Problems solved by technology

[0003] At present, there is no real commercial starch hollow capsule of pure plant origin on the market. The reason is that it is difficult for a single type of starch to achieve the comprehensive strength, toughness, disintegration within 10 minutes, and stability to the environment required by the hollow capsule. requirements, and the market lacks the supply of raw materials for the production of starch empty capsules, these factors have prevented the development and market launch of starch source empty capsules

Embodiment 1

[0037] Embodiment one: the preparation method of compound starch special glue, comprises the following steps:

[0038] 1) Raw material pretreatment: all raw materials are pulverized through a 100-mesh sieve and set aside;

[0039]2) Weighing: Weigh 3500g of acetate starch, 4000g of oxidized hydroxypropyl starch, 250g of hydroxypropyl starch, 600g of maltodextrin, 335g of κ-carrageenan, 825g of glycerin, and 105g of potassium chloride by weight percentage;

[0040] 3) Mixing: first mix a small amount of starch with maltodextrin, carrageenan, glycerin, and potassium chloride evenly, then add the rest of the starch according to the equal gradient addition method and mix evenly;

[0041] 4) Making soft materials and granules: using wet granulation technology, in a high-speed mixing granulator, spray the mixed raw materials with 50% ethanol aqueous solution to make soft materials, and pass through a 10-14 mesh sieve to obtain a particle size of 1 ~2mm wet particles;

[0042] 5) D...

Embodiment 2

[0043] Embodiment two: the method for preparing composite starch hollow capsules as a raw material with the special rubber particles obtained in embodiment one may further comprise the steps:

[0044] 1) Ingredients and sol: Weigh 12.95 kg of special rubber particles, disperse them into 20 kg of water, stir to obtain a starch emulsion, add the starch emulsion into 50 kg of boiling water in a trickle under constant stirring, stir evenly, and heat at 90°C Stir the glue until it becomes transparent. Take a certain amount of glue and dilute it to a glue with a solid content of 2%, and measure its light transmittance at 50°C and a wavelength of 500nm to be 82%;

[0045] 2) Degassing of gelatinization: After the sol is completed, degassing at a temperature of 50-65°C for 1-4 hours;

[0046] 3) Measure and adjust the viscosity: at 45-55°C, measure the viscosity of the glue to be 320-580mPa.S;

[0047] 4) Embryo making: Select a suitable type of capsule mold smeared with peanut oil,...

Embodiment 3

[0049] Embodiment three: the preparation method of composite starch special glue, comprises the following steps:

Abstract

The weight percent composition of the compound starch special glue disclosed by the present invention includes: 50-85% of starch, 1-6.5% of gelling agent, 0.1-5% of coagulant aid, 2-15% of plasticizing moisturizing agent, 0-15% of disintegrating agent 15%, food coloring 0~0.5%, sunscreen 0~3%. The special compound starch glue disclosed by the invention is a hollow capsule of plant origin, the main raw material of which is edible starch, and has good biocompatibility for human body. The compound starch empty capsule prepared by using the compound starch special glue of the present invention as a raw material has the advantages of one-time feeding, simple operation, short gelatin degassing time, adaptability to the gelatin hollow capsule production line, and avoiding the operator from being polluted by raw material dust. The water content of the empty capsules prepared from the compound starch special glue of the present invention is 7-11%, and it is not easy to absorb moisture, brittle, or grow microorganisms at normal room temperature and humidity, and does not need to add preservatives, which conforms to the national pharmacopoeia. According to the pharmaceutical index requirements, the compound starch hollow capsules are real plant-sourced hollow capsules, suitable for all kinds of people to take.

Description

technical field [0001] The invention relates to a hollow capsule and its preparation, in particular to a novel pure plant-sourced composite starch special glue with composite starch as a raw material and a method for preparing the hollow capsule thereof. Background technique [0002] Empty capsules are the most commonly used filling carriers for modern medicines, health products and dietary supplements. In my country, more than 95% of empty capsules are made of gelatin made from pig or cow skin and bone. Obviously, the scope of application of this type of hollow capsules is not as popular as that of plant-based raw materials. It is an inevitable trend for the development of this industry to replace animal-derived hollow capsules with plant-derived hollow capsules. To be popularized in the market, plant-derived empty capsules need to have: (1) good human compatibility and safety; (2) have the same product performance as gelatin empty capsules (such as disintegration, toughne...
