项目摘要
I.Fundamental Aspects of odor perception(1)Sensory Test : Based on perceptional change of fragrance of essential oils, a sensory test for perceptional changes of the fragrance of essential oils was developed in relation to type of work, that is, mental work, physical work and hearing environmental (natural) sounds. In evaluating change in perception of a given aroma, perception of fragrance was assessed by 13 contrasting pairs of adjectives and scores were recorded after inhaling a fragrance before and after each type of work. The statistical significance of the change of score for 13 impression descriptors was then examined by Student's t-test for each type of work.(2)Sensory Test for Optically Active Linalools : In order to make clear whether odor perception depend on enantiometric structure or not, attempts were made for enantiomers of linalool, that is (R)-(-)-, (S)-(+)-and (RS)-(±)-forms, in terms of sensory tests. The sensory profiling study using sensory evaluation spectrums rev … More ealed that enantiomers could be regarded to be significantly different odors with dependence not only on species of enantiomer but also on tasks assigned to the subjects.(3)Repeatability Test of the Measurements : Repeatability of the measure was tested in terms of sensory evaluation spectrums. The obtained results suggest that the measure showed a good repeatability and could be useful in assessing changes in the perception of essential oil fragrances.II.Fundamental Aspects of Odor Responses : The effects on humans inhaling the fragrance of essential oils were examined in terms of a multi-channel skin thermometer study and a portable forehead surface electroencephalographic (IBVA-EEG) measurement. The essential oils examined were those of basil and peppermint vs. mental work, linalool and peppermint each vs. mental work and hearing environmental sounds, because our previous sensory test had indicated an opposite sensory spectrum under these circumstances. These imply that the inhalation of linalool or peppermint cause a different odor reaction, depending on the type of work assigned to the subjects (i.e.,mental work or hearing environmental sounds).IlI.Conclusion : Our findings thus indicated some important aspects of the salience of odors, as neurophysiological stimuli, which cause a different perception and lead a diverse odor reaction with dependence on internal and extraneous conditions of the subject.

I.气味感知的基本方面(1)感官测试:基于精油香味的感知变化,开发了与工作类型相关的精油香味的感知变化的感官测试,即脑力工作、体力工作和听到环境(自然)声音。在评估给定香气的感知变化时,通过13对对比的形容词来评估香气的感知,并在每种工作类型之前和之后吸入香气后记录分数。13个印象描述符的得分变化的统计学意义,然后检查学生的t检验每种类型的工作。(2)光学活性芳樟醇的感官测试:为了明确气味感知是否依赖于对映体结构,尝试对芳樟醇的对映体(R)-(-)-、(S)-(+)-和(RS)-(±)-形式进行感官测试。利用感官评价光谱的感官剖析研究 ...更多信息 表明对映体可以被认为是显著不同的气味,不仅依赖于对映体的种类,而且依赖于分配给受试者的任务。(3)测量的重复性测试:根据感官评价光谱测试测量的重复性。所获得的结果表明,该措施表现出良好的可重复性,并可能是有用的,在评估的变化的感知精油fragrances.II。气味反应的基本方面:对人类吸入的芳香精油的影响进行了研究方面的多通道皮肤温度计的研究和便携式前额表面脑电图(IBVA-EEG)测量。研究的精油是罗勒和薄荷与脑力劳动的精油,芳樟醇和薄荷分别与脑力劳动和听到环境声音的精油,因为我们以前的感官测试表明在这些情况下有相反的感觉谱。这意味着吸入芳樟醇或薄荷会引起不同的气味反应,这取决于分配给受试者的工作类型(即,结论:我们的研究结果表明,气味的显着性的一些重要方面,作为神经生理刺激,这会导致不同的感知,并导致不同的气味反应,依赖于受试者的内部和外部条件。少
