Gelatin is a protein substance that comes from collagen. Collagen is a natural protein found in the tendons, ligaments, and tissues of mammals.

It is made by boiling the connective tissues, bones and skins of animals, usually cows and pigs. Once the boiling is done, the collagen will cool and make a jelly. As a food, gelatin is used to make jellied desserts; used in the preservation of fruit and meat, and to make powdered milk. Gelatin can also be used as glue for matches or for paper money. You can also find it is used as the syrup in medicine. Also known as medicine emulsions.

Gelatin is classed as a liquid when at room temperature but reverts to a solid if below room temperature.
