1. A process for producing a pyrolysis product of sugars, starches or mixtures thereof comprising:

  • pyrolyzing a member of the group consisting of sugar, starch and mixtures thereof to produce a vaporous pyrolysis product;

    condensing the vaporous pyrolysis product to produce a water-soluble pyrolysis liquid;

    contacting the water-soluble pyrolysis liquid with an organic solvent which is essentially insoluble in water to extract flavoring materials from the water-soluble pyrolysis liquid into the organic solvent; and

    separating the organic solvent from the so-extracted water-soluble pyrolysis liquid to yield the so-extracted water-soluble pyrolysis liquid as a browning liquid product which has substantially no detectable smoke flavoring ability by taste.
