Someone just used gas chromatography to develop a seemingly passable knock off of the unpatented Coca Cola formula and posted it online. https://youtu.be/TDkH3EbWTYc

I firmly believe that such thing is already know by companies...

In the niche perfumes hobby, you have small brands doing that or people paying for gcms analysis on perfumes, i guess that companies have already done that on coke for decades
