will increase the reliability of assessing the authenticity and place of origin of wine products.
