Hydroxypropyl starch for preparing empty capsules and hydroxypropyl starch-based soft capsules

This invention comprising in hydroxypropyl starch for preparing empty capsules in alimentary and medical use, and hydroxypropyl starch-based soft capsules. This invention takes water as solvent, mix with propylene epoxide and catalyst for reaction, after washing, drying, hydroxypropyl starch is completed. The MS level of substitution of starch is around 2˜5, gelatinization point between 25˜60° C. After the hydroxypropyl starch is gelatinized by heating in water, a hydroxypropyl starch matrix soft capsule can be prepared. The invention consists in introducing hydroxypropyl by modifying the molecular chain of starch to improve the flexibility and hydrophilicity of starch. Therefore, a hydroxypropyl starch matrix soft capsule capable of preparing a flexible and disintegrating property is provided.
