Description
11~5194 YD16b The present invention relates to a long-lasting flavored chewing gum which contains gum base, and a non-sugar sweetener, such as a saccharin sweetener, coated or codried with a filler, such as calcium carbonate, and to a method for preparing such gum.
Conventional chewing gum generally includes gum base composed of ester gum, polyvinyl acetate, latex solids, fatty acids, natural and/or synthetic rubbers, waxes and texturizers and bulking agents, water-soluble flavoring and water-soluble sweeteners, for example, various sugars such as sucrose and dextrose, and/or artificial sweeteners such as sodium or calcium saccharin, cyclamates, dihydrochalcones, glycyrrhizin, glycyrrhizinates, emulsifiers such as lecithin, mono- and diglycerides, and flavors. Such gum initially provides a desirable strong sweet taste which declines rapidly during the first three to five minutes of chewing to a very slight, non-pe~ceptible level of sweetness and flavor.

-2- YD16b that remains in the mouth is an essentially tasteless wad which provides little in the way of flavor, aroma or sweetness. Accordingly, there clearly is a need and long-felt want for a chewing gum which possesses long-lasting flavor and sweetness.
It has ~een found thaL the sweetness and flavor of chewing gums such as non-sour flavored (mint), fruit flavored and sour chewing gums can be prolonged by codrying or coating relatively small amounts of a non-sugar sweetener, such as a saccharin sweetener, with relatively large amounts of a filler, and then substantially uniformly dispersing such combination throughout the gum base. The non-sugar sweetener is thereby substantially bound up and retained in the gum base matrix and during chewing the non-sugar sweetener undergoes slow and controlled release into the saliva.
The filler which also serves as a texturizer is substan-tially insoluble and thus is not released from the gumduring chewing. In effect, the filler spreads out or increases the surface area of the non-sugar sweetener;
thus when the codried combination is incorporated into a chewin~ ~um, the release of the non-sugar sweetener fro~
the gum is si~nificantly slowed down. Furthermore, 1~51~

the filler is substantially retained in the gum base even durinq chewing.
In a Preferred embodiment of the invention, saccharin or aspartame sweetener is codried with calcium carbonate and/or magnesium trisilicate and the resulting combination is dispersed in the gum base.
It is well known that fine pulverization of crystals of poorly soluble materials or even slowly dissolving materials of good solubility increases surface area thereof, which, in turn, increases 51~1~
YD16b solubility rate. However, it has been suprisingly and unexpectedly found that finely divided artificial sweeteners, such as finely powdered free saccharin acid or finely powdered saccharin salts, when incorporated into chewing gum base do just the opposite; the extraction rate of such sweeteners from the gum base during chewing is reduced with decreasing particle size~ so that the sweet taste and flavor of the gum are porlonged. The codrying or coating of the sweetener on the chalk or starch or other fillers has the effect of increasing surface area of the sweetener (and thus, in effect, reducing particle size thereof) thereby resulting in controlled release of sweetener.
The terms "coat", "coated", "coating", "codried, codrying" and these terms having other suffixes as employed herein are intended to refer to the incorporation in or application of the non-sugar sweetener to the filler by dissolution, dispersion, integration, encapsulation or any other conventional technique of physically combining the artificial non-sugar sweetener and filler.

-4-The chewing gum of the present invention, on the other hand, which contains the non-sugax sweetener incorporated with the inorganic or organic filler component, provides a chewing gum whose sweetness corresponds to that of conventional gum for the first 3 minutes but, thereafter, begins to drop more slowly and stabilizes after about 5 minutes of chewing at a desirable sweetness level. This sweetness level remains essentially stable for 15 to 20 minutes. In the chewing gum of the invention, during the first few minutes of chewing, the perceived sweetness is due mostly to sugars or sugar alcohols, or soluble artificial sweeteners ~not combined with the filler) present in the chewing gum.
Thereafter, the non-sugar sweetener combined with the filler is released, flavor is stabilized and the sweet taste persists for extended periods of chewing of up to 20 minutes.
In view of the above, it will be appreciated that by incorporating the non-sugar sweetener with the filler, in accordance with the invention, the initial sweetness impact of the sweetener is reduced or delayed. Thus, the sweetener incorporated in the filler may be used in sugar or sugar alcohol or artificial soluble sweetener-containing chewing gums where a second burst of sweetness from the non-sugar sweetener-filler combination is desired to produce a long-lasting flavored gum which will not have the over-powering sweetness which would normally result where uncoated sweeteners and sugar are employed together.

