Description

CONFECTIONERY PRODUCT

FIELD OF THE INVENTION

The present invention relates to a confectionery product comprising a moulded filling and a moulded shell. In particular, the present invention relates to a process for the preparation such a confectionery product.

BACKGROUND OF THE INVENTION

Many chocolate articles are shaped as part of a moulding operation. This includes depositing liquid tempered chocolate masses into a mould, cooling and demoulding to impart a defined shape to the finished article. For demoulding to work efficiently the chocolate mass has to solidify and contract sufficiently to release from the mould cavity. For chocolate masses, this is aided to a large part by fat crystallization and to a lesser extent by thermal contraction.

Chocolate confectionery products often include fillings, which tend to have a softer texture than chocolate. These fillings also use fats that generally do not require tempering and are cheaper than cocoa butter. These fillings do not demould due to their crystallization and texture characteristics. To enable demoulding of filled confectionery articles, the filling is always in direct contact and surrounded by chocolate. This chocolate coating provides an additional level of protection to the more heat and compression sensitive filling throughout the supply chain and during consumption.

There are chocolate like compounds that are similar in taste and texture to chocolate, but do not meet chocolate regulatory requirements due to their composition. These are often based on cocoa butter equivalent or cocoa butter replacers. While being mouldable, they do not provide the same sensory experience of a soft filling.

In terms of visible fillings, there have been commercially available confectionery products where the back (or bottom) of the product which is not in contact with the mould is left uncovered, but this results in an undefined shape of the filling on the “wrong” side of the product. This leads to an inferior and incomplete visual experience. As the filling is not shaped by the mould it would not be considered a moulded confectionery filling. Such fillings are described as an embodiment of EP2804487.

Alternatively, it is possible to fill chocolate cavities after demoulding with fillings or inclusions on the top of the product. Nonetheless, this would require additional depositing and cooling steps after demoulding and before packing, which in most cases makes it cost prohibitive. In this case, the filling shape will be limited to the flow properties of the filling, depositing technique and subsequent handling, versus taking on the shape of the mould.

The combination of softer texture, poor contraction and demoulding requirements are challenging and there are no known examples of moulded visible soft fillings. The present invention provides a means of providing a product that contains the unique product features to achieve such confectionery products. This invention uses a combination of features to enable the demoulding of soft visible fillings within common cooling conditions and cycle times without significant equipment modifications on moulding plants that produce filled confectionery articles.

To summarise, the concept of visible moulded soft shelf stable fillings is new, particularly the filling formulation, order of dosing filling and chocolate into a mould, the combination of features to aid demoulding of soft fillings, as well as a means of protecting the filling in its exposed form.

Hence, this invention solves the following issues: poor contraction and demoulding of soft fillings, poor product presentation of open backed filled tablets, while providing defined moulded shapes to soft fillings, providing protection for soft visible fillings, avoiding significant equipment modification on moulding plants making filled confectionery products and developing shelf stable fat based visible fillings.

SUMMARY OF THE INVENTION

According to a first aspect of the invention, there is provided a process of preparing a confectionery product comprising a shell and a filling, wherein the filling is visible and the filling is moulded, the process comprising:

(a) depositing the filling in a mould;

(b) depositing the shell in the mould;

(c) optional further component addition and optional backing off depositing;

(d) cooling; and

(e) demoulding, wherein the filling and shell both have portions directly in contact with the mould until the demoulding step, wherein the filling mixture post-demoulding has a hardness of between 1.90 N and 20.0 N at 20°C. The invention further provides a confectionery product comprising a shell and a filling mixture, wherein the filling mixture is moulded and visible and filling mixture has a hardness of between 1.90 N and 20.0 N at 20°C.

DETAILED DESCRIPTION OF THE INVENTION

Definitions

As used herein, unless otherwise indicated, weights are given as a weight percent.

As used herein, unless otherwise indicated, the term “added sweetener” or “added sugar” have the standard meaning in the art and refers to a sweetener or sugar which is not inherently present in other ingredients. In line with the recognised meaning in the art, naturally occurring sugars are found in foods such as cocoa, fruit (fructose) and milk (lactose). An added sugar therefore refers to a sugar or sweeteners put in foods during preparation or processing.

