title: [High pressure extraction of marjoram. 1. Sensory characterization of marjoram oleoresin by profile analysis].
abstract: A flavour profile analysis has been developed for the evaluation of carbon dioxide extracts of marjoram. On the basis of the commercial quality of various proveniences of marjoram a first flavour profile was established. Components which decisively influence the flavour were examined for the determination of relevance factors. The taste profile is the basis for the calculation of the quality coefficient as measure of the sensory quality. The expert profile as a theoretical model is based on optimum intensities of individual taste components. Differences from the expert profile are considered by corrected intensities and lead to a decrease of the quality coefficient. The method used for the development of a high pressure extraction technology is quite suitable for the characterization of marjoram extracts as well as for the evaluation of commercial marjoram samples.
