The present invention further relates to a conched confectionery product and a method for preparing a conched confectionery product.
Cocoa flavor is the basis for ample food products such as confectionery products and beverages. In 2019, 5.5 million tons of cocoa beans have been harvested worldwide. However, the area where cocoa can be harvested is limited. Furthermore, obtaining the final raw product which can be used for example in the manufacturing of chocolate requires multiple processing steps including harvesting, sorting, fermenting, and drying as well as the shipping costs. This makes cocoa a rather expensive raw material.
In addition, cocoa pricing can be highly volatile, and the industry can experience tight supplies as emerging markets are increasing their consumption of chocolate and cocoa-based products.
Furthermore, the cultivation and production of cocoa bring about numerous negative environmental impacts in order to meet the high worldwide demand, such as extensive greenhouse gas emissions, e.g. due to deforestation and land-use change, a high water footprint, the use of large amounts of herbicides and pesticides, as well as its shipment to destinations where it is further processed in food products such as chocolate.
Therefore, there remains a need to both reduce and/or replace the usage of conventional cocoa obtained from the cocoa tree with a cocoa substitute which is based on natural starting products and which has similar characteristics such as flavor profiles and odor, and can be applied in the same way as conventional cocoa.
There also remains a need to provide a confectionery product in which the usage of conventional cocoa obtained from the cocoa tree can be substantially reduced or even avoided, wherein the confectionery product nevertheless has similar characteristics such as flavor profiles and odor as typical confectionery products with chocolate flavor.
It would be even more advantageous if the natural starting products on which the cocoa substitute is based are byproducts of other production processes which usually are of little economic value anymore or find limited further application, such as kernels and pomace in the production of jams and juices.
It would also be even more advantageous if the natural starting products on which the confectionery product is based and which impart the flavor, for example, the chocolate flavor, are byproducts of other production processes which usually are of little economic value anymore or find limited further application, such as kernels and pomace in the production of jams and juices.
The inventors surprisingly found that the inventive flavor composition meets the above-referenced needs. In particular, the inventors surprisingly found that the inventive flavor composition could be adjusted, mimicking flavor profiles of different cocoa types, e.g. so-called Forastero cocoa (Theobroma cacao IFC-1), and/or the flavor profiles of chocolates, including dairy-like and buttery aroma notes, usually not found in cocoa.

The following examples illustrate the present invention. They are intended to aid in the understanding of the invention, and they should not be construed to in any way limit the scope of the invention.
Apricot kernels were pre-treated to remove residual cyanide. 500 g of apricot kernels were placed in a container, and 5 L of water was added. The apricot kernels were soaked for 24 hours, the water was drained and another 5 L was added (replenished), with the kernels being soaked for an additional 24 hours. The water was drained again, and the kernels were dried at 90° C. for 12 hours.
100 g of the pre-treated apricot kernels were placed in a beaker, and 100 mL water, 5 g glucose, 0.75 g leucine, 0.75 g isoleucine, 0.5 g phenylalanine, and 1 g glycine were added. For incubation, the mixture was heated to 90° C. on a hot plate while stirring and kept at that temperature for 15 min. The mixture was then placed in an electric oven at 90° C. for 12 hours to dry. The apricot kernels were roasted in a drum roaster for 6.5 min at 170° C. The flavor was intensely cocoa- and chocolate-like, with subtle notes of sweet and roasted aroma.
100 g of untreated, hulless oat (Avena nuda) grains were placed in a beaker, and 100 ml water, 5 g glucose, 0.75 g leucine, 0.75 g isoleucine, 0.5 g phenylalanine, and 1 g glycine were added. For incubation, the mixture was heated to 90° C. on a hot plate while stirring and kept at that temperature for 15 min. The mixture was then placed in an electric oven at 90° C. for 12 hours to dry. After the same drying, the mixture was roasted in a drum roaster for 6.5 min at 170° C. The grains' flavor was intensely cocoa- and chocolate-like, with subtle notes of cereal and roasted aroma. After roasting and grinding, the roasted apricot kernels and hulless oats were mixed 70/30 (w/w) and ground using a ball mill to a particle size D50 of about 600 μm. The obtained flavor composition can then be applied as a cocoa powder substitute.

Formulation: 120 g of the flavor composition of Example 1, 339 g of cocoa butter equivalent (commercially available, based on palm fat, and shea butter), 319 g of sugar, 209 g of oat flour, and 9 g of dried Aronia powder were mixed to produce 1 kg of milk-chocolate substitute mass. Milling: The mass was milled (3-roll roller grinder) to produce fine particles (D90, laser diffraction) of <30 μm.
Conching: The finely milled mass was then transferred into a conching device (Elkolino Conche, Buhler, Switzerland). The conching device was set to 60° C. and 1000 rpm for 2 hours. In the first hour, the conche was left open to remove residual light volatile acids, before the conching device was closed for the remaining 1 hour. At the end of the 2 hours, 20 minutes before stopping the conching, the lid was removed again and 4 g soy lecithin was added. The chocolate substitute was removed from the conche, tempered, and used like conventional chocolate, by molding the chocolate substitute into bars. The chocolate had a brownish color, similar to conventional dairy chocolate, and an intense chocolate-like, dairy, and creamy aroma. After cooling down and hardening, the bars had a shiny, firm surface, comparable to conventional dairy chocolate.

Formulation: 300 g flavor composition obtained in Example 3 and 300 g of flavor composition obtained in Example 4, 2100 g lactose, 1700 g cocoa butter equivalent (commercially available, derived from AAK based on palm fat, and shea butter), 800 g skimmed milk powder, and 160 g butter fat were mixed to produce the chocolate substitute mass.
Milling: The mass was milled using a melangeur (stone grinder) for 48 hours and a particle size distribution (D90) of <20 μm, as determined by light scattering analysis, was obtained.
Milling and conching: The milled mass was then transferred into a melangeur (a melangeur is a rotating stone grinder, heat is produced by the friction of the stone grinders with the material and the bottom stone plate). The mass was conched using this melangeur. Due to the friction of the stones, the temperature in the mass was increased to 55° C. and kept at that temperature for 40 hours. After a total of 48 hours, 5 g vanillin and 5 g soy lecithin were added and after an additional 10 minutes of mixing, the melangeur was stopped. The finalized chocolate substitute mass was analyzed by means of the particle size distribution (D90, laser diffraction), and a particle size of <20 μm, was determined. The chocolate substitute mass was molded into confectionery products (e.g., by using praline and chocolate bar molds and filled with different fillings, such as marzipan, caramel, and nuts (e.g., peanuts)). The flavor of these chocolate substitute bars was mildly bitter, with a tart, mild acidity, and showed a strong chocolate-like, nutty and creamy aroma. The overall flavor was comparable to commercially available confectionery bars.
