What information does the ingredients list give on a food label?

Food manufacturers are required to list all ingredients in the food on the label. On a product label, the ingredients are listed in order of predominance, with the ingredients used in the greatest amount first, followed in descending order by those in smaller amounts. The label must list the names of any FDA-certified color additives (e.g., FD&C Blue No. 1 or the abbreviated name, Blue 1). But some ingredients can be listed collectively as "flavors," "spices," "artificial flavoring," or in the case of color additives exempt from certification, "artificial colors", without naming each one. Declaration of an allergenic ingredient in a collective or single color, flavor, or spice could be accomplished by simply naming the allergenic ingredient in the ingredient list.
