Volatile characterization
Characterization
refers to volatile profiling plus measurement of aroma activity.
We employ all the tools associated with volatile profiling, plus
we conduct gas chromatography olfactometry (GCO). This information
may be utilized to find an off-flavor in a product. It also is useful
to determine key aroma impact compounds for QA. We utilize a time
intensity method along with voice recognition.
Our experience with GCO dates back to 1993
when Russell Bazemore worked with Mina McDaniel at Oregon State
University as a grad student. Mina developed the Osme time intensity
technique.
