Non-gelatinous capsule shell composition and a capsule formed from the same
Non-gelatinous capsule film compositions containing as the base a starch hydrolyzate having an average DE of less than 10 and an average molecular weight of not more than 30,000. These non-gelatinous capsule film compositions have stable moisture absorbing/releasing properties and strength to such extent as sufficiently withstanding the production and storage as products and yet achieve excellent disintegration properties in vivo. Also, capsules produced by using the non-gelatinous capsule film compositions as described above are provided.
1. A non-gelatinous seamless capsule comprising a content and a capsule shell encapsulating the content, wherein the capsule shell comprises (a) a soluble starch or dextrin having an average dextrose equivalent DE of less than 10 and an average molecular weight of not more than 30,000 and (b) a gelling agent being a polysaccharide which melts at a temperature of not more than 80° C., and the seamless capsule is obtained by a dripping process using a multiple nozzle.
2. The non-gelatinous seamless capsule according to claim 1 , wherein the soluble starch or dextrin (a) is contained in an amount of not less than 50%, based on total weight of a composition for the capsule shell.
3. The non-gelatinous seamless capsule according to claim 1 , wherein the gelling agent is a polysaccharide, which is one or combination of two or more selected from the group consisting of furcellan, carrageenan, LM pectin, curdlan, psyllium seed gum, mixture of xanthan gum and locust bean gum, mixture of xanthan gum and guar gum, mixture of xanthan gum and guar gum hydrolyzate, and gelled starch.
4. The non-gelatinous seamless capsule according to claim 1 , wherein the gelling agent is carrageenan, and a weight ratio of one or combination of two or more selected from the group consisting of furcellan, LM pectin, curdlan, psyllium seed gum, mixture of xanthan gum and locust bean gum, mixture of xanthan gum and guar gun, mixture of santhan gum and guar gum hydrolyzate, and gelled starch to the carrageenan is 6:4 to 9:1.
5. The non-gelatinous seamless capsule according to claim 1 , wherein the gelling agent is one or combination of two or more selected from the group consisting of acid hydrolyzed starch and white dextrin.
6. The non-gelatinous seamless capsule according to claim 1 , wherein the gelling agent comprises a gelation aid.
7. The non-gelatinous seamless capsule according to claim 6 , wherein the gelation aid is one or combination of two or more selected from the group consisting of a potassium ion, a sodium ion, a calcium ion and an aminonium ion.
8. The non-gelatinous seamless capsule according to claim 1 , wherein the gelling agent comprises a shell reinforcer.
9. The non-gelatinous seamless capsule according to claim 8 , wherein the shell reinforcer is one or combination of two or more selected from the group consisting of monosaccharides, disaccharides, oligosaccharide, polysaccharides and sugar alcohol.
10. The non-gelatinous seamless capsule according to claim 8 , wherein the shell reinforcer is a non-gelled polysaccharide, which is one or combination of two or more selected from the group consisting of pullulan, trehalose, gum arabic, arabinogaractan, cellulose and derivatives thereof.
