"IMPROVED CHEWING GUM CONTAINING 8TRU~K~ LIPID8"
BACKGROUND OF THE INVENTION
Related ApPlication This is a continuation-in-part of PCT application No. PCT/US94/12548 filed on November 1, 1994.
The present invention relates generally to chewing gum. More specifically, the present invention relates to improved formulations for chewing gum and bases.
Chewing gum generally consists of a water insoluble gum base and a water soluble portion along with flavors.
The water soluble portion and flavors dissipate during chewing and the gum base is retained in the mouth throughout the chew.
The insoluble gum base generally comprises elastomers, resins, fats and oils, softeners, and inorganic fillers. Elastomers can include synthetic elastomers including polyisobutylene, isobutylene-isoprene copolymers, styrene-butadiene copolymers, polyvinyl acetate, polyisoprene, polyethylene, vinyl acetate - vinyl laurate copolymers, and combinations thereof. Natural elastomers that can be used include natural rubber.
The gum base can include elastomer plasticizers.
Such elastomer plasticizers can include natural rosin esters, as well as other elastomer plasticizers.
Additionally, the gum base can include fillers/texturizers andsofteners/emulsifiers. Softeners are added to chewing gum in order to optimize the chewability and mouth feel of the gum.
Softeners/emulsifiers that are typically used include tallow, hydrogenated tallow, hydrogenated and partially W O96/13173 PCTrUS95/13951 hydrogenated vegetable oils, cocoa butter, glycerol monostearate, glycerol triacetate, lecithin, and combinations thereof.
In addition to a water insoluble gum base portion, a typical chewing gum composition includes a water soluble portion and one or more flavoring agents. The water soluble portion can include bulk sweeteners, high intensity sweeteners, flavoring agents, softeners, emulsifiers, colors, acidulants, fillers, antioxidants, and other components that provide desirable attributes.

SUMMARY OF THE I~v~NllON
The present invention provides improved chewing gum formulations and bases, as well as methods of producing chewing gum and bases. Pursuant to the present invention, a gum base is provided that includes a structured lipid that contains caprylic or capric fatty acids, for example caprenin (caprocaprylobehenin), as a plasticizer. In an embodiment, the structured lipid comprises only capric and caprylic fatty acids. However, in an embodiment, the structured lipid includes other fatty acids in addition to caprylic and/or capric fatty acids.
In an embodiment, caprenin is added to gum base formulations replacing a small or large quantity of fats, oils, or waxes.
In an embodiment, caprenin replaces, in a gum base formula, at least some of the conventional saturated fats. The caprenin can also be used to improve flavor quality by replacing a portion or all of the other saturated fats in the base formula. Caprenin may also control flavor release and reduce harshness/bitterness of the flavor.

W O 96/13173 PCT~US95/13951 A variety of base and chewing gum formulations including structured lipids, such as caprenin, can be produced and/or utilized pursuant to the present invention. The base formulations of the present invention may be conventional bases that include wax or are wax-free, tacky or non-tacky and/or bubble gum-type bases. The gum formulations can be low or high moisture formulations containing low or high amounts of moisture-contA;n;ng syrup. Caprenin can also be used in low sugar and non-sugar containing gum formulations made with sorbitol, mannitol, other polyols, and non-sugar carbohydrates. Non-sugar formulations can include low or high moisture sugar-free chewing gums.
In an embodiment, caprenin is used in the chewing gum formulation to replace typical plasticizers that are used in chewing gum formulations. For example, caprenin can be used to replace glycerin, lecithin, glycerol triacetate, acetylated monoglycerides, and mono- and di-glycerides.
In an embodiment, the caprenin is used in a chewing gum formulation combined with other softeners, emulsifiers, and plasticizing agents. If desired, caprenin can be used alone or combined with an inert material which may be added in a dry form. The caprenin softener can also be added to the flavor as a carrier for its use in chewing gum.
The caprenin when used according to the present invention, affords the chewing gum an improved texture, improved shelf life, and improved flavor quality. Even though caprenin is similar to other fats and oils in some respects, caprenin has a lower caloric value and creates a resultant chewing gum product that has a high consumer-acceptability.

DETAILED DESCRIPTION
OF THE PRESENTLY PREFERRED EMBODIMENTS
The present invention provides improved chewing gum formulations and base formulations. Pursuant to the present invention, structured lipids that contain caprylic or capric fatty acids are added to chewing gum and base formulations. In a preferred embodiment caprocaprylobehenin (hereinafter referred to as "caprenin") is used. Caprenin can be used in chewing gum CA 02204l4l l997-04-30 W O96/13173 PCT~US95/13951 formulations and/or bases. Preferably the caprenin can be used as a plasticizer in the gum base.
