We are targeting novel smart gas sensor systems to reduce food waste mainly from end consumers. To identify characteristic components and adequate sensors and sensor operation modes suitable for determination of these gas patterns during storage and aging, studies with different foods have been conducted. Besides a GC/MS, the test setup consists of several gas sensors, located both behind the chromatography column and parallel to the GC/MS, i.e. without separation of the compounds. First results show that emissions of aging food can be detected both by the GC/MS and by the gas sensors.
