Problems solved by technology

Although the price of hydroxypropyl methylcellulose is not very expensive, in the production process of preparing hollow capsules with it as the main raw material, the glue water material is relatively large, and it is difficult to remove water, and the glue paste is long and difficult to form. Large, the disintegration time of hollow capsules prepared with it as the main raw material is relatively long, therefore, the current domestic market share is not high
The price of starch is very low, and it is very attractive to prepare hollow capsules with it. Many domestic manufacturers have also applied for patents for starch hollow capsules. However, because starch molecules are easy to form strong hydrogen bonds, the starch film is brittle and fragile. It is difficult to make hollow capsules with high strength and resistance to filling
In recent years, some American and Japanese patents have prepared hollow capsule shells with higher strength by adding high-strength gels to the starch matrix, but at the same time, it has also caused the hollow capsule shells to be difficult to disintegrate, and it is difficult to obtain rapid disintegration in the body. product
Therefore, although there are many patents, there is no product that can be pushed to the market so far.

Abstract

The invention relates to preparation of hollow capsules used in the fields of foods, medicines and the like, in particular to a raw material composition for preparing starch-based hollow capsules, andthe starch-based hollow capsules which are prepared from the raw material composition and are liable to disintegrate quickly. The raw material composition is prepared by mixing hydroxypropyl starch,hydroxypropyl-beta-cyclodextrin and a gelatinizing agent. The starch-based hollow capsules can be prepared by mixing the raw material composition with water, heating, gelatinizing and gelatinizing. According to the composition, a proper amount of the hydroxypropyl-beta-cyclodextrin with excellent water solubility is introduced into the raw material composition, so that the prepared starch-based hollow capsules have good disintegration performance, and the strength of the capsules is not influenced.

Description

[0001] This application is a branch of the Chinese invention patent application submitted by the applicant to the State Intellectual Property Office on September 19, 2014. case application. technical field [0002] The invention relates to the manufacture of hollow capsules used in the fields of food, medicine and the like, in particular to a raw material composition for preparing starch-based hollow capsules, and a starch-based hollow capsule that is easily and rapidly disintegrated prepared from the raw material composition. Background technique [0003] The use of animal-derived gelatin to make hollow capsules has a history of at least nearly 200 years. Since gelatin can mask the bad taste, smell or irritation to the stomach of many medicines, gelatin capsules are quickly promoted and used in the production of various solid preparations. Over the past 100 years, various capsules made of gelatin have been sold well in the international pharmaceutical market for a long tim...
