AI Article Synopsis
- - Aroma relevant γ- and δ-lactones are key flavor compounds in food, and accurately measuring them is crucial for assessing sensory qualities and food authenticity.
- - A high-throughput method using head-space solid-phase microextraction and capillary gas chromatography paired with triple stage quadrupole mass spectrometry was evaluated for analysis.
- - The approach allows for the detection and quantification of γ- and δ-lactones at very low levels (sub-µg/L) in complex wine samples, enhancing reliability in their analysis.
Article Abstract
Rationale: Aroma relevant γ- and δ-lactones are important flavor compounds in various foodstuffs. Their quantitative determination is essential for evaluating food sensory properties as well as food authenticity studies.
Methods: High-throughput head-space solid-phase microextraction as sample preparation, separation by capillary gas chromatography coupled with triple stage quadrupole mass spectrometry has been evaluated as the analytical method.
Results: Monitoring selected reaction mass fragments allowed sub-µg/L quantification of γ- and δ-lactones in complex wine matrices.
Conclusions: Tandem mass spectrometry improves specific detection of γ- and δ-lactones, a prerequisite for reliable quantification at low-µg/L concentration levels in complex wine matrices.
