- Abstract
4-Methoxy-2-methyl-2-butanethiol is a powerful sulfur-containing aroma compound identified several decades ago in blackcurrant buds ( Ribes nigrum L.). However, an unambiguous identification in blackcurrant fruits has been lacking. In this study the occurrence of 4-methoxy-2-methyl-2-butanethiol in blackcurrant berries has been demonstrated for the first time by the analysis of seven cultivars. After isolation of the volatiles by vacuum-headspace-extraction, the sulfur-containing compound was enriched on mercurated agarose gel. Identification was performed via capillary gas chromatography/mass spectrometry. Quantitation was performed in the single ion monitoring mode using 4-methyl-4-sulfanylpentan-2-one as internal standard. The concentration of 4-methoxy-2-methyl-2-butanethiol in Andega (4.5 µg/kg) was significantly higher than those in the other cultivars investigated in this study (from 0.16 to 0.72 µg/kg). Calculation of the odour activity values indicated that this sulfur-containing volatile contributes to the aroma of blackcurrant berries. Copyright © 2016 John Wiley & Sons, Ltd.
