The new methodology includes the identification of the 1H and 13C NMR chemical shifts of the analytes by a standard addition method and the consequent identification of the compounds studied in regular and non-alcoholic beers. The chemical composition is different depending on whether the beer is regular or non-alcoholic, therefore affecting the organoleptic characteristics of each type of beer.
