Abstract
Abstract Processes for obtaining food flavoring materials and for preparing foodstuffs comprising heating at least one conjugated oxygen-containing carbonyl compound such as a hydroxyfuranone, a hydroxylactone, or a hydroxypyrone in the presence of hydrogen sulfide to obtain hearty flavoring compositions, particularly compositions having meat and cheese flavors; together with the compositions so obtained.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
184 words
A process comprising heating in solution at least one cyclic carbonyl compound having the formula ##STR11## wherein the dashed line is a single bond or a carbon-carbon double bond; Y is --O--, --CR 3 R 4 -- or =CR 3 --; X is --O-- or --CR 2 R 5 -- when the dashed line is a single bond and Y is --CR 3 R 4 --; X is --CR 2 R 5 -- when the dashed line is a single bond and Y is --O--; X is =CR 2 --O-- when the dashed line is a double bond, and Y is =CR 3 -- when the dashed line is a double bond; R 1 , R 2 , R 3 , R 4 , and R 5 are the same or different and are lower alkyl or hydrogen; with hydrogen sulfide in the molar ratio of sulfide to carbonyl compound of from about 0.05:1 to about 3:1 under a pressure of from about two to ten atmospheres to produce a hearty flavoring material, said solution being substantially free of esters of hydroxy polybasic acids.
Claim 2
Dependent Claim
