Hydroxypropyl starch vacant capsules and a process for producing them

Abstract

This present invention discloses hydroxypropyl starch vacant capsules and a process for producing them, wherein said hydroxypropyl starch vacant capsules are made of hydroxypropyl starch and water and optional light-screening agent, colorant, aromatics, and flavoring agent through the processes of raw material mixup, gelatinization, stabilization, and capsule-forming. The hydroxypropyl starch capsules disclosed in this invention have such advantages as extensive source of raw material, high safety level, disintegrating property and friability over the products prepared through existing technologies.

1 . A hydroxypropyl starch vacant capsule comprising hydroxypropyl starch in the amount of 80% to 95% by weight of the capsule, water in the amount of 5% to 15% by weight of the capsule, and an adhesive in the amount of 0% to 5% by weight of the capsule. 
     
     
         2 . (canceled) 
     
     
         3 . The hydroxypropyl starch vacant capsules according to  claim 1 , wherein said hydroxypropyl starch is one or a combination of hydroxypropylated starches selected from the group of hydroxypropylated starches derived from native mung beans starch, wheat starch, potato starch, cassava starch, soybean starch, or corn starch. 
     
     
         4 . The hydroxypropyl starch vacant capsules according to  claim 1 , wherein said adhesive is one or a combination of adhesives selected from the group of glycerol, polyethylene glycol, triethyl citrate, tributyl citrate, stearic acid, and propylene glycol;
 said light-screening agent, titanium dioxide;   said colorant, one or a combination of colorants selected from the group of Carmine, New Red, Amaranth, Allura Red, Erythrosine, Azorubine, Lemon Yellow, Sunset Yellow,Lactochrome, Canthaxanthin, Chlorophyll, Acid Green BS, Brilliant Blue, Patent Blue V, Cacao Husk Pigment, Ferric Oxide, Caramel, Carbon Nanotubes, and Brilliant black;   said aromatics, one or a combination of aromatics selected from the group of edible essence of different flavors such as apple, mint, orange, and pineapple; said flavoring agent, one or a combination of flavoring agents selected from the group of Sucrose, Mannitol, Xylitol, Sorbitol, Trehalose, Fructose, Maltose, Glucose, Steviosin, Sodium cyclamate, Acesulfame, Sucralose, and Aspartame.   
     
     
         5 . The hydroxypropyl starch vacant capsule& according to  claim 1 , wherein the hydroxypropyl starch vacant capsules are used in the preparation of capsule dosages for pharmaceuticals, foods, and dietary supplements. 
     
     
         6 - 13 . (canceled) 
     
     
         14 . A hydroxypropyl starch vacant capsule comprising hydroxypropyl starch in the amount of 80% to 95% by weight of the capsule, water in the amount of 5% to 15% by weight of the capsule, an adhesive in the amount of 0% to 5% by weight of the capsule, a light-screening agent, a colorant, an aromatic, and a flavoring agent,
 wherein the starch has a hydroxypropyl content of 2% to 7% by weight.
