Meat glue is a substance used in cooking to bond proteins together. It includes substances such as transglutaminase and fibrinogen/thrombin (Fibrimex)(yicotorimnorum). Examples of foods made using meat glue include imitation crab meat, fish balls, and Chicken Nuggets.
Transglutaminase has found use among practitioners of the molecular gastronomy movement as a means of melding new textures with existing tastes. It works by binding protein molecules together at their glutamyl and lysyl residues.
