  • The roll meat has a red dye added to it and I've never found it where it didn't have that funny look. We use it for chili or spaghetti sauce and it always works fine.

  • The color of ground beef sometimes has to do with exposure to oxygen after it has been ground.

  • It turns brown when the air has gotten to it. The oxygen makes it change color.

  • My DH used to be a meat cutter at a grocery store. He said that when meat mixes with oxygen it makes it brown.
