More Information
Summary:The invention provides a method and apparatus for efficiently measuring and analyzing volatile and relatively non-volatile flavor components released during oral processing of food or other products. The subject exhales a breath sample into one or more temperature-controlled collection chambers (12), preferably at predetermined time intervals during the oral processing of the product. Each breath sample is then purged from its collection chamber (12) with a non-reactive gas flow into an adsorbent, absorbent or other trap (30) containing an interface that separates and collects the volatile and relatively non-volatile components from the breath sample. The trap (30) is then transferred to a thermal desorber (36) to release the volatile and relatively non-volatile flavor components from the interface surface into a measuring and analysis apparatus (32,34).
