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. Copyright © 2013 John Wiley & Sons, Ltd.
