The invention relates to a production process for confectionery, to a confectionery product produced according to the production process, to a product comprising a composition and a flour, to a hard candy with a diameter, whose length is a strictly monotonically decreasing function, to a use for producing confectionery, to a device for the production of hard candies, to a process in this device, and to a hard candy, obtainable by this process.
Confectionery is a widespread and generally popular luxury food. A manner of producing confectionery essentially known in the prior art comprises pouring a liquid confectionery precursor mass into a single- or multi-part mold. The confectionery which is produced in the prior art in this basic manner includes fat-containing confectionery and confectionery made of a sugar mass. A fat-containing confectionery for example is chocolate. The confectionery made of a sugar mass includes candies. Among candies, a distinction is made between hard candies and soft candies. The hard candies also include medicinally active candies such as cough sweets. If a hard candy is provided with a stick for holding, it is described as a lollipop. Soft candies are for example fruit gums, toffees and chews.
Pouring a confectionery precursor mass into a mold of metal, such as for example aluminum, is known in the prior art. In this, to demold the hardened mass which comprises the confectionery product, a knock-out tool pushes through a base of the metal mold. The knock-out tool demolds the confectionery product and in the process gives it an indentation (knock-out mark). This production process of the prior art involves at least the following disadvantages. The production process allows only rather simple confectionery shapes. Further, the candy is inevitably given the knock-out mark, which can be undesirable for the styling of the confectionery product. The metal molds used are rather heavy. Moreover, the metal molds used are rather costly to produce. Further, because of the knock-out tool, the molds used must be rather stable.
In DE 872 149 C, a production process for confectionery is described, in which a metal mold is provided with a rubber lining. During the filling of the mold with the confectionery precursor mass, this rubber lining is laid tightly onto the inside of the metal mold by suction and for the demolding the rubber lining is detached from the metal mold. This production process from the prior art involves at least the following disadvantages. The process contains rather many or fault-prone or both process steps. Possible faults here are for example selected from the group consisting of damage to the rubber lining, production of a confectionery product not shaped as desired and failure of the demolding or a combination of at least two thereof. Further, the process is rather laborious.
Also known in the prior art and likewise mentioned in DE 872 149 C, but also in DE 10 2007 031 747 A1, is pouring of the confectionery precursor mass into a mold of an elastic material, such as for example rubber. Here for demolding the candy, the mold is elastically deformed or everted or both. This process of the prior art involves at least the following disadvantages. The candy can easily be damaged during the demolding. A rather large number of rejects are produced in the process. The demolding does not take place uniformly reproducibly.
Some disadvantages of the aforesaid production process could be avoided in the prior art by using molds which contain dimensionally stable parts, an outer edge and a base, which are connected by elastic parts (DE 872 149 C). However, such molds with supporting structure are rather costly. Further, such molds limit the styling of the confectionery.
Also known in the prior art is the production of confectionery by pouring a confectionery precursor mass into a dimensionally stable plastic mold, for example of polycarbonate. With these molds, the demolding is impeded by adhesion of the candy to the mold. The process is therefore more suitable for fat-containing confectionery such as chocolate. In this, the confectionery product to be demolded is cooled to as low a temperature as possible (EP 0 589 820 A1). DE 10 2007 031 747 A1, for the utilization of inelastic plastic molds for molding hard candy masses, proposes wetting the inner surfaces of the molds with a release agent. The use of the release agent makes the production process more laborious or more costly or both. If in the process not all the inner surfaces of the mold are wetted with the release agent, the confectionery product cannot be demolded, or not simply or not without damaging the mold or the confectionery product. Further, only release agents approved as foods are possible. Even such release agents can be undesirable on the surface of the confectionery product. A release agent can impair the confectionery product's appearance or taste or both. Removal of the release agent from the confectionery product requires at least one further production step.
Also known in the prior art is the use of two half molds for the production of confectionery (DE 40 04 688 A1). In this, the confectionery precursor mass is poured into one of the half molds and the two half molds then joined together. In this process, depending on the material of the mold used, the disadvantages already mentioned above arise during demolding. Further, with the joining of the half molds, the process contains an additional process step. This can be fault-prone, or cause additional costs, or both. Further, the confectionery products produced usually have a seam or a burr or both at a point at which the half molds were joined together. Such elements affecting the styling of the confectionery product are fundamentally undesirable.
