Description

The chewing gum and the production method thereof that contain the high-potency sweetener that applies zeins

Present patent application is the follow-up of No. 921,754, U.S. Patent application, and above-mentioned application is submitted on October 22nd, 86 with same inventor of the application and assignee, at this, can consult the full content of this patent application.

What the present invention relates to is the method for producing chewing gum, and more particularly, what the present invention relates to is the method for producing the chewing gum that contains high-potency sweetener, and wherein, sweetener through handling, has improved storage-stable and/or can control release.

In recent years, people are striving controlling the release characteristics of various compositions in the chewing gum always, it should be noted that especially, people are attempting to postpone the sweetener in the various chewing gums and the release of spices, prolong chewing the time of sugared body with this, the delay of sweetener and spices discharges can be avoided just chewing at the beginning, and sweet taste and fragrance are just crossed by force and discharged too quickly.On the other hand, but to be handled, so that increase their rate of release in chewing gum some composition.

In addition, people also try hard to protect the high-potency sweetener in the chewing gum formulations, increase the storage-stable of composition with this, promptly prevent to degrade after high-potency sweetener from depositing a period of time.

For example, people such as Sharma are at US4,597, a kind of method of production agglomerated sweetener has been proposed in 970, wherein, it is that the matrix that this method introduction adopts spray congealing step will contain sweetener becomes droplet-shaped on the hydrophobic matrix formed of 25～100 ℃ wax that sweetener is dispersed in basically by lecithin, glyceride and aliphatic acid or fusing point, with after fluid bed be coated in for the second time on the particle of institute's agglomeration.

Two pieces of patent US4 of people such as Merritt, 515,769 and US4,386,106 have provided the two step method that a kind of preparation has the chewing gum spices that postpones release performance, and in the method, spices and hydrophilic matrix are in the emulsion, to grind after the emulsion drying, the particle of gained is coated waterproof material then.

People's such as Sair US4,230,687 introduced a kind of with the effective ingredient encapsulate, so that the method that the composition of the series products of chewing gum discharges gradually, described method comprises adds composition in the cover material of sticky shape to, adopt high speed shear to mix uniform ingredients is dispersed in the matrix, dry thereafter, grind.

People such as Bahoshy are at US4; 139; it is trade name to have provided a kind of " fixing " aspartame(in 639; formal name used at school is that APME-translator is annotated) method; promptly the solution that contains aspartame and encapsulating drug such as Arabic gum is carried out combined drying (adopting spray-drying or fluid bed coating); therefore at duration of storage, aspartame is coated and is protected in colloid.

People such as Cea are at US4, have proposed to utilize various encapsulation techniques with the various solution that contain encapsulating drug in 384,004, as spray-drying, wrap up the method for aspartame, can improve the storage-stable of aspartame like this.

People such as Stroz are at US4, have disclosed a kind of production method of the sweetener that is used for candy such as chewing gum that can control discharges in 634,593, and this method comprises and adopts insoluble fat material and sweetener to mix.

In fact, the sizable equipment investment of arts demand of adopting spray-drying and fluidization to wrap up composition also will have skilled operating personnel and complicated technology controlling and process.

What the present invention relates to is a kind of production method of the chewing gum that contains two coating high-potency sweeteners and the chewing gum of according to said method producing.A certain amount of cated high-potency sweetener particle is mixed the high-potency sweetener that can obtain to have the delay release characteristics with the zein solution of limiting the quantity of.

Limit the addition of zein solution, make the wet mixture of generation have the floating powder of nothing, not flow and easily loose characteristic, with the wet mixture drying, sieve particle then, obtain the two coating high-potency sweetener particles in the predetermined particle size scope thus, thereafter particle is added in the chewing gum formulations.

