Definitions
- the present invention relates to the technical area of the food industry and relates, in particular, to a process for the production of a packaged shelf-stable filled sponge-type bakery product.
- Packaged sweet sponge-type bakery products of the snack type with filling are known in the art. Usually these are made up of a baked mixture (or cake) of the sponge cake or brioche type associated with a hydrated filling cream for example vanilla- or cocoa-based, or a jam.
- This type of product has been very widespread commercially for years and is therefore available in a large variety of forms. It is, in fact, a practical and tasty solution for a snack between meals.
- it is a product of cylindrical shape in which sponge cake coated with a filling is rolled up on itself.
- the filling is placed between two layers of sponge cake (like a sandwich).
- the filling is located only inside the cake and is not visible from the outside.
- the production process of this latter type of product usually comprises the injection of a filling in a semi-finished product made of a traditionally baked mixture.
- the process consists of placing part of a mixture, for example for sponge cake, in a mould, placing the filling at the centre of the mould on top of the raw mixture and finally covering it all with additional sponge cake mixture.
- the preparation is then baked in a traditional oven for the time necessary for its baking.
- the bakery product with an injected filling in fact inevitably has a more or less evident hole on a surface, which, in addition to being aesthetically unappealing, can cause a possible leakage of the filling from the cake during processing and/or storage of the product.
- this type of product does not allow the injection of large quantities of filling and is subject to a certain unpredictability, and therefore variability, in terms of the distribution of the filling inside the product.
- This process has a further drawback given by the fact that the presence of a hydrated filling inside a snack mixture, following baking of the snack, leads to the formation, in the finished product, of concavities at the interface between cake and filling, and therefore a discontinuity of structure inside the product.
- the two components of the snack, the cake and the filling in fact, have different behaviours during the step of baking of the snack, and in particular, whereas the mixture increases in volume, the filling instead does not vary its volume. The result is therefore empty areas at the interface between the filling and the cake.
- the baking in a traditional oven of the aforesaid product inevitably causes, moreover, the formation of a crust and/or cracks on the surface of the product and at the same time gives rise to the migration of the humidity coming from a hydrated filling through the mixture, a phenomenon which continues also during the time of storage of the finished product.
- the result is thus a humidity gradient that crosses the thickness of the cake from the inside, which is moister, towards the outside of the finished snack, which is drier.
- Part of the filling consequently dehydrates, decreasing in volume in the formation of the aforementioned humidity gradient, leaving the finished product with less filling.
- the snack in addition to being aesthetically unappealing due to the cracks that form in the cake and possible darker colouring at the drier areas, is also a disadvantage from the organoleptic point of view. In this case, in fact, the snack may be too dry or even crispy outside.
- Patent application WO 2009/021553 describes a method for the production of a steamed cake doughnut-which has a total fats content comprised between 7 and 18%, which comprises the fact of making available a batter made of a powder mixture comprising wheat flour (30-50 wt %), a chemical leavening agent, sugar (22-32 wt %), egg yolk (3-10 wt %), emulsifiers, fats (8-16%) and optionally enzymes, milk proteins, salt, starch, hydrocolloids, dextrose and/or cocoa powder.
- the cake is steam baked at the temperature of about 100° C. for about 4-6 minutes.
- the presence of a hydrated filling is also foreseen, such as for example a cream, in the case of cakes without a hole, injected into the cake.
- JP 2007 306850 describes a western version of “dorayaki”, which comprises two layers of baked mixture, made of wheat flour, sugar, eggs, oils and fats, and a filling placed between the two layers.
- the baking is performed at a temperature of 200-300° C. for 20-30 seconds.
- FR 469 570 A discloses a filled “madeleine” and the process for the production thereof. This process comprises the formation of a base by pouring a batter for “madeleine” into a mold and subjecting it to a partial baking, sufficient to impart a relatively solid consistency to the base, so that a filling, e.g. jam, can be deposited thereon. Then additional batter is added to fill the mold, which is introduced into a conventional oven until complete baking.
- JP H01265851 discloses the preparation of a steamed sponge cake, whereby a dough is injected into a mould, pre-baked with steam, then a second dough is added to cover the pre-baked sponge cake, a filling is put in the center of the dough and it is steamed again.