For example, the US FDA has defined added sugars as: “sugars that are either added during the processing of foods, or are packaged as such”, and include sugars (free, mono and disaccharides), syrups, naturally occurring sugars that are isolated from a whole food and concentrated so that sugar is the primary component (e.g., fruit juice concentrates), and other caloric sweeteners.

As used herein, unless otherwise indicated, the term “added fat” refers to fat that is not inherently present in other ingredients, such as in the flavourings (e.g. cocoa powder contains fat).

As used herein, unless otherwise indicated, the term “added water” refers to water that is not inherently present in other ingredients.

Filling Mixture

According to any embodiment of the present invention, the filling mixture preferably comprises one or more added fats, one or more non-fat solids, and optionally one or more flavourings, colourants and/or emulsifiers. These components will be discussed below.

Irrespective of the filling mixture of the present invention being visible, preferably the term “filling” has the standard dictionary definition, i.e. any material used to fill something - in the case of the present invention, a space in the shell.

The filling mixture, preferably measured post-demoulding, preferably has a hardness of between 1.90 N and 20.0 N at 20°C, preferably between 1.95 N and 18. N, preferably between 1.95 N and 15.0 N, preferably between 1.95 N and 10.0 N, preferably between 2.0 N and 8.0 N and most preferably between 2.25 and 6.0 N. The hardness is measured using the method of the examples set out below. It is noted that a depth of 8mm is used in this method. In the interests of clarity, this does not mean that all filling mixtures of the present invention have to be at least 8mm deep. Rather, this means when assessing the hardness of a filling mixture it is carried out on a sample that is greater than 8mm deep.

The hardness of the filling mixture is predominantly controlled by the fat content and distribution of fats within the filling mixture at a specific temperature. These features are discussed in more detail below.

As mentioned above, thermal contraction of a filling may impact the demoulding. The filling mixtures within the scope of the present invention display contraction degrees that assist demoulding without impacting texture or appearance. The contraction degree is defined as the total contraction between the largest volume and the smallest volume (i.e. including any volume growth caused by crystallisation and the subsequent contraction) given as a percentage of the starting volume (typically the starting volume will be smaller than the largest volume owing to crystallisation growth but larger than the smallest volume owing to thermal contraction).

The filling mixture preferably has a contraction degree of at least 0.60% when measured using a Choco-analyser (Aasted), preferably using the method set out in the examples below. Preferably, the filling mixture has a contraction degree of at least 0.65%, more preferably at least 0.70%, more preferably at least 0.75 and most preferably at least 0.80%.

Preferably, the filling mixture has a contraction degree of less than or equal to 5.0%, preferably less than or equal to 3.0%, preferably less than or equal to 2.5%, or less than or equal to 2.0%, or less than or equal to 1.5% or less than or equal to 1.0%. The upper limit is far less important than the lower limit, which controls the quality of demoulding. However, in preferred embodiments, the contraction degree is from 0.60% to 5.0%, from 0.65% to 3.0%, from 0.65% to 2.0% or from 0.70% to 1.5%.

The filling preferably contains no added water. In a preferred embodiment, the filling mixture is substantially free of water. Preferably the filling mixture comprises less than 5 wt.% water, preferably less than 4 wt.% water, more preferably less than 3 wt.% water, particularly less than 2 wt.% water, and most particularly less than 1 wt.% water.

Fats and Added Fats

Within the context of the present invention the term "fat" as used herein denotes a hydrophobic material which is also edible. Thus, fats are edible material that are substantially immiscible with water and which may comprise one or more solid fat(s), liquid oil(s)/fat(s) and/or any suitable mixture(s) thereof. The term "solid fat" denotes edible fats that are solid at the stated temperature and the terms "oil" or "liquid oil/fat" (unless the context indicates otherwise) both denote edible oils that are liquid at the stated temperature. This is defined further below.

In an embodiment, the filling mixture has a total fat content of from 15 wt.% to 50 wt.%, preferably from 20 wt.% to 45 wt.%, and most preferably from 25 wt.% to 40 wt.%.

In one embodiment, the filling mixture comprises from 15 wt.% to 50 wt.%, preferably from 20 wt.% to 45 wt.%, most preferably from 25 wt.% to 40 wt.% of the one or more added fats. It will be appreciated that the total amount of fat in the filling mixture may not be identical to the total amount of added fat due to small amounts of fat being present in other optional components of the filling mixture, for example, chocolate.

The term “solid fat” has its standard definition, i.e. a fat that is solid, i.e. stable in shape, at room temperature.