According to first kind of method for optimizing of the present invention, high-potency sweetener adopts aspartame, in this optimal way, zeins is dissolved in the pH value to be about in 11.5～12.1 the water, and make that its content is about 13～18%(weight in the solution), above-mentioned corn alcohol soup-dissolving protein solution adds by 30～70% the amount that desire is handled aspartame weight, that is to say that the aspartame that finally scribbles zeins preferably contains about 5～25%(weight) zeins.In the method, the chewing gum of being produced has the peppermint local flavor, and contains about 0.1～0.5(weight) above-mentioned coating aspartame.

According to second kind of method for optimizing of the present invention, zeins is dissolved in the ethanol, making its content in solution is about 10～50%, above-mentioned ethanolic solution adds on the aspartame particle of coating in advance by about 25～75% amount of wet mixture, drying, pulverize after, the gained double-coated particles contains about 10～35%(weight) zeins.

According to the third method for optimizing of the present invention, aspartame at first uses as coating materials such as modified celluloses, press and above-mentioned same method coating, more particularly, with aspartame, coating material and the solvent of limiting the quantity of become wet mixture, make the aspartame particle of primary coating again after drying, the pulverizing, handle aspartame particle after first time coating with above-mentioned zein solution then, to make the double-coated particles that on its off-balancesheet surface, has the zeins coating.In this method for optimizing, chewing gum is a Chinese cassia tree fragrance, and contains two coating aspartame of about 0.1～0.5.

One of advantage of the present invention is to apply the storage-stable that zeins can improve aspartame in the chewing gum again on the aspartame of coating that goes ahead of the rest, particularly those contain the chewing gum of aldehyde fragrance component, said stability is highly significant, because contain the fragrance component of aldehyde such as the cinnamic acid in the cinnamon oil is known can react with aspartame, thereby greatly reduced the storage-stable of aspartame in this chewing gum.The test of many times that the applicant did shows that the aspartame of coating can improve its stability in Chinese cassia tree local flavor chewing gum significantly through the zein solution coating more in advance.

The advantage of first kind of method for optimizing is to need not to utilize ethanol to make solvent, and use the aqueous solution of zeins can make zeins be coated in chewing gum with on the high-potency sweetener, this has just reduced the cost that uses zeins, also be, opposite with ethanol, when adopting corn alcohol soup-dissolving protein solution, the danger that does not have blast, catches fire and poison.

The present invention also has an advantage, and that has just provided a kind of quite simple and inexpensive method and has come the highly-efficient treatment sweetener, make it in chewing gum, can postpone to discharge, specifically, method of the present invention can be in the quite short time, utilize easy and inexpensive relatively equipment to implement, surprisingly with the prepared coating high-potency sweetener of this easy and inexpensive relatively method, its storage-stable is similar to unexpectedly or more is better than with the very complicated and expensive handled composition of method.

It also is wonderful that the zein solution of high pH value can be used for this point of high-potency sweetener aspartame grain coating, though generally it is believed that aspartame is unsettled in high pH value environment, the aspartame that has found coating in advance there is no tangible degraded generation when being in when PH is about in 11.5～12.1 the zein solution.

The present invention can implement with continuity method, but is applicable to batch process too, and this is particularly outstanding advantage for a small amount of high-potency sweetener that generally is used for chewing gum formulations.

Should note; " postponing to discharge " used in this specification is meant when chew gum; the delay of high-potency sweetener discharges; also refer to simultaneously when storage; the delay of high-potency sweetener or retardance discharge in the chewing gum; promptly at duration of storage, the protection high-potency sweetener is not subjected to the effect of other composition." storage-stable " is meant in chewing gum during storage can stop the wherein degraded of high-potency sweetener.

It shall yet further be noted that " zeins " used in this specification and claims refers to the mixture of zeins and solvent, wherein zeins or dissolving fully, perhaps most of dissolving, all the other fractions are suspended in the solvent.

