Transglutaminase (TG), aka Meat Glue, is a natural enzyme that has the ability to glue protein-containing foods together. When raw meats are bound with TG, they typically have the strength and appearance of whole uncut muscles. Activa RM is the most popular TG formulation used by chefs. In addition to transglutaminase and maltodextrin, it contains a water soluble milk protein called sodium caseinate. This helper protein compensates for any protein deficiencies by sticking to the surface of the food and bonding with the TG. This makes Activa RM ideal for difficult foods, including cooked meats. And there is no downside to including sodium caseinate, even if the application doesnt require the extra bonding power that it provides. So Activa RM is your best bet for most meat glue recipes. The main components : sodium caseinate, maltodextrin, and transglutaminase.
