Volatile composition and enantioselective analysis of chiral terpenoids in Tokaj varietal wines

Foods and Contaminants Analysis Using Multidimensional Gas Chromatography: An Update of Recent Studies, Technology, and Applications

“…For alcoholic beverages, in addition to typical wine and whiskey samples, local specialty alcoholic beverages, such as Baijiu (fermented sorghum or other grains), − Huangjiu (Chinese rice wine), , Tokaj wine (Slovakia), , and Syrah wine (Brazil), have been increasingly reported for MDGC applications over the past three years with fewer reports on tea, coffee, and fruit juice. According to Table , a majority of the reported applications aim to profile sample volatiles using GC×GC for general characterization or identify markers and/or evaluate the correlation between chemical compounds and organoleptic attributes of aroma using electronic nose (e-nose), 1DGC–O, and/or MDGC–O.…”

Some applications focus on chiral volatiles using H/C MDGC ,− or GC×GC with a chiral column as the 1 D column (also referred to as e GC×GC). Other reported specific compound groups are sulfur-containing compounds, , sesquiterpenols, lactones, and sesquiterpenes …”

Simultaneous distillation‐solvent extraction gas chromatography‐mass spectrometry analysis of Tokaj Muscat Yellow wines

“…Indeed, these compounds are forming the primary aroma of the wine. Their occurrence in wines can be utilized for the classification of wines into aromatic and non-aromatic ones [14], for specifying grapevine variety [34][35][36], possible adulteration of wine with commercial aromas, or for specifying maceration or fermentation processes [37,38]. Among identified terpenoids linalool, α-terpineol, linalool oxides, and hotrienol were the most abundant.…”

“…VOC profile of Slovak Tokaj varietal wines was characterized by headspace (HS)-SPME-GC-MS. The study showed that relative concentrations of selected VOC enantiomers allowed the classification of Slovak Tokaj varietal wines according to wine variety [14]. However, HS-SPME has disadvantages such as problematic quantitative analysis of samples with higher ethanol content.…”

Investigation of Lactone Chiral Enantiomers and Their Contribution to the Aroma of Longjing Tea by Odor Activity Value and S-Curve

“…Therefore, the enantiomeric ratios (ERs) can be used as an indicator to identify the authenticity of natural products. Recently, researchers have identified many aromatic compounds with chiral isomerism in baked green teas, white teas, spearmint oils, Chios mastic gums, Tokaj variant wines, and Slovak Tokaj wines, such as ( R )-(−)-carvone, ethyl ( S )-(+)-2-methylbutanoate, ( R )-α-terpineol, ( R )-(−)-linalool, ( S )-(−)-limonene, etc.…”