Should note in addition, " coating granule " refers to has the coated high-potency sweetener particle of the coated material of part at least, this coating can be pressed and state in the specification relevant zeins coating way and finish, or technology such as spray-drying routinely, and fluid bed coating etc. similarly method are finished." two coating " refers to the particle that passes through primary coating at least, again by the inventive method zeins coating.

Below in conjunction with accompanying drawing the preferred method of the present invention is described, above-mentioned these advantages of the present invention and other advantage will be clearer.

Fig. 2 is the schematic diagram of second kind of method for optimizing of the present invention.

Fig. 3 is the schematic diagram of the third method for optimizing of the present invention.

Fig. 4 is the microphoto of untreated aspartame crystal.

Fig. 5 is for having carried out the microphoto of the aspartame crystal of two coatings by the third method for optimizing of the present invention shown in Figure 3.

Referring to accompanying drawing, Fig. 1 is the production process block diagram of first kind of method for optimizing of the present invention.At first prepare corn alcohol soup-dissolving protein solution.

Zeins is the prolamin of separating from corn, be typically, the zeins that is obtained is Powdered, yellow, tasteless, and is usually water insoluble and be dissolved in alcohol, and used zeins is purchased the company in Freeman in most preferred embodiment.

Known zeins in the past is commonly used for coating material, yet, in these uses, generally it is dissolved in the ethanol, in fact, use ethanol that the danger of optional equipment to reduce blast, to catch fire or poison need be installed.

First kind of implementation method used the aqueous solution of zeins, then avoided the problems referred to above.Because the aqueous solution can maintain between the higher pH value promptly about 11.5～12.1, so can make the aqueous solution of zeins.Have found that zeins obviously increases than dissolubility in neutral water in this PH scope.Generally, when mixing with neutral water, zeins can float on water surface, rather than solution, even can not form the water slurry of zeins, therefore, can not come coated particle with the neutral aqueous solution of zeins.

On the contrary, when when pH value is about 11.5～12.1 water and mixes, just can obtain the aqueous solution and the suspension of zeins, its concentration of the aqueous solution that particularly has now found that zeins can be heavy up to 25%(), in concentration is 25% o'clock, most of zeins has dissolved, and only has sub-fraction to be suspended in the solution.

The preparation of corn alcohol soup-dissolving protein solution is that the zeins of the amount of requirement and the alkali that are enough to make pH value reach about 11.5～12.1 amounts are joined in a certain amount of water, preferably the NaOH of q.s is added to make pH value in the entry between 11.6～11.9.Under stirring condition, to add zeins simultaneously and alkali is advisable, in addition, also can add zeins earlier or add alkali earlier, and then add another kind of.The alkali that other food is suitable for also can use.

Generally, it is heavy that the aqueous solution of zeins should contain 1～25%() zeins, be preferably zeins content about 5～20%(weight) between, be more preferably 13～18%(weight), 16%(weight preferably), as mentioned above, the content of the content of zeins when to be higher than those be not the high pH value aqueous solution in the high pH value aqueous solution.

Again with reference to figure 1, a certain amount of high-potency sweetener particle of coating is in advance joined in the mixing drum of planetary-type mixer, said high-potency sweetener can be selected in various high-potency sweetener, as aspartame, alitame, acesulfame K, sucralose, asccharin and salt, cyclohexane sulfamic acid and salt thereof, dihydrochalcone, Suo Mating (thaumatin) and monellin etc.

Being used for preferred high-potency sweetener of the present invention is dipeptide sweetener, as aspartame or alitame, best dipeptide sweetener is aspartame, it is L-aspartoyl L-phenyalanine methyl ester, used aspartame purchases the company in NUTRASWEET in the most preferred embodiment, and product are called " Nutra SweetR. ", and it is a kind of needle crystals, usually exist with powdery form, have the particle size of relative broad range.

