Plant mass cement for preparing hollow capsule, as well as hollow capsule of plant mass cement

Abstract

The invention relates to plant mass cement for manufacturing hollow capsules of foods, medicines and the like, and a hollow capsule which is prepared from the plant mass cement and can be quickly disintegrated. The plant mass cement for preparing the hollow capsule is prepared by mixing the following components in percentage by weight: 12-25 percent of hydroxypropyl methyl cellulose, 0.1-9 percent of hydroxypropyl starch or acidified hydroxypropyl starch, 0.4-2 percent of a gelatinizing agent and the balance of water, wherein the aqueous solution of the 2wt% hydroxypropyl starch at 20 DEG C has a viscosity of 3-7mpa.s; the substitution degree DS of the hydroxypropyl starch or acidified hydroxypropyl starch is in a range of 0.004-0.55. The plant mass cement is prepared by adopting a conventional capsule preparation process for preparing the hollow capsule can be used for preparing a hydroxypropyl methyl cellulose hollow capsule which can be quickly disintegrated.

Description

technical field [0001] The invention relates to a plant gum used for manufacturing hollow capsules used for food, medicine, etc., and a rapidly disintegrating hollow capsule prepared from the plant gum. Background technique [0002] Capsules made from animal-derived gelatin have been around for at least 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 time. At the end of the last century, the outbreak of mad cow disease finally dragged gelatin capsules into an unprecedented crisis of confidence. In April 2012, the "poisonous capsule" incident that broke out in my country undoubtedly aggravated the distrust of the Chinese people towards gelatin capsules. In addition, gelatin capsules themselves h...

AI Technical Summary

Problems solved by technology

Although the price of hydroxypropyl methylcellulose is not very expensive, the glue liquid material is relatively large in the production process of preparing hollow capsules, and it is difficult to remove water, and the glue paste thread is long and difficult to form. The capsules made of it as the main raw material have a long disintegration time limit, therefore, the current domestic market share is not high
