Volatile Compound Analysis

Volatile organic compound (VOC) analysis identifies compounds in products that could be contributing to off aromas desirable flavors. The Sensory Service Center offers comprehensive flavor analysis, including volatile compound testing coupled to sensory analysis (which ensure our analysis is informed by the flavors specific to your product) to help you track down and eliminate off flavors and prevent further consumer complaints.

For VOC testing, we offer both headspace (SPME) and solvent extraction (DSE SAFE) techniques in conjunction with gas chromatography mass spectrometry (GC-MS) and gas chromatography olfactometry (GC-O). Three GC-MS machines with auto samplers and two GC-FIDs with olfactory sniffer ports are available to ensure high throughput analysis and quick results delivery.¬† We utilize GC-O to refine our GC-MS identification and link Sensory to Instrumental Volatile analysis. This is significant: we perform sensory analysis with our trained panel and that same set of sensory experts run the instrumental analysis. This provides consistency through the experience, bridging a gap and adding a level of accuracy – for example, linking compounds or groups of compounds to specific aromas and off-flavors – that you can’t get when these tests are run independently.
