EXPLORING INTER-INDIVIDUAL DIFFERENCES IN IN-VIVO FLAVOUR RELEASE BY SIFT-MS

摘要

Selected-Ion Flow-Tube Mass Spectrometry (SIFT-MS) allows on line accurate quantification of several volatile organic compounds down to the ppb range [1]. The technique has been applied to different cases of breath analysis [2]-[5] but to the authors knowledge it has not been applied to monitor in nose flavor release during food consumption for a large population. In this work we describe a SIFT-MS based approach to measure in-vivo nose-space VOCs concentration during consumption of strawberry flavored candies on a large healthy population with the aim to investigate the inter-individual variability in flavor release: nose space analysis might disclose new information regarding the interaction between products and consumers [6].
