DETAILED DESCRIPTION OF THE INVENTION

[0015] The present invention combines snack and drink product in a combo package such that consumer benefits both the pleasures from one product alone.

[0016] Thus in a first aspect, the present invention relates to a food product comprising a snack comprising at least one sealed edible hollow container filled with a free flowable edible solid; wherein the container is configured to release the edible solid to be consumed in its present form or reconstituted with a liquid.

[0017] In an embodiment of the present invention, the snack comprises means to rupture the surface of the container to release the edible solids. The term “means” refers to different ways of opening and emptying the container of the edible solids. One way is rupturing the container such as for instance breaking by applying physical pressure/force on the surface of the container such as a snapping action or biting the container. Another way is that the container includes a portion which can be dissolved/melted in order to release the edible solids. For instance a portion of the container may comprise a composition such that this composition dissolves/melts by stirring action in a hot liquid. The container may also comprise a pre-cut segment (see FIG. 1) to facilitate the rupture of the container in an intact manner and at the appropriate position on the surface of the container. The container may also comprise a gas or gas generating composition that reacts upon reconstitution with water to generate or release gas (e.g. acid-base).

[0018] In another embodiment of the present invention, the edible hollow container may function as a stirrer or a straw for the reconstituted edible solids.

[0019] In an embodiment of the present invention, the snack of the present invention comprising the container and the edible solids have a water activity below 0.5. The water activity may be below 0.3. A conditioning process is applied to bring the water activity of the container to be equivalent to the water activity of the powder that will be filled in the container. For example the conditioning of container such as wafer is exposed to an environment such that a diffusion of moisture takes place.

[0020] The term “edible hollow container” may refer to a biscuit, cookie or a wafer. The container may be based on cereal, savory and/or sweet. Such containers may comprise ingredients used in FBFs or high-energy biscuits. The biscuit may comprise a whole grain component obtained from different sources including hydrolysed whole grain. WO2012/076051 describes whole grain composition and hydrolysed forms thus providing a basis for a healthy snack. Examples of whole grain sources are semolina, cones, grits, flour and micronized grain (micronized flour). The whole grains may be ground (milled), preferably by dry milling. Such milling preferably takes place before the whole grain component is contacted with the enzyme composition according to the invention. In an embodiment of the present invention the whole grain component may be heat treated to limit rancidity and microbial count.

[0021] In one embodiment of the present, the edible hollow container is a wafer and wherein the sugar in the composition of wafer is less than 10% w/w, for instance less than 7% w/w of the total dry weight basis of the wafer composition.

[0022] Whole grains are non-processed cereals of monocotyledonous plants of the Poaceae family (grass family) cultivated for their edible, starchy grains. Examples of whole grain cereals include barley, rice, black rice, brown rice, wild rice, corn (maize), millet, oat, sorghum, spelt, triticale, rye, wheat, teff, canary grass, Job's tears and fonio. Plant species that do not belong to the grass family but which also produce starchy seeds or fruits that may be used in the same way as cereal grains are called pseudo-cereals. Examples of pseudo-cereals include amaranth, buckwheat, tartar buckwheat and quinoa. When designating cereals, this will include both cereal and pseudo-cereals. In general the source of grain used in a recipe depends on the desired product type, since each grain will provide its own taste profile and processing characteristics

[0023] Whole grain components are components made from unrefined cereal grains. Whole grain components comprise the entire edible parts of a grain; i.e. the germ, the endosperm and the bran. Whole grain components may be provided in a variety of forms such as ground, flaked, cracked or other forms, as is commonly known in the milling industry.

[0024] The container may also contain additional flavoring agents such as coffee, chocolate, vanilla, cinnamon, fruit which enhances the smell of the product. Often these flavors partly disappear during the baking process. Therefore in one embodiment precursors are added to generate flavors during the heating or baking process. For instance in-process flavor generation could be obtained through a Maillard reaction using amino acid and Thiamin based precursors. The cereal-based container may also contain healthy substances like vitamins, minerals, antioxidants, fibers, bioactives, healthy oils, fruits, herbs, plants, milk solids, nuts. For instance if the edible solid is a soup powder, the edible container may be a salty savory biscuit to complement the soup beverage.

