| abstract |
A novel molded article exhibiting a gradual disintegration effect is prepared with pullulan. The effect is imparted by incorporating heteromannan into a pullulan molded article in an amount not exceeding the weight of the pullulan used. Galactomannans (e.g. guar gum, tara gum, and locust bean gum) and glucomannans (e.g. konjak mannan) are feasible as the heteromannan. The molded article is advantageously usable for industrial materials, pharmaceuticals, consumers' products, etc. |
