Popis

General description

Whiskey lactone is the common name of (±)-5-butyl-4-methyldihydro-2(3H)-furanone. It is a volatile aromatic compound found in whiskey and wine aged in oak barrels. The detection of whiskey lactone in blood samples can be done by quantitative gas chromatography–mass spectrometry (dynamic HS–GC–MS) with the limit of detection of about 1,000μgL^-1.

Application

• Investigating the effect of three phenolic fractions on the volatility of floral, fruity, and aged aromas by HS-SPME-GC-MS and NMR in model wine.: This research examines how different phenolic fractions influence the volatility of whiskey lactone among other compounds in model wine, providing insights valuable for winemaking and food chemistry (Wang et al., 2022).


• Accurate Determination of 12 Lactones and 11 Volatile Phenols in Nongrape Wines through Headspace-Solid-Phase Microextraction (HS-SPME) Combined with High-Resolution Gas Chromatography-Orbitrap Mass Spectrometry (GC-Orbitrap-MS).: This paper details a method for accurately quantifying whiskey lactone and other volatile compounds in nongrape wines, enhancing our understanding of flavor profiles in various alcoholic beverages (Liu et al., 2022).
