Description

Utilize the coated delayed release ingredients of waxing to prepare the method for chewing gum

The present invention relates to utilize coated delayed release ingredients to prepare the method for chewing gum.

Recent years, people are trying every means always and are controlling the releasing properties of various food ingredients in the chewing gum.The most noticeable is the release of attempting to delay sweetener and spices in the various chewing gum formulations always, prolongs with this that chewing gum is gratifying to be chewed the time.The release that delays sweetener and spices also can be avoided when beginning to chew, undesirable excessive the bursting out of sweetener and spices.On the other hand, some food ingredient wants processed to increase their rate of release in chewing gum always.In addition, in addition some trial is at delaying or stops the release of active batching composition between the storage life in the chewing gum formulations, thereby the long-time stability of increase food ingredient.

For example people's such as Sharma United States Patent (USP) 4597970 discloses the method that a kind of preparation is coated with the sweetener of stain, and sweetener wherein is dispersed in mainly by lecithin, glyceride and aliphatic acid or to have fusing point be in the hydrophobic matrix formed of 25 ℃-100 ℃ wax.The matrix that said method has utilized a kind of congealing step of spraying will contain sweetener becomes droplet, the particle that was coated with the stain through the fluid bed secondary.

People's such as Merrit United States Patent (USP) 4515769 and 4386106 discloses a kind of preparation and has delayed the two-stage process that spices in the chewing gum such as essential oil discharge.Spices is to be prepared in a kind of emulsion that has hydrophilic matrix in the method.Emulsion is dried, grinds, then particle is coated fluid-tight material.

People's such as Sair United States Patent (USP) 4230687 discloses a seed capsules bag active component and has reached and progressively discharge purpose, as the progressively release of the food ingredient in the chewing gum product.Described method comprises food ingredient is added in the capsule material of a sticky shape, utilizes high shearforce to mix and improves the even dispersion of composition in the matrix that will carry out dry and grinding.

People's such as Bahoshy United States Patent (USP) 4139639 discloses a kind of solution " fixing " aspartoyl phenylalanine formic acid that contains L-aspartyl-L-phenylalanine methylester and capsule such as gum arabic by its drying (utilizing the atomizing fluidized bed drying), thereby surrounds and the protection L-aspartyl-L-phenylalanine methylester at the chewing gum storage period.

The solution that people's such as Cea United States Patent (USP) 4384004 discloses the different capsule of a kind of usefulness uses different encapsulation techniques such as spray-drying to come the method for packing L-aspartyl-L-phenylalanine methylester with the bin stability of raising L-aspartyl-L-phenylalanine methylester.

People's such as Stroz United States Patent (USP) 4634593 discloses a kind of method that delays to discharge sweetener of making candies such as chewing gum.The method has been used a kind of and the insoluble fatty material sweetener mixed grinding.

Nature utilizes spray-drying or fluid bed coating solution technology to come all one-tenth of packing branch to cause sizable equipment investment, and requires skilled operating personnel and complicated step control.

The objective of the invention is to improve the method that preparation has the chewing gum of coated delayed release ingredients.Briefly, the inventive method generally comprises the following step.Quantitative powdered ingredient composition mixes the mixture that forms humidity with the wax of fusing, then with its cooling and sclerosis, the mixture of sclerosis is treated, as grinding and/or screening, make the waxing food ingredient particle of desired granular size, the particle of these waxings is added in the chewing gum formulations subsequently.

According to preferred embodiment of the present invention, handled composition is the high-potency sweetener that is called as acesulfamek, and mixing is to finish in the blender of planetary-type mixer or other types.Blender is exerted pressure between each component and is had such as vapour jacket and comes to be the mixing drum heat supply.Better is, wax is melted before adding mixing drum, and acesulfamek was heated to the temperature of the wax that is melted, the preferably amount of the wax of restriction fusing before adding wax, make mixture little just wet or moist, dustless, mobile, frangible characteristic that this moist mixture has.

The present invention has following advantage, promptly provides the method for easy and cheap relatively mixing processing composition to make it to delay in chewing gum to discharge.Method particularly of the present invention can be carried out at the simple relatively equipment of short relatively time utilization.It is shocking that this simple and cheap relatively method can produce and have the food ingredient that the quilt that delays release performance is coated with stain, its performance with become to close similar with batching more complicated and the expensive methods processing.And, though the present invention can be used for the serialization production process, also be well suited for intermittenceization production.For adopting the particularly important of small lot food ingredient.

