Smoky flavourings can work as flavour enhancers in the right dosage without really adding any smoky flavour. Added in a higher dosage they can add smoky, charred, BBQ, smoked meat, woody or umami type of notes. They are very popular in snack flavourings where e.g. a bacon flavour or BBQ flavour is needed. Meat type flavours have become very popular in the snack industry, and that make smoky flavourings as valuable building stones.