Fig. 4 is a microphoto that amplifies 100 times, and it has provided the shape of aspartame crystal before handling with the inventive method, and just as can be seen, crystalline phase is worked as little and is aciculiform.It has been generally acknowledged that this powder intractable, because its mobile difference and bulk density are low, because their sizes are little and be aciculiform, is quite difficult for these single aspartame crystal coatings therefore particularly.

Used dipeptides high-potency sweetener is L-aspartyl-D-alanine 2,2 in other preferred embodiments, and 4,4 tetramethyls-thiophene-carboxamides are commonly referred to as alitame.

In other preferred embodiment, used high-potency sweetener is the 6-methyl isophthalic acid, 2, and 3-evil thiazine-4(3H)-and ketone-2, the sylvite of 2-dioxide is commonly referred to as acesulfame K.

The present invention also can use more than one high-potency sweetener simultaneously, be that two or more high-potency sweetener can be crossed in Cheng Qian or the process in this method and mixes, that is to say, two kinds of different sweeteners can be mixed to obtain optimal sugariness, can cover similar problems such as unfavorable aftertaste according to the high-potency sweetener that prior art is mixed as can be known.

Before with the inventive method coating, it also is that the present invention is admissible that filler is used in combination with high-potency sweetener.This is desirable especially when use has the high-potency sweetener of the Suo Mating of the high sweetness ratio of every gram or monellin and so on.

The present invention can also further consider that a certain step in this method mixes spices and high-potency sweetener, might produce when chewing sugared body with this method, and high-potency sweetener and spices all can postpone the double-coated particles of release.

Part as the inventive method, high-potency sweetener particle coating in advance before applying with zeins, the coating technology of existing many granular sweeteners, the method for optimizing for preparing the coating granule of going ahead of the rest is at U.S. Patent application 921, disclosed in No. 754, the application is its subsequent application, can consult above-mentioned application at this.According to the description of most preferred embodiment in the above-mentioned application for patent, the high-potency sweetener particle preferably scribbles the aspartame particle of modified cellulose compound, and this method will be discussed further in conjunction with Fig. 3.

Used coating high-potency sweetener particle also can adopt other technology to come coating in this method, these technology comprise, but be not limited to this, for example spray-drying, spraying cooling and fluid bed coating use one deck high-potency sweetener particles above coating or more than one coating materials also to belong to scope of the present invention.

Various coating materials all can be used for applying granular sweetener in advance, and coating material is a modified cellulose compound preferably, preferably hydroxypropyl methylcellulose.

In addition, coating material also can be selected from following material: natural gum, shellac, zeins, maltodextrin, gelatin, starch, lactose, and their composition.

Refer again to method for optimizing as described in Figure 1, the zein solution of limiting the quantity of is added in the high-potency sweetener of the in advance coating in the mixing drum, the addition of zein solution depend on zeins in the solution content and by this method for the second time coating high-potency sweetener the amount of the zeins that applies of requirement.

Also to limit the consumption of zein solution consciously, so that make and do not have floating powder, do not flow, can not push, easily loose wet mixture, " easily loose " speech is meant that wet mixture self is easy to separately, as a comparison, wet mixture should have wet husky the same density and structure, on the contrary, wet mixture should not contain too many solution, otherwise they can become and resemble dough/pasta, paste, sample such as clay or soup has been found that if mixture has arrived the degree of dough-like, will lose plurality of advantages of the present invention so, particularly, the aggregate sample of dough-like is difficult to mix, and handles, drying, and very be difficult to reach desired particle size.

Adding the preferred approach of zein solution in the high-potency sweetener of the coating of going ahead of the rest is under continuous mixing condition, adds from less to more at interval according to certain hour.When adding solution in this way, require before adding following part solution, mixture to be mixed, in following preferred approach, the mixed lentamente thing of the solution that is added is absorbed, and unlikely formation solution pool make the bulk noncombustibility that produces the clay sample in the mixture.

