Abstract
The present invention provides a film composition containing caramel (Caramel I, II, III or IV) as a brown colorant, particularly a film composition containing a water-soluble cellulose derivative as a base component and suitably used for a capsule base, the film composition ensuring high degree of transparency because of the suppression of caramel aggregation. The present invention also provides a method for preparing the brown film composition. The present invention is enforced by adjusting pH of an aqueous solution in forming a film composition, which is obtained by solidification of an aqueous solution containing a water-soluble cellulose derivative and caramel, to a predetermined range using a pH adjuster.
