A detection method for origin determination is provided. A gas chromatography-ion mobility spectrometry (GC-IMS) technology is adopted to obtain GC-IMS diagrams by detecting types and contents of volatile organic compounds in fruits. After analysises, fingerprint diagrams and principal component analysis (PCA) diagrams of the volatile organic compounds in the fruits are obtained. Origins of fruits can be determined based on the fingerprint diagrams and the PCA diagrams. By datumizing the traditional smelling method, it can assist scientific researchers and producers or businesses to identify origins or specific producing areas of fruits.

The invention relates to a rapid method for estimating the dry matter content of a fruit or vegetable. The method comprises drying a sample of the fruit or vegetable on a support and measuring the dry matter content, wherein the whole method can be carried out in less than 2 hours. This compares to the industry standard method for assessing dry matter in horticultural products which typically takes 6-48 hours.

An information processing system includes a storage, an interface device, and a computing circuit. The storage stores a database, in which spectrum data concerning light from a light source and a measurement condition data at a time of measurement of the light are associated with a plant status data concerning growth of a plant and/or a harvest data concerning a harvest of the plant. The interface device receives an input of a user measurement condition which is to be applied at a time of measurement of the plant by a user and which includes data concerning angles at the time of measurement and data concerning a plant status and/or a harvest to be predicted. The computing circuit determines at least two wavelengths contained in the light from the light source to be measured under the user measurement condition by referring to the database based on the user measurement condition.

A gas sensor system (100) for detecting conjugated hydrocarbons and/or esters in an environment. The gas sensor system includes two organic thin film transistor (OTFT) gas sensors (200, 300). The first OTFT gas sensor (200) allows for interaction of the conjugated hydrocarbon with the gas sensor's source and drain electrodes, and the second OTFT gas sensor (300) blocks the conjugated hydrocarbon from interacting with the gas sensor's source and drain electrodes. In the second gas sensor, a monolayer comprising 4-aminobenzenethiol and 4-fluorobenzenethiol may cover the source and drain electrodes preventing the conjugated hydrocarbon from interacting with the source and drain electrodes. The gas sensor system may be used to monitor a volatile conjugated hydrocarbon and/or an ester produced by fruit.
