I found this but not sure if it's for Albacore specifically:
Chicken of the Sea Ingredients: Solid White Tuna, Hydrolyzed Soy Protein, Vegetable Broth, Salt, Pyrophosphate.
Star Kist Ingredients: Solid White Tuna, Spring Water, Vegetable Broth, and Salt.
Maybe someone in the US can check it though, just to make sure it's not merely BS (from a rival tuna company's website). I would think Chicken of the Sea would have 'spring water' in it too?
