The braised beef I bought quickly has a piece of glue on each piece. It's true, beef glue. Carrageenan is used. Carrageenan is used to make artificial beef. Carrageenan is a kind of food additive, which can be eaten in moderation. In addition to water retention, it also has a special function, that is, it can bond minced meat together. In addition to carrageenan, there is another additive called TG enzyme, whose professional name is "Glutamine Transaminase", which can catalyze the cross-linking between protein molecules and also has the function of recombining minced meat.
