É apresentado um estudo comparativo entre os métodos oficiais e cromatográficos para a análise de aldeídos e de ácidos em bebidas alcoólicas. Foram analisadas trinta e cinco amostras de destilados alcoólicos. Com respeito a determinação dos teores totais de aldeídos e de ácidos. Os métodos oficiais e cromatográficos apresentam similar exatidão e reprodutibilidade. Entretanto, apenas os métodos cromatográficos permitem identificar e quantificar os componentes de cada série homologa. As metodologias propostas utilizando as técnicas de cromatografia gasosa e cromatografia líquida são simples, rápidas e apresentam maior sensibilidade que os métodos oficiais sendo aplicáveis também a amostras coloridas.A comparative study of official and chromat...
