[0005] Chinese patent CN201410159754 discloses an adjuvant that can improve the properties of soft capsules, as well as an opacifier that can change the appearance and smell of soft capsules, using hydroxypropyl starch as the main raw material, and supplemented with gelling agent, softener and film-forming agent. The disadvantage of the starch-based rubber prepared from coloring agents and flavoring agents is that compared with other colloidal materials, the rubber mainly made of hydroxypropyl starch is more brittle, the elasticity and toughness of the rubber deviate, and the final pellets are broken. more likely
Chinese patent CN201210181762 discloses that pullulan polysaccharide is used as the main raw material, mixed with various biological polysaccharides or seaweed polysaccharides respectively, and formed into a film after several processes, and pressed into pills by a rotary film method soft capsule machine, which is characterized in that The prepared soft capsule pills can reach a level similar to gelatin in terms of transparency, elasticity and mechanical strength, and completely disintegrate within the relevant specified time. The disadvantage is that the price of pullulan is relatively high and the cost is expensive

Abstract

The invention relates to a vegetable soft capsule shell composition and a preparation method thereof. The composition comprises the following ingredients by content: 0-30% of hydroxypropyl starch, 0-20% of hydroxypropyl methyl cellulose, 0-20% of pullulan, 0.1-10% of one or more gels, 0.5-30% of one or more plasticizers, 0-5% of one or more soluble salts, 0-4% of an opacifier, 0-4% of one or more colorants and 10-90% of water, wherein the contents of hydroxypropyl starch, hydroxypropyl methyl cellulose and pullulan are not zero, and the total content is 100%. The preparation method comprises the following steps: adding hydroxypropyl starch into water for dispersion, so as to obtain a solution A; adding other ingredients except hydroxypropyl methyl cellulose into water for dispersion, so as to obtain a solution B; mixing the solution A with the solution B, heating to 90-95 DEG C, carrying out stirring and heat preservation for 0.5-2 hours, cooling to 75-80 DEG C, and carrying out heat preservation, still standing and defoaming to obtain a glue solution; measuring the viscosity of the glue solution after defoaming, wherein the composition is obtained when the viscosity reaches 20,000-30,000 mPa.s.

Description

technical field [0001] The invention relates to a soft capsule rubber composition, in particular to a vegetable soft capsule rubber composition and a preparation method thereof. Background technique [0002] Soft capsule refers to the liquid or molten drug mixture containing certain active ingredients, or the solution, suspension, emulsion or semi-solid (paste, etc.) mixture containing solid drug dispersed and dissolved, sealed in a spherical or oval shape. soft capsular capsules. The advantage of soft capsules is that the embedded contents are completely isolated from external factors such as air, so as to avoid the effective components in the contents from being destroyed by external factors; the volatile and easily oxidized components can be effectively maintained, and a single capsule particle The content or net content of each active ingredient can be maintained stable to ensure the medicinal and health care value of the content; it can effectively cover up the odor of...