The term “liquid fat” has its standard definition, i.e. a fat that is liquid, i.e. flows to take on the shape of its container, at room temperature (i.e. standard ambient temperature defined below).

In a preferred embodiment, the solid fat content (SFC) of the individual fats is measured using IIIPAC 2.150a or 2.150b at 20°C. The percentage is given as weight percentage of the measured fat content, i.e. for the filling mixture, not as a percentage of the whole filling mixture.

A liquid fat preferably has a solid fat content of less than 15% by weight, preferably less than 10% by weight, preferably less than 7.5% by weight, preferably less than 5% by weight, preferably less than 2.5% by weight and preferably less than 0.5% by weight, i.e. 0.0wt%, measured using IIIPAC 2.150a at 20°C. For example, between 0.0wt% and 15wt%.

In this regard, it is noted that solid fats within the meaning of the invention do not necessarily have an SFC of 100% measured using IIIPAC 2.150a or 2.150b at 20°C. Hence, there is a difference between the terms “solid fat content” and “solid fat”. The solid fat relates to the fat itself, which overall may be solid at room temperature, i.e. “solid fat content” (SFC) is a specific property measured according to the methods defined herein. When referring to the fats in isolation, the solid fat content relates to the content measured using IIIPAC 2.150a or 2.150b at 20°C. The solid fat content of the filling mixture is measured at different temperatures using the method set out below.

A solid fat within the meaning of the present invention preferably has an SFC content of between 17wt% and 100wt% or between 20wt% and 100wt% measured using IIIPAC 2.150a or 2.150b at 20°C, preferably greater than or equal to 25wt%, or greater than or equal to 30wt%. In a preferred embodiment, the solid fat within the meaning of the present invention preferably has an SFC content of less than or equal to 100wt%, less than or equal to 95wt%, less than or equal to 85wt% or less than or equal to 75wt% solid fat measured using IIIPAC 2.150a at 20°C.

In a preferred embodiment, the filling mixture comprises a fat with an SFC of between 20wt% and 85wt%, and preferably between 30wt% and 75wt% measured using IIIPAC 2.150a or 2.150b at 20°C.

In a preferred embodiment, the filling mixture comprises a fat with an SFC of between 18wt% and 80wt%, and preferably between 20wt% and 70wt% measured using IIIPAC 2.150a or 2.150b at 25°C.

In a preferred embodiment, the filling mixture comprises a fat with an SFC of between 10wt% and 60wt%, and preferably between 12wt% and 55wt% measured using IIIPAC 2.150a or 2.150b at 30°C.

In a preferred embodiment, the filling mixture comprises a fat with an SFC of between 18wt% and 80wt%, and preferably between 20wt% and 70wt% measured using IIIPAC 2.150a or 2.150b at 30°C.

SFCs measured using IIIPAC 2.150a or 2.150b may be found in the Handbook, Vegetable oils and fats, published by AAK AB, for example.

In respect of the choice of which IIIPAC method to use when assessing the SFC, we note that the person skilled in the art is aware of which method is applicable to which type of fat. In general, when a fat requires tempering, i.e. the fat composition is subjected to a thermal treatment, in particular to a cooling and heating programme which is adapted to the nature of the fat, so as to promote crystallisation of the fat in a stable crystalline form. In particular within the scope of the present invention, where the solid fat content is measured with IIIPAC method 2.150 a, the fat composition is not required to be subjected to a thermal treatment. IIIPAC method 2.150b requires the fat composition being subjected to the thermal treatment programme described in that method.

In an embodiment, the filling mixture of the present invention comprises a liquid fat.

In a preferred embodiment when a liquid fat is present in the filling mixture, the liquid fat is not the only added fat in the filling mixture. In a preferred embodiment, the liquid fat is present in combination with a solid fat as defined above. In an embodiment, the filling composition comprises a solid fat and a liquid fat, wherein the weight ratio of liquid fat to solid fat is at most 1.5: 1.0, preferably at most 1.4: 1.0, more preferably at most 1.2: 1.0, more preferably at most 1.1 : 1.0, and more preferably at most 1.0: 1.0. In an embodiment, the weight ratio of liquid fat to solid fat is at least 0.01 :1.0, at least 0.05:1.0, at least 0.10:1.0 or at least 0.20:1.0. Accordingly, in a preferred embodiment, the ratio of liquid fat to solid fat is between 1.5: 1.0 and 0.01 :1.0, preferably between 1.4: 1.0 and 0.05:1.0 and preferably between 1.2: 1.0 and 0.10:1.0. For certainty, in the above ratios, a value of 1.0: 1.0, for example, equates to a 50wt% combination each of liquid fat and solid fat.

