Comparison of immersive room and virtual reality, through the consumption episode "Eating a sandwich in a park"
2020
International audience; Conventional approaches for consumers’ tests, CLT and HUT, lead respectively to a high either internal or external validity. In recent years, several immersive approaches have been developed to achieve both internal and external validity at the same time, i.e. environments close to actual consumption context while keeping parameters under control. Virtual reality (VR) is one of the most promising one.In this study, we assess two immersive strategies in terms of internal and external validity for a consumption episode “having a sandwich for lunch in a park”. The two experimental conditions were an immersive room (N = 57, Fig. 1) and a VR environment (N = 55, Fig. 2). …

In vivo aroma release by APCI-MS and PTR-MS: impact of water content of exhaled air and evidence for competition between aroma compounds
2013
Livre ISBN-13 : 978-3-902811-91-2; International audience; Atmospheric pressure chemical ionization mass spectrometry (APCI-MS) or proton transfer reaction mass spectrometry (PTR-MS) has been in use frequently for in vivo aroma release studies. In APCI-MS, protonated water clusters formed from moisture in the expired air are used as reagent ions. Yet the influence of a change in relative water content in the ionization gas on the data collected have been rarely studied and conflicting results were obtained. In this context our first objective was to study the impact of water content of the expired air on the level of aroma release measured by APCI-MS and to compare with the results obtained…
