Crackers, pretzels and popcorn without the listed preservatives

41 of the 49 crackers, pretzels and popcorn foods on the list pass this check. A short, fixed list: BHA, BHT, TBHQ, potassium bromate, brominated vegetable oil, propylparaben and azodicarbonamide. Other preservatives, such as citric acid or sorbates, are not counted.

They may still fail one of the other four checks; the strip on each card shows which. The 8 that fail it are on the full crackers, pretzels and popcorn page.
