Title:
CONTRIBUTION DEGREE EVALUATION METHOD OF ODOR COMPONENT IN COMPOSITE ODOR
Document Type and Number:
Japanese Patent JP2019002840
Kind Code:
A
Abstract:
To provide a method for efficiently evaluating a contribution degree of an odor of an odor component with respect to a composite odor containing a large number of odor components.SOLUTION: In a method, a composite odor is used to a gas chromatography analysis method with an odor smelling port after deciding the quality of an odor which is peculiar to the composite odor, the composite odor is made to possess the quality of the peculiar odor, a peak of the odor component which is high in odor intensity is selected, the composite odor is used to a two-dimensional gas chromatography analysis method with the odor smelling port, the selected peak is separated, a fraction which is composed of a single odor component is dividedly acquired and blended and diluted by a cleaning odorless gas to produce a first simulative odor composition whose similarity with the composite odor is 6 or more, a second simulative odor composition except for at least one of a plurality of odor components constituting the first simulative odor composition is produced, the odor of the first simulative odor composition and that of the second simulative odor composition are compared with each other in terms of similarity, and a contribution degree of the odor component not contained in the second simulative odor composition with respect to the composite odor is evaluated.SELECTED DRAWING: None
