Quality study of light beer of the domestic production

Abstract

The aim of the study. Conducting research to assess the quality of light beer of various brands of domestic production. During the research, methods for determining the organoleptic and physico-chemical indicators of beer quality, set out in current regulations, methods of analysis and comparison, statistical methods of processing research results and expert assessments were used. As a result of research of quality of seven samples of light beer of domestic production which is present in the market, it is established that by results of the analysis of marking of the investigated samples of beer only three – samples № 1, 2 and 4 meet the established regulatory requirements. Other samples have deficiencies in labeling, in particular, no maximum tolerances and no mass percentage of dry matter in the initial wort as a percentage. It was found that organoleptic quality indicators, such as: appearance, aroma and taste only in sample № 6 meet the requirements of regulatory documents, in other samples there are slight deviations from the norm. Experimental commodity research on physicochemical parameters: mass fraction of alcohol, acidity and color, showed non-compliance with the established requirements only in sample № 5 in terms of acidity. All other samples had values that did not exceed the norms established in the domestic standard. The obtained research results can be useful for retailers and wholesalers. The conducted commodity research allows manufacturers to improve the quality of products on indicators that deviate from the normalized values and improve labeling in accordance with the requirements of regulations.
