what is porcine gelatin

Porcine gelatin is a protein substance derived from boiling the skin or connective tissue of pigs. It is widely used in the food and pharmaceutical industries. Pork skin gelatin, for example, is a protein product produced by partial hydrolysis of collagen-rich pork skins. Gelatin is also used in vaccines as a stabilizer and to help preserve the vaccine. Porcine gelatin is commonly used in the production of gelatin, but there are also other sources such as bovine and fish. It is important to identify and authenticate the raw materials used in gelatin production, particularly porcine, since it is prohibited for Muslim consumption. There are different methods to identify bovine and porcine gelatins, such as enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) . For example, Venien and Levieux developed an ELISA method to identify bovine and porcine gelatins, which was able to identify the reactivity and sensitivity differences between bovine and porcine gelatins.
