  • Publication number: 20190277796
    Abstract: A sensor includes a pump cell and a reference cell generating voltage Vs or current. The pump cell includes a pump cell first electrode and a pump cell second electrode. The surface of the pump cell first electrode includes a noble metal region formed of a noble metal, a ceramic region, and a coexistence region in which the noble metal and the ceramic material coexist. The width of the coexistence region in an A region of the surface of the pump cell first electrode is greater than the width of the coexistence region in a B region of the surface. The A region is a region close to the reference cell first electrode, and the B region is a region located further away from the reference cell first electrode as compared with the A region.

    Abstract: A gas sensor element configured to detect a first component and a second component of a measurement target gas comprises an element body portion, a first detection portion, a second detection portion with a porous region, and an element protection portion. The element protection portion covers the porous region and a region at the front side with respect to the porous region in a normal side face, and covers a part of a region at the front side with respect to the second detection portion without covering the second detection portion in a second detection side face. The element protection portion is formed so as not to cover the second detection portion but to cover the porous portion of the first detection portion.

  • Publication number: 20130309388
    Abstract: [Problem] Provided is a material that is capable of suppressing the loss of carbonation in a carbonated beverage over time to reduce changes in flavor, including mouthfeel, when drinking the beverage. [Solution] Addition of a water-soluble soybean polysaccharide into a non-alcoholic carbonated beverage suppresses the loss of carbonation over time to retain carbonation in the carbonated beverage for a long period of time, thereby reducing changes in flavor during a period from immediately after opening the container thereof to when drinking the beverage after storage.

  • Patent number: 8129501
    Abstract: Disclosed is gluten having good dispersibility in water. Also disclosed is a method for producing active gluten, a gluten-containing food or a gluten gel efficiently by using a gluten dispersion solution. Further disclosed is a method for producing a gluten hydrolysate efficiently by preparing a gluten dispersion solution in a simple manner and hydrolyzing the dispersion solution. Gluten, which normally forms an aggregate in water, can be dispersed readily by mixing gluten with a water-soluble polysaccharide containing galacturonic acid. The gluten dispersion solution thus prepared can be used to produce active gluten, a gluten-containing food or a gluten gel efficiently, and can be also used to prepare a gluten hydrolysate in a simple manner, efficiently and stably.

  • Publication number: 20090131699
    Abstract: It is intended to provide a method of practically obtaining a natural antioxidant, which gives a sense of security to consumers when added to foods, by efficiently taking out an antioxidant component from soybeans. It is confirmed that a hot water extract obtained by extracting a soybean seeds with hot water at a high temperature exceeding 100° C. under weakly acidic conditions has an antioxidant effect. A low-molecular weight fraction of this hot water extract is further fractionated by taking advantage of a difference in solubility in a water-containing organic solvent or using an appropriate filter suitable for the molecular weight size to thereby efficiently give a highly antioxidant fraction.

  • Publication number: 20060165866
    Abstract: Legume-derived, and particularly soybean-derived, water-soluble polysaccharides are added to thickener-containing powder supplied with an instant food to prevent clumping of powder masses during reconstitution and for a more homogeneous reconstitution. Thus, the problem is solved which is encountered with soup powders such as a thickened soup powder and a curry-seasoned soup powder, which are supplied with instant foods such as instant noodles, containing thickeners such as starch or gum substances to impart thickness, whereby reconstitution in a stationary state produces swelling of the thickener and prevents adequate dispersion, resulting in scattering of powder masses in the soup and clumping at the bottom of the container and, thereby, impairing the taste.
