Gelatin hollow capsule components

Most capsules are made of gelatin.  Gelatin is widely used in many foods, such as puddings, sweets, candied fruits, chewing candies, sugar coating, food filling heads and dip.  In food, gelatin can help food solidify, thicken, stabilize and ventilate. It is a very popular food ingredient rich in nutrition and low in fat.  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 types of gelatin.  Capsules are made of pharmaceutical grade gelatin, which meets the strict requirements for pharmaceutical products.  The procedure for making capsules is to first form a gelatin film on a stainless steel mold.  The gelatin film then dries and hardens to form capsules, which are then removed from the mold.  Generally, there are two kinds of molds, one for making capsule body and the other for making capsule cap with larger diameter.
