Abstract
The invention relates to a process for producing a liquid product for coloring and flavoring a foodstuff by pyrolyzing sugars and starches. The liquid product is useful for imparting a brown smoked color to a foodstuff without adding undesired strong smoked flavors to the foodstuff.
Claims25
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.
A high browning flavorless aqueous composition derived from vapor of a pyrolyzed material selected from the group consisting of sugar, starch, and mixtures thereof, wherein said composition has a soluble organic content of less than about 50.degree. Brix, a browning index greater than about 30 and ratio of a 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 sugar, starch, and mixtures thereof, wherein said composition has a casing browning density of greater than 0.03.
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;
- and
- 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 which has no detectable smoke flavoring ability by taste.