Caprenin being a saturated fatty acid triglyceride can be used to replace other fats in gum base that are also saturated fatty acid triglycerides. Most triglycerides used as fat in gum bases are from fatty acids such as stearic acid (C18), palmitic acid (C16), oleic acid (C18:1 unsaturated) and linoleic acid (C18:2 unsaturated). These common fatty acids are derived from saturated soybean oil, olive oil, canola oil, cottonseed oil, coconut oil, palm oil, corn oil, palm kernel oil, safflower oil, lard, tallow, and a wide variety of short and long chain fatty acids.
Generally, these fats or lipids are hydrogenated to make them saturated for use in gum base. Saturation of the lipids significantly improves their oxidation stability, which is very important for shelf life of gum base and gum. When oil is hydrogenated it becomes a solid at room temperature, thus a fat.
The above identified fats contain a natural fatty acid distribution dependent on its source. When the triglyceride is interesterified the triglyceride is broken down to glycerol and free fatty acids, and is then recombined to provide different triglyceride molecules.
If the fatty acids are separated to specific fatty acids and recombined with glycerol, this is called a structured lipid. One such structured lipid is Caprenin. Caprenin is made with (C8) caprylic, (C10) capric and behenic (C22) saturated fatty acids. This material is created by deriving from rapeseed oil a high quantity of tribehenin, from coconut or palm kernel oils medium chain triglycerides (MCT) are obtained. The tribehenin is interesterified with the medium chain triglycerides to CA 02204l4l l997-04-30 W O 96/13173 PCTrUS95/139 form the caprenin material. Caprenin is available from Procter ~ Gamble Co. of Cincinnati, Ohio.
Although caprenin is a fat, its unique chemical structure gives it unique properties. It has a low caloric value as compared to other fats. This is due to the fact that long chain behenic acid is only partially absorbed by the body and the two MCTs are metabolized like carbohydrates, affording caprenin a lower caloric value. The combination of these three fatty acids gives caprenin a caloric value of 5 calories per gram compared to 9 calories per gram of other dietary fats.
Additionally, caprenin has no tropical oils.
Caprenin is also not believed to increase blood cholesterol levels. In fact, the FDA has excluded these fatty acids from their definition of saturated fats for nutrition labeling.
Structured lipids such as Caprenin may have properties that are different than conventional saturated triglycerides. It has been surprisingly found that Caprenin is a better plasticizer of elastomers used in gum base as compared to conventional saturated triglycerides. It has also been found that fatty acid triglycerides C8 and C10 (Medium Chain Triglycerides or MCTs) are very good plasticizers for gum base elastomers.
The triglycerides from these two fatty acids appear to not only soften the gum base, but also plasticize the rubber elastomer more effectively than conventional triglycerides.
Conventional triglyercides soften gum base by lubricating the rubber elastomers to make the elastomers workable. Plasticizers are more compatible with the elastomer and actually become part of the elastomer matrix to modify its physical properties. It is -W O96/13173 PCTrUS95/13951 speculated that the lower molecular weight medium chain (C8 and C10) triglycerides are able to enter the elastomer structure and modify it, whereas the larger fatty acid molecules (such as stearic and palmitic) are not.
It is believed since Caprenin comprises two parts medium chain triglycerides and one part larger fatty acid, that this allows Caprenin to be a more effective plasticizer than other conventional fats.
An FDA GRAS petition has been filed by Procter &
Gamble Co. for use of caprenin in soft candy, and in confectionery coatings for nuts, fruits, cookies, and the like, including traditional chocolate candy bars. It is believed that caprenin is currently being used in a chocolate bar on the market.
Although the GRAS petition for caprenin does not include its use in chewing gum, the inventors believe that caprenin can be used in base formulations, and/or chewing gum formulations. In this regard, caprenin can be used as a plasticizer. Preferably, caprenin will comprise about 0.01% to approximately 5% by weight of the chewing gum formulation. Caprenin can be used in a variety of different chewing gum and base formulations.
Caprenin has a melting point of about 80-90~F, and would therefore typically be added to the gum base or a gum formulation in its liquid form.
Chewing gum generally consists of a water insoluble gum base, a water soluble portion, and flavors.
