Can juice get "burned"? (Dark juice after mixing)

[moleculo]

This may be a silly question, just bear with me please.

Lately, I have been adding the last few drops of juice left in my tank to a designated "jungle juice" bottle. I planned on using the "jungle juice" bottle of mixed juice when I was running low on other juice, or just if I felt like it.

Anyway, after mixing two kinds of juice (from same producer), the juice turned very dark, a very dark brown, while originally the two different juices were very light colored. Can juices react with one another and just produce a different color? I've mixed juice before but never seen such a drastic color change.

Then I wondered if juice can literally be burned if used in a tank with a burned-out/dying atomizer/coil. Anyone aware of this ?

Just curious, any feedback is appreciated.

I've had that happen once or twice--tried to stretch the use of a coil, and having my liquid taste burnt. And, yes, juices can change colors a bit if you mix them together.

That little bit of juice left in the tank has been heated up several times which will turn it darker, Nicotine by trait will get darker the more light and air it is exposed to.

One of the juices that I use will turn from clear to dark amber and develop a bitter taste unless I wash out the tank and coil regularly. I think this is a consequence of the juice burning onto the coil and then slowly being dissolved when the tank is not in use.

I have never seen much colour change in the liquid I have stored, but I wouldn t pour any juice out of the tank back into the bottle anyway