It should be noted: be meant that at the coated delayed release ingredients described in specification and claims food ingredient has slower release performance than the food ingredient without this processing after treatment.Delaying to discharge a speech in this article also can refer to by stoping or delay the storage stability of this food ingredient of certain food ingredient release in storage increasing in the chewing gum.In other words, the performance that this food ingredient is had delay to discharge can mean that also this food ingredient of protection is not had an effect with other components of chewing gum in the chewing gum storage.

Should also be noted that, this term of said wax means quite wide implication in this specification and claims, comprising various animal waxs, vegetable wax, mineral wax and synthetic wax, as Tissuemat E, paraffin, micro-crystallization wax, beeswax, Brazil wax etc.

The above-mentioned advantage of the present invention and other advantages will become more obvious in the following description, and this description combines with accompanying drawing, disclose present best the inventive method.

Fig. 1 is the schematic diagram of the preferred process of the present invention.

Fig. 2 is the schematic diagram of other method of the present invention.

Fig. 3 represents the curve map of acesulfamek rate of release in the comparison chewing gum.

With reference to accompanying drawing, Fig. 1 is the schematic flow diagram of the implementation step of explanation embodiment preferably of the present invention, at first, a certain amount of powdered ingredient composition is added in the mixing drum.

Optional chewing gum food ingredient such as the sweetener, spices agent, acidulant, medicament etc. from wide region of powdered ingredient, better batching is a high-potency sweetener, as acesulfame, L-aspartyl-L-phenylalanine methylester, alitame, Sucralose, asccharin and salt thereof, cyclohexane sulfamic acid and salt thereof, dihydrochalcone, thaumatin and monellin etc.

In most preferred embodiment, the used high-potency sweetener of the present invention is 6 methyl isophthalic acids, 2, and 3-Evil thiazine-4(3H)-list-2, the 2-dioxide (6-methyl-1,2,3-oxathiazin-4(3H)-and list-2, salt 2-dioxide).So-called acesulfame, the so-called acesulfamek. of its sylvite is the most frequently used salt.Can obtain from HOECHST AG company, trade mark is " sunett ^R".

In other preferred embodiments, high-potency sweetener is the dipeptide sweetener of L-aspartyl-L-phenylalanine methylester or alitame as is known, and this dipeptide sweetener can be that L-aspartyl-L-phenylalanine methylester is a L-aspartyl L-phenyalanine methyl ester.Used aspartame can obtain from NUTRASW EET company, and its trade mark is Nutrasw eet ^RL-aspartyl-L-phenylalanine methylester normally has the powder of the acicular crystal of relative broad range particle.The L-aspartyl-L-phenylalanine methylester crystal is smaller and needle-like, so these powder are because not easy mobility and low volume density, usually be considered to be difficult to utilize, owing to the little and needle-like of its particle, single L-aspartyl-L-phenylalanine methylester is difficult to be coated with stain relatively in addition.

In addition, efficient dipeptide sweetener can be L-aspartyl-D alanine-2,2,4, and 4-tetramethyl-thienyl-acid amides is called alitame usually.

The present invention also considers the food ingredient that adopts more than one, be that two or more chewing gum food ingredients are mixed together before this method is carried out or in the process, for example, desirable way is sweetener and flavouring agent to be mixed to produce make the Wax particles that is coated with that two kinds of food ingredients delay to discharge.In addition, ideal method is that two kinds of different sweeteners are mixed to obtain the best sugariness of synergy and chewing gum, has known that in present technique mixing sweetener can hide unwanted pleasant impression etc.

It also is preferred that high-potency sweetener is mixed with filler, for example when using with a kind of sweetener such as thaumatin or monellin, each sweetener wherein all has about 2000 high-sucrose equivalent, and desirable method is to add a kind of filler such as sweet mellow wine, maltodextrin, Arabic gum, starch, sugar etc.