The solid fat content of the filling mixture is measured using IIIPAC 2.150a, preferably by the method set out in the examples. It is noted that this is the method used in EP2804487, which is set out as a comparative example below.

In an embodiment, the filling mixture has a solid fat content of from 50% to 90%, preferably from 60% to 85%, preferably from 65% to 85%, and most preferably from 67.5% to 80%, at 0°C.

By controlling the solid fat content profile to match the above definitions it is possible to control the texture and the demoulding of the filling to ensure the appropriate consumer experience and manufacturing ease.

The fats that are preferably used to achieve the above fat distributions are discussed below.

The liquid fat optionally used for preparing the filling can be any vegetable oil or fat that is liquid or that can be liquefied at ambient conditions. The oil is suitably a food grade oil. Examples include sunflower oil, rapeseed oil, olive oil, soy oil, soy bean, fish oil, linseed oil, safflower oil, corn oil, algae oil, cottonseed oil, grape seed oil, flaxseed oil, rapeseed oil, primrose oil, linseed oil, avocado oil, a nut oil such as hazelnut oil, walnut oil, macadamia nut oil, or other nut oil, peanut oil, rice bran oil, sesame oil, or combinations thereof. The above oils may be optionally hydrogenated (partially or fully) and optionally inter-esterified.

Optionally, the oil can contain one or more liposoluble compounds; such as for example plant polyphenols, fatty acids, such as n-3 fatty acids, n-6 fatty acids, vitamins, aromas, flavours, antioxidants, other active ingredients. Preferred antioxidants include ascorbic acid, ascorbyl palmitate, citric acid, rosmarin extract, BHA (Butylated hydroxyanisole), BHT (Butylated hydroxytoluene), mixed tocopherol, and EDTA (Ethylenediaminetetraacetic acid).

Preferably, a vegetable oil is used, more preferably an oil with a low SFA content is chosen such as high oleic sunflower oil or high oleic rapeseed oil. The above liquid oils may have differing oleic acid contents. For example, sunflower oil may be (% by weight): Conventional oil or high linoleic acid: 14.0%<Oleic acid <43.1%, Mid Oleic: 43.1%<Oleic acid <71.8%, High oleic: 71.8%<Oleic acid <90.7%, Ultra/Very-high oleic, 90.7<oleic acid. For example, safflower oil: conventional oil: 8.4%<Oleic acid <21.3%; and High oleic: 70.0%<Oleic acid <83.7%. Additionally, high oleic acid variants of the following oils are available, soybean oil (70.0%<Oleic acid <90.0%), rapeseed oil (70.0%<Oleic acid <90.0%), olive oil (70.0%<Oleic acid <90.0%), canola (70.0%<Oleic acid <90.0%), and algae oil (80.0%<Oleic acid <95.0%).

In other embodiments, the liquid oil may be medium-chain triglycerides, preferably triglycerides where the fatty acids have an aliphatic tail of 6-12 carbon atoms. These oils may be obtained from coconut oil, palm kernel oil or milk.

The solid fats used in preparing the filling mixtures of the present invention may be selected from known confectionery fats, cocoa butter equivalents etc. that are known in the art. For examples, Chocofill™ NH18/SG from AAK, lllexao™ SC 70 from AAK, lllexao™ SC 30-69 from AAK, for example.

In a preferred embodiment, the solid fat is present in an amount of the filling mixture of from 15 wt.% to 50 wt.%, preferably from 20 wt.% to 45 wt.%, most preferably from 25 wt.% to 40 wt.% based on the weight of the filling mixture.

In an embodiment of the invention, the filling may contain other fats typically used in confectionery. For example, selected from the group comprising of milk fat, coconut oil, palm kernel oil, palm oil, cocoa butter, butter oil, lard, tallow, oil / fat fractions such as lauric, stearin or olein fractions, hydrogenated oils (partial and full hydrogenation, shea fat, cocoa butter extender fats (for example, approved fats: illipe, kokum gurgi, mango, sal), inter-esterified fats (could be any fats and oils and could be either chemical or enzymatic inter-esterification), and blend of at least two of the above. These fats, if present, are preferably used at 15wt% of the filling mixture, preferably less than 10wt% and preferably less than 5wt%.

