The problem of this invention is to provide a gelatin capsule, wherein insolubilization of a capsule coating with the lapse of time is prevented, said insolubilization being brought about by the aldehydes derived from capsule packing materials or additives to raw materials for forming a capsule coating, and simultaneously mechanical strength reduction is minimized, as well as a novel gelatin composition for forming a gelatin coating which is used for the preparation of the capsule. [Means to Solve the Problem] By using as a raw material a gelatin composition which is prepared by blending a low molecular weight gelatin (a decomposition product of gelatin with a molecular weight of 6,000-26,000) with a common gelatin at 5-10 percent by weight in terms of a total amount of gelatin, hard or soft capsules are prepared in a conventional manner, thereby providing capsules which maintain mechanical strength and are difficult to be insolubilized. |
