Abstract: A volatile component released from an epicarp of a banana or an avocado is collected. By using a detector, a detection result of the volatile component is obtained. The detector is configured to output the detection result in accordance with an amount of one or more marker components selected from the group consisting of specific compounds. Based on the detection result, the ripeness of the banana or the avocado is assessed.

Abstract: A volatile component released from a food product is trapped. 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.

Abstract: An air quality determination method including a temperature control step, an acquisition step, a determination step, and an output step. The temperature control step includes controlling a temperature of a sensitive unit exposed to a sample gas to cause the temperature of the sensitive unit to vary in a temperature variation pattern including at least one temperature rising period in which the temperature of the sensitive unit rises and at least one temperature falling period in which the temperature of the sensitive unit falls. The acquisition step includes acquiring an electrical characteristic value of the sensitive unit exposed to the sample gas. The determination step includes determining, using a learned model to determine an air quality condition of the sample gas, the air quality condition of the sample gas based on a variation in the electrical characteristic value. The output step includes outputting a decision made in the determination step.

Abstract: A gas sensor includes: a sensing unit; and a first electrode and a second electrode that are a pair of electrodes each electrically connected to the sensing unit. The sensing unit has a conductive material and a polymer having a siloxane bond as a main chain structure. The polymer has a cyano group in a side chain.
