What's Hidden in Your Simple Tomato Paste?

We generally by the same brand of concentrated tomato paste (the 28% variety) all the time. When I first discovered it, it just had tomatoes and nothing else. But every once in a while there an unpleasant surprise.

I've been checking various brands, and they all have lots of added junk. This new one has 8% garbage (sugars and who knows what else) in it. And the warning that it "May contain celery, mustard, sesame, eggs, soy and sulphite." really ruins my appetite.
