How do companies keep a recipe secret?

How does a company such as coke keep their recipe secret without food authorities worrying about the ingredients not being said on the packaging

well the food ingredients are no secret.. any lab can break down a substance to find the ingredients, but its the amounts and how they process it that is a secret..
and most high powered companies, keep half the recipe at one location and half at another location and
only a few higher ups know the actual complete recipe..
