Flavor and fragrant compositions

Claim 2

A process for making compositions having the flavor and fragrance of steam-distilled natural lime oil comprising the steps of refluxing a mixture of citral, an acid selected from the group consisting of mineral acids and organic acids and water for 0.5 to 5 hours at 25-100° C., the ratio of citral to acid being from about 1:1 to 20:1 and said mixture having a pH of less than 5.5, steam distilling the refluxed material, recovering the distillate, and adding an effective amount of the distillate obtained from the distilling of the refluxed material to a carrier material in which the flavor or fragrance of the lime oil is desired.

Claim 3

A process in accordance with claim 1 wherein said distillate contains about 60% by weight of terpene hydrocarbons and about 5% of 1-methyl-1,3-cyclohexadiene.

Claim 4

A process in accordance with claim 1 wherein said distillate is present in an amount of 0.1% to 10.0% by weight of the total composition.

Claim 5

A process in accordance with claim 1 wherein said carrier is selected from the group consisting of water, ethanol, glycerol, propylene glycol, and mixtures thereof.

Claim 6

A process in accordance with claim 1 wherein said acid is selected from the group consisting of hydrochloric, phosphoric, sulfuric, benzoic, oxalic, tartaric, malic, malonic and citric acid.

Claim 7

A composition having the flavor and fragrance of steam-distilled natural lime oil, said composition having a carrier material and being characterized by the fact that said flavor and fragrance of steam-distilled natural lime oil has been imparted thereto by the inclusion in said composition of an effective amount of a material which has been formed by the steps of refluxing for 0.5 to 5 hours and at a temperature between about 25° and 100° C. a mixture of citral, an acid selected from the group consisting of mineral acids and organic acids, and water, the ratio of citral to acid being from about 1:1 to 20:1 and said mixture having a pH of less than 5.5, and steam distilling the refluxed material and recovering the distillate.

Claim 8

A composition having the flavor and fragrance of steam-distilled natural lime oil, said composition having a carrier material and being characterized by the fact that said flavor and fragrance of steam-distilled natural lime oil has been imparted thereto by the inclusion in said composition of an effective amount of a material which has been formed by the steps of refluxing for 0.5 to 5 hours and at a temperature between about 25° and 100° C. a mixture of citral, an acid selected from the group consisting of mineral acids and organic acids, and water, the ratio of citral to acid being from about 1:1 to 20:1 and said mixture having a pH of less than 5.5, and steam distilling the refluxed material and recovering the distillate.

Claim 9

A composition in accordance with claim 6 wherein said carrier material is selected from the group consisting of water, alcohol, mineral oil, lanolin, almond oil, sterols, glycerine, sorbitol, propylene glycol, diethyl phthalate, monochlorodifluoromethane, dichlorotetrafluoroethane, and trichloromonofluoromethane, and the flavor and fragrance imparting material is present in an amount between about 0.05 and 10% by weight of said composition.
