Almost every country in the EU last week approved the use of Meat Glue in food. Technically called thrombian, or transglutaminase (TG), it is an enzyme that food processors use to hold different kinds of meat together.
Imitation crab meat is one of the more common applications: it's made from surimi, a "fish-based food product" made by pulverizing white fish like pollock or hake into a paste, which is then mixed with meat glue so that the shreds stick together and hold the shape wanted for it by its creator.
Chicken nuggets are also often bound with meat glue, as are meat mixtures meant to mold like sausage but without the casing. Meat glue is also used by high-end chefs like New York restaurant WD-50's Wylie Dufresne, who is famous for his shrimp pasta dish—instead of shrimp with pasta, he just makes the pasta out of shrimp.
