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. ## Claims ### Claim 1 A method for recovering an odor detection kit, the method including: removing an odor detection kit installed in a facility for production or distribution of a commodity, the odor detection kit including a first odor adsorbent material and a second odor adsorbent material; a package section that includes a first storage section capable of storing the first odor adsorbent material and a second storage section capable of storing the second odor adsorbent material; and a sheet section, wherein the first odor adsorbent material is sealed in the first storage section, the second odor adsorbent material is exposed to an external open space located in the facility, the open space being an odor detection target, and the first storage section and the second odor adsorbent material are installed in the open space; storing and sealing, in the second storage section, the second odor adsorbent material exposed to the open space in the facility; entering, in the sheet section, information that specifies at least a time when the odor detection kit has been recovered; and after the sealing and the entering, sealing the odor detection kit in a pouch material that has barrier property and odorless property. ### Claim 2 (depends on 1) The method for recovering the odor detection kit according to claim 1, wherein the method is conducted when transporting a commodity out of the facility. ### Claim 3 (depends on 1) The method for recovering the odor detection kit according to claim 1, the method further including entering, in the sheet section, information that specifies the facility. ### Claim 4 (depends on 3) A method for testing the odor detection kit recovered by the method for recovering the odor detection kit according to claim 3, the method including: specifying, based on an identification number given to a commodity, a facility used in production and distribution processes of the commodity and a time of usage; and selecting the odor detection kit that is to be a subject for testing, based on the specified facility and time of usage, and information that specifies a time of usage and a facility entered in the sheet section of the odor detection kit. ### Claim 5 An odor testing method including: installing, in an exposed state, at least one piece of an odor adsorbent material having been packaged in a condition that prevented adsorption of odor outside of a packaging of the odor adsorbent material, in a facility for production or distribution of a commodity, such that a first piece of the odor adsorbent material is installed in the facility in an exposed state of being exposed to open space in the facility; recovering the first piece of the odor adsorbent material installed in the facility; testing at least odor components adsorbed by the recovered first piece of the odor adsorbent material; comparing a test result obtained from the testing with a comparison result, which is a result of testing odor components adsorbed by a second piece of the odor adsorbent material in a blank state, the blank state being a state other than the exposed state of being exposed to the open space, to thereby determine a difference between the test result and the comparison result; and determining whether an odor has been emitted in the facility based on the determined difference between the test result and the comparison result. ### Claim 6 (depends on 5) The odor testing method according to claim 5, further including: testing an odor component adsorbed by the second piece of the odor adsorbent material at a time point when the odor adsorbent material had been installed, wherein the comparison result includes a result of the testing of an odor component adsorbed by the second piece of the odor adsorbent material at the time point when the odor adsorbent material had been installed. ### Claim 7 (depends on 5) The odor testing method according to claim 5, wherein at least an organoleptic test is performed at one of or both of: the testing of an odor component adsorbed by the recovered first piece of the odor adsorbent material; and the testing of an odor component adsorbed by the odor adsorbent material at a time point when the odor adsorbent material had been installed. ### Claim 8 (depends on 5) The odor testing method according to claim 5, wherein the installing of the odor adsorbent material in the exposed state is conducted when transporting the commodity in the facility. ### Claim 9 (depends on 5) The odor testing method according to claim 5, wherein the recovering of the odor adsorbent material is conducted when transporting the commodity out of the facility. ### Claim 10 (depends on 5) The odor testing method according to claim 5, wherein the odor adsorbent material has a sheet shape. ### Claim 11 (depends on 10) The odor testing method according to claim 10, wherein the odor adsorbent material is formed by laminating polyethylene on both sides of an elastomer film. ### Claim 12 (depends on 10) The odor testing method according to claim 10, wherein the odor adsorbent material has an area size not smaller than 100 cm2. ### Claim 13 (depends on 10) The odor testing method according to claim 10, wherein, at the installing of the odor adsorbent material in the exposed state, the installing is conducted by having at least one surface of the odor adsorbent material uncovered. ### Claim 14 (depends on 5) The odor testing method according to claim 5, wherein the odor adsorbent material adsorbs substances having a bad odor or a sweet smell, including mold odor components including haloanisoles, insect repellents such as naphthalene, agricultural chemicals or fragrances. ### Claim 15 (depends on 5) The odor testing method according to claim 5, wherein the blank state is a state of remaining sealed and stored inside the packaging.
