TITLE OF THE INVENTION COATED CONFECTIONERY PRODUCTS

BACKGROUND

[0001] The present disclosure relates generally to confectionery products. More specifically, the present disclosure relates to polyol-based coatings for confectionery products including, for example, chewing gum products and candy and methods of preparing the coated confectionery products.

[0002] Confectionery products and chewing gum, for example, in pellet form, are frequently enclosed with a hard or soft coating. Coatings provide an opportunity for the manufacturer to vary product characteristics such as taste, appearance, structure and nutritional value. Coatings can be made from a variety of sugar and sugarless syrups. However, applying coatings to confectionery products can be problematic. For example, the coating syrups may comprise ingredients that crystallize very quickly thereby causing processing problems such as plugging of the coating syrup supply line or spray nozzles during the coating process.

SUMMARY OF THE INVENTION

[0003] The present disclosure is directed to coated confectionery products and methods of making the coated confectionery products. In a general embodiment, the present disclosure provides a confectionery product comprising a confectionery center, and a coating comprising erythritol and an anti-crystallizing (e.g. crystallizing inhibiting) agent surrounding the confectionery center. For example, the anti-crystallizing agent mitigates or moderates the crystallization of erythritol so that it can be utilized more readily in confectionery coating processes.

[0004] In an embodiment, the weight ratio of the erythritol to the anti-crystallizing agent in the coating is between about 20:80 and about 80:20.

[0005] In an embodiment, the weight ratio of the erythritol to the anti-crystallizing agent in the coating is between about 40:60 and about 60:40.

[0027] Additional features and advantages are described herein, and will be apparent from, the following Detailed Description.

DETAILED DESCRIPTION

[0028] The present disclosure relates to coated confectionery products and methods of preparing such coated confectionery products. Generally, the coatings of the present disclosure comprise erythritol. The erythritol coatings can be non-cariogenic and tooth- friendly. The erythritol coatings can be low in calories and provide a reduced laxative effective. The coatings of the present disclosure can be used on any suitable confectionery products such as, for example, soft and hard candies and chewing gums.

[0029] Coating syrups may comprises ingredients such as, for example, certain polyols that tend to crystallize very quickly. In particular, erythritol crystallizes at a fast rate. For example, coating confectionery products with syrups comprising erythritol leads to frequent clogging of the syrup spray nozzles and the syrup transportation supply lines that feed into the spray nozzles. This reduces the efficiency and increases the costs of the coating processes using erythritol-based syrups due to the need for repeated cleaning and/or unclogging of the coating equipment.

[0030] Applicants having surprisingly discovered that the use of anti-crystallization agents mitigates the crystallization of erythritol-based coating syrups thereby leading to reduced clogging of the nozzles and the supply lines. At the same time, the final erythritol

coatings of the present disclosure have sufficient hardness and are similar in crunch and appearance to other polyol coatings.

[0031] In a general embodiment, the present disclosure provides a confectionery product comprising a confectionery center, and a coating comprising erythritol and one or more anti-crystallizing (e.g. crystallizing inhibiting) agents surrounding the confectionery center. The coating can partially, substantially or entirely surround the confectionery center.

[0032] The anti-crystallizing agent can be any suitable ingredient that mitigates or slows down erythritol crystal formation. For example, the anti-crystallizing agent can be hydroxypropyl methyl cellulose, gum tahla (i.e. gum arabic) or combinations thereof. The anti-crystallizing agent can also be polydextrose, inulin, fructooligosaccharide, carboxymethyl cellulose, microcrystalline cellulose, hydrolyzed guar gum, pyrolized dextrins (e.g. indigestible dextrins) or combinations thereof.

[0033] Pyrolized or indigestible dextrins are modified maltodextrins with very low reducing sugar content. Varieties are sold under the trade names of FIBERSOL® and NUTRIOSE®. FIBERSOL® is marketed by Fibersol America, a division of Matsutani Chemical Industry Co., Ltd of Hyogo-Pref, Japan. NUTRIOSE® is marketed by Roquette Freres of Lestrem, France.

[0034] In another embodiment, the anti-crystallizing agent can be a polyol such as maltitol. The anti-crystallizing agent can also be a polyol such as xylitol, sorbitol, mannitol, isomalt, lactitol or combinations thereof. It should be appreciated that the polyols can be in any suitable form such as, for example, powders or syrups.