Non-Fat Solids

In an embodiment of the invention, the filling mixture comprises: from 25 wt.% to 85 wt.% of one or more non-fat solids based on the total weight of the filling mixture, preferably 30 wt.% to 80 wt.%, most preferably 35 wt.% to 70 wt.%.

For instance, typical savoury filling compositions may further comprise supplementary ingredients such as salt, maltodextrin, skimmed milk powder, full cream milk powder (FCMP), whey powder, cheese powder, natural or synthetic flavours, natural or artificial colours, starch based fillers, emulsifiers such as lecithin, and other ingredients.

For instance, typical sweet filling compositions may further comprise supplementary ingredients such as solid fats, sugar, fat, skimmed milk powder, full cream milk powder, whey powder, fruit acids, cocoa powder, natural or synthetic flavors, natural or artificial colors, starch based fillers, emulsifiers such as lecithin, and other ingredients.

The filling mixture of the invention preferably comprises one or more added sweeteners and/or bulking agents. In one embodiment, the one or more added sweeteners comprise saccharides (preferably chosen from sucrose, glucose (dextrose monohydrate or anhydrous), galactose, lactose, maltose, fructose, corn syrup), and/or polyols (preferably chosen from sorbitol, mannitol, maltitol, isomalt, xylitol or erythritol).

In one embodiment, the one or more added sweeteners and/or bulking agents comprise mono, di-, or polysaccharides.

Confectionery Product

The present invention provides a confectionery product comprising a shell and a filling mixture, wherein the filling mixture is moulded and visible.

The term “visible” has its standard meaning, i.e. can be observed without any product modification.

The term “moulded” has its standard meaning, i.e. made or shaped in a mould. It is clear that this is a product feature that is inherently clear even though it is related to a process feature. It is immediately apparent if a composition has been moulded or has, for example, simply been deposited. In the interests of clarity, the mould and the shell are not the same, i.e. a separate component is required to manufacture the fillings of the present invention. The shape of the overall product is controlled by the mould. Hence, the shape of the final product is limited by the mould design. For example, the products of EP2804487 do not contain a moulded filling as the filling is simply deposited into the shell.

In a preferred embodiment, the shell and filling mixture are in contact in the range of less than 95% of the surface area of the filling mixture, preferably less than 80%, and more preferably less than 60%. In a preferred embodiment, the shell and the filling mixture are in contact in the range of greater than 5% of the surface area of the filling mixture, preferably greater than 10% and more preferably greater than 20%. Preferably, between 5% and 95%, 10% and 80% and 20% and 60%.

In a preferred embodiment, the top edge of the filling mixture and the shell are separated by a gap around the perimeter of the filling mixture. In a preferred aspect of this embodiment, by surrounding the filling with a shell, protection is provided from the bottom and sides but the visible aesthetic of the moulded filling is retained from the top. In a preferred embodiment, the top edge may be a termed an upper circumferential edge and the upper circumferential edge of the filling mixture is not in contact with the shell over a portion of at least 25% of the entire length of the circumferential edge of the filling mixture, preferably at least 40%, preferably at least 60% or at least 80% or 100%.

In a preferred embodiment, the weight ratio of the filling mixture to the shell is between 1 :99 and 99:1 , 5:95 and 95:5, 10:90 and 90:10, 20:80 and 80:20, and 30:70 and 70:30.

The nature of the material for the shell is not particularly limited other than it is a foodstuff material capable of being moulded. In a preferred embodiment, the shell comprises a fatbased confectionery (e.g. chocolate or compound) or a sugar-based confectionery.

The term "fat-based" confectionery substance is intended herein to mean compositions which comprise a continuous phase, or matrix, of fat. Such substances, in general, comprise fat in an amount of at least about 15% by weight. The substances processed in accordance with the present invention preferably contain at least about 20% by weight fat and may contain up to about 85% to 90% by weight fat, although higher amounts are not intended to be precluded. In general, shells prepared in accordance with the present invention will contain from about 25% to about 70% by weight fat and more usually, from about 30% to about 60% by weight fat.

