Detection data on the volatile component is acquired by using a detector. When the food product is spoiled, at least one of a type of the food product or a degree of spoilage of the food product is determined based on the detection data. ## Claims ### Claim 1 A food product spoilage determination method comprising: trapping a volatile component released from a food product; acquiring, by using a detector, detection data on a plurality of components included in the volatile component; and when the food product is spoiled, determining, based on the detection data, at least one of a type of the food product or a degree of spoilage of the food product. ### Claim 2 (depends on 1) The food product spoilage determination method of claim 1, wherein the detection data includes information according to an amount of the plurality of components included in the volatile component. ### Claim 3 (depends on 1) The food product spoilage determination method of claim 1, wherein the food product includes pork, and the plurality of components included in the volatile component include at least one selected from the group consisting of 1-decanol, 2-butanone, ethyl 2-methylbutyrate, 2-pentanone, dimethyl disulfide, dimethyl trisulfide, ethyl tiglate, isobutyl alcohol, trimethylamine, 2-heptanone, and isobutyl isobutyrate. ### Claim 4 (depends on 3) The food product spoilage determination method of claim 3, wherein the plurality of components included in the volatile component include at least one of the 2-heptanone or the isobutyl isobutyrate. ### Claim 5 (depends on 1) The food product spoilage determination method of claim 1, wherein the food product includes chicken, and the plurality of components included in the volatile component include at least one selected from the group consisting of 1-decanol, 2-butanone, ethyl 2-methylbutyrate, 2-pentanone, dimethyl disulfide, dimethyl trisulfide, ethyl tiglate, isobutyl alcohol, trimethylamine, anisole, and styrene. ### Claim 6 (depends on 5) The food product spoilage determination method of claim 5, wherein the plurality of components included in the volatile component include at least one of the anisole or the styrene. ### Claim 7 (depends on 1) The food product spoilage determination method of claim 1, wherein the food product includes pork and chicken, and the plurality of components included in the volatile component include at least one selected from the group consisting of 1-decanol, 2-butanone, ethyl 2-methylbutyrate, 2-pentanone, dimethyl disulfide, dimethyl trisulfide, ethyl tiglate, isobutyl alcohol, trimethylamine, 2-heptanone, isobutyl isobutyrate, anisole, and styrene. ### Claim 8 (depends on 7) The food product spoilage determination method of claim 7, wherein the plurality of components included in the volatile component include at least one of the 2-heptanone or the isobutyl isobutyrate and at least one of the anisole or the styrene. ### Claim 9 (depends on 1) The food product spoilage determination method of claim 1, wherein the detector includes a gas sensor. ### Claim 10 (depends on 9) The food product spoilage determination method according to claim 9, wherein the gas sensor is a sensor array including a plurality of sensor elements having sensitivity characteristics different from each other. ### Claim 11 (depends on 1) The food product spoilage determination method of claim 1, wherein the detector is a gas chromatograph. ### Claim 12 (depends on 1) The food product spoilage determination method of claim 1, wherein the determining is performed based on the detection data by using a learned model obtained by executing machine learning using training data. ### Claim 13 A spoilage determination system comprising: a detector configured to detect a volatile component released from a food product to output an output signal; and a processor, the processor including an acquirer configured to acquire the output signal and generate, from the output signal, detection data on a plurality of components included in the volatile component and a determining unit configured to, when the food product is spoiled, make, based on the detection data, a determination as to at least one of a type of the food product or a degree of spoilage of the food product. ### Claim 14 (depends on 13) The spoilage determination system of claim 13, wherein the determining unit is configured to make, based on the detection data, the determination by using a learned model obtained by executing machine learning using training data. ### Claim 15 (depends on 14) The spoilage determination system of claim 14, wherein the determination includes a discriminant analysis based on the training data and the detection data. ### Claim 16 (depends on 13) The spoilage determination system of claim 13, wherein the detector includes a gas sensor. ### Claim 17 (depends on 16) The spoilage determination system of claim 16, wherein the gas sensor is a sensor array including a plurality of sensor elements having sensitivity characteristics different from each other. ### Claim 18 (depends on 13) The spoilage determination system of claim 13, further comprising a display unit configured to display a result of the determination. ### Claim 19 (depends on 13) The spoilage determination system of claim 13, wherein the spoilage determination system configures a single device. ### Claim 20 (depends on 13) The spoilage determination system of claim 13, further comprising a blower configured to produce a current of air which transports the volatile component to the detector, wherein a rate of the current is greater than or equal to 10 mL/min and less than or equal to 3000 mL/min.
