United States Patent 3,353,961 STABILIZED FLAVORING CONCENTRATES Clarence K. Simon, Forest Hills, N.Y., assignor to Dominion Products, Inc., Long Island City, N.Y., a corporation of New York No Drawing. Filed Dec. 30, 1963, Ser. No. 334,624 17 Claims. (Cl. 99-78) ABSTRACT OF THE DISCLOSURE The present disclosure sets forth the use of glyceryl abietate and particularly triglyceryl abietate combined with orange oil terpene fractions to obtain a uniform anhydrous combination readily emulsified with gum arabic and combined with Water and sugar syrup to form an orange drink.

The present invention relates to a stabilized flavoring concentrate and it particularly relates to a stabilized flavoring concentrate of an essential oil.

Although not limited thereto and having ready applicability to various citrus oils, the present invention will be particularly described in its application to orange oil fractions and particularly terpene fractions thereof.

In making the orange oil emulsions or drinks it is usually necessary to include therein various types of brominated oilssuch as brominated sesame seed oil to prevent separation and to give the oil the same specific gravity as the aqueous medium in which it is placed or suspended.

It has been particularly found that it is necessary that a brominated oil be utilized which has a higher specific gravity than one, so that the resultant combination will have a specific gravity of one plus and will not readily separate or form a ring or scum, when included in aqueous mixtures. I

It is amongthe objects of the present invention to provide a flavoring concentrate of the character described which may be converted into an emulsion for addition to aqueous liquids and readily stirred therein to form variring or.separate. therefrom.

Still further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration and explanation only and not by way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope and spirit of the present invention.

In accomplishing the above objects it has been found that a glyceryl abietate and particularly a triglyceryl abletate may be most conviently combined with essential oil terpene fractions and particularly with orange oil terpene fractions to achieve a uniform and anhydrous composition which may be readily emulsified with gum arabic and combined with water and particularly with a sugar solution to form a flavored drink and particularly an orange drink.

It has been found most satisfactory to use the terpenes derived from orange or other essential oils which have a specific gravity of between 0.8 to 0.9 and desirably about 0.84.

These terpenes are derived by fractional separation or distillation of the orange or other essential oils and after they have been combined with the glyceryl abietate they gum arabic may also be included.

may then 'be combined with a powdered gum such as gum arabic.

The present invention is particularly directed to the concentrate of orange terpenes and glyceryl abietate. Generally these orange terpenes are derived by distillation of orange oil and constitute about to of the orange oil with the residue being terpeneless concentrated orange oil. a

This concentrate which may contain to 200 parts by weight of the orange terpene and 250 to 300 parts by weight of the glyce-ryl abietate or ester gum then may be homogenized with water and gum arabic to form a ringless, cloudy neutral emulsion using about 50 to 75 parts by weight of the concentrate, 100-200 parts by weight of the gum arabic and about 200-400 parts of water.

This will produce an emulsion which may be added in the amount of about /2 to 2 ozs. to a gallon of sugar syrup desirably about 2540 Baum.

This sugar syrup then may be combined with 3 to 6 times its weight of water to form the final drink.

The flavoring is desirably added to the concentrate either in the form of an artificial imitation oil in the amount of /2 to 2 parts to each 300-500 parts of the combination of orange terpenes and ester gum.

Desirably, the concentrate also should have added thereto about 1 to 3% of an anti-oxidant. H

The cloudy neutral emulsion which is produced from the concentrate by homogenization with water and gum arabic should contain benzoate of soda as a preservative agent.

The present invention is particularly directed to the initial concentrateflavored or unflavored-and which is devoid of brominated oil and which nevertheless will produce an oily flavoring material which will not separate.

Example I Ingredient Range Preferred Orange terpenes 2, 000 to 3, 500 2, 600 Glyceryl abietate 3, 500 to 6, 000 4, 540 Antioeidaut 1 to 8 5 This composition is desirably prepared by dissolving the orange terpenes in a 'water jacketed kettle, followed by stirring in the abietate until it is dissolved. "Stirring is continued for about 15 minutes or more and then the antioxidant may be added. If desired, 15 to 25 parts of This combination then maybe homogenized with water and gum arabic to produce an emulsion.

Thi emulsion may be added in the amount of A to 2 ozs. to a gallon of 32 Baum sugar syrup to produce a syrup for combination with water to form a drink. The concentrate may be flavored in accordance with the particular fiavor desired, whether an orange drink, a lemon drink, a lime drink or a pineapple drink; as well as other flavors. i

The final drink may be preserved by adding M to 1% of benzoate of soda to the emulsion.