The term "sugar-based" confectionery substance is intended herein to mean compositions which comprise a continuous phase, or matrix, of fat. Such substances, in general, comprise sugar in an amount of at least about 15% by weight. The substances processed in accordance with the present invention preferably contain at least about 20% by weight fat and may contain up to about 85% to 100% by weight sugar, although higher amounts are not intended to be precluded. In general, products prepared in accordance with the present invention will contain from about 25% to about 90% by weight fat and more usually, from about 50% to about 80% by weight fat.

In a preferred embodiment, the shell is a chocolate or chocolate-analogue, e.g. chocolate compound, shell. These terms are well known in the art but definitions are provided below.

The shell layer, preferably measured post-demoulding, preferably has a hardness of between 20 N and 75 N at 20°C, preferably between 22 N and 60 N, preferably between 22 N and 50 N, preferably between 22 N and 40 N, preferably between 23 N and 40 N and most preferably between 25 and 35 N. The hardness is measured using the method set out above and used in the examples section.

In an embodiment, compositions of the invention may usefully be chocolate products (as defined herein), more usefully be chocolate or a chocolate compound. Independent of any other legal definitions that may be used compositions of the invention that comprises a cocoa solids content of from 25% to 35% by weight together with a milk ingredient (such as milk powder) may be informally referred to herein as ‘milk chocolate’ (which term also encompasses other analogous chocolate products, with similar amounts of cocoa-solids or replacements therefor). Independent of any other legal definitions that may be used compositions of the invention that comprises a cocoa solids content of more than 35% by weight (up to 100% (i.e. pure cocoa solids) may be informally referred to herein as ‘dark chocolate’ (which term also encompasses other analogous chocolate products, with similar amounts of cocoa-solids or replacements therefor). The term ‘chocolate’ as used herein denotes any product (and/or component thereof if it would be a product) that meets a legal definition of chocolate in any jurisdiction and also include product (and/or component thereof) in which all or part of the cocoa butter (CB) is replaced by cocoa butter equivalents (CBE) and/or cocoa butter replacers (CBR).

The term ‘chocolate compound’ as used herein (unless the context clearly indicates otherwise) denotes chocolate- 1 ike analogues preferably characterized by presence of cocoa solids (which include cocoa liquor/mass, cocoa butter and cocoa powder) in any amount, notwithstanding that in some jurisdictions compound may be legally defined by the presence of a minimum amount of cocoa solids.

The term ‘chocolate product’ as used herein denote chocolate, compound and other related materials that comprise cocoa butter (CB), cocoa butter equivalents (CBE), cocoa butter replacers (CBR) and/or cocoa butter substitutes (CBS). Thus, chocolate product includes products that are based on chocolate and/or chocolate analogues, and thus for example may be based on dark, milk or white chocolate.

Unless the context clearly indicates, otherwise it will also be appreciated that in the present invention, any one chocolate product may be used to replace any other chocolate product and neither the term chocolate nor compound should be considered as limiting the scope of the invention to a specific type of chocolate product. Preferred chocolate product comprises chocolate and/or compound, more preferred chocolate product comprises chocolate, most preferred chocolate product comprises chocolate as legally defined in a major jurisdiction (such as Brazil, EU and/or US).

Preparation of Confectionery Product

The present invention provides a confectionery product comprising a shell and a filling mixture, wherein the filling mixture is visible and the filling mixture is moulded, the process comprising:

(a) depositing the filling mixture in a mould;

(b) depositing shell material in the mould, wherein the shell material at least partially covers the filling mixture;

(c) optional further component addition and optional backing off depositing;

(d) cooling; and

(e) demoulding, wherein the filling mixture and shell both have portions directly in contact with the mould until the demoulding step.

The process of preparing the filling mixture is not particularly limited; known processes for combining the ingredients recited above may be used. However, in an embodiment, the filling mixture preparation comprises a step of heating the initial filling mixture to a temperature of at least 35°C. Preferably the mixture is heated to a temperature of: from: 35°C to 80°C, from 40°C to 70°C, from 42°C to 65°C, from 42°C to 60°C, and most preferably about 45°C. The purpose of this heating and stirring stage is to ensure the substantially complete, or complete, melting of the fats in the filling mixture.

The process for preparing the filling mixture preferably comprises refining steps for ensuring an acceptable particle size. These refining steps are standard in the art.

