Using automated sorptive extraction to detect trace-level odour-active compounds in plant-based foods
Aroma Chemistry Group, Research Institutes of Sweden (RISE)
RISE’s Aroma Chemistry Group shows how automated high-capacity sorptive extraction on Centri with HiSorb makes it easier to detect trace odour-active compounds in plant-based proteins.
Switching between headspace and immersive sampling, using splitless desorption and trap enrichment to boost sensitivity, the team cuts sample size from ~500 g to 10–20 g and streamlines a previously day-long purge-and-trap process.
The result is faster method development and better correlation between sensory panels, GC–olfactometry and GC–MS, helping developers reduce beany off-notes in new products.

- Customer: Aroma Chemistry Group, Research Institutes of Sweden (RISE)
- Application: Aroma profiling of legume-derived protein-rich powders
- Challenge: Reducing the sample size needed to detect trace-level off-odours
- Solution: HiSorb™ high-capacity sorptive extraction, automated on the Centri® sample preparation and preconcentration platform
- Results: More efficient, unattended monitoring of ppt–ppb atmospheric VOCs, leading to significant research publications
The headspace and immersive sampling options on Centri help us reveal a broader spectrum of volatile compounds
