Abstract

The invention discloses a modified starch plant capsule and a preparation method thereof, belonging to the technical field of medical adjuvants. The capsule provided by the invention is prepared from the following raw materials by mass: 70 to 90 pars of composite modified starch, 3 to 5 parts of a plasticizer, 10 to 20 parts of vital gluten, 1 to 2 parts of a coagulator and 120 to 200 parts of pure water, wherein the composite modified starch is oxidized cross-linked hydroxypropyl-pregelatinized four-component composite modified starch. According to the method, a raw starch material is prepared by using a four-component composite modification process, so the shortcomings of the performance of conventional raw starch and single or dual modified starch are improved, and retrogradation and ageing of starch are greatly enhanced; and compared with conventional standard gelatin hollow capsules and hydroxypropyl starch hollow capsules, the capsule provided by the invention has obvious better quality.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary materials, in particular to a modified starch vegetable capsule and a preparation method thereof. Background technique [0002] Ordinary capsules can be divided into hard capsules and soft capsules, and hard capsules are also called "hollow capsules". According to the release of contents in specific parts of the human body, it can be divided into enteric-coated capsules and gastric-coated capsules. According to its raw materials, it can be divided into two categories: gelatin capsules and vegetable capsules. At present, the raw material for producing hard capsules in China is mainly gelatin, which is derived from the bones and skin of animals (pigs, cattle, etc.), and its main component is protein. [0003] With the increasingly prominent food safety and animal product safety issues, the shortcomings of gelatin capsules have gradually been discovered: (1) Gelatin molecules are easily c...
