Description

Chewing gum coated with candy has long been popular with young and old. The conventional candy toppings are based on sugar and are therefore not suitable for use with sugar-free chewing gum. Sugar-free chewing gum coatings based on xylitol are also known.

For various reasons, however, chewing gums containing xylitol are less in demand than expected in the marketplace.

Sorbitol, which has long been used as an emollient and sweetener, is also used as a sugar substitute in the manufacture of sugar-free candy coatings known for sugar-free chewing gum. Unfortunately, however, it has been found that if sorbitol is applied in an aqueous coating solution to chewing gum cores, the recrystallization of the sorbitol to a thin crystalline coating is absent. Furthermore, the chewing gum cores subjected to the coating with sorbitol stick to one another, so that undesirable lumps form.

As a result, there is currently a need in the market for a sugar-free one made on the basis of sorbitol Coating that preferably does not contain xylitol.

The invention is based on the object of creating a sugar-free coating for food, luxury and medicinal products, in particular for the coating of chewing gum, confectionery types and pharmaceuticals, such as pills, tablets and others Substances with solid form is suitable, as well as to provide a method for producing the coatings. This task is achieved by the invention.

The invention relates to what is characterized by the claims Object. The problems associated with coating with coatings containing sorbitol become

1 30064/0393

overcome by the invention. It becomes a uniform, sugar-free coating with good appearance and taste release, as well as having the bite and chew properties of a soft crystal.

The inventive method for producing the sugar-free coating on a substance to be coated with solid form (hereinafter referred to as substrate) comprises the following steps:

- The substrate is coated with an initial syrup coated containing a sweetener, such as sorbitol, and / or another sugar-free sweetener, e.g. mannitol or contains hydrogenated starch hydrolyzate, an adhesive or binding component and a film-forming component; - A dust mixture is applied to the substrate coated with the first coating syrup, which one or more sweeteners in powder form, for example those already used in the first coating syrup, and a moisture absorbing agent, an anti-sticking agent (hereinafter referred to as "antiadhesive agent") and a dispersant.

In a preferred embodiment of the invention can optionally a second coating syrup can be applied to the substrate to cover the already applied coating to smooth and shine, this second coating syrup generally having similar ingredients as the dust mixture contains, but which is dispersed in water are.

Before applying the second coating syrup, the Coating with the first coating syrup and repeatedly with the dust mixture until a coating is obtained of desired thickness and weight on the substrate.

In the method according to the invention, the first coating syrup is made - also called bulking syrup - from

130064/0393

an aqueous solution of

a) sweetener (or volumizer),
"b) adhesive or binding component and
c) film formers.

The sweetener (or bulking agent) a) can be present in an amount of about 3O to about 70 percent by weight, preferably about 4-0 to about 60 weight percent based on the weight of the first coating syrup; the binder

b) can be used in an amount of from about 10 to about 50 percent by weight be present, preferably from about 25 to about 40 weight percent based on the first coating syrup; and the film former c) can be present in an amount of about 10 to about 40 percent by weight, preferably about 25 to about 40 percent by weight based on the first coating syrup. The first coating syrup additionally contains water in an amount of about 20 to about 70%, preferably from about 25 to about 65%. The first coating syrup or bulk syrup has the function of moist base layer to which the subsequently applied dry sweetener or volumetric agent, in the dust mixture is present, may adhere or by which it is absorbed. This creates the desired coating.

Examples of sweeteners or volumizers that are suitable for use in the first coating syrup are in essentially all known sugar-free sweeteners, such as sugar alcohols, e.g. sorbitol, xylitol, mannitol and their mixtures, with sorbitol being preferred, as well as maltitol, isomaltitol, hydrogenated starch hydrolysates and various sorbitol-containing hydrogenated glucose syrups or powder, hydrogenated disaccharides, tri- to hexahydrated saccharides, hydrogenated higher polysaccharides and the modified starch hydrolysates.

For filling the hydrogenated glucose syrups and / or powder usual glucose reacted with acids and / or enzymes

130064/0393

syrups are catalytically hydrogenated until all glucose end groups of the saccharides become alcohols, i.e. dextrose to sorbitol. In the case of hydrogenated glucose syrups, the total solids content is 72 to 80%. These solids consist of about 4 to about 20% Sorbitol, about 20 to about 65% hydrogenated disaccharides (i.e. maltitol), about 15 to about 45% hydrogenated Tci- bis Miepfcasacchariden and from about 10 to about 35% hydrogenated higher saccharides (higher than hepta).

Others for use in the first coating syrup suitable sweeteners and fillers are the free acid of saccharin, sodium, calcium and ammonium saccharin, cyclamate salts, Dihydrochaltone, Glycyrrhizin, L-aspartyl-L-phenylalanine methyl ester as well as their mixtures.

Due to the adhesive or adhesive present in the first coating syrup. The sweetener adheres to the binding component coating substrate. Examples of suitable binders are gum arabic, xanthan gum, tragacanth resin, Tapioca dexfcrin and modified cornstarch, where Gum arabic is preferred.

Another important component of the first coating syrup is the film-forming agent (film former) that the Deposition of a substantially uniform layer of the sweetener on the substrate to be coated allows. Examples of suitable film formers include gelatine, methyl cellulose, hydroxypropyl cellulose, ethyl cellulose, Hydroxyethyl cellulose and / or carboxymethyl cellulose.

