Abstract
A method of producing a browning liquid product by pyrolyzing sugars and starches. The browning liquid imparts a brown, smoked color to a cooked foodstuff without imparting an undesirable strong smoked flavor to the foodstuff.
Claims31
A method of producing a browning liquid product for application to foodstuffs comprising the steps of:
- (a) pyrolyzing a feedstock selected from the group consisting of a sugar, a starch and mixtures thereof to produce a vaporous pyrolysis product and a pyrolytic residue, said vaporous pyrolysis product comprising condensable vapors and noncondensable vapors;
- (b) separating the vaporous pyrolysis product from the pyrolytic residue and unpyrolyzed feedstock;
- (c) condensing the condensable vapors in the vaporous pyrolysis product to produce a water-soluble pyrolysis liquid;
- (d) contacting the water-soluble pyrolysis liquid with a water-insoluble organic extraction solvent to extract flavoring materials from the water-soluble pyrolysis liquid into the water-insoluble organic extraction solvent;
- and
- (e) separating the water-insoluble organic extraction 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.
A high browning, flavorless aqueous composition derived from vapor of a pyrolyzed material selected from the group consisting of a sugar, a starch and mixtures thereof, wherein the material is pyrolyzed at about 400.degree. C. to about 1000.degree. C. and the composition has a soluble organic content of less than 50.degree. Brix, a browning index greater than about 30, and ratio of titratable acidity to browning index of less than about 0.06.
A high browning, flavorless aqueous composition derived from vapor of a pyrolyzed material selected from the group consisting of a sugar, a starch and mixtures thereof, wherein the material is pyrolyzed at about 400.degree. C. to about 1000.degree. C. and the composition has a casing browning density of greater than 0.03.
A method of producing a browning liquid product comprising the steps of:
- (a) pyrolyzing a feedstock selected from the group consisting of a sugar, a starch and mixtures thereof to produce a vaporous pyrolysis product and a pyrolytic residue, said vaporous pyrolysis product comprising condensable vapors and noncondensable vapors;
- (b) separating the vaporous pyrolysis product from the pyrolytic residue and unpyrolyzed feedstock;
- (c) condensing the condensable vapors in the vaporous pyrolysis product to produce a water-soluble pyrolysis liquid;
- and
- (d) contacting the water-soluble pyrolysis liquid with a member of the group consisting of an cationic exchange resin, a nonionic exchange resin and mixtures thereof to remove flavoring materials and thereby produce a browning liquid product which has no detectable smoke flavoring ability by taste.