The process for preparing the filling mixture preferably comprises a tempering step. The tempering may be carried out by processes and equipment well known in the art. In a preferred embodiment, the tempering is carried out to provide a temper index of between 3.5 and 6.5, preferably between 4.0 and 6.0 and most preferably between 4.5 and 5.5 as measured by a temper meter (e.g. a Sollich Tempermeter E6).

In preferred embodiments, the cooling step (d) is at a temperature of: from -5°C to 20°C, preferably from 0°C to 17°C, preferably from 0°C to 15°C and more preferably from 0°C to 12°C. In a particularly preferred embodiment, the mixture is cooled to a temperature of about 10°C.

In preferred embodiment, the cooling step (d) is carried out for a time period of from 10 minutes to 180 minutes, preferably from 15 minutes to 120 minutes, preferably from 15 minutes to 60 minutes and more preferably from 15 minutes to 60 minutes.

In a particularly preferred embodiment, the mixture is cooled to a temperature of from -5°C to 20°C for a time period of from 10 minutes to 180 minutes and more preferably from 0°C to 15°C from 15 minutes to 60 minutes.

Further Components and Backing Off

The shell of the products of the present invention may comprise addition of further components that are typical in the confectionery field. For example, the shell may contain fillings (e.g. fat- or water-based), chocolate, baked foodstuffs (e.g. wafers, biscuits etc), inclusions (e.g. fruits, nuts, rice puffs, etc.), sugar confectionery (e.g. gummies, sugar panned spheres, marshmallows etc.) and combinations thereof.

Similarly, the filling mixture of the products of the present invention may comprise addition of further components that are typical in the confectionery field. For example, the filling may comprise baked foodstuffs (e.g. wafers, biscuits etc), inclusions (e.g. fruits, nuts, rice puffs, etc.), sugar confectionery (e.g. gummies, sugar panned spheres, marshmallows etc.) and combinations thereof.

In preferred embodiments, the further components comprise a baked foodstuff. The baked foodstuff is typically sweet, although could comprise low quantities of sugar as discussed, herein, or in some instances, may be savoury. Preferred baked foodstuffs comprise baked grain foodstuffs which includes foodstuffs that comprise cereals and/or pulses. Baked cereal foodstuffs are more preferred, most preferably baked wheat foodstuffs such as wafer(s) and/or biscuit(s). In a particularly preferred embodiment, the baked foodstuffs are wafer sheets.

Wafers are baked products which are made from wafer batter and have crisp, brittle and fragile consistency. They are thin, with an overall thickness usually of: < 1 to 4 mm and typical product densities range from 0.1 to 0.3 g/cm³ The surfaces may be precisely formed, following the surface shape of the plates between which they were baked. They often carry a pattern on one surface or on both. Wafers may also be produced by extrusion. Two basic types of wafer are described by K.F. Tiefenbacher in "Encyclopaedia of Food Science, Food Technology and Nutrition p 417-420 - Academic Press Ltd London - 1993":

1) No- or low-sugar wafers. The finished biscuits contain from zero to a low percentage of sucrose or other sugars. Typical products are flat and hollow wafer sheets, moulded cones or fancy shapes.

2) High-sugar wafers. More than 10% of sucrose or other sugars are responsible for the plasticity of the freshly baked sheets. They can be formed into different shapes before sugar recrystallization occurs. Typical products are moulded and rolled sugar cones, rolled wafer sticks and deep-formed fancy shapes.

In a particularly preferred embodiment, the confectionery product comprises within the shell a filling layer sandwiched between two wafer layers.

In an embodiment, the shell is closed off with additional shell material (i.e. “backing off”). Such process steps are carried out using known processes.

Examples

The present invention will be further understood by the following examples. The examples are illustrative in nature and should not be understood to limit the subject matter of the present disclosure.

Filling Manufacturing

To make the filling, the ingredients were weighed out first. The fat was melted at 45°C and mixed with the oil (where present) and remaining solids (e.g. milk powders, sugar, cocoa powder, salt) to a fat level of 24.5% in an industrial mixer (Robot Coupe MP450 L). This premix was passed through a refiner (Buhler SDWC -300) to bring the particle size down to 125 pm (digital micrometre, Mitutoyo). This pre-mix was sent through a refiner for a second time (Buhler SDWC -300) to convert the mass into flake with a final particle size of 27 pm (digital micrometre, Mitutoyo). This flake was liquefied in an industrial mixer (Robot Coupe MP450 L) with the remaining balance of oil (where present), lecithin, flavour (where present), and colour (where present) before being sieved through a 2 mm mesh. Product Assembly