- the technical problem of the present invention is therefore to make available a packaged shelf-stable bakery product of the type which has a casing of cake and a filling, wherein the casing has a sponge-type texture and a uniform appearance, free from cracks, crust, and uniform in colour, and wherein in the baked bakery product the content of filling is as high as possible.

- the above-mentioned different features of the first and second batter are such as to compensate the different baking treatments to which the two batters have to be subjected.
- the second batter is in fact subjected to a first and only baking, whereas the first semi-baked batter is subjected to a second and final baking. Thanks to said technique during the emulsification step, the baked and filled bakery product advantageously does not exhibit dishomogeneity in texture between the casing part that corresponds to the first batter and the casing part that corresponds to the second batter.
- Both of the above-mentioned parts are thus characterised by a sponge-type and soft texture, such as the sponge cake type, and a substantially homogeneous and uniform appearance, free of crust or cracks.
- the method of the present invention represents moreover the advantage of allowing the step of baking of the second mixture to be carried out in line with the overall production process, that is to say without the need to perform it in parallel. This translates into a more streamlined and therefore faster process with respect to the prior art. It also represents an advantage from the economic point of view because it allows to avoid wastage caused by the fact of having to cut out a pre-baked mixture, and because it allows the baking of the second mixture to be carried out in a single baking step.
- the process of the present invention allows the preparation of the product to be carried out in only two steps of baking, and at the same time to obtain, at the end of the second step of baking, an optimal baking of both layers.
- a method also falls within the scope of the present invention which consists in carrying out steps a) to i) described above, optionally with the inclusion of a step of surface decoration as described above between steps h) and i).
- step d) of the process of the present invention envisages the dosing of a filling inside the layer of semi-baked mixture of step c), placed in a baking mould which gives to the layer of semi-baked mixture a concave shape.
- This allows to include in the final bakery product a mugh higher quantity of filling than with the processes of the prior art, such as e.g. the process according to FR 469 570 A, which involves the deposition of a filling, such as jam, onto a susbtantially flat pastry base.
- the present invention also refers to the product obtained by means of the process of the present invention.
- the finished product has a shelf life of at least 3 months, more preferably 6 months.
- the fats content of the finished product is comprised between 8 and 16%, more preferably between 10 and 16%, even more preferably between 12 and 16%, most preferably it is 14% by weight based on the weight of the finished product.

Description
- This application is a Divisional of U.S. patent application Ser. No. 15/310,018, filed Nov. 9, 2016, which is a 371 of PCT/EP2015/056842, filed Mar. 30, 2015, which claims the benefit of European Patent Application No. 14425058.6, filed May 15, 2014. The contents of each of which are herein incorporated by reference.
- The present invention relates to the technical area of the food industry and relates, in particular, to a process for the production of a packaged shelf-stable filled sponge-type bakery product.
- Packaged sweet sponge-type bakery products of the snack type with filling are known in the art. Usually these are made up of a baked mixture (or cake) of the sponge cake or brioche type associated with a hydrated filling cream for example vanilla- or cocoa-based, or a jam.
- This type of product has been very widespread commercially for years and is therefore available in a large variety of forms. It is, in fact, a practical and tasty solution for a snack between meals. In some cases it is a product of cylindrical shape in which sponge cake coated with a filling is rolled up on itself. In other cases the filling is placed between two layers of sponge cake (like a sandwich). In still other cases the filling is located only inside the cake and is not visible from the outside.
- The production process of this latter type of product usually comprises the injection of a filling in a semi-finished product made of a traditionally baked mixture.
- Alternatively, the process consists of placing part of a mixture, for example for sponge cake, in a mould, placing the filling at the centre of the mould on top of the raw mixture and finally covering it all with additional sponge cake mixture. The preparation is then baked in a traditional oven for the time necessary for its baking.
- This solution, although more complex, can be preferable industrially, compared to the injection of the filling in a baked semi-finished product, since it allows to obtain a finished product of higher quality.
- The bakery product with an injected filling in fact inevitably has a more or less evident hole on a surface, which, in addition to being aesthetically unappealing, can cause a possible leakage of the filling from the cake during processing and/or storage of the product. Moreover this type of product does not allow the injection of large quantities of filling and is subject to a certain unpredictability, and therefore variability, in terms of the distribution of the filling inside the product.
