Abstract

The invention provides a pullulan and starch plant enteric capsule and a preparation method thereof; based on the pullulan and the starch, due to the advantage that the pullulan is good in water locking performance, the defect that the starch is poor in water locking performance and prone to embrittlement is overcome, the prepared enteric capsule is convenient to dry, and meanwhile, reasonable moisture content is kept in the long-time storage and transfer process, and cracking is prevented; since the pullulan and starch both have the problem of insufficient toughness, the problem can be well solved by adding hydroxypropyl methylcellulose; in addition, the enteric pore-foaming agent with the core material wrapped in the wall material is adopted, the wall material is made of a slow materialwith poor enteric solubility; when calcium salt or sylvite is released after the capsule is decomposed in the intestinal tract and is easily dissolved in water, the calcium salt can react in an alkaline environment and form pores quickly, and quick release of drug properties is facilitated.

Description

Technical field [0001] The present invention relates to the field of enteric solvent, and more particularly to a propullan poly sugar, a starch plant enteric capsule and a preparation method thereof. Background technique [0002] The current hollow capsule is mainly based on gelatin as the main raw material, gelatin is an animal's skin, bone, tendon and ligament of collagen not fully acid hydrolysis, alkali hydrolysis or enzyme-degradation purification, has good crisp, collapse Device and other performance, so it is widely used in the current capsule market, but the gelatin material has a certain problem, which mainly comes from the mammal, there is a risk of carrying viruses; and high water content, temperature and humidity Sensitive, when in high humidity, high temperature, there is aldehyde substance or an ultraviolet irradiation, it may also occur, and the crosslinked gelatin is not easily dissolved in water, which will affect the disintegration and dissolution of the capsule...