The moulds are conditioned in a heating cabinet to 29°C. The chocolate is tempered in a tempering unit (Selmi One) to a temper index of 5 ± 1 (Sollich Tempermeter E6), where the heating stage is set to 45°C and the cooling stage usually between 27°C and 29°C, chocolate dependent. The filling is tempered in a tempering unit (Selmi One) to a temper index of 5 ± 1 (Sollich Tempermeter E6), where the heating stage is set to 45°C and the cooling stage usually between 26 and 27°C, filling dependent. The two wafer layer wafer fingers are cut to size. Using a piping bag, the filling is deposited into the central section of the conditioned mould. The mould is then placed on a vibrating table for a short duration (< 5 seconds) to flatten the filling. Subsequently enough chocolate is deposited over the filling to fill the cavity halfway. The mould is then placed on a vibrating table for a longer duration (< 60 seconds) to flatten the chocolate and remove any air bubbles. A wafer finger is placed centrally into the chocolate filled cavity, and then covered with more chocolate. The mould is then placed on a vibrating table for a short duration (< 5 seconds) to flatten the chocolate, cover the wafer finger and remove any air bubbles. Excess chocolate is removed with a scraper. The mould is then cooled for 25 - 30 min at 10°C in a fridge (Weiss-Technik Environmental Chamber) and then demoulded by inverting the mould and twisting gently at ambient conditions of 20°C.

The mould prepared a moulded filling cuboid in shape of dimensions 6mm by 6mm by 60mm encased in a trapezoidal shell with the lower face of the cuboid in contact with the shell and a gap of 2mm between the shell and the upper perimeter of the moulded filling. All other faces of the cuboid filling are visible. The trapezoid is 19mm by 12 mm (height) by 73mm with sloped sides of approximately 12 degrees.

For measuring the SFC values and hardness values, the method described below were used.

For IUPAC, 2.150A, 80°C = 30 mins, 30°C = 10 mins, 0°C = 30 mins, Each Temperature = 30 mins then take a reading.

For IUPAC, 2.150B, the information was taken from the supplier’s product specification.

For Comparative Example 4, the information is taken from EP2804487.

For hardness, a Stable Micro Systems Ltd., P/2 2mm diameter cylinder was used. The samples were stored for 2 weeks at 16°C. At the testing temperatures the probe speed was 1 mm/s to a depth of 8mm.

The properties of the added fat used are shown below in Table 2. As above, solid fat content is measured according to the methods recited.

Accordingly, the method and formulations of the present invention provide a novel confectionery that has visible fillings with a texture significantly different from chocolate that are capable of being demoulded. The comparative examples do not offer the same combination of distinguished textures and ability to be demoulded.

Example 4 and Comparative Example 6

The following fillings and products were made according to the procedure of the previous examples. The properties of the added fat used are shown below in Table 2. As above, solid fat content is measured according to the methods recited.

Demoulding was assessed over time periods of 20, 30, 45 and 60 minutes at 10°C. Comparative Example 6 was inferior to the examples within the present invention over all demoulding assessments. The ease of demoulding improved over extended cooling times.

Measurement of Contraction: Example 5 and Comparative Example 7

The following fillings and products were made according to the procedure of the previous examples.

The contraction degree percentages of Example 1 and Comparative Example 7 were calculated using the ChocoAnalyser (Aasted) according to the following method. The empty measurement cup was preheated in the instrument to 28 °C, the same temperature as the filling sample to be tested. Upon reaching the required temperature, the measurement cup without the lid was placed on a scale with the required metal bead for contraction measurement placed in the recess in the centre of the cup. The combined weight was fared to reset the scale. The filling mixture (10.6 g) was added to the measurement cup ensuring no mixture entered the metal bead. This was the weight that was equivalent to 8ml of filling. The cup was tapped on a table surface to get the filling to spread. The lid was placed on the cup before placing the cup in the contraction meter, ensuring that the metal bead remained in the centre. The cover was closed, locked and the Standard Contraction test started.

It was found that Example 1 had a contraction degree percentage of 0.83% and demonstrated good release when demoulded. Comparative Example 7 had a contraction degree percentage of 0.18% and demonstrated very poor demoulding performed under the same conditions described above.
