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

[Mintee]

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..