Had been found that a kind of assay method, whether ie in solution has added capacity, and the consumption of measuring powder in the blender then can.Specifically, when mixture becomes the state of dough-like by desired wet mixture state, the powder consumption will increase significantly.It is believed that this be because, when desired wet mixture state, mixture is easily loose, promptly be easy to separately, and when mixture during near the state of clay sample, mixture becomes and has more cohesive, thus can measure the amount of powder that is consumed in blender, and begin should stop to add solution immediately when significantly increasing when the powder that consumes.

By the state of visual observation wet mixture also can determine add the Sq of solution, the feature of as above mentioning is not had floating powder, do not flow and easily loose etc. all observes than being easier to, and is easy to compare with cohesive, the flowability of dough-like state.

Yet, in case after with regard to a certain specific zeins content and zeins the specified weight ratio of high-potency sweetener having been determined best solution usage, the optimum amount of this solution is reproducible.

In method for optimizing shown in Figure 1, added zein solution offer is 30～70% of a wet mixture weight, and is preferably about 40～60%, and optimum value is about 50%.

When zeins is to the relative scale of high-potency sweetener in selecting final products, the factor of considering is: selected concrete high-potency sweetener, to desired release characteristics of two coating sweeteners or the storage-stable in the specific chewing gum, generally, when chewing sugared body, used zeins is many more, and the storage-stable of high-potency sweetener is just good more.

Certainly, the consumption of zeins should remain under the prerequisite that does not influence the chewing gum structure, is preferably, and zeins should be the about 5～25% of coating high-potency sweetener weight, that is, high-potency sweetener and zeins add percentage by weight together.In preferred example, in the high-potency sweetener weight of agglomeration, it is about 8～20% that zeins adds to, and best is 10～16%.

After in the end a part of solution adds, continue to stir the mixture a period of time to being enough to form homogeneous body, specifically, dissolving and undissolved high-potency sweetener, dissolving and undissolved zeins and free water all should be uniformly dispersed in mixture, and the Best Times of mixing can visually determine.

For the present invention, mixed type is important to the influence of mixture, furtherly, it is extremely important to be sure of that adding pressure type mixes, it can impel lysed zeins and the high-potency sweetener particle group of formation together, in contrast, adopts high speed shear formula mixing energy that the component of wet mixture is separated, therefore, preferred mixer types is that planetary-type mixer or other kind are similar to the blender that adding pressure type mixes.

After final the mixing, with the wet mixture drying, preferably water nearly all in the mixture is all removed, realize that dry preferable approach is to take out wet mixture from the mixing drum of blender, then with its spreading in basin, have now found that, preferably serve as a contrast in the basin and go up paper, be convenient to the product that drying is good like this and take away, in preferred example, wet mixture spreading on dish becomes dark about 1～2cm.

Preferably basin is put in the drying oven, placed time enough at a certain temperature so that remove all basically water.Nature, baking temperature and time will be depended on the water yield used in the mixture, also depend on the factors such as hot or wet stability as high-potency sweetener, therefore, also allow dry wet mixture under environmental condition.In preferred example, it is heavy to be coated with 13%() aspartame of zeins be about 170 °F dry 16～20 hours down.

In first kind of method for optimizing, the water content of dried coating aspartame is 2～5% of a gross weight, water content residual in the high-potency sweetener particle of agglomeration can be higher or lower than above-mentioned content, this depends on the character of high-potency sweetener, in fact, if high-potency sweetener goes bad because of water exists, it is just extremely important to remove more water as much as possible, for example, known aspartame when having moisture content to exist with regard to less stable, for this reason, in using the preferred embodiment of aspartame, require to remove as much as possible to anhydrate as high-potency sweetener.

After the drying, general mixture be characterized as different shape or size stiff, based on this, drying composite extremely is convenient to handle, thereby obtain the particle size in institute's claimed range, can in all sorts of ways and finish this work, preferably dried mixture be put into grinder and wear into granule, other device also can be used to grind dried mixture as the roll flour mill.One screen cloth preferably is housed to pass through satisfactory particle on grinder or other device.If desired, can adopt other technology such as secondary screen net or cyclone separator to guarantee maximum particle size and smallest particles size.Select for use the screen cloth in 0.04 inch aperture can obtain desired couple of coating aspartame of first kind of method for optimizing particle.

