DETAILED DESCRIPTION OF THE INVENTION

[0045] The present invention offers many benefits over the prior art as it relates to novel multi-layered jelly/chocolate confectionery products, and their novel manufacturing method, with the products exhibiting relatively strong inter-layer adherence and having a highly attractive, and striking, visual appearance. Notably, in the key embodiment of the invention, each layer of the layered composite is visible to a consumer, prior to initial consumption, allowing a variety of shapes, colors and finishes to be imparted to the confectionery product. In hand with that, the dual (jelly/chocolate) nature of the product provides appealing and unusual taste/textural mouth feel characteristics, and allows (for example) the fun of the well known Jelly Babies confectionery to be combined with the luxurious and enduring appeal of a chocolate product.

[0046] Hitherto, it has not proved possible to manufacture, to a sufficient degree of quality, and on a commercial scale, a jelly/chocolate layered confectionery product in which the bonding interface between the jelly and chocolate has sufficient strength so as not to break too easily, during transit, packing and the like. The present invention, in its various aspects, addresses this by carefully controlling the temperature (and hence state) of the jelly and chocolate components, as they are introduced to a support (such as a mold), in the early stages of the manufacturing process.

[0047] The precise composition of the jelly and chocolate layers is not critical to the performance of the invention, although it is important, for commercial and mouth feel reasons, to provide a jelly texture which complements the texture of the chocolate layer. In that light, and to achieve a soft melt in the mouth texture, the following recipe was employed:

TABLE-US-00001 Ingredients Proportion Glucose (high DE [dextrose equivalency[ 55-65% for viscosity and short soft final texture. Sugar 30% Gelatine (high Bloom for clarity) 4%-6% Malic acid (to provide gentle/long lasting As required acidity)/natural flavors/colors.

[0048] As regards the chocolate composition, the examples below include the use of both milk and white chocolate (white chocolate differing principally in that it lacks any cocoa solids), with generally standard chocolate formulations being employed, but with a slight increase (of 2.5%) in the amount of cocoa butter used, to reduce the viscosity and thus to eliminate/mitigate the effects of tailing, and so that the chocolate will self level after deposition. In order to mix the additional cocoa butter component, the chocolate blends were heated to 40 C., subsequently tempered (controlled cooling and agitation to ensure correct crystallisation of the cocoa butter and thus an acceptable finish and feel), prior to deposition (see below) at 30 C.

[0049] The preferred manner to impart shape to the confectionery product is the process of molding, involving mold trays (having mold cavities which contain formations corresponding to the desired outward appearance of a finished product) which are dusted with a thin layer of molding starch, with the molding starch having a moisture content of between 5% and 8%. Above that range, poor molding can result, with the attraction of foreign matter to the confectionery surface, whereas starch which is too dry can result in undesirable hardening or crusting, on the outer surface. In summary (noting that the starch molding process is well known, in its own right), the process involves the application of molten/substantially-molten product into the starched mold, allowing the product to cool, and then tilting/overturning the mold tray (itself housing a number of mold cavities) to release the cooled (and at least partially solidified) product from the mold. The use of molding in this particular process, however, offers a further advantage in that the resulting chocolate surface has a matt appearance, which is beneficial for unwrapped (e.g. bite-sized) products, where scuffing/in-package abrasion and agitation can be a concern.

[0050] Referring first to FIGS. 1 to 5, illustrating the manufacture of a starch molded layered confectionery product, a mold 10 having a cavity 11 is shown, with the cavity having a shaped surface 12 which is configured so as to impart an outward Jelly Baby appearance to a finished product. The mold 10 is one of several, contained within a molding tray (not shown) and each inner surface 12 is dusted with a fine layer (in conventional manner) of molding starch, of the type described generally above. A liquor dispenser, shown schematically at 13, has two nozzles 14 and 15 (although the two nozzles may be in a concentric arrangement similar to that employed in one-shot depositors), each connected to separate (not shown) holding tanks, containing, respectively, molten jelly liquor and molten chocolate, for sequential dispensing to the mold cavity 11. FIG. 1 illustrates, in schematic form, the introduction of a quantity of molten jelly to the cavity 11, resulting (see FIG. 2) in a partially-filled mold 10, having an upper layer 16 of non-solidified jelly exposed to the second nozzle 15. Molten milk chocolate is then dispensed, through nozzle 15, into the mold cavity 11, bringing the molten chocolate into contact with the (as yet unsolidified) jelly mass, resulting in the layered product shown generally at 17, in FIG. 3. The jelly and chocolate layers (14a and 15a) do not mix to any complete extent, but the non-solid state of each component, as they are brought together, appears to result in a degree of mixing/interpenetration of the layers, at the interface between them. The degree of mixing can be influenced by controlling the temperature of each component, and by the time delay between the jelly and subsequent chocolate deposits. Experimentation has found that a delay of between five seconds and one minute is suitable, as this allows the jelly layer to start to solidify, very slightly, to an extent which prevents true mixing of both layers, as the chocolate is deposited, but which also allows a degree of interpenetration to occur, near the interface. Subsequent to the chocolate layer being deposited, the combined product is allowed to cool to 20 C., with the layered product then being removed from the mold by a tilting or inversion process (in generally known manner), and a subsequent (also known) de-starching operation [employing, for example, a Winkler flat bed de-starcher] and a glazing operation, prior to packing. The finished product, shown in FIG. 4, has a chocolate base layer 15a and an upper (in use) jelly layer 14a, which has a shiny, glazed and thus highly-visually appealing appearance, allowing partial transmission of the chocolate color, below it.

