Evolution of the concentration of phenolic compounds in cachaça during aging in an oak (Quercus sp.) barrel

Abstract

A cachaça, tradicional e popular bebida brasileira, é obtida por meio da destilação do mosto fermentado de cana de açúcar. Dentre as etapas do processo de produção da bebida, o envelhecimento natural consiste em armazená-la em recipientes de madeira apropriados por um tempo determinado, onde ocorrem alterações na composição química, aroma, sabor e cor da bebida. Este trabalho teve como objetivo realizar um acompanhamento da composição fenólica em diferentes períodos de envelhecimento da cachaça em tonel de carvalho (Quercus sp.). Foram realizadas coletas periódicas durante o período de envelhecimento da cachaça em tonel de carvalho e realizaram-se análise de treze compostos fenólicos utilizando a técnica de cromatografia líquida de alta eficiência com detector de arranjo de diodos (HPLC-DAD). Foi constatado um aumento progressivo na concentração dos compostos analisados ao longo do período analisado, sendo que os compostos encontrados em maior concentração foram siringaldeído e ácido gálico.Cachaça is a traditional and popular Brazilian drink obtained by distilling fermented sugar cane juice. Among the steps involved in its production, natural aging in wood containers for a certain period of time can lead to alterations in the chemical composition, aroma, flavor and color of the beverage. The present work sought to determine the concentration of phenolic compounds after different periods of aging of the cachaça in an oak (Quercus sp.) barrel. Periodic collections during the aging period were performed, and thirteen selected phenolic compounds were determined by high performance liquid chromatography with a diode-array detector (HPLC-DAD). A progressive increase in the concentration of the compounds analyzed was observed, with syringaldehyde and gallic acid as the compounds encountered in the highest concentration.

First Approach to the Analytical Characterization of Barrel-Aged Grape Marc Distillates Using Phenolic Compounds and Colour Parameters

“…Benzoic acid, gallic acid and syringaldehyde were the main low molecular mass compounds in the analysed samples. The results are in agreement with those previously obtained by dos Anjos et al (32) in a study about cachaça. The concentration of minor compounds such as vanillin, syringic and ferulic acids was signifi cantly higher in distillates aged in Quercus robur from Galicia.…”

“…is the estimation of the standard deviation of the regression line, and m is the slope of the calibration curve (32). The LOD and LOQ were low for all determined phenolic compounds (Table 3).…”

“Cachaças” (Sugarcane Spirit) Aged Quantitation of Phenolic Compounds, Antibacterial and Antioxidant Activity

“…Anjos et al (2011) [8], researched "cachaça" samples aged in oak barrels and showed that syringaldehyde and gallic acid were the compounds that showed higher concentration, results that corroborate with those found in this work.…”

“…The methodology used for analysis of phenolic compounds in "cachaça" samples stored in different types of wooden barrels was described by Anjos et al (2011). The standard stock solutions were prepared at a concentration of 1000 mg/L in 40% ethanol at the following concentrations: gallic acid (6.80 mg/L), catechin (11.61 mg/L), vanillic acid (6.73 mg/L), phenol (3.76 mg/L), syringic acid (7.93 mg/L), vanillic acid (6.08 mg/L), syringaldehyde (7.29 mg/L), p-coumaric acid (6.56 mg/L), sinapic acid (8.97 mg/L), coumarin (5.85 mg/L), 4-methylumbelliferone (7.05 mg/L) and o-coumaric acid (6.56 mg/L).…”

Changes in Chemical Composition of Plum Distillate during Maturation in the Presence of Oak Chips under Different Conditions

“…Phenolic compounds were analyzed using a modifi ed method described by dos Anjos et al (27) on an Agilent 1260 Infi nity Binary LC system (Agilent Technologies, Palo Alto, CA, USA), consisting of a binary pump, a vacuum degasser, an autosampler, a thermostated column compartment and a diode array detector (DAD) with a 10-mm max-light fl ow cell. The samples were fi ltered through 0.45 μm PES (polyethersulfone) membrane fi lters (Sigma-Aldrich, Saint Louis, MO, USA) before injection, and separations were performed using an Agilent-Zorbax Eclipse XDB-C18 (4.6 mm×250 mm, 5 μm) column connected to an Agilent-Zorbax Eclipse XDB-C18 4-Pack (4.6 mm× 12.5 mm, 5 μm) pre-column.…”
