A flow cell designed to maintain a stable laminar airflow carrying volatile analytes has been developed.
The detection efforts targeted three non-specific volatile organic compounds (VOCs) linked to bacterial metabolic activity:
-
Dimethyl sulfide (DMS)
-
Methyl thiocyanate (MTC)
-
Dimethyl pyrazine (DMP)
These VOCs can be emitted by multiple sources, including specific plant species, beneficial microbial communities, or biological decomposition.
PickMol™ technology was tested on apples, garlic, and wheat to monitor spoilage—leading to the conclusion that regional foods are the freshest, see for example selected 680 cm-1 band
PickMol™ technology also recognize various kinds of truffles and can control their freshness.