As mentioned above, the powdered ingredient composition is put into mixing drum, and the wax that is heated to fusing adds fashionable temperature.Have been found that the powdered ingredient composition is useful for method of the present invention under this temperature, because when the powdered ingredient composition is coated with stain, wax keeps molten state.Nature, promptly liquid if wax is not to be in molten state, it is possible being coated with that stain powdered ingredient composition both made, and also is difficult.

In case the powdered ingredient composition is heated to desired temperature, in the wax adding mixing drum with fusing.The wax that the present invention is used should have greater than about 130 fusing point.High relatively fusing point is very important, and this has three reasons at least, and at first high melting-point wax benefits and grinds or the granulation operation, and in other words, high melting-point wax relatively is not easy to soften in typical grinding operation process.

The fusing point of wax should be higher than second about 130 reason, must adopt the wax of higher melt, so that add the particle of waxing in general chewing gum manufacture process.Particularly, by being added to remain on usually in about 110 °-130 fusing matrix, various food ingredients prepare chewing gum.Therefore, if use its fusing point to be lower than the wax of chewing gum preparation temperature, just can not show the advantage that is coated with stain.

Last reason is, use high melting-point wax why important be because its not too easily rheological equationm of state of the final chewing gum product of influence promptly chew character.Particularly in chewing gum formulations, low melt wax is through being often used as softening agent or plasticizer.Yet because its stronger physics inertia, high melting-point wax will be not easy to influence the rheological equationm of state.

In the present invention, can use various natural or synthetic waxs.These waxes can derive from animal, plant or mineral resources, as mentioned above, importantly the fusing point of wax about more than 130 °F in addition, wax do not have with inconsistent fragrance of chewing gum or structural property also be important.

Comparatively ideally be, the used wax of the present invention synthesizes, and preferably wax is molecular weight at 500～2000 ethene long-chain polymer.Here the compound of being mentioned is a Tissuemat E, is preferably fusing point at about Tissuemat E more than 155, and preferably fusing point is about 187 Tissuemat E.Other synthetic wax also can use as polyethylene glycol and halowax.

On the other hand, used wax can extract from oil.According to another preferred embodiment, use to have about 135 paraffin of fusing point, preferably the used melting point of paraffin wax of the present invention is about 180 °F, other wax that obtains from oil also can use, for example, have fusing point and be higher than 130 micro-crystallization wax, be suitable for very much the present invention.

The example that can be used in the native paraffin from the animal and plant resource of the present invention includes, but are not limited to beeswax, leaf wax, sugarcane wax, Brazil wax.As long as the wax of all these types has suitable fusing point to use.

The present invention comprises also and uses two or more wax simultaneously that the wax of for example two or more dissimilar or different stages can mix, to improve the character of wax integral body.Most typical is two kinds of waxes to be mixed to reach mix desired special fusing point.When two or more wax is mixed for when of the present invention, importantly the fusing point of mixture is higher than about 130 °F.

The present invention comprises that also employing is coated with the stain step more than one, so that can be coated on the particle more than the wax of one deck.Because wax is added under molten state, importantly the wax of first coating has the fusing point of the wax that is higher than second coating.In addition, wax being coated with stain also is desirable on the particle that was coated with by dissimilar coating materials in advance.Equally, wax is coated on the particle, is coated with the stain particle with the dissimilar stain materials that is coated with again subsequently.

In mixing drum, the wax that is added in the fusing in the powdered ingredient composition is preferably limited the quantity of, with produce humidity, dustless, do not flow, not moulding and frangible mixture." frangible " speech is meant that this moist mixture self is easily separated.By comparing, moist mixture should have wet husky viscosity and quality preferably.By contrast, moist mixture should not have too many wax preferably, and is doughy to make it to become; Starchy, claylike or the soup shape.Have been found that and just can't demonstrate advantages more of the present invention if this mixture becomes doughy state really.Particularly, doughy mixture is to be difficult to mix, processing and cooling.

The amount of the fusing wax of the mixture of this viscosity of required generation will be according to selected specific wax with the specific food ingredient that is coated with stain and different.Comparatively ideal is that the amount of the wax of fusing is about 10%～50%(wt) of a moist mixture.Be preferably at about 15%-45%(wt) between, preferably between about 25%～40%(wt).

