Description
~` 106ZZ69 Thi8 invention relates to flavor compo~itions and more par-ticularly to flavor compositions containing an alkyl-2,3-dihydro-3(1'hydroxyalkylidene)-2-oxo-5-alkyl-furan-4-carboxylate.
. . - .
It is well known that synthetic flavor enhancers such as Maltol, Ethyl Maltol, and 4-hydroxy-2,5-dimethyl-3(2H)-furanone are useful as flavor enhancers. However, ~uch flavor enhancers are very expensive and increase the cost of pxoducts in which they are used.

It is well known that synthetic flavor enhancers such as Maltol, Ethyl Maltol, and 4-hydroxy-2,5-dimethyl-3(2H)-furanone are useful as flavor enhancers. However, ~uch flavor enhancers are very expensive and increase the cost of pxoducts in which they are used.
In accordance with one feature of this invention, an alkyl-
2,3-dihydro-3(1'hydroxyalkylidene)-2-oxo-5-alkyl-~uran-4-carboxy-late is added to flavor components to impart a significantly en~
hanced flavor to a wide variety of flavor components. For exam-ple, butterscotch flavors are materially improved in smoothness.
Strawberry flavors are given a striking freshness. Banan~ flavors are rounded out to give the flavor of a ripe banana. When added to smoking tobacco or synthetic tobacco, the resulting product is increased in ~weetness, the taste of the smoke i~ softened and the -.
flow of saliva is increased, which lessens dryness of the mouth during smoking. When added to cough syrup containing theophyl-line, the flavor enhancer of this invention covers up the bitter taste. This flavor enhancer can also be used to replace part of the sugar content of a wide variety of sweetened beverages and foods, producing excellent flavor at lower cost.
Alkyl-2,3-dihydro-3(1'-hydroxyalkylidene)-2-oxo-5-alkyl-furan-4-carboxylates employed in the flavor compositions of this invention have the formula:
H
Rl O
., 0/
:.
in which Rl is a straight or branched chain alkyl having les~
than 6 carbon atoms, and R2 is a straight or branched chain alkyl having less than 7 carbon atoms, cyclopentyl or cyclo-hexyl.
Examples of Rl are methyl, ethyl, propyl, isopropyl, butyl, -isobutyl, amyl and isoamyl.
Examples of R2 are methyl, ethyl, propyl, isopropyl, butyl, isobutyl, amyl, isoamyl, hexyl or isohexyl.
Rl and R2 may be the same or different.
The alkyl-2,3-dihydro-3(1'hydroxyalkylidene)-2-oxo-5~alkyl-furan-4-carboxylates may be prepared by the general methods of Knorr, Ber. 1889, 22, 158.
The flavor compositions of this invention comprise at least 0.0025% by w~ight of one or more alkyl-2,3-dihydro-3(1'hydroxy-alkylidene)-2-oxo-5-alkyl-furan-4-carboxylates. The amount of alkyl-2,3-dihydro-3(1'hydroxyalkylidene)-2-oxo-5-alkyl-furan-4-carboxylate may vary within wide ranges such as 0.0001% to 30%
lO~;Z269 by weight. More advantageously the range may be between 0.001%
and 20% by weight of the flavor composition and preferably be-tween 0.0025% and 5% by weight of the flavor composition.
Examples of flavor components of the flavor compositions of this invention are flavor mixtures E~ se such as pineapple, butterscotch, banana, and strawberry; food~tuffs such as meats, protein sources, fruits, cereals and other comestibles; beverages such as soft drinks, wines, alcoholic drinks, carbonated beve-rages; smoking tobacco; liquid medicaments such as cough syrups;
and sugar substitutes in a wide range of edible or drinkable products.
In accordance with another feature of this invention, cer-tain alkyl-2,3-dihydro-3(1'-hydroxyalkylidene)-2-oxo-5-alkyl-furan-4-carboxylates are new and novel. Such new and novel car-boxylates significantly enhance the flavor components of the com-positions of this invention. The new and novel carboxylates have the following formula:

To produee a flavored tobaceo whieh also eontains synthetie tobaeeo, the procedure for the production of tobacco flavor com-position heretofore described in this Example is repeated except that instead of employing -moking tobacco only, synthetic tobacco such as cellulose fibers, for example, the cellulose fibers sold by the Celanese Chemical Company under the trademark "CYTREL" or ! the eellulose fibers sold by Imperial Chemical Corporation under -the trademark "POLYSTREP", is blended with the flavored tobaceo in a ratio of approximately 1 to 1 by weight.
In a third proeedure, a 1% etha~ol solution of ethyl-2,3- -dihydro-3~ hydroxyethylidene)-2-oxo-5-methyl-furan-4-carboxylate _ g _ . ' ', .: ~.' ' ' 106226g is sprayed on synthetic tobacco, such as cellulose fibers, at the rate of 4 ounces of solution to 100 pounds of synthetie tobacco. After the alcohol is allowed to evaporate, a tobaeeo flavor synthetic composition results.
Any one of the above tobacco flavor eompositions may be used in cigarettes, producing a striking improvement in flavor.
` Experiments were conducted with panatela cigars using ethyl-2,3-dihydro-3(1'-hydroxyisopentylidene)-2-oxo-5-isobutyl-furan-4-carboxylate as the flavor enhaneer in 95% ethanol at the rate of 1.5 ounces of enhaneer to 100 pounds of panatela eigars.
The aroma and flavor of the smoke were signifieantly improved.

EXAMPLE VIII
-~ CARBONATED SOFT DRINKS
., _ A fruit flavor earbonated soft drink is produeed by dissol-ving one ounee by weight of one of the flavor eompositions sueh 2` as deseribed in Examples I or II in one gallon of sugar syrup.
One ounee of the resulting mixture is added to about five ounees of earbonated water to produee six ounees of earbonated beverage.
`~ ' ' The flavor eompo~ition eontaining 2.5% by weight of ethyl-2,
3-dihydro-3(1'-hydroxyethylidene)-2-oxo-5-methyl-furan-4-earboxylate results in a level of 32 parts per million of ethyl-2,3-dihydro-3(1'-hydroxyethylidene)-2-oxo-5-methyl-furan-4-earboxylate flavor enhaneer in the total earbonated drink produeed.
