An integrated approach to assessing the quality of wines sold on Maikop consumer market

Abstract

The quality and safety of food products is one of the main priorities of the Russian State policy in the field of nutrition and well-being of the population.Grape wines are a special type of food product; they are alcoholic beverages obtained as a result of complete or incomplete fermentation of whole or crushed fresh grapes or grape must. The combination of mutual influence of such factors as grape variety, climatic conditions, cultivation methods and production technology gives each wine its uniqueness and character.These features are characteristic for natural drinks, which, unfortunately, are becoming fewer and fewer today, despite the implementation of control and supervisory activities and the adoption of various government regulation measures.The presence of wines of dubious quality on the shelves gives rise to a number of serious consequences, both for public health and for the state economy.The article presents the results of research on a comprehensive assessment of the quality of wines sold on the regional consumer market.The determination of the organoleptic and physico-chemical parameters of wines regulated by GOST has been carried out according to the methods established in the current regulatory documents; the determination of the qualitative and quantitative composition of volatile components and cationic composition has been carried out using the gas chromatographic method and the capillary electrophoresis method.It has been established that 30% of the total volume of wine samples studied is distinguished by rather low organoleptic characteristics, with full compliance with the established requirements in terms of physical and chemical indicators, and 10%, based on the total assessment of organoleptic, physical and chemical indicators, component and cationic composition, are identified as counterfeit products.
