As the precepted flavor of food is strongly determined by the compounds entering the nose during mastication and swallowing, nosespace analysis is of particular importance for food and flavor scientists. Thus, PTR-MS coupled to a nosespacesampler has become an indispensable tool for food industry and research over the decades.
Several years ago, we attempted a nosespace study during the consumption of different instant soups utilizing a (back then) stateof- the-art PTR-MS instrument with about 5000 m/Δm mass resolution. To our surprise, we could not find reasonable correlations between flavor-relevant compounds in the soup and detected concentrations in the nosespace.
In 2024 we repeated the study, but this time using the current benchmark for PTRMS instruments, the FUSION PTR-TOF 10k with its mass resolution of about 15,000 m/Δm and sensitivities of up to 80,000 cps/ppbv.
