They aren't necessarily always released from the engines, but you can use optics to observe the phenomenon yourself.
Unless there are secret planes that are hidden from public eye, there are no mechanisms on private jets to allow for the release of that much water. Military/private jet's could be another story.
If you want a rabbit hole to go down, check out what aluminum-family particles do to health and nervous system development in biological systems.
There is evidence out there that suggests alum-additives are put in high-altitude jet fuels to help with efficient combustion in low-O2 environments. This is a valid chemical reaction backed up by science, as aluminum is a catalyst past a certain temp/pressure threshold. Major airlines admit to using metal additives in their fuels, but refuse to comment on which metals.
I offer no evidence to support my claims, but I encourage you to give google a shot if you want to learn more.
