A single run liquid chromatography-tandem mass spectrometry method for the analysis of varietal thiols and their precursors in wine.

Journal of Chromatography A, 2021
This research details the development of a novel LC-MS/MS method involving a QuEChERS-based extraction that, for the first time, achieves the fast and concurrent analysis of both free varietal thiols (3-sulfanylhexan-1-ol, 3-sulfanylhexyl acetate, and 4 ...

Revisiting the evaluation strategy of varietal thiol biogenesis.

Food Chemistry, 2018
The varietal thiols 3-mercaptohexan-1-ol (3MH), 3-mercaptohexyl acetate (3MHA), and 4-mercapto-4-methylpentan-2-one (4MMP) are key aroma compounds in wine due to the tropical notes they impart.

Occurrence of Ehrlich-derived and Varietal Polyfunctional Thiols in Belgian White Wines made from Chardonnay and Solaris Grapes.

Journal of Agricultural and Food Chemistry, 2020
Although almost disappeared at the end of the 20th century, Belgian wine production reached a million liters in 2017. The aim of the present work was to identify aroma markers for two white cultivars widespread in Belgium: Chardonnay (the most ...

Ethyl propiolate derivatisation for the analysis of varietal thiols in wine.

Journal of Chromatography A, 2013
Varietal thiols [3-mercaptohexan-1-ol (3MH), 3-mercaptohexyl acetate (3MHA) and 4-mercapto-4-methylpentan-2-one (4MMP)] have been extensively studied in the recent literature. Nonetheless the hardest obstacle for research focussing on this class of compounds is the lack of quick, user-friendly and sensitive analytical methods.

Stability of Varietal Thiols in Commercial Sauvignon blanc Wines

American Journal of Enology and Viticulture, 2011
The intense passion fruit-type aroma of New Zealand Sauvignon blanc wines, attributed to high concentrations of the varietal thiols 3-mercaptohexan-1-ol (3-MH) and 3-mercaptohexan-1-ol acetate (3-MHA), is known to diminish rapidly over just one year in the bottle.

How organic and analytical chemistry contribute to knowledge of the biogenesis of varietal thiols in wine. A review.

Flavour and Fragrance Journal, 2012
ABSTRACTDuring the past 20 years, interest in the involvement of varietal thiols in the aroma of young wines has grown considerably. Most data in the literature dealing with these thiols in wine has focused on 4‐mercapto‐4‐methylpentan‐2‐one, 3‐mercaptohexyl acetate and 3‐mercaptohexan‐1‐ol and demonstrate the central role of the different branches of ...

Influence of Torulaspora delbrueckii in varietal thiol (3-SH and 4-MSP) release in wine sequential fermentations.

International Journal of Food Microbiology, 2017
In last years, non-Saccharomyces yeasts have emerged as innovative tools to improve wine quality, being able to modify the concentration of sensory-impact compounds. Among them, varietal thiols released by yeasts, play a key role in the distinctive aroma of certain white wines. In this context, Torulaspora delbrueckii is in the spotlight because of its

Effects of copper fungicide spraying on volatile thiols of the varietal aroma of Sauvignon blanc, Cabernet Sauvignon and Merlot wines [PDF]

, 2015
In a three-year experiment, the effect of pre-veraison copper sprayings of vines on must composition and some volatile thiols contributing to the varietal aroma of Sauvignon blanc, Cabernet Sauvignon and Merlot wines was studied in comparison with folpet

Construction and Analysis of a Yeast for the Simultaneous Release and Esterification of the Varietal Thiol 3-Sulfanylhexan-1-ol.

Journal of Agricultural and Food Chemistry, 2021
Polyfunctional thiols like 3-sulfanylhexan-1-ol (3SH) and its ester 3-sulfanylhexyl acetate (3SHA) are important aroma determinants in wine with exceptionally low odor thresholds.
