The ingredients for mozzarella are: buffalo milk, salt and rennet (and a bit of leftover whey for the bacteria). I’m sure there is far more in a packet of “cheese strings” than that
rennet = enzymes and the original list left out cultures, but there are undoubtedly cultures in their cheese, so the only difference in the lists is presentation.