114S1~34 ~5~ YD16b In formin~ the non-sugar sweetener combination with the filler, the non-sugar sweetener will be employed in a ~eight ratio to the filler of within the range of from about 1:100 to about 1:1, and preferably from about 1:100 to about 1:10, so as to provide a concentration of non-sugar sweetener in the filler preferably within the range of from about 1% to about 10~ by weight of the filler.
The non-su~ar sweetener combined with the filler as discussed below will be present in the chewing gum in an amount within the range of from about 3 to about 0.2~ and preferably from about 3% to about 0.5~ by weight of the gum base, and will be present in the finished chewing gum in amounts ranging from about 1% to about 0.04% and preferably from about 0.6~ to about 0.1%. Examples of non-sugar sweeteners suitable for use herein to be codried or coated on the filler include free saccharin acid (free saccharin acid may react with chalk to produce calcium saccharin), sodium, calcium or ammonium saccharin, sugar alcohols such as xylitol, sorbitol, mannitol or maltitol, cyclamate salts, dihydrochalcones, glycyrrhizic acid and salts, L-aspartyl-L-phenylalanine methyl ester (aspartame) and mixtures thereof.
The filler which is combined with the non-sugar sweetener will be present in the gum in an amount within the range of from about 5 to about 9S% by weight of the gu~ base and preferably in an amount within the range of from about la to about 30~. Examples of fillers suitable for use herein include inorganic fillers such as calcium carbonate, magnesium trisilicate, talc, diatomaceous earth, aluminum oxide and mixtures thereof.

-6- ~D16b It will be understood that the non-sugar sweetener may be codried, coated, incorporated, entrapped, dissolved, dispersed, or otherwise combined with the filler employing conventional coating, drying or encapsulation technology.
In one embodiment, the non-sugar sweetener (e.g., Ca or Na saccharin salt) is dispersed (and preferably solubilized) in water, and mixed with filler such as chalk to form a uniform paste which is then dried and ground to a powder, for example less then 50 mesh, and preferably less than 100 mesh. The powder can then be incorporated with the gum base components or mixed with the gum base as will be described hereinafter together with other conventional chewing gum components to form a chewing gum.
It will also be appreciated that the non-sugar sweetener-filler combination of the invention may be employed in chewing gum which includes sugar and/or other uncoated artificial water-soluble or poorly water-soluble sweeteners such as free saccharin, saccharin salts, cyclamates, aspartame, glycyrrhizinates, dihydrochalcones and the like.
In general, the gum base is prepared by heating and blendi~lg various ingredients, such as natural gums, synthetic resins, waxes, plasticizers, etc., in a manner well known in the art. Typical examples of the ingredients found in a .
-7- YDl~b chewing gum base are masticatory substancesof synthetic origin such as styrene-butadiene copolymer, isobutylene-isoprene copolymer, polyisobutylene, polyethylene, petroleum wax, polyvinyl acetate, as well as masticatory substances of natural origin such as rubber latex solids, chicle, crown gum, nispero, rosidinha, jelutong, pendare, perillo, niger gutta, tunu, etc. The elastomer or masticatory substance will be employed in an amount within the range of about 5 to about 15~, preferably from about 8 to about 12~, and optimally from about 9 to about 11~ by weight of the gum base composition.
In addition, the gum base will preferably contain a solvent for the elastomer which should have minimal tackifying properties and will preferably comprise hydrogenated ester gum, that is, glycerol ester of hydrogenated rosin and/or dimerized ester gum. However, other solvents may be employed such as pentaerythritol ester gum, polymerized ester gum, and ester gum. The solvent will be employed in an amount ranging from about 10 to about 40~, preferably from about 18 to about 30%, and optimally from about 20 to about 25~ by weight of the gum base.
The gum base may also include a hydrophilic-type detackifier which will sorb saliva and become slippery and is incompatible with the elastomer and solvent for the elastomer. E~amples of such materials suitable for use herein will include vinyl polymers having a molecular weight of not less than 20~0, such as polyvinyl acetate, polyvinyl butyl ether, copolymers of vinyl esters and vinyl ethers.
It will be appreciated that the chalk or any other material . ~, ~5~4 which may be present in the gum base will not serve the function of the inorganic or organic filler coating agent for the non-sugar sweetener and that such filler must be separately combined with the non-sugar sweetener; however, this fraction of the gum base may be used for this purpose by combining the chalk or other filler with the sweetener prior to its incorporation in the gum base.
The gum base may also include hard waxes which serve as lubricants and should have a melting point of above about 65C
and preferably above about 75C. Examples of such hard waxes in-clude candelilla wax, paraffin wax, carnauba wax, ozokerite, ori-cury, microcrystalline wax, and the like. The hard waxes will be employed in an amount within the range of from about 0 to about 50% by weight of the gum base, preferably from about 17 to about 40%, and optimally from about 20 to 30% by weight. The preferred hard waxes are candelilla wax and paraffin wax employed in com-bination so that from 2 to about 8% (based on the weight of the gum base~ of the candelilla is employed with from about 15 to about 30~ (based on the weight of the gum base) of the paraffin wax. The waxes are found to reduce the tackiness of the final gum composition without significantly reducing cohesivity thereof.
The hydrophilic-type detackifier will be employed in an amount within the range of from about 20 to about 40~ by weight of the gum base, preferably from about 25 to about 35%, and op-timally from about 28 to about 32% by weight of the gum base.
The gum base may also include a softening agent and lu-bricant combination which may comprise one or more hydrogenated vegetable or animal fats having a high melting point, that is above about 22C, and preferably '~

