Well, I don't buy meat very often but I went to Walmart today and was going to do a price match on some London Broil. I started putting the meat in bags when I felt a strange prompting to check the label. Guess what? In teeny tiny letters in the corner it said that a 10% solution was added. I don't have any idea what the solution is but I would guess it would include red dye to make the meat look fresh and MSG to make it taste "good".
I was pretty mad as I left and I traveled the whole extra 5 minutes to get to Kents where the special originated. I double checked with their butcher and they definitely do not add a solution to their meats.
