Liquid smoke has nothing to do with chemistry.
It is a naturally processed and refined smoke condensate which is won by mouldering wood combined with a water-
The raw condensate is then exempted from unwanted components, first of all from polycyclic aromatic hydrocarbon (PAH), tar and other particles.
However all flavouring and browning components remain.
It can be used in any appliances for smoking and/or smoke-
Liquid smoke contains neither carbon monoxide nor nitrogen oxides.
The content of carcinogenic PAH (mainly benzopyrene) is lower than
No fire hazard, because there is no smouldering wood involved.
No explosion hazard, because the process generates neither carbon monoxide nor other flammable gases.
No chemical hazards from carbon monoxides or carcinogenic dust from beech wood.
Lower chemical risk from PAH.
Significantly reduced contamination leads to minimal cleaning effort, especially when utilizing water soluble liquid smoke.
The pollution of exhaust and effluent is also considerably reduced.
