摘要：
An aqueous composition for an enteric hard capsule, a method of preparing an enteric hard capsule, and an enteric hard capsule prepared using the method. The aqueous composition for an enteric hard capsule includes an enteric base material, a capsule forming aid, and a neutralizing agent. The method of preparing an enteric hard capsule includes: preparing an aqueous composition by dissolving an enteric base material, a capsule forming aid, and a neutralizing agent in water； preheating the aqueous composition to a temperature that is less than the gelation temperature for the aqueous composition； immersing a mold pin heated to a temperature that is greater than the gelation temperature for the aqueous composition into the aqueous composition； taking the mold pin out of the aqueous composition to obtain a film formed on the mold pin； and maintaining the film at a temperature that is equal to or greater than the gelation temperature for the aqueous composition for a predetermined period of time to fix the film on the mold pin and drying the film.
