Development of quantitative analytical method for volatile thiol compound with LC-ESI-MS as nonvolatile derivative by integrating a thiol-specific derivatization

open access: yesBioscience, Biotechnology, and Biochemistry, 2021
ABSTRACT Generally, volatile thiols are hard to be measured with electrospray-ionization-type LC-MS due to the volatility. Therefore, we here evaluated the pretreatment of their S-bimanyl derivatization by monobromobimane to enable the detection as nonvolatile derivative.

Effect of foliar nitrogen and sulphur application on aromatic expression of Vitis vinifera L. cv. Sauvignon blanc

open access: yesOENO One, 2008
Aims: It is well known that vine nitrogen deficiency can negatively impact on aroma in white wines. Soil nitrogen fertilization enhances aroma expression, but it also increases vine vigour and susceptibility to grey rot.

Genetic Determinants of Volatile-Thiol Release bySaccharomyces cerevisiaeduring Wine Fermentation [PDF]

open access: yesApplied and Environmental Microbiology, 2005
ABSTRACTVolatile thiols, particularly 4-mercapto-4-methylpentan-2-one (4MMP), make an important contribution to the aroma of wine. During wine fermentation,Saccharomyces cerevisiaemediates the cleavage of a nonvolatile cysteinylated precursor in grape juice (Cys-4MMP) to release the volatile thiol 4MMP.
