  • Patent number: 8603552
    Abstract: A method for producing a food product containing nattokinase but containing little or none vitamin K2, comprising treating a Bacillus natto culture or culture supernatant with at least one coagulant selected from the group consisting of an inorganic coagulant and a cationic polymer coagulant (excluding chitosan). As the inorganic coagulant, calcium chloride or poly aluminum chloride is preferable, and their mixtures with a phosphorus coagulant are also preferably used. As the cationic polymer coagulant, cationic polysaccharides, hexamethylenediamine/ephichlorohydrin polycondensates or dimethylamine/epichlorohydrin polycondensates are preferably used, and their mixtures with a polyacrylate are also preferably used.

  • Patent number: 8114642
    Abstract: A method for producing vitamin K2 comprising: culturing Bacillus natto in a liquid medium to obtain a Bacillus natto culture or culture supernatant thereof, wherein the culture or culture supernatant contains vitamin K2; treating the culture or culture supernatant with at least one coagulant selected from the group consisting of an inorganic coagulant and a cationic polymer coagulant, with the proviso that the coagulant excludes chitosan, so as to obtain a treated coagulant to which vitamin K2 is absorbed or aggregated; separating the treated coagulant from the treated culture or culture supernatant, and obtaining an oily product that contains vitamin K2 from the separated coagulant.

  • Publication number: 20090136648
    Abstract: It is intended to provide a platelet aggregation inhibitor which can be easily processed into a pharmaceutical preparation and can be stored for a long time, and a health food effective in inhibiting platelet aggregation. The platelet aggregation inhibitor comprises, as an active ingredient, a degradation product obtained by reacting fibrin with nattokinase, wherein the degradation product has a molecular weight of 10,000 daltons or less. The fibrin is obtained by reacting fibrinogen with thrombin.