The dust mixture is composed of a dry powder mixture from a) sweetener (or volume image) that is similar (preferably the same) to that in the first coating syrup sweetener used is; b) moisture absorption component; c) anti-adhesion component (or filler) and

130064/0393

d) dispersants. Components b), c) and d) are used in a weight ratio to the sweetener a) of about 5 to about 30 b): 1, from about 2 to about 20c): 1, and from about 0 to about 5 d) '· 1, used. The sweetener is thus used a) in an amount of about 40 to about 90 percent by weight, preferably about 60 to about 85 percent by weight, based on the dust mixture; the moisture absorption component b) is used in an amount of about 5 to about 30 percent by weight, preferably about 8 to about 20 percent by weight, based on the dust mixture; the anti-adhesion component c) is used in an amount of about 2 to about 20 percent by weight, preferably about 5 to about 15 percent by weight, based on the dust mixture; and the dispersant d) is used in an amount of about 0 to about 5 percent by weight, preferably about 0.5 to about 4 percent by weight, based on the dust mixture.

The sweetener (or volumizer) present in the dust mix can be any of those used in the first coating syrup be the aforementioned sweeteners. However, sorbitol is preferred.

Suitable moisture absorption compounds are therefor Mannitol or dicalcium phosphate, with mannitol being preferred, especially when sorbitol is used as a sweetener.

Examples of the anti-adhesion compound used in the dust mixture, which can also serve as a filler include calcium carbonate, talc and magnesium trisilicate, calcium carbonate is preferred.

Examples of the dispersant used according to the invention include titanium dioxide, talc and others as above specified anti-adhesion compounds, titanium dioxide being preferred.

130064/03 9 3

In preferred embodiments of the present invention, the weight ratio of the solids present in the first coating syrup to the dust mixture is about 5: 1 to about 20: 1.

If the first coating syrup and the dust mixture are applied only once, this is generally not sufficient to form a coating of the desired thickness on the substrate.

As a result, it is usually necessary to apply a second, third or even more coats of the first coating syrup and applying the dust mixture to form coatings of the desired thickness and weight can be obtained. In each case, the applied layers of the first coating syrup are allowed to dry before further layers of the coating syrup are applied. For example, when coating chewing gum cores Coatings with the first coating syrup and with the dust mixture made until the average Weight of the pieces of chewing gum about 90% cLes desired coated weight is, for example, when the coating is about 35 percent by weight of the coated stick of chewing gum should be, so can have eight or nine coatings each the first coating syrup and the dust mixture to be required.

It goes without saying for the person skilled in the art that the number of coating processes required also differs from that in the first Coating syrup present solids content from which Amount of the dust mixture to be used and of. depends on the type of substrate to be coated.

After a sufficient amount of the coating has been applied to the substrates to be coated, the Coating smoothed by applying the second coating syrup (also called cover syrup) to the cores and otherwise can be finished. This second coating syrup

^L 130064/0393

contains a) sweetener (or volumizer), preferably in Form of an aqueous solution or syrup, b) moisture absorbent, c) anti-adhesion component (or filler) and d) dispersant (i.e. the components of the dust mixture), as well as e) hot water with a temperature from about 50 <T3 to about 75 ° C. Preferably they are Components a), b), c) and d) in the second coating syrup identical to components a), b), c) and d) of the dust mixture. The sweetener (or bulking agent) a) (in solid form) is in the second coating syrup in one Amount of from about 4-0 to about 80 percent by weight present, preferably from about 50 to about 75 percent by weight, based on on the second coating syrup. The moisture absorption component b) is used in an amount of about 0 to about 20 percent by weight, preferably about 5 to about 17 percent by weight based on the second coating syrup. The anti-adhesion component c) is used in an amount from about 0 to about 20 percent by weight, preferably about 4 to about 16 percent by weight, based on the second coating syrup. The dispersant d) is used in an amount of about 0 to about 8 percent by weight, preferably about 1 to about 5 percent by weight based on the second coating syrup. The second coating syrup additionally contains water in an amount of about 0 to about 25 percent by weight, preferably about 5 to about 20 percent by weight.

Flavors in liquid form can be added with the first and / or second coating syrup while spray dried flavors can be added along with the dust mixture. Preferably be Flavors added after the first coating with the first coating syrup and dust mixture.

If the substrate to be coated is chewing gum, the flavor of the chewing gum

130064/0393

add base material. The flavor in the chewing gum core is in an amount of about 0.5 to about 1.5 weight percent present, preferably about 0.7 to about 1.2 percent by weight, based on the chewing gum core. The flavor in the coating is in an amount of about 0.5 to about 5 percent by weight present, preferably from about 1.25 to about 4 percent by weight based on the coating. Such flavors can be oils obtained from plants, leaves, flowers or fruits. Specific examples of flavor oils of this type are citrus oils such as lemon oil, orange oil, lime oil, grapefruit oil, fruit essences such as Apple, pear, peach, strawberry, apricot, raspberry, Cherry, plum and pineapple essences, as well as the following essential oils: peppermint oil, spearmint oil, mixtures of these Peppermint oil and oil of spearmint, clove, laurel, Anise, eucalyptus, thyme, cedar leaf, cinnamon, nutmeg, salbai, bitter almond, cassia and wintergreen oil (methyl salicylate). Various synthetic flavors, such as mixed fruit flavors, can also be added to the gum base can be incorporated, with or without conventional preservatives. Suitable sweeteners contained in the chewing gum core and / or coating may be present, are natural or artificial sugar substitutes.

These synthetic sweeteners that may be used may be present in the chewing gum core in an amount from about 0.04 to about 2.0 weight percent, preferably about 0.4 to about 0.8 percent by weight based on the chewing gum. Specific examples of such a suitable synthetic Sweeteners are the free acids of saccharin, sodium, calcium or ammonium saccharin, cyclamate salts, dihydrochalcones, Glycyrrhizic acid and salts, L-aspartyl-L-phenylalanine methyl ester and their mixtures.
