  • Publication number: 20100086643
    Abstract: To provide a tomato juice-containing alcoholic drink that has improved flavor qualities and shows regulated sedimentation and color change and a method of the production of the same. Provided is a method of the production of a tomato juice-containing alcoholic drink that comprises the following steps (a) to (c): (a) a step of producing a lactic acid-fermented tomato liquid that comprises fermenting a tomato juice-containing liquid by using a lactic acid bacterium and thus increasing lactic acid in the liquid; (b) a step of producing a clear tomato juice that comprises enzymatically treating a tomato juice and filtering the same; and (c) a step of mixing the lactic acid-fermented tomato liquid, the clear tomato juice and an alcohol; optionally followed, if desired, by the following step (d), (d) a step of adding stabilized lycopene.

  • Patent number: 6573321
    Abstract: An anti-contamination coating composition is obtained by mixing a tetraalkoxysilane condensate having an average condensation degree of 4 to 20 and has an alkyl group having 1 to 2 carbon atoms and an alkyl group having 3 to 10 carbon atoms, or an alkyl group having 1 to 3 carbon atoms and an alkyl group having 4 to 12 carbon atoms, the alkyl group having 3 to 10 carbon atoms or 4 to 12 carbon atoms present in the amount of 5 to 50% by equivalent based on all alkyl groups in the condensate, with a polyurethane resin, an acrylic copolymer resin or a silicone-acrylic copolymer resin in the amount of 1.0 to 40.0 parts by weight in term of SiO2 relative to 100 parts by weight of the polyol compound. The addition of a hydrophilic alkoxysilane having a poly alkylene oxide chain compound is also suitable.

  • Patent number: 6271293
    Abstract: The present invention relates to a coating composition, which forms an anti-contamination coat having hydrophilicity on the surface, soil-release effect and excellent stain resistance to oil, and which is also suitable for outside wall coating of buildings, having excellent interlaminar adhesion when multiple coating is performed. A conventional anti-contamination coating was insufficient in stainproofing performance immediately after formation of the coat, and there was no coating which is superior in stain resistance to oil and interlaminar adhesion.
