Abstract: An odor adsorbent material, an odor detection kit, and a method for using the same for rapidly identifying a facility where binding of an odor component had occurred among facilities used in a distribution route of a commodity. The odor detection kit includes at least two pieces of an odor adsorbent material, a package section that includes at least two storage sections and is configured to store the odor adsorbent material, and a sheet section. The odor detection kit is installed in a facility. At least one of the pieces of the odor adsorbent material is exposed to open space in the facility, recovered therefrom, and sealed and stored. At the time of testing, occurrence of odor emission in the facility is determined by comparing odor components adsorbed by each of the pieces of the odor adsorbent material.
