Abstract:
Provided are a method for manufacturing a chlorogenic acid-containing composition, including a chlorogenic acid extraction step of obtaining a chlorogenic acid-containing liquid extract from sunflower seed residues remaining after oil expression by bringing chlorogenic acid and saccharides derived from the sunflower seed residues remaining after oil expression into contact with yeast and a solvent selected from the group consisting of water, an alcohol, and a liquid mixture of water and an alcohol, and a bacterial treatment step of performing at least one treatment selected from germicidal treatment or sterilization treatment on the liquid extract, a chlorogenic acid-containing composition obtained by the manufacturing method, and a drink or food item containing the chlorogenic acid-containing composition.
Abstract:
A gas detection method using a gas detection element obtained by laminating a fixed support, a first electrode (2), a dielectric sensor (3), a second electrode (4), and a gas adsorption film (5), in this order, the method including: a step of applying a first signal resonantly driving the dielectric sensor (3) between electrodes of the first electrode (1) and the second electrode (3), and detecting gas adsorbed on the gas adsorption film based on a change of a resonant frequency of the dielectric sensor; and a step of heating the dielectric sensor (3) by applying a second signal between the electrodes after the detection of gas and desorbing gas adsorbed in the gas adsorption film; a gas detection system capable of performing the method; and a gas desorption method appropriate for applying this gas detection method.
Abstract:
Provided are an insect detection method that includes detecting an intrinsic gas emitted by an insect using a gas sensor including a gas adsorption membrane, the gas sensor being selected from a resonant sensor, an electrical resistance sensor, and a field effect transistor sensor; a gas sensor for insect detection and a gas sensor array for insect detection, which are suitable to be used for this method; and an electric machine product having the gas sensor or gas sensor array mounted therein.
