Most capsules are made of gelatin. Gelatin is widely used in many foods, such as pudding, candy, candied fruit, chewable tablets, sugar coating, food stuffing and dip. In food, gelatin can help food to solidify, thicken, stabilize and ventilate. It is a very popular food ingredient with rich nutrition and low fat content. Gelatin itself is a water-soluble protein extracted from collagen, which is the main natural protein component in connective tissue. Gelatin is obtained from the skin and bones of animals through a controlled extraction process. There are many kinds of gelatin. The capsule adopts medical grade gelatin, which meets the strict requirements for pharmaceutical products. The procedure of making capsules is to form a gelatin film on a stainless steel mold.
