PURPOSE:To obtain a raw material reduced in bitter taste, having excellent absorption-suppressing action of sugar in intenstinal tract, insoluble glucan production-inhibiting action, etc., and suitable for healthy food and medicine by adding and absorbing chitosan into extract of Gymnema Sylvestre. R. Br. CONSTITUTION:Dried leaf of Gymnema Sylvestre. R. Br. (hereinafter referred to as GS) is extracted with water or water-containing ethanol and the extracted liquid is concentrated and, as necessary, dried and pulverized. The chitosan obtained by deacetylating chitin contained in crab, lobster, etc., is added to the resultant extracted material and bitter taste ingredient of Gymnema Sylvestre. R. Br. extracted material is absorbed into chitosan to reduce bitter taste in the extent without hindrance on taste. Furthermore, amount of chitosan added is preferably about 100 to 700 pts.wt. based on 100 pts.wt. (expressed in terms of solid content) of GS extracted material. The resultant raw material composition is preferably used as a raw material for cake, bread, SOBA (buckwheat noodle), instant soap or other healthy food or various kind of medicines orally administered. |
