Abstract: This present invention discloses hydroxypropyl starch vacant capsules and a process for producing them, wherein said hydroxypropyl starch vacant capsules are made of hydroxypropyl starch and water and optional light-screening agent, colorant, aromatics, and flavoring agent through the processes of raw material mixup, gelatinization, stabilization, and capsule-forming. The hydroxypropyl starch capsules disclosed in this invention have such advantages as extensive source of raw material, high safety level, disintegrating property and friability over the products prepared through existing technologies.

Abstract: The invention discloses a technical process to prepare a self-reinforced starch composite used to produce capsules. This composite is made by uniformly mixing the matrix phase and the particulate reinforced phase at a proper proportion, the former being one or a combination of the starches selected from the group consisting of oxidized starch, cationic starch and esterified starch; and the latter, cross-linked starch or starch nanocrystals. This composite is processed into the forms of granules, films, or sheets by extrusion method and these different forms of the composite can be used to replace the gelatin as the raw material of capsules because its barrier property, processability, and mechanical properties are significantly improved.

Abstract: This present invention relates to a film-forming composite used to make starch softgel capsules and the method to prepare it. The said composite is made from water and hydroxypropyl starch by specific percentage, plus (optional) light-screening agent, colorant, and flavoring agent. Mix up the above components in sequential order and then process the mix into film-forming composite through controlled heating. The composite such made can be directly used to make starch softgel capsules by the conventional method applied for the gelatin capsule production.
