Abstract
The flavoring compositions and flavored comestibles of this invention include alkyl 2,3-dihydro-3(1'-hydroxyalkylidene)-2-oxo-5-alkylfuran-4-carboxylates in amounts capable of significantly enhancing the flavor of the flavoring compositions or flavored comestibles. For example, butterscotch flavors are materially improved in smoothness and certain fruit flavors are given greater richness and ripeness when the carboxylates of this invention are incorporated therein. Similarly, fruit flavored carbonated soft drinks which include the carboxylates possess enhanced flavors.
Claims13
A flavoring composition having enhanced flavor character comprising an alkyl 2,3-dihydro-3(1'-hydroxyalkylidene)-2-oxo-5-alkylfuran-4-carboxylate having the structure:
- ##STR2## wherein each of R.sub.1 and R.sub.2 is methyl or ethyl and is the same or different and conventional flavoring ingredients, said carboxylate being present in an amount 0.01% to 30% by weight which is effective in enhancing the flavor of said flavoring ingredients, said flavoring ingredients comprising pineapple, butterscotch, banana and strawberry flavoring compositions.
