| Outline of Final Research Achievements |
It is popular to use fresh herbs and spices as “Yakumi” for Japanese cuisine, because their fresh flavor improves pleasant aroma or inhibit unsatisfied flavor of other foods. In this study, we focused on the flavor generation of ginger and Japanese pepper, and performed comprehensive analysis and clarified contributing factors for generation of their flavor. (1) Comparative analysis of immature and mature ginger rhizomes screened some key compounds which differentiate flavor profiles of them. Furthermore, yellow pigment of ginger rhizomes was dependent on the contents of curcumin, demethoxycurumin and 6-dehydrogingerdione. (2)We isolated and confirmed geraniol dehydrogenase (ZoGeDH) responsible for generation of geranial, a characteristic aroma compound in ginger. (3)Multivariate analyses of volatile profiles from eight kinds of Zanthoxylum leaves showed that Z. piperitum (Japanese pepper) lines were differentiated by high content of citronellal.
