Problems solved by technology

[0003] Due to its special molecular structure, animal-derived gelatin has many disadvantages in practical application: (1) The water content is too high, and the hygroscopic drug filled is easy to absorb the water in the soft capsule shell, resulting in drug instability and easy rupture of the capsule shell (2) High degree of cross-linking, prone to amino acid cross-linking reaction, resulting in disintegration or reduced dissolution of soft capsules; (3) Gelatin easily reacts with aldehyde-containing pharmac

Embodiment 1

[0031] Embodiment 1: a kind of vegetable capsule shell of soft capsule, it comprises the raw material of following weight ratio:

[0032] Agar 3Kg, Alginate 4Kg, κ-Carrageenan 10Kg, Sorbitol 25Kg, Glycerin 15Kg, CaCl 2 0.02Kg, water 43Kg.

[0033] Vegetable capsule shells can be prepared by the existing soft capsule production method. The compressed capsules are sent to a drying room for drying, the drying temperature is set at 40° C., the relative air humidity is controlled at 30%, and the drying time is about 3 hours.

[0034] Evaluate the rubber elasticity, strength and bonding temperature of the product of Example 1, and measure the appearance properties, moisture content, disintegration time limit and other indicators for the soft capsule samples produced in a small trial.

[0035] The results are shown in Table 1:

[0036] The capsule shell property of table 1 embodiment 1

[0037]

Embodiment 2

[0038] Embodiment 2: a kind of vegetable capsule shell of soft capsule, it comprises the raw material of following weight ratio:

Abstract

The invention relates to formulae and properties of seaweed gel plant soft capsule shells. The formula of the seaweed gel plant soft capsule shell comprises 10-30 parts by weight of a seaweed gel, 30-50 parts by weight of a plasticizer, 0.001-0.1 part by weight of a coagulant aid and the balance of water, wherein the water content accounts for 10-20% of the total weight of the capsule shell. The seaweed gel plant soft capsule shell provided by the invention has the characteristics of being colorless and transparent, high in elasticity, high in strength, low in bonding temperature and the like.

Description

technical field [0001] The invention relates to the technical field of soft capsules, in particular to the formula and properties of vegetable soft capsule shells with alginate as the main raw material. Background technique [0002] Soft capsule refers to a dosage form made by sealing a certain amount of oily liquid medicine or semi-solid contents such as suspensions and emulsions in spherical or oval soft capsules. It has been widely used in health care products and Preparation of medicines. Compared with other solid dosage forms, soft capsules have the advantages of high bioavailability, good sealing performance, beautiful appearance, and suitable for multiple purposes. In recent years, due to its unique properties and efficacy, soft capsules have been paid more and more attention by the medical and health circles, and their applications have become more and more extensive. At present, the medicines and health foods of soft capsule preparations at home and abroad, the va...
