When sugared Kamaboko is incubated for a couple of days at 25°C, the sucrose decreases rapidly, but the reducing sugar increases rather to some extent. At the end of incubation period, the sucrose and reducing sugar concentrations become extremely low. As reducing sugar increases, some slimy carbohydrate polymer are produced on the surface of Kamaboko. This reaction is considered as a polymeric decomposition. The slime shows an acid reaction to Litmus paper. The isolated slime, purified several times by alcoholic precipitation, does not reduce FEHLING'S solution, but its hydrolyzate with HCl does so strongly. Furthermore, a striking similality is found between this polymer and pure dextran which is used as substitute blood plasma. From these facts, it is natural that the transparent, acid-nature slime is produced more abundantly by adding dissaccharide than by adding monosaccharide, certainly because of the fact that anhydro sugar units can only be utilized for the synthesis of new glycosidic bonds. The dextran seems to be fairly related to the slime or "Neto" of the sugared Kamaboko.
