  • Patent number: 11965468
    Abstract: A vehicle control system, a vehicle control method, and a storage medium are provided. A stopping process stops fuel supply to one or more stopping cylinders and supplies fuel to one or more remaining cylinders during a load operation of an engine. During execution of the stopping process, a compensating process compensates for a decrease in output of the one or more stopping cylinders due to the execution of the stopping process by increasing output generated by combustion in the one or more remaining cylinders. The system control circuit causes, when the engine rotation speed of the engine is the same, the output after being increased by the compensating process to decrease as a shaft torque of the crankshaft of the engine increases.

  • Patent number: 7504119
    Abstract: In this application is disclosed a process for producing cheese curd characterized in that (a1) a milk-clotting enzyme is added to a raw material milk being kept at a low temperature where the milk protein is not coagulated by the milk-clotting enzyme, whereby the milk-clotting enzyme is allowed to react or work, a transglutaminase is then added, and the resulting mixture is raised in temperature and kept at the raised temperature, whereby the transglutaminase is allowed to react, or (a2) a milk-clotting enzyme and a transglutaminase are simultaneously added to a raw material milk being kept at a low temperature, and the resulting mixture is kept at the same low temperature for a period of time, during which the milk-clotting enzyme is mainly allowed to react, and the resulting mixture is raised in temperature and kept at the raised temperature, during which the transglutaminase is mainly allowed to react, (b) whereby raw material milk curdles, and the resulting coagulated milk is subjected to cutting, follow

  • Publication number: 20040131728
    Abstract: In this application is disclosed an improved enzyme preparation for binding solid food materials which comprises, as the active ingredient, a transglutaminase, and (1) a collagen in which the total of the residues of the hydroxyproline and proline in the collagen is less than 20% of the total of the amino acid residues in the collagen or/and (2) a collagen having an average particle diameter of smaller than 600 &mgr;m, which preparation is excellent in operability and provides high binding strength.

  • Patent number: 6749873
    Abstract: Herein is disclosed a cheese yield enhancing method in a cheese manufacturing method including a process of separating a cheese curd from a whey after a milk coagulating treatment of a material milk by a milk coagulating enzyme, said cheese yield enhancing method comprising steps of: adding/mixing a protein decomposing enzyme treated material of a milk whey protein (a partial hydrolysate of the milk whey protein) to the material milk; and subjecting a resulting mixture to the milk coagulating treatment by the milk coagulating enzyme, or said cheese yield enhancing method comprising steps of: adding/mixing a partial hydrolysate of a milk whey protein to the material milk; allowing transglutaminase to act on a resulting mixture; and subjecting the mixture to the milk coagulating treatment by the milk coagulating enzyme, whereby a yield of a cheese curd from a material milk, and therefore a yield of cheese may be enhanced and a cheese superior in quality may be manufactured.

  • Patent number: 6716461
    Abstract: Herein is disclosed a method for modifying raw material milk, wherein a reducing agent such as a thiol compound is added when transglutaminase is caused to act upon raw material milk for a dairy product, whereby the reactivity of the transglutaminase to the raw material milk such as raw cow milk, can be improved and the milk protein can, in turn, be modified effectively. From the thus-modified raw material milk can be produced dairy products such as yogurt, cheese and powdered milk improved in physical properties, mouthfeel or texture.

  • Patent number: 5736356
    Abstract: The present invention relates to a transglutaminase originating from Crassostrea gigas, a gene coding for the transglutaminase, a plasmid carrying the gene, a microorganism transformed with the plasmid, a method for producing an intended transglutaminase by cultivating the microorganism and a method for gelating a protein using the transglutaminase originating from Crassostrea gigas. When comparing with other transglutaminases, the transglutaminase originating from Crassostrea gigas has novel characteristic properties such that it can be activated by the action of calcium ions and that it is further activated by the addition of sodium chloride and/or potassium chloride and it is of utility value, in particular, as a gelling agent for foods.
