Disclosed are an aqueous composition for enteric hard capsules, a production method for enteric hard capsules and enteric hard capsules. The aqueous composition for the disclosed enteric hard capsules comprises an enteric base material, a capsule-moulding adjuvant and a neutralizing agent. Additionally, the production method for the disclosed enteric hard capsules comprises the steps of: producing an aqueous composition by dissolving an enteric base material, a capsule-moulding adjuvant, a neutralizing agent and other additives in water; pre-heating the aqueous composition to a temperature lower than its gelatinization temperature; immersing a mould pin, which has been heated to a temperature higher than the gelatinization temperature, into the aqueous composition; obtaining a film which has been formed on the mould pin by recovering the mould pin from the aqueous composition; and fixing and then drying the film on the mould pin by maintaining the film at a temperature at or above the gelatinization temperature for a predetermined time. |