In first method, only control maximum particle size and get final product, that is to say that smallest particles does not block, its result also has unconjugated small crystals except bigger coating granule group.It is believed that this result is good for the concrete high-potency sweetener in some chewing gum formulations, for example, in first kind of method for optimizing, can affirm some than granule and/or unconjugated aspartame particle when chewing sugared body than discharging quickly in conjunction with agglomerating particle.This release profile makes the consumer feel enough sweet tastes all along.

In further embodiments, require the minimum and maximum particle size of control,, when requiring all high-potency sweeteners to have more consistent delay release performance, need so to obtain particle size than close limit.

At this moment, be easy to the above-mentioned high-potency sweetener that scribbles zeins is made chewing gum.As if other composition is not really important to the present invention in the chewing gum, the high-potency sweetener particle that promptly scribbles zeins can method routinely mix in traditional chewing gum formulations.In fact preferably chewing gum formulations is the chewing gum of sugar-free, yet high-potency sweetener also can be used for containing the chewing gum of sugar to strengthen or/and prolong its sweet taste.The high-potency sweetener that scribbles zeins can be used for common chewing gum, also can be used for bubble gum.

Generally speaking, typical gum components comprises water miscible filler part and water-insoluble masticable basic sugared body portion and typical water-insoluble spices.After chewing after a while, water-soluble portion and part spices have consumed, and basic sugared body portion is still stayed in the mouth for chewing.

Insoluble basic sugared body generally comprises the elasticity thing, resin, grease, wax, softening agent and inorganic filler.The elasticity thing can comprise polyisobutene, isobutylene-isoprene copolymer, styrene butadiene ribber and Heveatex such as tunny gum.Resin comprises polyvinylacetate and terpene resin.Grease can be included in the basic sugared body, and it comprises as tallow, hydrogenation or partially hydrogenated vegetable oil, cocoa butter.Normally used wax comprises paraffin, crystallite and native paraffin such as beeswax and Brazil wax.According to preferable methods of the present invention, insoluble basic sugared body accounts for 5～95% of chewing gum weight, and preferable scope is that 10～50%(is heavy), it is heavy that optimum range is about 20～35%().

Basic sugared body generally also comprises the filler component, and the filler component is calcium carbonate, magnesium carbonate, talcum powder, Dicalcium Phosphate or the like, and filler can account for 5～60% of basic sugared body gross weight, and preferred range is 5～50%(weight).

Typical basic sugared body also comprises softening agent, and it comprises glycerine monostearate, glycerine triacetate.In addition, basic sugared body also comprises some other components (also can not containing) as antioxidant, colouring agent and emulsifying agent.The present invention can consider to adopt the acceptable basic sugared body of any commerce.

The water-soluble portion of chewing gum can further comprise softening agent, sweetener and spices and bond thereof, adding softening agent in the chewing gum is in order to improve chewiness and mouthfeel, softening agent is also referred to as plasticizer in the prior art, its content generally accounts for 0.5～15.0% of chewing gum gross weight, and the used softening agent of the present invention comprises glycerine and lecithin and composition thereof.In addition, comprising the edulcorant aqueous solution of sorbierite, hydrogenated starch hydrolysate, corn syrup and composition thereof can be as the softening agent and the adhesive of chewing gum.

As mentioned above, coating high-potency sweetener of the present invention preferentially is used for the chewing gum formulations of sugar-free, but, contain the sugar prescription also within the scope of the invention, sugar sweetener generally comprises those known sugar of chewing gum field, these components comprise (but being not limited to this) sucrose, glucose, maltose, dextrin, dry powder invert sugar, fructose, laevulose, galactolipin, primverose starch or the like, can be separately or arbitrarily combination make and close.

