  • Phalaenopsis (P.) has various species, and some of them have strong fragrance. There are fragrant species such as P. bellina, P. violacea, P. schilleriana and used in breeding program for fragrant Phalaenopsis. This study was performed for establishment of fragrance analysis system using GC-MS and electronic nose in eight P. resources. We analyzed fragrant compound using the tissue of sepal, petal, column, and lip of P. '3010'. The percentage of the major compound was high in the petal and lip tissues. The main compound emitted from P. bellina was linalool (21.21%). It was possible that fragrance pattern could be analyzed among the resources using the electronic nose. Discriminant function analysis (DFA) was more useful than the principal component analysis (PCA) in statistics program. We utilized GC-MS method for the major compounds of flower from our breeding materials. This study would be useful to the fragrant analysis system for the fragrant orchid breeding in the future.

  • Among many kinds of odors, some are known to have effects of sedation or stimulation on brain activity. In this study, brain activity levels affected by four kinds of fragrance0lemon, lavender, jasmine, and rose-were tested using EEG recording. In the first experiment, the quality of alpha wave was examined under controlled rest condition. In the second experiment, the event-related potential (ERP) and contingent negative variation (CNV) were investigated during a simple reaction tasks (SRT) against auditory signal. EEG data obtained for the rest condition were analyzed suing "3-Dimensional Viewer)" which was developed by ourselves to show the chaotic attractor of the signal. Power spectrum were also calculated using FET. EEG data obtained during the SRT were analyzed by comparing CNV amplitudes about each odor condition. Results confirmed the sedative effect of the lemon and the lavender, and the stimulative effect of the jasmine and the rose.

  • It has been common since ancient times to use fashion accessories to make a positive impression on others and develop personal brands. For this manuscript, I've designed a range of personalized electronic sounds and perfume accessories that use personalized scents and sounds to create memorable experiences. These have built-in auditory and olfactory actuators that can generate unique sound and fragrance signatures from the wearer and the other party. Based on the design explorations, I also discussed the issues of design and implementation of personalized electronic sound and fragrance accessories, as well as issues and additional business opportunities for the use of these personalized electronic sound and odor accessories in everyday life.

  • Methyl anthranilate (MA) is a botanical fragrance used in food flavoring with unexplored potential in anti-pigment cosmetics. MA dose-dependently reduced melanin content without affecting cell viability, inhibited dendrite elongation and melanosome transfer in the co-culture system of human melanoma cells (MNT-1) and human keratinocyte cell line (HaCaT), and downregulated melanogenic genes, including tyrosinase, tyrosinase-related protein 1 and 2 (TRP-1, TRP-2). Additionally, MA decreased cyclic adenosine monophosphate (cAMP) production and exhibited a significant anti-pigmentary effect in MelanodermTM. These results suggest that MA is a promising anti-pigmentary agent for replacing or complementing existing anti-pigmentary cosmetics.

  • This paper introduces a system to reproduce the olfactory effect using the MPEG-V (ISO / IEC 23005) standard to verify the reliability of the fragrance used in the olfactory experiment Using the implemented system, with experiment participant wearing HMD(Head Mounted Display), we carried out one-to-one matching of aroma and scent object images, matching images of aroma and many scent objects, matching of aroma and fragrance object images, and analyzing distance preference. The results of the experiment showed that aroma of coffee, cocoa, banana, and peach aroma is suitable scent for testing. In case of coffee aroma with high matching accuracy, 10 ~ 20cm distance between smell and participant was more effective in image matching than 30cm. In the future, we can conduct the olfactory research for enhancing the sense of immersion and presence of virtual reality contents using the selected fragrance.

  • Hydrothermal extraction from dates was done, and then 3 groups of the date extract liquid group (A), the date puree group (B) and the jujube skin flesh group (C) were prepared. And, the omija extract liquid was added to the 3 groups at respective rates of 3:7, 5:5 and 7:3. Then, total 9 medicated diet sources were prepared by adding cinnamon, the ginger extract liquid, honey and pectin. And their physicochenmical and sensory attributes were examined. Total sugar, free sugar and pH increased in the samples of the 3 groups as the addition amount of the jujube extract increased. In chromaticity of respective samples, the "L" value did not show any difference among the 3 groups, but the "a" value was the highest in the "A"group, and "b"value was the highest in the "B"group. In the date puree group and the jujube skin flesh group, their viscosity increased as the addition amount of the jujube extract increased, but in the jujube extract liquid group, no difference was found in its viscosity. As a result of conducting the discrimination test, it was identified that the as the addition amount of the jujube extract was increased, color and sweet taste were feltto be stronger and our taste was felt to be weaker in all 3 groups. In the jujube puree group and the jujube skin flesh group, as the addition amount of the jujube extract increased, the jujube fragrance was felt to be stronger, but in the jujube extract liquid group, no difference was found in its fragrance. And, no difference was found in brightness and viscosity between samples. As a result of conducting the palatability test, no difference was showed in the appearance, but as for the overall palatability including texture, taste and fragrance, preference increased as the addition amount of the jujube extract increased.

  • 'Fleeting fragrance: the history, preservation and display of perfumed clothes' Fragrance - like style - is one of the intangible aspects of costume history that we often wish had been preserved. Garments were perfumed both to impart a pleasurable impression and to mask disagreeable odors from use or from production processes such as tanning and dyeing. Expensive gloves were traditionally perfumed, as well as lace collars, silk stockings and shawls. Both historical and modern attempts have been made to create scents that please the wearer and attract the oppoiste sex, while (preferable) also repelling osquitoes and moths! Unintentional perfuming also occurred, which we sometimes may be lucky to find in our museum collections. How do we describe and identify the transient odors of museum objects, and at what cost can they be preserved and presented for the public? This lecture includes samples of reconstructed historical scents presented in costume exhibitions at the Royal Danish Collections.
