Direct Analysis of Volatile Compounds in Real Time Using DART-MS (Part 1) Analysis of Flavor Release from Chocolate-like Food

Attempts have been made to continuously measure the volatile compounds that pass through the nose during mastication. However, these involve humans as the testing medium and present various problems, such as the difficulty in repeating tests multiple times and the long data collection intervals. The DART (direct analysis in real time) system, which is able to directly ionize samples, could be used to rapidly analyze such volatile compounds if the compounds could be introduced into the ion source efficiently.
This Application News describes an example of continuously measuring the volatile compounds emitted as a chocolate-like model food melts.