[0051] FIG. 5 illustrates, in schematic form, a slight modification to the process and product of FIGS. 1 to 4, in which an intermediate layer 18, of white (free of cocoa solids) chocolate is employed. In order to arrive at the three-layer product of FIG. 5, the initial jelly deposition stage is unchanged, but the subsequent step involves the deposition of a relatively small amount of white chocolate, in place of the milk chocolate deposit, described above. The timings and temperatures are largely as detailed above, with application of the white chocolate layer being followed, again by a suitable time interval, by the application of a somewhat thicker layer of milk (or indeed dark) chocolate. This results in a three layer construction, and has unexpected (and significant) technical advantages, related to the temperatures employed and the cooling profile of the jelly layer. Specifically, given the relatively high temperatures involved in the handling of molten jelly, the subsequent application of a chocolate layer can result in detempering of that chocolate component, giving risein the case of milk or dark chocolateto an unsightly appearance of the layer in contact with the hot jelly. The use of a white chocolate component, as an intermediate layer, addresses this, as any detempering of a white chocolate component does not result in any visible discoloration, meaning that the insulated milk/dark chocolate layer (applied last but forming the base layer, in the resulting product) is not affected in this way. The relative thicknesses of the white and milk/dark chocolate layers can of course be varied, as required, although it has been found that a one millimeter thickness of white chocolate, and a five millimeter thickness for the milk/dark layer is especially suitable.

[0052] Referring now to FIGS. 6 to 9, there is shown an alternative process for the manufacture of a layered jelly/chocolate confectionery product, involving a moving starched belt 20, driven (in these examples) by a pair of wheels 21. Starched belts are known, in themselves, and thus it is not necessary to elaborate on those here. The belt 20, in these examples, moves from right to left (as shown by the arrow, on the left hand side of the belt), with the liquor dispenser 13 being disposed above the moving surface, such that molten jelly and chocolate can be dispensed, respectively, through nozzles 14 and 15, onto the belt below.

[0053] FIG. 7 shows a quantity of deposited jelly 14b in position on the belt, having been deposited upstream (i.e. to the right of FIG. 7) in readiness for a subsequent deposit of chocolate (through nozzle 15) onto it. The considerations (time and temperature) explained in relation to FIGS. 1 to 5 apply equally, here, in that it is necessary to ensure that a degree of mixing/penetration can occur, between the jelly and chocolate layers 14b/15b, so as to effect a satisfactory bond, upon cooling, between them. The effect of the belt process, of course, is to produce a relatively flat dual-layer configuration, in contrast to the molded product of FIGS. 1 to 5, but having largely similar color, texture and mouth feel characteristics.

[0054] Depending upon the state (i.e. degree of fluidity) of the chocolate, as it is applied to the warm, soft jelly layer below it, the interface between the two can either be generally flat (as shown in FIG. 8) or curved/shaped, as shown, for example, in FIG. 9. Whilst there are a number of potential ways to achieve the configuration of the product shown in FIG. 9, one manner is to press a near-solidified chocolate component, having a convex lower surface 22, into contact with the non-solidified upper surface of the jelly layer, with the heat of the jelly layer causing the exposed chocolate surface to melt, to some degree, allowing mixing/interpenetration of the two, whilst retaining the basic convex shape of the chocolate component.

[0055] Turing lastly to FIG. 10, this shows (in both perspective and plan views) a jelly/chocolate layered confectionery product in bar form, produced by sequential depositions of jelly into a suitably configured (multiple) mold, followed by the application of a larger quantity of chocolate, substantially in the manner described by reference to FIGS. 1 to 5. It will be appreciated, of course, that different colored jellies could be employed, on a given bar, and that the chocolate layer could be a dual layer, as described in relation to FIG. 5.

[0056] It will also be appreciated that the finished product, whether it be produced by a molding or belt process, could subsequently be coated, panned or enrobed with a further chocolate layer, in a generally conventional manner.