Specifically for the production of fruit gums, pouring of the fruit gum mass into a negative mold which is formed of a cornstarch powder is also known in the prior art. In this, the negative mold is pressed into the cornstarch powder by a punch as the positive mold. For this, the cornstarch powder is located in a powder tray. To demold the fruit gums, the powder tray is inverted. In this prior art process, the following disadvantages arise. The negative mold formed by the punch is not dimensionally stable. In particular, in the time between the stamping of the negative mold and the pouring of the fruit gum mass it can become altered or destroyed or both. Moreover, the demolding can fail. A proportion of the cornstarch powder forming the negative mold can remain adhering to the confectionary. If this proportion is too great, this can too strongly affect the appearance or taste of the fruit gum, or both.
In general, it is a purpose of the present invention at least partly to overcome a disadvantage which results from the prior art. A purpose of the invention is to provide a production process for a confectionery product in which a demolding is one selected from the group consisting of less fault-prone, facilitated, simplified, and better reproducible, or a combination of at least two thereof. A further purpose of the invention is to provide a production process for a confectionery product, wherein a negative mold in a powder is more dimensionally stable. Further, it is a purpose of the present invention, to provide a production process for a confectionery product, wherein the confectionery product is produced with the aid of a negative mold in a powder, wherein the powder can be reused as often as possible. Further, a purpose of the present invention, is to provide a production process for a confectionery product, wherein the confectionery product is produced with the aid of a negative mold in a powder, wherein as little as possible fresh powder is needed. A further purpose of the present invention is to provide an inexpensive production process for a confectionery product. Further, it is a purpose of the present invention to provide a production process for a confectionery product, wherein the confectionery product is produced with the aid of a negative mold in a powder, wherein during demolding as little powder as possible remains on the confectionery product. Further, it is a purpose of the present invention to provide a production process for a confectionery product, wherein the production process needs smaller storage capacity for molding tools. Further, it is a purpose of the present invention to provide a production process for a confectionery product, wherein the production process involves lower costs for molding tools. Further, it is a purpose of the present invention to provide a production process for a confectionery product, wherein the production process can easily or rapidly or both be changed over to production of a confectionery product of another shape. It is a purpose of the present invention to provide a confectionery product which contains none selected from the group consisting of a burr, a seam, a knock-out mark and a rim at least partly surrounding the confectionery product. It is a further purpose of the present invention to provide a confectionery product, wherein a design of a surface of the confectionery product can be executed as diversely as possible. Further, it is a purpose of the present invention to provide a hard candy which possesses at least one of the aforesaid advantages of a confectionery product. Further, it is a purpose of the invention to provide a hard candy comprising two or more layers. A further purpose of the invention is to provide two or multicolored hard candies. It is a purpose of the present invention to provide a multilayer hard candy containing one or more layers produced from a foam mass, or one or more layers produced from a fruit mass, or both. Further it is a purpose of the present invention, to provide a production process for a hard candy, which possesses at least one of the aforesaid advantages of a production process. In addition, it is a purpose of the invention to provide a production process for a hard candy, wherein the production process includes simultaneous pouring of two or more different hard candy precursor mass, preferably two or more different-colored hard candy precursor mass, into a mold.

During this, during each nth use a fraction of the reused powder is replaced by a fraction of powder not yet used for production of confectionery. Here n is a natural number which is greater than 1. A preferred n is selected such that once per day in an operating process a portion of the reused powder is replaced by a portion of powder not yet used for production of confectionery. If the procedure described, namely that in each nth confectionery production run only a part of the powder is replaced by unutilized powder, is repeated sufficiently often, then after a sufficiently high number of repetitions a static composition of the powder used in the subsequent confectionery production runs is established, wherein the static composition comprises approximately constant fractions of unutilized powder and of powder which has been used for a certain number of confectionery production runs.

The following measurement methods were used in the context of the invention. Unless otherwise stated, the measurements were performed at an ambient temperature of 25° C., an ambient atmospheric pressure of 100 kPa (0.986 atm) and a relative atmospheric humidity of 50%.
For measuring the Shore hardness, the method according to VDI/VDE 2616-Sheet 2 (2004-04): “Hardness Testing on Plastics and Rubber” was used.