The insoluble gum base generally comprises elastomers, resins, fats and oils, softeners, and inorganic fillers. The gum base may or may not include wax. The insoluble gum base can constitute approximately 5 to about 95 percent, by weight, of the chewing gum, W O96/13173 PCT~US95/13951 more commonly, the gum base comprises 10 to about 50 percent of the gum, and in some preferred embodiments, 20 to about 35 percent, by weight, of the chewing gum.
In an embodiment, the chewing gum base of the present invention contains about 20 to about 60 weight percent synthetic elastomer, 0 to about 30 weight percent natural elastomer, about 5 to about 55 weight percent elastomer plasticizer, about 4 to about 35 weight percent filler, about 5 to about 35 weight percent softener, and optional minor amounts (about one percent or less) of miscellaneous ingredients such as colorants, antioxidants, etc. Preferably, the caprenin does not comprise more than 40~ by weight of the gum base.
Synthetic elastomers may include, but are not limited to, polyisobutylene with a GPC weight average molecular weight of about 10,000 to about 95,000, isobutylene-isoprene copolymer (butyl elastomer), styrene-butadiene copolymers having styrene-butadiene ratios of about 1:3 to about 3:1, polyvinyl acetate having a GPC weight average molecular weight of about 2,000 to about 90,000, polyisoprene, polyethylene, vinyl acetate-vinyl laurate copolymer having vinyl laurate content of about 5 to about 50 percent by weight of the copolymer, and combinations thereof.
Preferred ranges are, for polyisobutylene, 50,000 to 80,000 GPC weight average molecular weight, for styrene-butadiene, 1:1 to 1:3 bound styrene-butadiene, for polyvinyl acetate, 10,000 to 65,000 GPC weight average molecular weight with the higher molecular weight polyvinyl acetates typically used in bubble gum base, and for vinyl acetate-vinyl laurate, vinyl laurate content of 10-45 percent.

W O 96/13173 PCTrUS95/13951 Natural elastomers may include natural rubber such as smoked or liquid latex and guayule as well as natural gums such as jelutong, lechi caspi, perillo, sorva, massaranduba balata, massaranduba chocolate, nispero, ros; n~; nh~, chicle, gutta hang kang, and combinations thereof. The preferred synthetic elastomer and natural elastomer concentrations vary depending on whether the chewing gum in which the base is used is adhesive or conventional, bubble gum or regular gum, as discussed below. Preferred natural elastomers include jelutong, chicle, sorva and massaranduba balata.
Elastomer plasticizers may include, but are not limited to, natural rosin esters, often called estergums, such as glycerol esters of partially hydrogenated rosin, glycerol esters polymerized rosin, glycerol esters of partially dimerized rosin, glycerol esters of rosin, pentaerythritol esters of partially hydrogenated rosin, methyl and partially hydrogenated methyl esters of rosin, pentaerythritol esters of rosin; synthetics such as terpene resins derived from alpha-pinene, beta-pinene, and/or d-limonene; and any suitable combinations of the foregoing. the preferred elastomer plasticizers will also vary depending on the specific application, and on the type of elastomer which is used.
Fillers/texturizers may include magnesium and calcium carbonate, ground limestone, silicate types such as magnesium and aluminum silicate, clay, alumina, talc, titanium oxide, mono-, di- and tri-calcium phosphate, cellulose polymers, such as wood, and combinations thereof.
In an embodiment, in addition to caprenin, pursuant to the present invention, softeners/emulsifiers may include tallow, hydrogenated tallow, hydrogenated and W O96/13173 PCTrUS95/13951 partially hydrogenated vegetable oils, cocoa butter, glycerol monostearate, glycerol triacetate, lecithin, mono-, di- and triglycerides, acetylated monoglycerides, fatty acids (e.g. stearic, palmitic, oleic and linoleic acids), and combinations thereof.
Colorants and whiteners may include FD&C-type dyes and lakes, fruit and vegetable extracts, titanium dioxide, and combinations thereof.
The base may or may not include wax. An example of a wax-free gum base is disclosed in U.S. Patent No.
5,286,500, the disclosure of which is incorporated herein by reference.
In addition to a water insoluble gum base portion, a typical chewing gum composition includes a water soluble bulk portion and one or more flavoring agents.
The water soluble portion can include bulk sweeteners, high intensity sweeteners, flavoring agents, softeners, emulsifiers, colors, acidulants, fillers, antioxidants, and other components that provide desired attributes.