The high-potency sweetener that scribbles zeins of the present invention also can be used in combination with other non-sugar sweetener, general non-sugar sweetener comprises that those have sweet taste but the component of the characteristic of known sugars not, it comprises following material but is not limited to this, sugar alcohol such as sorbierite, sweet mellow wine, xylitol, hydrogenated starch hydrolysate, maltitol etc. can be used in combination separately or arbitrarily.

The high-potency sweetener that scribbles zeins of the present invention can also be used in combination according to the sweetener of the release profile of concrete sweetener and needed storage-stable and coating not or by the high-potency sweetener that other technology scribbles other material.

Spices consumption in the chewing gum is between 0.1～10.0%, be preferably 0.5～3.0% of chewing gum weight, spices can comprise essential oil, synthetic perfume or its mixture, these include, but are not limited to this: from the essential oil such as the citrus oils of plant and fruit, fruit essence, peppermint oil, spearmint oil, caryophyllus oil, wintergreen, fennel celery or the like, synthetic perfume also can be considered.Natural and synthetic perfume known in the prior art can mix use, as long as can accept on the sense palace.All these spices and potpourri are all within limit of consideration of the present invention.

The spices that is used for chewing gum of the present invention comprises the fragrance component that contains aldehyde, the example of this class spices includes but not limited to this: contain cinnamic acid cinnamon oil, contain benzaldehyde cherry flavor, contain citral and citronellal lemon flavouring, contain the vanilla flavor of vanillic aldehyde and Ethyl vanillin, the fruit flavor that contains acetaldehyde contains the citrus spices of undecyl alcohol and lauric aldehyde.Other contain aldehyde spices can be in following book the 325th～328 page find: " spices technology: distribution, product, application " (author HenryB.Heath, M.B.E., B.Pharm, 1978 by The AVI Publishing Co, Inc.of Westport Conn. publishes), can consult relevant page or leaf content at this.The best spices that is used for chewing gum is cinnamon flavor, and it contains cinnamic acid.

Outstanding advantage of the present invention is to contain in the presence of the aldehyde fragrance component, and the zeins coating has been strengthened the stability of dipeptide sweetener.As mentioned above, that use in the past is the aspartame that does not add protection, contain aldehyde spices in the presence of, degraded can take place and lose sugariness in aspartame.

Also can join in the chewing gum such as inessential compositions such as colouring agent, emulsifying agent and medicaments.

Generally, the production of chewing gum joins various chewing gum components in order to mix in the known commercially available blender of a kind of prior art and makes, after various compositions are thoroughly mixed, from mixer, shift out sugar group, and make it to become desired shape, as roll up tablet forming, and cut into inch strips again, be squeezed into rod or be cast into granular.

Generally, at first with basic sugared body fusing, then it is added in the blender of running so that various composition mixes, basic sugared body also can melt in blender.Colouring agent and emulsifying agent also can add simultaneously, softening agent as glycerine and so on can add in the blender together with syrup and a part of filler at this moment, then another part filler is added in the blender, add spices and last part filler again, add again after of the present invention pair of coating sweetener is preferably in spices and the adding of last part filler.

Whole mixed process needs 5～15 minutes, but also needs longer incorporation time sometimes, and those skilled in the art knows that said process can have various variations.

Referring now to Fig. 2, it has described second kind of method for optimizing of the present invention, this method is except zeins is dissolved in ethanol but not the high PH water, other is all identical with the described method of Fig. 1, furtherly, the zeins powder is dissolved in 95% food-grade ethanol (available from the chemical company of AAPER alcohol, the name of an article " ethanol-U.S.P.95%; 190 proof-spirit degree "), this ethanol/zein solution contains about 10～50%(weight) zeins, preferred range is 20～45%, and the best is 35%, and the content of zeins changes with final two desired zeins amounts of coating high-potency sweetener particle in the above-mentioned ethanolic solution.