`"` ll~S194 -9- YD16b above about 50C; such softening agent and/or lubricant may be employed in amounts ranging from about 0 to about 15%
by weight of the gum base, preferably from about 4 to about 12%, and optimally from about 5 to about 10~.
The gum base will also include an emulsifier to impart hydrophilic properties to the gum base so that saliva will be absorbed thereby making the gum base slippery; the emulsifier will be employed in amounts ranging from about 2 to about 12~ by weight of the gum base, preferably from about 3 to about 8%, and optimally from about 5 to about 7~. Examples of such emulsifiers include glyceryl monostearate, phosphatides, such as lecithin and cephalin, Tweens, Spans and mixtures thereof.
In addition, the gum base may include colorants such as titanium dioxide, plasticizers, such as lanolin, stearic acid, sodium stearate, potassium stearate and the like, antioxidants, in an amount up to about 2000 ppm of the gum base, ~ . .
~ such as butylated hydroxyanisole, butylated hydroxytoluene, . .
and propyl gallate.
The gum base may also contain particles of chalk (CaCO)3 as a bulking agent and texturizer (not combined with the non-sugar sweetener) in amounts ranging from about 0 to about 50%, and preferably from about 0.2 to about 25% by weight of the gum base.

Various synthetic flavors, such as mixed fruit, may also be incorporated in the chewing gum of the invention with or without conventional preservatives.
~ The chewing gum of the invention will optionally, ; and preferably, include an easily extractable or water-soluble sweetener, the easily extractable sweetener being ` 20 present in an amount ranging from about 90 to about 0.05%, preferably from about 90 to about 40% by weight of the final produc to provide an initial burst o sweetness. Such water-soluble sweeteners may include one or more sugars, sugar alcohols, or sugar containing material, for example, monosaccharides, disaccharides and polysaccharides, some examples of which follow:
A. ~onosaccharides of 5 or 6 carbon atoms - arabinose, xylose, ribose, glucose, mannose, galactose, fructose, dextrose, or sorbose or mixtures of two or more of the ~- 30 foregoing monosaccharides.

The sugar alcohols include sorbitol, xylitol or manni-tol.
In one embodiment, sorbitol will be included in combi-nation with sugar as the water-soluble sweetener. In such case, the sorbitol will be present in an amount within the range of from about 2 to about 20% by weight of the chewing gum composi-tion, preferably from about 5 to about 15%, and optimally from about 8 to about 12%.
Furthermore, any of the water-soluble artificial or natural sweeteners set out hereinbefore may be present together with the non-sugar sweetener combined with the filler.

Example l Fifteen grams of sodium saccharin is solubilized in lO0 ml of distilled water. The saccharin solution is added to 270 g of chalk while mixing to form a uniform paste.
The mixed paste is dried to remove the moisture and ground into a powder passing a sieve of lO0 mesh.
An amount of 1230 g of gum base containing 88 parts ester gum, lO parts rubber latex solids, and 2 parts lecithin is melted in a jacketed sigma mixer and 285 g of the chalk and sodium saccharin are added. The mass is mixed thoroughly for 30 minutes while maintaining the temperature at 140 to 180F. The chalk and saccharin containing gum base is removed from the mixer and cooled.
The sodium saccharin is extracted from the gum base in accordance with the following procedure.
An aliquot of 40 g of the gum base is taken and mixed thoroughly in a Waring blender with 200 ml of distilled water. During mixing, the gum base is reduced in size to .a powder form so that an intimate contact is maintained between the gum base and the water. After 5 minutes of mixing, gum base is separated from the water by filtration ` and the aqueous filtrate is analyzed for sodium saccharin using a standard W absorbance method. The gum base is extracted again with 200 ml of distilled water for another
Thereafter, the non-sugar sweetener combined with the filler is released, flavor is stabilized and the sweet taste persists for extended periods of chewing of up to 20 minutes.
In view of the above, it will be appreciated that by incorporating the non-sugar sweetener with the filler, in accordance with the invention, the initial sweetness impact of the sweetener is reduced or delayed.