[0035] In an embodiment, the weight ratio of the erythritol to the one or more anti- crystallizing agents in the coating is between about 20:80 and about 80:20. In another embodiment, the weight ratio of the erythritol to the one or more anti-crystallizing agents in the coating is between about 40:60 and about 60:40. In an alternative embodiment, the weight ratio of the erythritol to the one or more anti-crystallizing agents in the coating is approximately 50:50.

[0036] The coatings of the present disclosure can be used to coat any suitable confectionery centers. For example, the confectionery center can comprise jelly candies, pressed tablets, mints, chewy candies, hard boiled candies, chocolates, nougats, licorice, taffy, gels, solid foam, crystallized pastes, rework or combinations thereof. The confectionery center can also comprise a chewing gum in a form such as, for example, pellets, sticks, tabs, dragees, chicklets, batons or combinations thereof.

[0037] The coating can initially be present as a liquid syrup which contains from about 30% to about 80% or 85% of the suitable coating ingredients, and from about 15% or 20% to about 70% of a solvent such as water. The erythritol-based coating syrups of the present disclosure may include non-polyol ingredients which are commonly used in sugar and sugarless coatings. The specific ingredients and their usage levels will vary greatly according to the intentions for the formulation.

[0038] The use of one or more fillers (e.g., titanium dioxide, calcium carbonate, silicon dioxide) in the present disclosure may be advantageous. In this regard, these inorganic materials aid the coating process by giving the polyol-based syrup coatings a smoother finish. Furthermore, these inorganic fillers enhanced the ease with which polyols could be used, and in many instances substantially increase the crunchiness of the product.

[0039] In another embodiment, the present disclosure provides a method of making a confectionery product. The method comprises providing a confectionery center, and coating the confectionery center with a layer of a coating syrup comprising erythritol and an anti- crystallizing agent. Generally, such coating layers can be applied by, for example, spraying the coating syrups onto the confectionery centers. Spraying can be alternately started and stopped to allow layers of coating to dry onto the surface of the pieces. Forced air and dry powder additionally may be used to speed the drying process. The various parameters of the operation (spray time, dry time, air temperature, tumbling speed and others) will vary greatly from one system to another and may well vary within a coating batch and from batch to batch. They will be set based on the skill and experience of the developer and operator. Typical coating equipment usable in the present disclosure will include any suitable apparatus normally used for this purpose.

[0040] The syrup can be added to the confectionery centers at a temperature of from about 100° F to about 240° F. Preferably, the syrup temperature is from about 140° F to about 200° F. Most preferably, the syrup temperature should be kept constant throughout the process. In another embodiment, the syrup can be maintained at a temperature that will not melt the confectionery centers while the confectionery centers are being coated. The syrup may be mixed with, sprayed upon, poured over, or added to the confectionery center in any way known to those skilled in the art.

[0041] In some instances, a soft coating is formed by adding a dry charge or powder coating after a liquid coating. The dry charge may comprise natural carbohydrate gum hydrolysates, maltodextrin, gelatin, cellulose derivatives, starches, modified starches, sugars,

sugar alcohols (i.e. polyols), natural carbohydrate gums and fillers like talc and calcium carbonate.

[0042] Each component of the coating on the confectionery center may be applied in a single layer or in a plurality of layers. In general, a plurality of layers is obtained by applying single coats, allowing the layers to dry, and then repeating the process. The amount of solids added by each coating step depends chiefly on the concentration of the coating syrup. Any number of coats may be applied to the confectionery centers. Preferably, no more than about 75 coats are applied to the confectionery centers. More preferably, less than about 60 coats are applied and most preferably, about 30 to 60 coats are applied. In any event, the present disclosure contemplates applying an amount of syrup sufficient to yield a coated confectionery product containing about 10% to about 65% coating by weight of the total confectionery product. In an embodiment, the final confectionery product will comprise at least 30% coating by weight of the total confectionery product.

[0043] In another embodiment, once a coating of syrup is applied to the confectionery center, drying is performed on the wet syrup in an inert medium. A preferred drying medium comprises air. Preferably, drying air contacts the wet syrup coating in a temperature range of from about 70 ⁰ F to about 110 ⁰ F. More preferably, the drying air is in the temperature range of from about 80 ⁰ F to about 100 ⁰ F. The disclosure also contemplates that the drying air can possess a relative humidity of less than about 15 percent. Preferably, the relative humidity of the drying air used between syrup applications is less than about 8 percent.

