Patents by Inventor Ryosuke Kiwata

Ryosuke Kiwata has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Acidic protein foods, process for their production and stabilizer
    Patent number: 6890578
    Abstract: Acidic protein foods employing pectin which has been low-molecularized to a viscosity of no greater than 150 mPa·s as a stabilizer for the acidic protein foods, wherein the pectin is added at greater than 0.4 wt % to the acidic protein foods. It is possible to achieve a wider stable pH range and improvement in palatable texture due to lower viscosity of the products.

  • Carboxylic acid and amino acid or amino condensate reactants and manufacturing method therefor
    Patent number: 6743945
    Abstract: The present invention relates to a method of manufacturing compoundable carboxylic acid and amino acid or amino acid condensate reactants by an extremely simple method that does not use substances toxic to human beings, as well as to carboxylic acid and amino acid or amino acid condensate reactants manufactured according to the method. In the present invention, carboxylic acid and amino acid or amino acid condensate reactants are manufactured by mixing carboxylic acids and amino acids or amino-acid condensates under an aqueous system and heating to 100° C. or more, less than 180° C. without vaporizing the water away.

  • Process for producing water-soluble polysaccharides, and method for clarifying water-soluble polysaccharide aqueous solutions
    Patent number: 6710176
    Abstract: By amylase treatment of water-soluble polysaccharide aqueous solutions extracted from legumes under acidic conditions, for hydrolysis of the starch substances that are a source of precipitates and suspended matter, it is possible to improve the clarity of the aqueous solutions while also preventing production of precipitates during long-term storage or cold storage of the aqueous solutions.
