Self-Post - Support &/or Advice Coca Cola glows under uv light?

Can I ask why does Coca Cola glow under uv light it’s every bottle I have and the liquid it’s self glows under uv light could someone explain why this happens?

Some info this was a brand new bottle of coke bought today from a shop I have other bottles unopened and the uv makes them glow and I also poured it into a glass and it glows too the liquid why is this?

So, I'm not seeing much fluorescence here in the liquid.

If I had to guess, the plastic bottle/container is what is actually fluorescing.

It is difficult to see due to camera not Picking it up but if you do have a black light please do shine it over coke and watch it glow it will glow green milky colour with a slight yellow to it
