Why haven't we been able to analyze samples of different foods to find out exactly what the ingredients are and the percent of each ingredient in the food? You know, to unlock the mysteries of Coca-Cola, Big Mac sauce, etc.

Or does this technology already exist? If so, how can these "top secret" recipes still remain secret?

We can do this. We can tell you exactly what chemicals are in any particular food. The problem is, if you're attempting to replicate a "secret recipe" is that most of these chemicals will be complicated organic molecules, so we can't exactly reconstruct from scratch by adding chemicals to a vat because it'd be prohibitively time consuming and expensive. 

Knowing what's in something doesn't tell us the method of creation.
