no, faggal sugar. so when I do make marinades, I make them myself, using worcestershire sauce, olive oil, lemon juice (very little) and soya sauce <- wenner vir 'n steak
nothing beats a it of Coke in teh marinade, the acids break down the fibers in the muscle making the Steak super tender.
the other day we did not have coke in teh house, so we soaked the steak in a bit of balsamic vinegar for about 45 min. (get the process started)
then rinsed it off propperly. and then put it in a spiced gold, worcestershire, soya and olive oil marinade. let that sit for another 45 min.
the lemon juice does the same thing, but honestly the acids in coke (regular not coke zero) works the best.
