Abstract
A tar-depleted liquid smoke having total water miscibility, and related method for making same. The tar-depleted liquid smoke may be made from commercially existing liquid smoke products, for instance, by treating such a commercial product with a column filtration process using activated carbon particles packed in the column. The resultant tar-depleted liquid smoke typically will have a phenols reduction of about 10% to about 90% compared to the commercial starting product of liquid smoke. In an alternative embodiment, the tar-depleted liquid smoke made from carbon contact is then vacuum concentrated so that it has a phenols content greater than that of the commercial starting product of liquid smoke, but the concentrate will still be totally water miscible.
