Odor Measurement

Odor measurement in Japan

The triangle odor bag method, the most popular olfactory sensory test in Japan, was first developed in 1972, and introduced into the Offensive Odor Control Law in 1995. This is an air dilution method in which “odor index” is measured. In recent years, the necessity of developing quality control system for olfactometry and standardization of measurement procedure for the promotion of nationwide ...

Overview of Odor Measurement Techniques

“Odor” is elicited by chemicals in a gas phase which are detected via olfaction producing recognizable smells (cinnamon, lemon) and/or chemesthesis which mediates pungent sensations (tingling, burning, etc) in response to substances such as ammonia. Responses transmitted by the olfactory nerve elicit aroma. Many compounds are pungent at high concentrations. Many compounds detected by chemesthes...

Measurement of Odor Threshold by Triangle Odor Bag Method

The detection thresholds of odor substances analyzed in field investigations were measured by the triangle odor bag method. The number of substances used for the experiment is 223. The experiment was carried out from 1976 to 1988. As the results of the experiments, the odor thresholds were distributed over the concentration of large range depending on the odor substances. Isoamyl mercaptane exh...