The softeners, which are also known as plasticizers and plasticizing agents, generally constitute between approximately 0.5 to about 15% by weight of the chewing gum. The softeners may, in addition to including caprenin, include glycerin, lecithin, and combinations thereof. Aqueous sweetener solutions such as those containing sorbitol, hydrogenated starch hydrolysates, corn syrup and combinations thereof, may also be used as softeners and binding agents in chewing gum.
Bulk sweeteners include both sugar and sugarless components. Bulk sweeteners typically constitute 5 to about 95% by weight of the chewing gum, more typically, 20 to 80% by weight, and more commonly, 30 to 60% by weight of the gum.

CA 02204l4l l997-04-30 W O96/13173 PCTrUS95/13951 ~ Sugar sweeteners generally include saccharide-containing components commonly known in the chewing gum art, including, but not limited to, sucrose, dextrose, maltose, dextrin, dried invert sugar, fructose, levulose, galactose, corn syrup solids, and the like, alone or in combination.
Sorbitol can be used as a sugarless sweetener.
Additionally, sugarless sweeteners can include, but are not limited to, other sugar alcohols such as mannitol, xylitol, hydrogenated starch hydrolysates, maltitol, lactitol, and the like, alone or in combination.
High intensity artificial sweeteners can also be used in combination with the above. Preferred sweeteners include, but are not limited to sucralose, aspartame, salts of acesulfame, alitame, saccharin and its salts, cyclamic acid and its salts, glycyrrhizin, dihydrochalcones, thaumatin, monellin, and the like, alone or in combination. In order to provide longer lasting sweetness and flavor perception, it may be desirable to encapsulate or otherwise control the release of at least a portion of the artificial sweetener. Such t~chn;ques as wet granulation, wax granulation, spray drying, spray chilling, fluid bed coating, coacervation, and fiber extension may be used to achieve the desired release characteristics.
Usage level of the artificial sweetener will vary greatly and will depend on such factors as potency of the sweetener, rate of release, desired sweetness of the product, level and type of flavor used and cost considerations. Thus, the active level of artificial sweetener may vary from 0.02 to about 8%. When carriers used for encapsulation are included, the usage level of CA 02204l4l l997-04-30 W O96/13173 PCTrUS9S/13951 the encapsulated sweetener will be proportionately higher.
Combinations of sugar and/or sugarless sweeteners may be used in chewing gum. Additionally, the softener may also provide additional sweetness such as with aqueous sugar or alditol solutions.
If a low calorie gum is desired, a low caloric bulking agent can be used. Example of low caloric bulking agents include: polydextrose; Raftilose, Raftilin;Fructooligosaccharides(NutraFlora);Palatinose oligosaccharide; Guar Gum Hydrolysate (Sun Fiber); or indigestible dextrin (Fibersol). However, other low calorie bulking agents can be used.
A variety of flavoring agents can be used. The flavor can be used in amounts of approximately 0.1 to about 15 weight percent of the gum, and preferably, about 0.2 to about 5%. Flavoring agents may include essential oils, synthetic flavors or mixtures thereof including, but not limited to, oils derived from plants and fruits such as citrus oils, fruit essences, peppermint oil, spearmint oil, other mint oils, clove oil, oil of wintergreen, anise and the like. Artificial flavoring agents and components may also be used. Natural and artificial flavoring agents may be combined in any sensorially acceptable fashion.
The present invention, it is believed, can be used with a variety of processes for manufacturing chewing gum.
Chewing gum is generally manufactured by sequentially adding the various chewing gum ingredients to commercially available mixers known in the art. After the ingredients have been thoroughly mixed, the chewing gum mass is discharged from the mixer and shaped into the W O96/13173 PCTrUS95/13951 desired form, such as by rolling into sheets and cutting into sticks, extruding into chunks, or casting into pellets.
Generally, the ingredients are mixed by first melting the gum base and adding it to the running mixer.
The gum base may alternatively be melted in the mixer.
Color and emulsifiers can be added at this time.
Molten caprenin in its liquid form may be added to chewing gum during manufacture of the base. Molten caprenin may be added at any time during processing of the base, but preferably, near the end of the batch to act as a softener.
Caprenin may be added to conventional bases that contain wax or are wax-free bases, that may or may not contain polyvinyl acetate or terpene resins, or bases that contain natural gums or synthetic bases, bases that are non-tacky, or are bubble gum bases.
At levels of approximately 0.02% to about 40% by weight of the gum base, caprenin may replace some or most of the partially hydrogenated or hydrogenated vegetable oils, mono- and di-glycerides, acetylated monoglycerides, or other softeners used in the gum base. Caprenin may also be blended with the other softeners in the gum base and added during the base manufacturing process. A
chewing gum base made with caprenin will have greater oxidative stability due to the presence of caprenin, and will give chewing gum a cleaner taste due to a reduction of off-tasting fats and oils.
