  • ALCOHOL-CONTAINING WASABI, WASABI EXTRACT SOLUTION AND WASABI EXTRACT
    Publication number: 20080311275
    Abstract: The present invention provides an alcohol-containing wasabi, a wasabi extract solution and a wasabi extract capable of stably maintaining flavor and pungent taste of freshly harvested wasabi for a long period of time. The alcohol-containing wasabi is prepared by impregnating wasabi with alcohol. The method for obtaining the alcohol-containing wasabi comprises the steps of impregnating the mass of wasabi with alcohol by permitting wasabi to contact alcohol or an alcohol aqueous solution, and allowing wasabi to stand for 20 minutes or more at a temperature from 5 to 60° C. The wasabi extract solution is obtained by distilling of the alcohol-containing wasabi. The wasabi extract is obtained by diluting the wasabi extract solution with water to an alcohol concentration of 30% by weight or less to form precipitates, and by filtering the precipitate.

  • Water-insoluble glucan purification method
    Patent number: 5795979
    Abstract: The present invention relates to a water-insoluble glucan purification method characterized in that a culture solution of a microbe that produces water-insoluble glucan or a microbial cell-containing solution comprising water-insoluble glucan as a component is treated with both an oxide of 0.175-3.5 wt.--wt. % and a hydroxide such that the pH value becomes 10-12.5. Since the present invention accomplishes all of the destruction of production microbe, the decolorization and the reduction of viscosity of a culture solution of a microbe that produces water-insoluble glucan or a microbe cell-containing solution comprising water-insoluble glucan as a component, the invention purifies water-insoluble glucan industrially at low costs and with a high efficiency.

  • Process for producing a polyene antibiotic
    Patent number: 5244661
    Abstract: By irradiating a polyene antibiotic having a cis-type polyene structure with long wavelength ultraviolet light, it is possible to prepare the corresponding antibiotic having a trans-type polyene structure in high yield in a simple manner. Such antibiotics having a trans-type polyene structure exhibit strong antimicrobial activities and are useful as drugs for humans or animals.
