The present invention relates to a confectionery product containing maltodextrin, and at least 93% w/w erythritol.
Recent developments in confectionery manufacture have been the replacement of part or all of the sugar by sugar alcohol (polyol) in the interest of providing a product having a reduced calorie content and a lower tendency to cause tooth decay. Among the polyols which have been proposed for the manufacture of confectionery are isomalt, maltitol, xylitol, erythritol and mixtures thereof.
EP 0 533 334 describes a process for the production of hard candy characterized in that the maltitol content of the sugar alcohol mixture is more than 77% but less than 86% by weight based on dry substance.
U.S. Pat. No. 4,971,798 describes a hard confection based upon hydrogenated isomaltulose (=isomalt).
U.S. Pat. No. 4,883,685 describes a hard candy which comprises erythritol and saccharides selected from among sugars and sugar alcohols other than erythritol as well as a process for producing the hard candy.
JP 3100186 describes an erythritol based candy which is further containing a hydrocolloid.
There is still a further need of having a confectionery product which is based upon polyols and is sugar free.

More specifically it relates to a hard candy comprising maltodextrin, 93-97% w/w erythritol, flavours, high-intensity sweeteners and/or colouring agents. The hard candy may further comprise crystallisation modifiers selected from a group consisting of microbial gums, agar agar, pectin, alginic acid, sodium alginate, beta-glucans, carrageenan, glucomannan, guar gum, gum ghatti, gum tragacanth, karaya gum, tara gum, fenugreek gum, locust bean gum, and mixtures of two or more thereof, preferably carrageenan, as well as edible acids and/or their corresponding salts.
Erythritol is a carbohydrate-based polyol (sugar alcohol), i.e. a tetriitol represented by the chemical formula C4H10O4 and which has an excellent appearance in the form of white crystals and it is similar to the appearance of granulated sugar, sucrose. It is highly soluble in water, non-digestive, providing zero calories and is non cariogenic.
Furthermore, the confectionery product of the current invention is comprising maltodextrin. Maltodextrin consists of D-glucose units predominantly linked with α(1→4) glycosidic bonds and is classified by DE (dextrose equivalent) between 3 to 20. Typically maltodextrin is composed of a mixture of chains that vary from three to twenty glucose units long and it is produced from starch by partial hydrolysis. Maltodextrin is present in an amount of from 2% to 7% by weight of the confectionery product, preferably from 2% to 6% by weight of the confectionery product. Maltodextrin is present in an amount of from from 2% to 5% by weight of the confectionery product preferably hard candy.
One or more crystallization modifiers are added and are selected from a group consisting of microbial gums, agar agar, pectin, alginic acid, sodium alginate, beta-glucans, carrageenan, glucomannan, guar gum, gum ghatti, gum tragacanth, karaya gum, tara gum, fenugreek gum, locust bean gum, and mixtures of two or more thereof, preferably carrageenan.
The term “microbial gums”, as used herein, is intended to mean all gum polysaccharides of microbial origin, i.e. from algae, bacteria or fungi. Examples thereof include, for example, gellan and xanthan gums that are both produced by bacteria. A preferred microbial gum for use herein is xanthan gum, a microbial desiccation resistant polymer prepared commercially by aerobic submerged fermentation.
Xanthan is an anionic polyelectrolyte with a β-(1,4)-D-glucopyranose glucan backbone having side chains of (3,1)-α-linked D-mannopyranose-(2,1)-β-D-glucuronic acid-(4,1)-β-D-mannopyranose on alternating residues.
The repeating unit of gellan is a tetrasaccharide which consists of two residues of D-glucose and one of each residues of L-rhamnose and D-glucuronic acid. The tetrasacharide repeat has the following structure:[D-Glc(β1→4)D-GlcA(β1→4)D-Glc(β1→4)L-Rha(α1→3)]n. As it is evident from the formula the tetrasacharide units are connected with each other using an (α1→3) glycosidic bond.
Agar agar is a plant-derived gum polysaccharide The gelling agent is an unbranched polysaccharide obtained from the cell walls of some species of red algae, primarily from the genera Gelidium and Gracilaria, or seaweed.
