As the answers seem far from the correct one, I want to bring your attention to the fact that I hinted it being a PART of a consumable object, the part itself should not be consumed and is always discarded, unless the consumer is a weirdo 
Also, remember that the largest distributor is Mexico.
Additional hint, the part in question is round and not only is Mexico the largest distributor of this item which contains the object in the picture, it is considered Mexico's #1 food export item. But item in the picture is not the item, it is part of the item, remember the previous clues. With additional hint, the amount of guesses is yet again reset.