The amount of adding the ethanol/zein solution in the coating granule to is about 25～75% of a wet mixture weight, preferred range is about 30～60%, the best is about 42%, as first kind of mode of priority, need the addition of restriction zein solution, so as to make do not have floating powder, do not flow, can not push, easy loose wet mixture.

This wet mixture spreading in aforesaid dish, is carried out drying to remove all basically ethanol, and because of using ethanol, drying time and temperature are all lower, and specifically, baking temperature is 150 °F, and be 12 hours drying time.

Refer now to Fig. 3, it has described the third method for optimizing of the present invention, in the third method, before with the zeins coating, high-potency sweetener is at first by Application No. 06/921, method described in 754 is carried out agglomeration, and the application is the follow-up of above-mentioned application, sees also above-mentioned application at this.According to the disclosed preferred forms of this application for patent, high-potency sweetener preferably aspartamt and and modified cellulose compound, as the hydroxypropyl methylcellulose agglomeration.

In more detail, aspartame and about 15%(weight) the hydroxypropyl methylcellulose agglomeration, this method is with about 85%(weight) aspartame and about 15%(weight) hydroxypropyl methylcellulose place the mixing drum of described hobart blender to do mixing, add water gradually and in mixture, reach about 25% up to mixture is moisture, then with this wet mixture spreading in basin, in about 170 °F dry 12～14 hours down.It is heavy that the water content of dry back mixture is about 2～3%(), dried mixture is taken out from dish, put into again and have 0.04 " the fitzmill flour mill of screen cloth grinds.

The coating aspartame that will so make is by same method noted earlier then, handle with zein solution, preferably handle with above-mentioned high pH value corn alcohol soup-dissolving protein solution, that is to say, a certain amount of coating aspartame is dropped in the mixing drum, under the situation of blender running, add zein solution gradually increasedly then, zeins content, the solution amount in the pH value of its solution and the adding blender is all with noted earlier identical.Mixture is taken out, and spreading carries out drying with same temperature and time in basin, and dried mixture grinds as stated above, makes the aspartame particle of two coatings thus.

Fig. 5 is method for optimizing for this reason, i.e. the microphoto of the product of method shown in Figure 3.Specifically, the aspartame particle is at first with about 15%(weight) the hydroxypropyl methylcellulose coating, particle with about 66 parts of weight is a 16%(weight with the concentration of about 34 parts of weight subsequently) zein solution mix, therefore wet mixture contains about 56%(weight) aspartame, about 10%(weight) zeins hydroxypropyl methylcellulose, about 5%(weight) and about 29%(weight) water.This mixture is dried to water content is about 5%, the result, dried particle contains about 77%(weight) aspartame, about 14%(weight) hydroxypropyl methylcellulose, about 7%(weight) zeins, about 2%(weight) water.

Be surprised to find that, be particularly suitable for the chewing gum of Chinese cassia tree fragrance by two coating aspartame products of this method for optimizing acquisition, as above mention, when aspartame is used for the chewing gum of Chinese cassia tree fragrance, it is a rather unstable, it is believed that this be because the aspartame molecule be present in the result that the fragrance reaction has taken place to go for aldehyde radical in the cinnamon oil.The inventor observes, method according to application for patent, aspartame with the modified cellulose compound agglomeration is unstable especially when being used for Chinese cassia tree local flavor chewing gum, in addition, the inventor also finds, the aspartame particle of coating is not when using the aqueous coating of zeins, the aspartame that promptly is used for the cinnamon flavor chewing gum only scribbles zeins and does not also demonstrate enough stability, yet but find to handle with modified cellulose compound earlier as aspartame, after the above is handled with zeins for another example, at this moment when aspartame was used for Chinese cassia tree fragrance chewing gum, its stability was obviously improved.