Another water-soluble dietary fiber is pectin, which is a heterogeneous group of acidic polysaccharides found in fruit and vegetables and mainly prepared from waste citrus peel and apple pomace. Pectin has a complex structure, wherein a large part of the structure consists of homopolymeric partially methylated poly-α-(1,4)-D-galacturonic acid residues with substantial hairy non-gelling areas of alternating α-(1,2)-L-rhamnosyl-α-(1,4)-D-galacturonosyl sections containing branch points with mostly neutral side chains (1 to 20 residues) of mainly L-arabinose and D-galactose. The properties of pectins depend on the degree of esterification, which is normally about 70%. The low-methoxy (LM) pectins are less than 40% esterified, while high-methoxy (HM) pectins are more than 43% esterified, usually 67%.
Alginic acid and sodium alginate are vegetable gums of linear polymers containing β-(1,4)-linked D-mannuronic acid and α-(1,4)-linked L-guluronic acid residues produced by seaweeds.
Beta-glucans which are defined to consist of linear unbranched polysaccharides of linked β-(1,3)-D-glucopyranose units in a random order. Beta-glucans occur, for example, in the bran of grains, such as barley, oats, rye and wheat.
Carrageenan is a generic term for polysaccharides prepared by alkaline extraction from red seaweed. Carrageenan includes linear polymers of about 25,000 galactose derivatives. The basic structure of carrageenan consists of alternating 3-linked β-D-galactopyranose and 4-linked α-D-galactopyranose units. There are three main classes of commercial carrageenan: the kappa, Iota and lambda carrageenan.
Glucomannan is mainly a straight-chain polymer, with a small amount of branching. The component sugars are β-(1→4)-linked D-mannose and D-glucose in a ratio of 1.6:1.[1] The degree of branching is about 8% through β-(1,6)-glucosyl linkages.
Guar gum, which is defined as a galactomannan consisting of a α-(1,4)-linked β-D-mannopyranose backbone with branch points from their 6-positions linked to α-D-galactose. It is non-ionic and typically made up of about 10,000 residues. Guar gum is highly water-soluble and, for example, more soluble than locust bean gum.
Gum ghatti is a natural gum obtained from Indian tree, Anogeissus latifolia.
Gum tragacanth is a viscous, odorless, tasteless, water-soluble mixture of polysaccharides obtained from sap which is drained from the root of several species of Middle Eastern legumes of the genus Astragalus, including A. adscendens, A. gummifer, and A. tragacanthus.
Karaya gum, is a vegetable gum produced as an exudate by trees of the genus Sterculia. It is an acid polysaccharide composed of the sugars galactose, rhamnose and galacturonic acid.
Tara gum, is a white or beige, nearly odorless powder that is produced by separating and grinding the endosperm of C. spinosa seeds. The major component of the gum is a galactomannan polymer similar to the main components of guar and locust bean gums.
Fenugreek gum, consists of D-mannopyranose and D-galactopyranose residues with a molar ratio of 1.2:1.0. The main chain of this galactomannan comprises β-(1,4)-linked D-mannopyranose residues, in which 83.3% of the main chain is substituted at C-6 with a single residue of α-(1,6)-D-galactopyranose. The galactomannan is made up of about 2,000 residues. Fenugreek gum (seed endosperm) contains 73.6% galactomannan.
Locust bean gum is a galactomannan similar to guar gum. It is polydisperse, non-ionic, and is made up of about 2,000 residues. Locust bean gum is less soluble and less viscous than guar gum and needs heating to dissolve but is soluble in hot water.

Analytical methods
Texture analysis was conducted on the Stable Microsystems equipment, TA-XT plus Texture Analyzer. The program setting was as follows:
Results:
Sample Preparation: All samples were allowed to equilibrate at controlled temperature of 20° C. and were then removed from the place of storage just prior to testing.
Test Set Up: The HDP/90 was secured onto the machine base. The probe was calibrated prior to testing the samples. The sample were placed on the blank plate of the HDP/90 and positioned centrally under the probe. The penetration test was commenced.
Two characteristics were tested on the texture analyzer; hardness and fracturability. Below are definitions from Texture Technology on hardness and fracturability.
Hardness is the peak force of the first compression of the candy. When the products fracture; the fracturability point occurs where the plot has its first significant peak (where the force falls off) during the probe's first compression of the product.
Hardness and fracturability are two completely different parameters that are not comparable with each other.
