Abstract:	An improved design for on-line analysis of in-mouth (in-vivo) aroma release while eating food and drinking beverages was developed at the Nestlé Research Center. It addresses two shortcomings of former set-ups. On the one hand, it permits sampling breath-air under conditions close to a natural eating situation. The ergonomic design of the nosepiece allows panellists to breathe freely and comfortably and to have some freedom of movement while performing the experiment. On the other hand, the novel sampling set-up achieves high sensitivity and time resolution of the analysed breath-air volatiles. Here we discuss technical aspects of the solution and demonstrate on two examples its performance. This includes release of aroma compound from liquid model systems, and in-mouth aroma release from a freshly prepared espresso coffee.