Example II ized and .3 to .6 part of an antioxidant such as butylated 'hydroxy anisol, all parts by weight. If desired, to 3 parts by'weight' of g'u'marabic' may also be added.

Desirably about 150 lbs. of the orange terpenes are placed in a water jacketed kettle with or without heating and the finely ground or flaked ester gum is stirred in until dissolved. Then the antioxidant is added. Finally gum arabic may be stirred in until a complete solution is achieved, if it is to be added.

In the preferred composition 150 parts by weight of the orange terpenes are used for each 225 to 300 parts of the ester gum. If desired, 1 to 2 parts of gum arabic may be added. A small amount of flavoring may then be added in the amount of A2 to 2 parts by weight.

To produce a satisfactory ringless, cloudy, neutral emulsion for addition to a 25 to 35 Baum sugar syrup, this concentrate may then be combined with about 30-40 parts of powdered gum arabic for each 50-70 parts of the concentrate followed by the addition of about 200- 250 parts of water.

Finally, about -10 parts by weight of a 25% solution of benzoate of soda is added to give a uniform liquid which may be passed through a homogenizer from two to five times, and desirably three times, to give a uniform emulsion.

This emulsion may be added in the amount of /2 oz. to 3 025. to each gallon of sugar syrup to form a base syrup for addition to 4 to 5 gals. of water to form the final drink.

Example III The following proportions and steps may be used to give a ringless, cloudy neutral emulsion.

This composition is passed through a homogenizer three times and color and flavor may be added to the emulsion as formed if it has not been previously added to the concentrate. Gum arabic may be put in at one time but it is preferred to put it in in stages.

Example IV As an alternative method of preparing an emulsion using the same steps as above the following formulation may be'employed.

Ingredient Range Preferred (a) Concentrate of Examples I or II 80 to 100 lbs 90 lbs. (b) Powdered gum arabic with stirring 45 to 65 lbs 55 lbs.

to dissolve. (0) Water with stirring 30 to 50 gal. 40 gel. ((1) Powdered gum arabic with stirring 100 to 150 lbs 137 lbs. (e) Water with stirring to 20 gal gal. (f) Powdered gum arabic with stirring- 50 to 75 lbs 64 lbs. (g)t Be nzoate of soda 25% solution with 1 to 2 gal 1% gal.

s nring.

This is desirably run through a homogenizer 2 to 4 times. Color and flavor may be added to the concentrate or to the emulsion before homogenization.

Example V Although desirably the neutral emulsion is combined in the amount of /2 to 3 oz. per gal. of a 32 B. sugar syrup which can be then mixed with 4 to 5 times its weight of water to form the final drink, the final drink may also be made directly from the concentrate in the following manner.

This drink may be flavored by adding concentrated orange, lime or pineapple essence and also color to the final drink or to the concentrate.

The drink may be preserved by adding /1()% of benzoate of soda or .05% methyl or propyl parahydroxybenzoate.

Desirably in the above combinations there should be about twice as much gum arabic as orange terpenes and the ester gum of glyceryl abietate should be about 2 to 4 times the weight of the orange terpenes.

The important feature of the present invention resides in the fact that brominated oil may bealtogether eliminated with the production of a ringless drink.

If desired, orange juice may be added to the final syrup or emulsion in the amount of 5 to 20% and the final emulsion, syrup and drink will be non-scumming and non-ringing, and will be stable in glass, will not tend to oxidize, and will have a shelf life of 40 to days and up to 6 months without losing or deteriorating in its flavor.

Furthermore, the flavor will be retained without change from 0 C. or 32 F. up to 75 C. and 150 F.

The present combination is particularly suitable for addition to carbonated beverages.

It is particularly valuable in that it is stable against separation and does not require expensive orange oil which normally must be present in the amount of 0.025%

A surprising effect is that although the drink has a specific gravity of about 1.05 and the terpenes have a specific gravity of about 0.84 there will be no separation of the oil or terpenes.

In lieu of the antioxidants above disclosed, it is also possible to use butylated hydroxy toluene, propyl gallate 'or nordihydroguaiarelic acid.

The preferred ester gum is glyceryl triabietate although glyceryl diabietate may also be used in smaller quantities.

These abietates should be prepared by steam stripping.

The preferred concentrate is an anhydrous thick viscous pourable oil containing less than 5% of water and it is usually substantially flavorless. While there has been herein described a preferred form of the invention it should be understood that the same may be altered within the scope of the appended claims.

Having now particularly described and ascertained the nature of the invention, and in what manner the same is to be performed.