- On the contrary, in the case of products in which the filling is placed during a processing step between two dosings of mixture, it is possible to obtain a reliable reproducibility of the characteristics of the finished product.
- However, also this latter type of product has drawbacks.
- With the process just described, in fact, it is not possible to include in the snack a high content of filling because the latter would tend, because of its considerable weight, to sink and seep into the thickness of the mixture underneath, with the risk of leakage from the base of the mixture while it is still raw.
- This process has a further drawback given by the fact that the presence of a hydrated filling inside a snack mixture, following baking of the snack, leads to the formation, in the finished product, of concavities at the interface between cake and filling, and therefore a discontinuity of structure inside the product. The two components of the snack, the cake and the filling, in fact, have different behaviours during the step of baking of the snack, and in particular, whereas the mixture increases in volume, the filling instead does not vary its volume. The result is therefore empty areas at the interface between the filling and the cake.
- The baking in a traditional oven of the aforesaid product inevitably causes, moreover, the formation of a crust and/or cracks on the surface of the product and at the same time gives rise to the migration of the humidity coming from a hydrated filling through the mixture, a phenomenon which continues also during the time of storage of the finished product. The result is thus a humidity gradient that crosses the thickness of the cake from the inside, which is moister, towards the outside of the finished snack, which is drier. Part of the filling consequently dehydrates, decreasing in volume in the formation of the aforementioned humidity gradient, leaving the finished product with less filling.
- This, in addition to being aesthetically unappealing due to the cracks that form in the cake and possible darker colouring at the drier areas, is also a disadvantage from the organoleptic point of view. In this case, in fact, the snack may be too dry or even crispy outside.
- In order to overcome the above disadvantages, instead, it is desirable from an industrial point of view to obtain a product in which the casing (cake, i.e. baked mixture) is soft, without a crust, and with humidity content which is homogeneous, just like, consequently, its appearance, and in which the content of filling is the highest possible.
- The need therefore arises to make available a packaged shelf-stable bakery product of the type which has a casing of cake and a filling, wherein the casing exhibits a sponge-type texture and a uniform appearance free from cracks and crust and uniform in colour, and wherein the baked bakery product exhibits at the same time a high content of filling.
- Patent application WO 2009/021553 (Puratos N.V.) describes a method for the production of a steamed cake doughnut-which has a total fats content comprised between 7 and 18%, which comprises the fact of making available a batter made of a powder mixture comprising wheat flour (30-50 wt %), a chemical leavening agent, sugar (22-32 wt %), egg yolk (3-10 wt %), emulsifiers, fats (8-16%) and optionally enzymes, milk proteins, salt, starch, hydrocolloids, dextrose and/or cocoa powder. The cake is steam baked at the temperature of about 100° C. for about 4-6 minutes. The presence of a hydrated filling is also foreseen, such as for example a cream, in the case of cakes without a hole, injected into the cake.
- JP 2007 306850 describes a western version of “dorayaki”, which comprises two layers of baked mixture, made of wheat flour, sugar, eggs, oils and fats, and a filling placed between the two layers. The baking is performed at a temperature of 200-300° C. for 20-30 seconds.
- FR 469 570 A discloses a filled “madeleine” and the process for the production thereof. This process comprises the formation of a base by pouring a batter for “madeleine” into a mold and subjecting it to a partial baking, sufficient to impart a relatively solid consistency to the base, so that a filling, e.g. jam, can be deposited thereon. Then additional batter is added to fill the mold, which is introduced into a conventional oven until complete baking.
- JP H01265851 discloses the preparation of a steamed sponge cake, whereby a dough is injected into a mould, pre-baked with steam, then a second dough is added to cover the pre-baked sponge cake, a filling is put in the center of the dough and it is steamed again.
- The technical problem of the present invention is therefore to make available a packaged shelf-stable bakery product of the type which has a casing of cake and a filling, wherein the casing has a sponge-type texture and a uniform appearance, free from cracks, crust, and uniform in colour, and wherein in the baked bakery product the content of filling is as high as possible.