Is the method preferably in the wax of the fusing adding powdered ingredient composition continuous the mixing, and a small amount of adding of the wax of fusing is also changed in time and increases.When adding the wax of fusing by this way, it is desirable to before the wax of next group fusing adds, mixture be mixed.Wax according to the fusing of this method preferably will be evenly distributed in the mixture, in mixture, do not produce cause big, as the wax layer of the fusing of the block of clay.

Can determine that by visual inspection the situation of its moist mixture decides the amount of the wax of suitable fusing.Above-mentioned characteristic is promptly dustless, mobile, frangible ratio is easier to observe, and different with flowability with the viscosity of dough/pasta shape.

Nature, the optimum weight proportioning of wax and food ingredient is in case determine that the consumption of optimum wax is also determined.

After the wax of a collection of fusing in the end is added into, with mixture particularly the wax of powdered ingredient composition and fusing should be evenly distributed in the mixture, the Best Times of mixing can be determined according to vision.

The hybrid mode that influences mixture be sure of to the present invention it is important.Particularly, be sure of that it is important that compression-type mixes for a wax of fusing and food ingredient particle extruding cluster group.This is diverse with having the high shear stress formula mixing that separates the moist mixture component.Therefore, mixer types is that planetary-type mixer or other can produce the blender of identical compression-type preferably.

In mixed process, preferably provide heat to mixing drum so that the wax of fusing remains on its fusing point continuously.Although mixture during mixing can allow the part cooling, when wax begins to solidify, the power of mixing will be needed naturally to increase.

After final the mixing, moist mixture will cool off and harden, and cooling is preferably finished by moist mixture is taken out from mixing drum and is layered on dish.Have been found that best paper gasket on dish so that the product of sclerosis takes out easily, in illustrated embodiments, moist mixture is layered in the dish, the degree of depth is greatly between 1～2 centimetre.

Comparatively ideal cooling is by finishing coiling in room temperature is placed down in the room one period sufficient time, wax being solidified fully.Certainly, the required time of cooling will be different according to the mixing temperature of specific wax and wax.Work as 15%(wt) paraffin use down at 180 °F, plate preferably at room temperature cooled off about 4～6 hours, with its mixture of abundant sclerosis.In addition, plate can be placed in the refrigerating chamber to reduce required cool time.

After the cooling, mixture generally preferably is shape and the big or small hard dry bulk that has nothing in common with each other.In this respect, the mixture of sclerosis is easy to handle, and forms required granular size.This can carry out in a different manner.Preferably the mixture of sclerosis is packed in the grinder, mixture is ground into smaller particles, miscellaneous equipment such as barreling also can be used to pulverize the mixture of cooling.Grinder and other device preferably are equipped with sieve and sift out required compound particles, if necessary, also can adopt other technology such as secondary to sift out, or can both be separated with maximum particle to guarantee minimum particle with cyclone separator.At present, use the sieve in 0.04 inch hole to produce the acesulfamek particle of waxing in the illustrated embodiments.

In most preferred embodiment, as long as control as maximum particle size.Be that smaller particles is not removed.Therefore, the product of waxing not only comprises bigger acesulfamek crystal bunch group, and comprises little not bonding crystal.It is desirable that this situation is considered to for food ingredient special in some chewing gum formulations.For example, in most preferred embodiment, think when chewing-gum chewing, to produce following effect, even some less and/or not bonding acesulfamek particle release must be faster than the acesulfamek that is bonded into bigger bunch by more wax.As a result, this release performance makes the consumer begin and can both enjoy sufficient sugariness subsequently.

In other some embodiment, can control minimum and maximum particle to produce granular size than close limit.Want to make all food ingredients to have the more uniform releasing properties that delays, adopt above-mentioned way optimal.And, can isolate various granular size, in chewing gum, carry out the predetermined mix of these particles then, so that obtain the sugariness release performance of stricter control.

After the shaping particles, just the powdered ingredient composition of foregoing description can be added in the chewing gum.The remainder of chewing gum food ingredient has no importance for the present invention.In other words, the batching particle of waxing can be added in the common chewing gum formulations by general fashion.Comparatively ideal chewing gum formulations is the acesulfamek sugar-containing chewing gum that comprises waxing.Yet, the acesulfamek of waxing or other high-potency sweetener can be used in contain sugar with the chewing gum of sugar-free in, to increase sugariness.The food ingredient of waxing can be used in the general chewing gum or bubble gum.
