Problems solved by technology

[0003] However, currently commercially available gelatin hollow capsules, the basic components include gelatin, glycerin and water; gelatin is a kind of protein material obtained by hydrolysis of animal skin and bone; and the "mad cow disease" that has swept across Europe in recent years, It also had an impact on the traditional capsule market. The US FDA believes that gelatin should be removed from the list of conventional safe foods; Buddhists, Muslims and vegetarians will not accept this animal-based gelatin for reasons of religion or belief. Capsules; in addition, in China, some people even use industrial gelatin produced by leather base glue to prepare hollow capsules, which makes the quality of traditional gelatin hollow capsules have many safety hazards

Abstract

The invention relates to a preparation method of a gelatine-free double-layer hollow capsule. The preparation method is characterized by comprising the following steps of: by taking microbial polysaccharide gum, algal polysaccharide gum and plant polysaccharide gum as raw materials; and mixing, dissolving the gums, degassing, dipping the gums, drying, dipping the gums again, drying again, shelling, cutting and trimming, so as to prepare the gelatine-free double-layer hollow capsule, wherein the inner layer of the capsule contains pullulan and sodium alginate, and the outer layer of the capsule contains hydroxypropyl methyl cellulose and methylcellulose. With the adoption of the double-layer structure, the disintegration performance of the capsule can be greatly improved, and the good mechanical strength of the whole capsule can be kept. The product can be used for filling various medicines and healthcare foods by taking the microbial polysaccharide gum, the algal polysaccharide gum and the plant polysaccharide gum as the raw materials and avoiding the use of any gelatine ingredient; the product is safe, reliable, and is suitably eaten by Buddhist, Moslems and vegetarian; and the worry of people about eating for gelatine products caused by 'bovine spongiform encephalopathy' is avoided.

Description

technical field [0001] The invention relates to a preparation method of a gelatin-free double-layer hollow capsule, which belongs to the technical field of hard capsule processing. Background technique [0002] At present, conventional hollow capsules are composed of a cap and a body, which are refined from medicinal gelatin and auxiliary materials. They are mainly used to hold solid medicines, such as self-made powders, health products, medicines, etc. , the problem of poor taste has truly realized that good medicine is no longer bitter; hollow capsules are becoming more and more popular. First of all, the shape of capsules is slender and easy to swallow, which is the most popular dosage form for consumers; in addition, capsules can effectively cover up Unpleasant taste and odor of the contents; Capsules come in a variety of sizes, including size 00 extended and size 5 capsules. Capsules can also be printed with words, logos and patterns to present a unique customized appe...
