Abstract

The invention relates to a film forming composition for producing a soft starch material capsule and a preparation method of the film forming composition, and the soft starch material capsule prepared from the film forming composition. The composition is formed by hydroxypropyl starch and water which are in a certain proportion, wherein optionally, proper auxiliary materials such as an opacifying agent, a colorant and a flavouring agent which are used for improving the performance of the soft capsule can be added. The preparation method comprises the following steps: mixing the materials according to a certain sequence; and controllably heating the materials in a temperature rising manner so as to obtain the film forming composition. The film forming composition can be directly produced so as to obtain the soft starch material capsule by indiscriminately using a production method of the traditional soft gelatin capsule.

Description

technical field [0001] The invention discloses a composition for preparing starch material soft capsules, a preparation method thereof, and a starch-based soft capsule prepared by the composition, and relates to the field of biomedicine. Background technique [0002] Capsules are a kind of pharmaceutical dosage form of modern medicine with wide uses and varieties. Capsules are widely used by various medical research institutions and institutions because of their simple prescription research, short development cycle, simple preparation process, and easy preparation of sustained and controlled release dosage forms. Favored by pharmaceutical companies. [0003] The capsule shell of traditional capsules is made of gelatin. Gelatin is a non-biologically active collagen hydrolyzate obtained by boiling animal skin and bone. It swells in cold water and dissolves into a glue in hot water. For a long period of time, almost all capsule shells on the market are made of gelatin. Even t...
