　　What is the material of the capsule shell? The capsule shell is made of food-grade gelatin after careful processing and some auxiliary materials. Capsule shells are used to contain solid powders and granules because of their good absorbability and fast and reliable dissolution. Because of this characteristic of the capsule shell, it is mainly used in the pharmaceutical industry. There are also special hollow medical capsules on Taobao, which are used to hold some difficult-to-drink powder medicines or powder medicines, which solves the problem that some people's good medicines taste bitter.

　　There are two types of capsules: soft capsules and hard capsules. Soft capsules refer to drugs that are manufactured together with a capsule shell. Hard capsules refer to hollow capsules, which are specially used to give medicines orally to some people. Hard capsules are divided into empty gelatin capsules and vegetable capsules, mainly empty gelatin capsules.

　　Edible gelatin is widely used in food, and we can find Mingjiao in some common foods. Such as jelly, vat, candy, etc. Edible gelatin itself is a water-soluble protein extracted from collagen in connective tissue.

　　There are many kinds of edible gelatin, mainly obtained from the skin and bones of animals. Edible gelatin, which is specially used to make capsule shells, is a pharmaceutical-grade specification.

　　The production process of an empty capsule is very simple: pour edible gelatin into a stainless steel mold, and form a layer of gelatin film on the mold steel. After air-drying, the gelatin film dries and hardens, forming the capsule shell, which is then removed from the mold.