[0044] The drying air may be passed over and admixed with the syrup coated confectionery centers in any way commonly known in the art. Preferably, the drying air is blown over and around the syrup coated confectionery centers at a flow rate, for large scale operations, of about 2800 cubic feet per minute. If lower quantities of material are being processed, or if smaller equipment is used, lower flow rates would be used. If a flavor is applied after a syrup coating has been dried, the present disclosure contemplates drying the flavor with or without the use of a drying medium.

[0045] In addition to the coatings of the present disclosure applied by spraying, optionally, flavors may be separately sprayed onto the pieces during the coating process to provide a flavored coating. If used, this flavor may constitute from about 0.01 to 3% of the total coating with levels of 0.5 to 2% being preferred. Flavors may be added before, during and after applying the syrup to the confectionery center.

[0046] Optionally, a final polishing coat may be applied to the pieces after the coatings have been applied. The polishing coat may use a wax, such as carnauba wax, or

shellac. It may also include fillers such as talc and colors. The polishing coat can be typically 0.1 to 0.5% by weight of the total coating.

Confectionery and Coating Ingredients

[0047] It should be appreciated that one or more ingredients such malted products, flavors, sensates, colors (e.g. azo free colors), sweetener, acids, actives and medicaments (e.g. listed below) can go into the coatings or the confectionery centers of the present disclosure. The ingredients can be added in a free form. The ingredients can also be part of an encapsulation, compaction, granulation and agglomeration to provide, for example, protected and longer-lasting ingredient components such as flavors and sensates. It should also be appreciated that any or all of the layers (e.g. coatings, confectionery centers) can comprise any suitable number, amounts and combinations of the malted products, flavors, sweeteners (including high intensity), sensates, acids, actives and/or medicaments.

[0048] Sugar sweeteners generally may include saccharide-containing components commonly known in the confectionery art, including, but not limited to, sucrose, dextrose, maltose, dried invert sugar, fructose, levulose, tagatose, galactose, corn syrup solids, and the like, alone or in combination. Alternatively, sweeteners may include glycerin, fruit concentrates and fruit pastes.

[0049] Maltitol may be used as a sugarless sweetener. Additionally, sugarless sweeteners may include, but are not limited to, other sugar alcohols such as xylitol, sorbitol, erythritol, mannitol, isomalt, lactitol, hydrogenated starch hydrolysates, and the like, alone or in combination.

[0054] It is understood that these flavorants may be used alone or in combination with or without a sensate such as, for example, a cooling or heating agent as is commonly known in the art. The flavorant or flavor may be encapsulated or non-encapsulated. Encapsulated flavorant may be used to increase or decrease the flavor release rate as is commonly known in the art.

[0055] Generally, sensates may be any compounds cause a cooling, heating, warming, tingling or numbing, for example, to the mouth or skin. Non-limiting examples of coolants include menthol substituted p-menthane carboxamides, acyclic carboxamides, menthone glycerol ketals, menthyl lactate, menthyl succinate, 3-l-menthoxypropane-l,2 diol, and spearmint.

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 include caprenin, glycerin, lecithin and combinations thereof. Aqueous sweetener solutions such as those containing sorbitol, hydrogenated starch hydrolysates, corn syrup, other polyols or sugars, such as tagatose, and combinations thereof, may also be used as softeners and binding agents in chewing gum.

[0074] A variety of processes for manufacturing chewing gum center are possible as is known in the art. For example, 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 desired form, such as by rolling into sheets and cutting into sticks, extruding into chunks, or casting into pellets.

[0075] 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, along with syrup and a portion of the bulking agent. Further portions of the bulking agent may then be added to the mixer. A flavoring agent is typically added with the final portion of the bulking agent. The entire mixing procedure typically takes from five to fifteen minutes, but longer mixing times may sometimes be required. Those skilled in the art will recognize that many variations of the above described procedures may be followed.

[0081] Coated chewing gum pellets having coatings comprising a polyol ratio of: 1) 60/40 erythritol/maltitol, and 2) 50/50 erythritol/maltitol were compared to a control maltitol coated chewing gum pellet comprising 100% maltitol as the polyol ingredient. The 60/40 erythritol/maltitol coated formula was most similar to the 100% maltitol coated control pellet for crunchy texture and cooling action. The control coating and the 60/40 erythritol/maltitol coating formula elicited cooling action in the mouth (peak moderate to high), nose (peak moderate), and throat (peak moderate). Cooling levels were slightly lower for the 50/50 erythritol/maltitol formula. Sweetness levels were similar across the 3 samples.