A chewing gum softener such as glycerin can be added next along with part of the bulk portion. Further parts of the bulk portion may then be added to the mixer.
Flavoring agents are typically added with the final part of the bulk portion. The entire mixing process typically W O 96/13173 PCT~US95/13951 takes from five to fifteen minutes, although longer mixing times are sometimes required.
Molten caprenin may also be added to a chewing gum formulation in its liquid form or may be mixed with other gum or base softeners and added to a gum formulation during processing. Molten caprenin may be added during the gum manufacturing at any time during processing, but preferably, early in the batch to allow thorough mixing with the gum base.
Caprenin can be added to the chewing gum formulation so that it comprises approximately 0.01% to about 5% by weight of the chewing gum formulation. In a preferred embodiment, caprenin comprises approximately 0.02% to about 2% and most preferably, about 0.05% to about 0.5%
by weight of the chewing gum formulation. Caprenin may be blended with other softeners such as lecithin, glycerol triacetate, acetylated monoglycerides, mono- and di-glycerides, or other vegetable oils and fats that may be added to a gum formulation. When a solid softener is used, such as lecithin, molten caprenin may act as a carrier or solvent for the particulate lecithin.
Lecithin when mixed with molten caprenin may allow for an easier dispersion of lecithin in a gum formulation.
This should be contrasted with soy bean oil that is typically used as a carrier for lecithin.
Molten caprenin may also be blended with a wide range of natural and artificial flavor oils and act as a carrier for flavor oils. Molten caprenin can be an excellent carrier for flavors such as spearmint, peppermint, cinnamon, wintergreen, and fruit flavors.
The level of caprenin mixed with flavors can vary over a wide range from approximately 1% to about 99% by weight since most gum flavors are oil soluble.

W O96/13173 PCTrUS95/13951 Caprenin can also act as a carrier for artificial and natural colors such as in FD&C lake dispersions and natural colors like betacarotene. Caprenin can reduce the off-taste associated with some fat/oil carriers and allows higher usage of color.
Caprenin may also be used as a release agent for encapsulated flavors. Caprenin can be added to an encapsulating media to allow for faster and easier dissolution of the encapsulating media.
By way of example, and not limitation, examples of the present invention will now be given:

EXAMPLES
Example No. 1 A method for measuring plasticization effect is the Glass Transition Temperature (Tg) of a material or a blend of materials. If a material acts as a plasticizer to another material, the Tg will be modified accordingly.
In the case of the elastomer butyl rubber, which is an isobutyl-isoprene copolymer, the Tg of a mixture of 25 grams of butyl rubber and 24 grams of calcium carbonate, which is inert, was -61.3~C. The mixture was blended on a Haake Internal Mixer at 130~C, 60rpm for 20 minutes, and analyzed to obtain the Tg by DSC from -160~C
to +100~C at 20~C/minute.
The results shown below are for various materials used as plasticizers added to the above mixture at a level of 11 grams of plasticizer.

Medium Cilain Triglycerides (MCTs) ~8.3~C
Caprenin 64.1~C
CoconutOil ~3.3~C
Hy i~uyel~led Cullonseed Oil ~2.1~C
Structured Lipid (C8/C10/C18:2) 66~C
The results indicate that a typical plasticizer/softener for gum base, hydrogenated cottonseed oil, reduces the Tg of butyl rubber by only 0.8~C. A better plasticizer/softener is coconut oil which contains a significant amount of MCTs and reduces the Tg by 2.0~C. The Caprenin material which takes its portion of MCT from coconut oil is still an even better plasticizer than coconut oil and hydrogenated cottonseed oil.
The results also show that other structured lipids such as Caprenin and C8/C10/C18:2 which contain caprylic and capric fatty acids are also effective as a rubber plasticizer. When the C22 fatty acid is replaced by a lower chain fatty acid such as C18:2,, butyl rubber is plasticized further.
In addition, other elastomers would also be effected in a similar manner as butyl rubber, such as the synthetic elastomer, styrene butadine rubber (SBR).
Natural rubbers such as chicle, jelutong, sorva, and Massaranduba Balata would probably also be more plasticized with Caprenin. r W O96/13173 PCTrUS95/13951 Example No. 2 To demonstrate the plasticizing/softening effect of Caprenin, the following gum formulas were made and tested for Instron Hardness:
