Description

Anti-adhesion soft rubber, soft capsule and preparation method thereof
Technical Field
The invention relates to the technical field of health-care food, in particular to an anti-adhesion soft rubber and soft capsule and a preparation method thereof.
Background
In view of the unique sealing characteristic of the soft capsule, the soft capsule can effectively ensure the stability of the active ingredients of the content, and the soft capsule is widely applied due to the dose controllability and portability of the soft capsule. The soft capsule can be used in medicine, and also can be widely used in health food. In recent years, for the purpose of improving the taking properties, there has been an increasing demand for chewable soft capsules that can be easily taken by anyone without the capsule. The chewable soft capsule has no disintegration process, so that the active ingredients can be quickly absorbed, and the chewable soft capsule is especially suitable for children, the elderly and the groups with dysphagia.
US patent application US20050136104 discloses a chewable soft capsule which maintains a certain softness of the capsule by maintaining a high moisture content, wherein the moisture content in the capsule skin is up to 27%; US6280757 discloses a chewable soft capsule. The soft capsule keeps certain softness by increasing the dosage of the plasticizer, wherein the ratio of the plasticizer to the plasticizer in the capsule skin formula is 100: 100-600.
In order to make the capsule easy to chew, the above patent must have a proper chewing degree, for example, the amount of plasticizer is increased or the moisture content is kept high, so that the capsule can keep a certain softness and is easy to chew, but this can cause easy adhesion between soft capsules and adhesion between the soft capsules and a packaging container, and the temperature resistance is poor, so that the storage stability of the product is affected, and the capsule is not particularly suitable for high-temperature areas.
Therefore, a new solution is needed to solve the above problems.