- A further technical problem of the present invention is to make available an aforesaid bakery product that contains no artificial preservatives.

- Preferably, the step e) of mixing is performed for a duration of time comprised between 5 and 15 minutes, more preferably 12 minutes, until complete mixing.
- Preferably, the preparation of the second batter of step e) is carried out in a planetary mixer fitted with a wire whisk.
- Preferably in step f) of emulsification and dosing of the second batter, the emulsification is carried out by passing the batter in a turboemulsifier, thus obtaining for example a batter that has a flow rate measured by the Bostwick method for 30 seconds of 0 cm/30″.
- Preferably, the turboemulsifier is operated at a number of revolutions of the rotor per minute comprised between 150 and 250, more preferably 200, with incorporation of a percentage of air by volume based on the volume of the mixture between 25 and 50%, more preferably between 35 and 40%, even more preferably 38%.
- Preferably, in step f), the dosing of the second batter is carried out by means of a dispenser with rotary nozzle.
- Preferably, in step f), the dosing of the second batter forms on the open and filled semi-finished product a substantially flat surface that covers it completely.
- Preferably, the first batter of step a), the second batter of step e) and the filling of step d) are free from gluten, wherein said starch is deglutinated, preferably rice and corn, and said flour is gluten free, preferably rice flour.
- Preferably, the first batter of step a), the second batter of step e) and the filling of step d) do not contain artificial preservatives.
- Preferably, the step g) of baking of the second batter is performed in a steam oven with homogeneous atmosphere of saturated steam at ambient pressure.
- Preferably, the step g) of baking of the second batter is performed at a temperature comprised between 90 and 100° C. for a time comprised between 8 and 16 minutes, more preferably at a temperature of 98° C. for 12 minutes.
- Preferably, at the end of baking, the casing of cake has a humidity comprised between 20 and 30%, more preferably equal to about 28%.
- As explained above, in fact, the second mixture obtained in step f) is also hydrated during baking thanks to baking in a saturated steam oven.
- Preferably, at the end of the baking of step g), the casing of cake, formed from the first and from the second layer of mixture, has substantially homogeneous organoleptic, appearance and humidity and water activity characteristics.
- Preferably, the step h) of cooling is performed immediately after the exit from the oven and has a duration of 5-15 minutes, preferably about 7 minutes.
- The baked bakery product exiting from step g) of baking of the second mixture is removed from the mould preferably by means of a suction pad system.
- Preferably, the step h) of cooling is followed by a step of surface decoration of the baked product, more preferably carried out with dosing of an anhydrous filling according to techniques known in the field, followed optionally by a further cooling of 5-10 minutes.
- Preferably, step i) of packaging is performed in a filtered air chamber.
- In step i) the product is preferably packaged in a metallised barrier film.
- Preferably, in the finished product, the casing has homogeneous organoleptic and rheological properties over the whole product.
- For this purpose, the aforesaid layer of semi-baked mixture of step b), upon dosing, can be formed with different rheological properties compared to the second layer of mixture at dosing (step f)). In particular, the specific weight can be different between the two mixtures. This can be achieved with a different treatment in the steps of emulsification and dosing respectively b) of the first batter and f) of the second batter, which contemplates in the case of the first batter an increase in volume that is lower than that contemplated for the second batter. Preferably, the first batter has a higher specific weight compared to the second batter.
- The above-mentioned different features of the first and second batter are such as to compensate the different baking treatments to which the two batters have to be subjected. Following the step g) of baking of the semi-finished product, the second batter is in fact subjected to a first and only baking, whereas the first semi-baked batter is subjected to a second and final baking. Thanks to said technique during the emulsification step, the baked and filled bakery product advantageously does not exhibit dishomogeneity in texture between the casing part that corresponds to the first batter and the casing part that corresponds to the second batter.
- Both of the above-mentioned parts are thus characterised by a sponge-type and soft texture, such as the sponge cake type, and a substantially homogeneous and uniform appearance, free of crust or cracks.
