Sarah C. Foster is an undergraduate researcher at William & Mary in Katelynn Perrault Uptmor’s Nontargeted Separations Laboratory. Her research centers around the use of comprehensive two-dimensional gas chromatography (GC×GC) for the analysis of fermented food products. She also applies chemometric methods to GC×GC data to uncover patterns in complex chemical mixtures. Her research interests extend to the influence of microbiology on human nutrition and applying advanced analytical techniques to better understand the impact of products on human health through the analytes they contain.

Volatile Organic Compound Profiling of Commercial Kombucha Using GC-TOF-MS and GC×GC-TOF-MS

By,Sarah C. Foster ,John Chasse

A joint study between William & Mary (Williamsburg, Virginia) and James Madison University (Harrisonburg, Virginia) analyzed volatile organic compounds (VOCs) from commercially produced and locally sourced kombucha products using gas chromatography–time-of-flight mass spectrometry and flame ionization detection (GC-TOF-MS/FID) and comprehensive two-dimensional gas chromatography coupled with TOF-MS and FID (GC×GC-TOF-MS/FID). LCGC International spoke with Sarah Foster, lead author of the paper resulting from this study, about the team’s findings and the key takeaways from this study.
