Distinção entre cachaças destiladas em alambiques e em colunas usando quimiometria

Abstract: Recebido em 20/2/08; aceito em 6/10/08; publicado na web em 5/2/09 DISTINCTION BETWEEN CaChaçaS DISTIllED IN POT STIllS aND IN COlUmNS USING ChEmOmETRICS. One hundred fifteen cachaça samples derived from distillation in copper stills (73) or in stainless steels (42) were analyzed for thirty five itens by chromatography and inductively coupled plasma optical emission spectrometry. The analytical data were treated through Factor analysis (Fa), Partial least Square Discriminant analysis (PlS-Da) and Quadratic Dis… Show more

“…[1][2][3] The expansion of the consumer market has encouraged improvements, implementation of stricter controls, and more detailed studies regarding the production process, as well as improving the chemical quality of the beverage. 4 Among the steps involved in beverage production, natural aging involves storage in suitable wooden containers for a certain period. In Brazil, this step is not required.…”

“…Essa técnica também tem sido aplicada para avaliar parâmetros sensoriais durante o processo de envelhecimento da cachaça (CARDELLO; FARIA, 1998) e também para traçar o perfil sensorial por meio dos teores de compostos fenólicos totais, pH, teores de cobre, cor e acidez fixa, volátil, em amostras de cachaças comerciais envelhecidas e sem envelhecer (CARDELLO;FARIA, 2000). Diversos trabalhos utilizam a técnica para a diferenciação de bebidas destiladas em alambiques e em colunas, e a caracterização da bebida por meios dos voláteis nelas presentes (RECHE; FRANCO, 2009;SERAFIM et al, 2011).…”

“…do material afeta diretamente a qualidade final do produto. [15][16][17] Aparelhos construídos exclusivamente em aço inox conduzem a produtos com características sensoriais desagradáveis, relacionadas aos teores de dimetil sulfeto (H 3 CSCH 3 ), liberado no processo e que permanece no produto final. [14][15][16] O emprego de dispositivos construídos com cobre, no aparelho destilador, diminui a ocorrência de compostos com propriedades organolépticas negativas.…”