[0025] Such edible hollow container may be produced by a thermo shaping process including extrusion, sintering wafer and/or biscuit technology.

[0026] The term “sealed edible hollow container” may refer to sealing both or at least one end of the container. For instance Extrusion process may produce an edible hollow container with one open end wherein the container can be filled with edible solids and this open end may be sealed with a hydrophobic or hydrophilic material or a blend of both. For instance, the open end of edible hollow container may be closed with a blend of polysaccharides, fat and proteins. In another instance the container may be cylindrical/barrel shaped having open ends on both sides and both ends are sealed with a hydrophobic or hydrophilic material or a blend of both. These substances apart from providing a sealing for the container also functions to keep the edible solids inside the container in a dry form. In another embodiment the edible hollow container are produced using wafer technology wherein edible hollow containers consists of two halves wherein one half is filled with the edible solid and subsequently sealed with the other half of the wafer.

[0027] The term “hydrophobic material” refers to any fat or oil containing substances such as vegetable fat, milk fat, animal fat, bees wax or combinations thereof. One form of vegetable fat may be cocoa butter.

[0028] The term “hydrophilic material” refers to substances such as sugars, salts, hydrocolloids, hydrophilic polymers like starch, alginate, carrageenan, carboxymethylcellulose, gum arabic, chitosan, pectin, and xanthan gum.

[0029] The term “edible solids” refers to a free-flowable dehydrated food product in powder or sphere or granular form which stays dry in the hollow container and can be released by rupturing the surface of the container. Edible solids may refer to beverage ingredients such as coffee, coffee mixes, tea, chocolate powder, soups etc. Coffee such as soluble coffee in all known blends, coffee mixes with cream and/or sugar, roast and ground and/or micronized form Edible solids may also comprise aromatizing agent in order to prepare aromatized drinks such as fruit flavoured water, or coffee, cocoa or vanilla flavoured milk, for example. The present aromatizing agent may also be used in addition to a dehydrated food product to be reconstituted in water, such as soups and sauces, especially powdered soups and sauces or instant noodles, or in milk, such as nutritious, especially powdered cocoa beverages, for example.

[0030] The term “free-flowable” refers to the dry nature of the edible solids such that the edible solids are released from the edible container such that the edible hollow container is emptied.

[0031] In an embodiment ofthe present invention, the edible hollow container comprises a cereal extruded biscuit filled with soluble coffee as edible solids.

[0032] In another embodiment of the present invention, the snack product comprises at least three sealed edible hollow containers filled with a free flowable beverage powder, wherein first one comprises coffee, second one comprises cream and third comprises sugar.

[0033] It should be noted that embodiments and features described in the context of one of the aspects or embodiments of the present invention also apply to the other aspects of the invention. The invention will now be described in further details in the following non-limiting examples.

EXAMPLES

Example 1

[0034] The dry ingredients are mixed according to the formulations given in table 1 below. Four different recipes were prepared. The mix is fed to a cooking extruder where powders are mixed with water and then cooked through the extrusion process. Extrusion temperature profile is spread in the range of 20 to 145° C. (Product temperature may range between 120-180° C.). Screw speed of 260 RPM (180-400 RPM). The process conditions for each of the recipes are defined in table 2 below.

[0035] The hot product is pushed out of the extruder, creating a pressure at the die exit (Product pressure, table 2). Coming out of the die, the pressure drops to ambient (1 atmosphere) and with the instant water evaporation the product expand and dry out to create the final product, a tube in this case. The Product is cut to pieces and then dry in a drying oven to <3% moisture. In some cases the product was crimped on one edge, to give only one opened edge.

[0036] The resulted tubes, opened on one or two edges. If two edges were opened then one was closed by dipping into chocolate, let cool to solidify. Powder filling was done manually by filling and weight control to assure correct amount of filling. The yet opened edge was now blocked by a fragile piece of biscuit and then sealed by dipping into chocolate.
