Abstract

The Latin American flora contains one of the greatest biodiversities in the world. Thus renewable natural resources found in this region acquire an outstanding importance in the search for new useful raw materials for the fragrance and flavor industry. Many chemical and pharmacological studies have been carried on these aromatic resources. However, aromatic quality evaluations are quite scarce. Actually, several analytical technologies are applied to profiling aromatic. These are key issues that influence the development of new agrobusiness ventures. Sensory profiling by different analytical techniques in addition to the chemical characterization can contribute to a better knowledge of these native aromatic plant resources and encourage their potential industrial purposes. Such has been the case of Adesmia boronioides of Patagonia, its essential oils has been used to launch a perfume for a major international cosmetics company in its “Aromas de América” campaign. Actually we have studied other aromatic species of South America, Mulinum spinosum, motivated by previous literature proposing this plant as a surrogate of galbanum, a raw material highly appreciated in perfumery. Chemical analysis was applied by GC-FID-MS and sensory characteristics of the essential oil of this species were evaluated by GC-O and descriptive analysis and compared with that of a commercial sample of galbanum. An experienced panel of reviewers smelled the effluent gas chromatograph using an olfactometer, identifying and describing significant aromas related to chromatographic peaks. The aromagrams obtained from both samples differed significantly, however showed the same descriptors, derivatives of 2-methoxypyrazines were identified as responsible for the characteristic scent note in both products giving the olfactory similarity. Despite this, the overall flavor profile of both products differs substantially, giving Mulinum spinosum own olfactory and promising features.