- It is also to be noted that the fact of forming the closure of the open filled semi-finished product with a second layer of raw mixture, rather than pre-baked and cut, gives rise to a product which, after baking, exhibits a casing having a substantially one-piece structure, no point of joining being evident between the parts that correspond to the first and second layer of mixture. This is an advantage not only in terms of appearance but also in terms of quality of the finished product, since the baked and filled bakery product is not susceptible to leakage of the filling.
- With respect to the prior art in which the closure of the product is achieved by a layer of second pre-baked and cut mixture, the method of the present invention represents moreover the advantage of allowing the step of baking of the second mixture to be carried out in line with the overall production process, that is to say without the need to perform it in parallel. This translates into a more streamlined and therefore faster process with respect to the prior art. It also represents an advantage from the economic point of view because it allows to avoid wastage caused by the fact of having to cut out a pre-baked mixture, and because it allows the baking of the second mixture to be carried out in a single baking step.
- The process of the present invention allows the preparation of the product to be carried out in only two steps of baking, and at the same time to obtain, at the end of the second step of baking, an optimal baking of both layers.
- A method also falls within the scope of the present invention which consists in carrying out steps a) to i) described above, optionally with the inclusion of a step of surface decoration as described above between steps h) and i).
- As seen before, step d) of the process of the present invention envisages the dosing of a filling inside the layer of semi-baked mixture of step c), placed in a baking mould which gives to the layer of semi-baked mixture a concave shape. This allows to include in the final bakery product a mugh higher quantity of filling than with the processes of the prior art, such as e.g. the process according to FR 469 570 A, which involves the deposition of a filling, such as jam, onto a susbtantially flat pastry base.
- The present invention also refers to the product obtained by means of the process of the present invention.
- Advantageously, the finished product has a shelf life of at least 3 months, more preferably 6 months.
- Preferably, the fats content of the finished product is comprised between 8 and 16%, more preferably between 10 and 16%, even more preferably between 12 and 16%, most preferably it is 14% by weight based on the weight of the finished product.
- Preferably, in the finished product, the casing has a water activity value between 0.85 and 0.90, more preferably comprised between 0.86 and 0.89, even more preferably about 0.87; and the hydrated filling has a value of water activity comprised between 0.84 and 0.90, more preferably comprised between about 0.86 and 0.88, even more preferably about 0.87.
- Preferably, the cake casing of the baked bakery product of the present invention has a value of humidity comprised between 20 and 30, more preferably about 28.
- Preferably, the bakery product according to the invention does not contain artificial preservatives.
- Preferably, the bakery product according to the invention is gluten free.
- Advantageously, the bakery product of the present invention is free of crust.
- Steam baking allows in fact to obtain a cake characterised by the absence of a crust. The saturated steam, in fact, does not dry the surface of the mixture, unlike what would happen in a conventional oven, but on the contrary, as already explained above, it increases the humidity of the baked mixture with respect to the raw mixture.
- Moreover, preferably, the casing of the finished product has as a whole, namely both on the exposed surface and in its interior, a homogeneous colouring.
- It should be noted, moreover, that the average values of water activity and of humidity of the bakery product of the present invention are relatively low compared to similar products of the prior art, and such as to effectively contribute to the inhibition of bacterial proliferation and organoleptic deterioration for a long period of time.
- Moreover, thanks to the particular process of the invention, a considerable balancing is obtained of the humidity and of the water activity of the mixture and hydrated filling that lead to a reduced migration of water or even to an absence of such migration during storage, and therefore a prolonged duration in time of the optimal organoleptic characteristics of the product.
- For these reasons, the bakery product of the present invention does not require the presence of added artificial preservatives. The term “artificial preservatives” refers here in particular to food additives identified by codes from E200 to E299 defined by law at European level (Directive of the European Parliament and of the European Council 2003/114/EC of 22 Dec. 2003).
- Preferably, therefore, the bakery product of the present invention contains no added artificial preservatives. This represents an advantage with respect to the prior art because it results in a product that is perceived by the consumer as being healthier and more natural and genuine. In a preferred embodiment, the bakery product has a flat and circular base, with diameter of about 7-8 cm, and a height of approximately 2.5-3.5 cm at the point in which the height is greatest.
- In this embodiment, in fact, the first mixture of semispherical shape will constitute the upper surface of the final bakery product, while the second mixture will constitute the aforementioned flat and circular base.