The particle size distributions were measured with a HELOS laser refraction system (complies with ISO Standard 13320) from Sympatec GmbH System-Partikel-Technik, Clausthal-Zellerfeld, Germany. For this, the measurement range R3, the lens focal length f 100 mm and an xMb from 0.5/0.9 to 175.0 μm (the detected particle size range of a measurement ranges with statement of the first class—lower class limit/upper class limit—and upper limit of the coarsest class) was selected. As the dispersion system, the dry dispersion system RODOS/M from Sympatec GmbH System-Partikel-Technik, Clausthal-Zellerfeld, Germany was used. To minimize the sampling and sample splitting errors, the splitting of the material to be measured to the amounts required for the measurement was effected by means of a rotating riffle splitter. For each sample, 3 part samples were each measured once and the mean value for each sample, namely over the 3 part samples, calculated. The assessment of the measurement data was based on the Fraunhofer theory with the Sympatec assessment mode FREE (Version 5.8.2.0). According to the Fraunhofer theory, the refraction of light is assumed to be the predominant interaction between the particles and the laser light. Further parameters of the measurements are summarized in the list below.
For measuring the water content, the following instruments were used: a Sartorius MA 30 moisture analyzer (Sartorius AG, Gottingen, Germany), aluminum weighing pan and spoon. The moisture analyzer is not preheated before the measurement. If a measurement has already been performed with the moisture analyzer, the moisture analyzer is left cooling with open hood for at least 15 minutes prior to a further measurement. The moisture analyzer is switched on. The measurement parameters are 105° C. (drying temperature), Auto, 0-100%. The hood is opened and an aluminum pan put in. Zeroing is performed with the Enter key. A sample of mass 5.0 to 5.5 g is prepared. The aluminum pan is placed on a table and the sample uniformly distributed on the pan with the spoon. The pan is placed on the holder and the hood is closed. The moisture analyzer starts the measurement process automatically. When the moisture analyzer displays “END”, the measurement result is read off.

For degassing, the soft candy precursor mass was allowed to stand for 10 minutes. The soft candy precursor mass was now placed in a pouring bag. The pouring bag was used to fill the negative molds in the cornstarch flour created as described above with the soft candy mass by pouring. During the pouring, the soft candy precursor mass had a temperature of ca. 70° C. Filled negative molds were obtained. The soft candy precursor mass in the negative molds in the powder tray was matured in the drying room for 48 hours at a temperature of 30° C. and soft candies were thereby obtained. The powder tray was now inverted, so that the soft candies produced were demolded from the negative molds, and soft candies and cornstarch flour fell out of the powder tray onto a grating sieve. By shaking the grating sieve for 1 minute excess cornstarch flour was removed from the soft candies. Here the grating sieve was selected such that the soft candies remained on the grating sieve and the particles of the cornstarch flour fell through the grating sieve and could be collected thereunder in a container. In addition, the soft candies were blown clean with compressed air. Next, the soft candies were oiled in an oiling drum in order to avoid mutual adhesion of the soft candies and to impart a gloss to the soft candies. The oiled soft candies were now packed in a foil bag and then stored at 20° C. and an atmospheric humidity of less than 60%.
Example 5 relates to a further production according to the invention of a further soft candy according to the invention. Example 5 was performed identically to example 4, differing however in that another cornstarch flour was used as the molding powder. In example 5, a cornstarch flour which had a particle size distribution characterized by a D10 of 8.40 μm, a D16 of 9.72 μm, a D50 of 14.56 μm, a D84 of 21.12 μm, a D90 of 23.91 μm, a D95 of 28.3 μm, and by a Q10 of 17.56 vol. %, a Q20 of 80.21 vol. %, a Q40 of 99.72 vol. %, and a Q50 of 99.87 vol. % was used. Further, the cornstarch flour had a water content of 14.1 g/100 g based on the cornstarch flour.
Example 6 relates to a further production according to the invention of a further soft candy according to the invention. Example 6 was performed identically to example 4, differing however in that another cornstarch flour was used as the molding powder. In example 6, a cornstarch flour which had a particle size distribution characterized by a D10 of 8.40 μm, a D16 of 9.70 μm, a D50 of 14.52 μm, a D84 of 20.99 μm, a D90 of 23.86 μm, a D95 of 28.11 μm, and by a Q10 of 17.69 vol. %, a Q20 of 80.16 vol. %, a Q40 of 99.21 vol. %, and a Q50 of 99.88 vol. % was used. Further, the cornstarch flour had a water content of 6 g/100 g based on the cornstarch flour.
Comparative Example 1 relates to the production not according to the invention of a hard candy not according to the invention.
