Characterization of Volatile Compounds in Celery Scent

Headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-time-of-flight mass spectrometry (GC-TOFMS) offers a powerful approach for identifying the complex volatile profile of produce. By utilizing mathematical deconvolution and retention index tools, this method successfully resolves coeluting analytes to provide high-confidence characterization of the hundreds of compounds that contribute to the unique aroma of celery.
