Problems solved by technology

[0003] Our country needs about 250 billion medicinal capsules every year, and more than 95% of them are animal gelatin capsules. It has been found that, for example: 1. Gelatin is easy to cross-link with drugs such as aldehydes, reducing sugar-based compounds and vitamin C, which makes the water solubility of capsules worse, leading to the disintegration of empty capsules and the delay of dissolution of capsule contents; Electrostatic charge accumulation can occur under dry conditions, which greatly affects subsequent production and processing; 3. When stored in a low-humidity environment for a long time, gelatin capsules tend to become brittle and cause the capsules to break; 4. Gelatin is an animal-derived component. factors, thus making gelatin rejected by certain groups of people in the world

Embodiment 1

[0028] A hydroxypropyl starch hollow capsule, in parts by weight, the hydroxypropyl starch hollow capsule comprises the following components: 100 parts of hydroxypropyl starch, 15 parts of konjac gum, 2 parts of potassium chloride, 0.5 parts of glycerin, nano 0.8 parts of superfine calcium carbonate, 1000 parts of pure water.

[0029] A preparation method for hydroxypropyl starch hollow capsules, comprising the following steps:

[0030] (1) Mixed sol: mix hydroxypropyl starch, gelling agent, and coagulant aid with water in proportion, stir evenly and put it in a water bath set at 70°C to 80°C to gelatinize the starch, keep warm while stirring , After 70-100 minutes, take it out and cool down, add glycerin and nano-ultrafine calcium carbonate, stir evenly to form a glue, and let it stand for 120-160 minutes to remove the air bubbles in the glue.

[0031] (2) Dip in glue to make a blank: put the glue in a fully automatic hollow capsule manufacturing machine, and dip the die rod...

Embodiment 2

[0037] The difference between this example and Example 1 is that the hydroxypropyl starch hollow capsule includes the following components: 105 parts of hydroxypropyl starch, 22 parts of carrageenan, 2 parts of potassium chloride, 1 part of glycerin, nanometer super 1 part of fine calcium carbonate, 1100 parts of pure water.

Embodiment 3

[0039] The difference between this example and Example 1 is that the hydroxypropyl starch hollow capsules include the following components: 110 parts of hydroxypropyl starch, 25 parts of konjac gum, 3 parts of potassium chloride, 1.5 parts of glycerin, nanometer super 1.5 parts of fine calcium carbonate, 1200 parts of pure water.

Abstract

The invention discloses a hydroxypropyl starch empty capsule, which is prepared from the following components (by weight): 100-110 parts of hydroxypropyl starch, 15-25 parts of gel, 2-3 parts of coagulant aids, 0.5-1.5 parts of a plasticizer, 0.8-2 parts of nanometer superfine calcium carbonate and 1000-1200 parts of water. Meanwhile, the invention further discloses a preparation method of the hydroxypropyl starch empty capsule. The empty capsule prepared by the preparation method has high toughness, is not easy to break and has good stability; in addition, the raw materials are cheap in price, the cost is low, and there is no environmental pollution in the production process.

Description

technical field [0001] The invention relates to the technical field of starch modification, in particular to a hydroxypropyl starch hollow capsule and a preparation method thereof. Background technique [0002] Ordinary capsules can be divided into hard capsules and soft capsules, and hard capsules are also called "hollow capsules". The hollow capsule is composed of a cap and a body two-section capsule shell refined from gelatin and auxiliary materials. It is mainly used to hold solid and liquid medicines. , Capsules can also effectively mask the unpleasant taste and smell of the contents, and are the most popular dosage form for consumers. [0003] Our country needs about 250 billion medicinal capsules every year, and more than 95% of them are animal gelatin capsules. It has been found that, for example: 1. Gelatin is easy to cross-link with drugs such as aldehydes, reducing sugar-based compounds and vitamin C, which makes the water solubility of capsules worse, leading t...