Firstly a formula for a hard candy precursor mass was prepared by weighing out the raw materials. The formula consisted of
After this, a batch boiler was used for the boiling. The batch boiler is a double-walled steam-heated stirred vessel with two-stage stirrer, vapor extraction, manhole as filling port, steam valve, temperature sensor, needle valve, pivotable vacuum and discharge vessel, venting or blow valve and pressure display. The sucrose and the water of the formula were fed into the batch boiler and the sucrose dissolved at 110° C. Then the glucose syrup was added and the resulting solution end-boiled in the batch boiler to 140 to 142° C., to reach a dry substance content of 96 wt. % of the mass obtained. The boiling time was about 8 minutes. The heating and boiling were effected with constant stirring with the two-stage stirrer. Thereby, the heat input into the solution or mass was assisted and all raw materials homogenously mixed. Through the needle valve, the finished boiled mass was discharged in a fan shape into the vacuum vessel. In the vacuum vessel, the mass was subjected to vacuum for 2.5 minutes at about 0.8 bar. The vacuum was broken by means of the venting valve and then the dye, the flavoring and the acid added according to the formula, and a hard candy precursor mass was thus obtained. The temperature of the mass during this was 115 to 120° C. with a dry substance content or 98 to 99 wt. %.
Next, the hard candy precursor mass was conditioned on a cooling table. The cooling table is a double-walled stainless steel table with water circulation. Before the hard candy precursor mass was placed on the cooling table, the stainless steel table plate was greased with a release wax. The hard candy precursor mass was placed on the stainless steel table plate and kneaded in order to distribute the dye, the flavoring and the acid homogeneously. During this, the precursor mass was folded several times until a temperature of ca. 80 to 85° C. was reached. During this, the temperature of the table was regulated so that no condensation water was formed.
For the subsequent demolding of the precursor mass, a tapered roller was used. The tapered roller is electrical and has 4 conical tapers and an adjustable height cone trough. The conditioned precursor mass was shaped into a strand by rotatory movements of the conical tapers. During this, the cone trough was raised or lowered in order to achieve continuous feeding of the strand to the tapered rollers. Before the use of the tapered rollers, these were preheated electrically. The strand obtained by the shaping had a temperature of 75 to 80° C.
Next the strand was narrowed in a strand former. For this, the strand former comprises 4 pairs of rollers and is heatable. By means of a continuously regulatable strand speed, continuous feeding of the strand was achieved.
The subsequent stamping of the hard candies was effected in an automatic stamping machine of the Strada type from Hansel Processing GmbH, Hannover, Germany. The narrowed sugar strand coming from the strand former was linearly introduced into the automatic stamping machine and divided into pieces. The hard candies thus obtained, after the stamping, fell onto a distributor belt. In order to avoid deformation of the stamped hard candies, these had to be cooled directly afterwards. This was performed on a cooling belt by means of air of temperature in the range from 16 to 18° C. and a humidity of ca. 40%.
Next, the cooled hard candies were individually packed in a wrapping machine of the type Miniwrap BVK 2000 A/B from Robert Bosch GmbH, Gerlingen-Schillerhohe, Germany After this, the individually packed hard candies were packed in portions in foil bags and stored at 18 to 20° C. and an atmospheric humidity of less than 60%.
Comparative Example 2 relates to the production not according to the invention of a soft candy not according to the invention. Comparative example 2 was performed identically to example 4, differing however in that another cornstarch flour was used as the molding powder. In Comparative example 2, a cornstarch flour which had a particle size distribution characterized by a D10 of 12.3 μm, a D50 of 18.2 μm, and a D90 of 29.7 μm was used. Further, the cornstarch flour had a water content of 13.2 g/100 g based on the cornstarch flour.
Table 1 below summarizes the results of examples 1 to 3 and of comparative example 1 on hard candies. It is clear that with the process according to the invention (examples 1 to 3) hard candies of a great variety of shapes can be manufactured. In particular, the hard candies can be provided with a great variety of reliefs and embossments. This is markedly limited or more complicated in the process not according to the invention according to comparative example 1 with an automatic stamping machine. Further, the hard candies of examples 1 to 3 are free from burrs and seams (clean shape). The hard candies according to comparative example 1 show markedly undesired traces of the production process such as for example a seam or an undesired edge in the hard candy.
Table 3 below summarizes the results of examples 4 to 6 and of comparative example 2 for soft candies. It is clear that the negative molds in the examples according to the invention are markedly more stable, i.e. less liable to destruction than is the case for the negative molds in comparative example 2 not according to the invention. Further, the soft candies in examples 4 to 6 can be demolded better than in comparative example 2, after the inversion of the powder tray, less cornstarch flour remains on the soft candies. As a result, the soft candies obtained according to the invention are also advantageous compared to those of comparative example 2 not according to the invention.
