## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims benefit of priority to PCT/EP2006/060463, which published as WO2007/098809, filed on Mar. 3, 2006, the disclosure of which is incorporated herein by reference in its entirety.
The present invention relates to a pressed agglomerate (compacted material) which is suitable for consumption, a process for its preparation, its use for aromatizing and/or flavoring products and products comprising such a pressed agglomerate.
The aromatization of products which are suitable for consumption has been known for a long time. Either liquid aromas, solid aromas (i.e. aromas applied to solid carriers, e.g. spray-dried aromas, or aromas enclosed in solid carriers) or also dried pieces of plants are conventionally used in this procedure.
It is desirable to produce new types of consumable products, for example based on cold water soluble aromatized products, allowing the consumer to perceive different sensory experiences (in particular gustatory, nasal and optionally optical) sequentially on consumption of said consumable products. It is further desirable to provide consumable products, in particular foodstuffs or beverages, in powdered form.
On the market are powdered soft drink mixes that change color while providing a flavor when mixed with water. Powdered soft drink mixes that change flavor are not available.
Kool-Aid Magic TwistsTM from Kraft Foods for example is available as “Changin' Cherry”, a green drink powder that turns blue, and has a red cherry flavor; and as “Grape Illusion”, a gold powder that changes to red and has a purple grape flavor. The change in color takes place within less than 30 seconds.
An aroma in the context of the present invention comprises at least one aroma substance, but usually two or more different aroma substances. Aromas typically are complex mixtures of volatile components (aroma substances). In particular, aroma substances in the context of the present invention are sensorially active substances having a vapor pressure of at least 0.01 Pa at 25° C., more preferably a vapor pressure of at least 0.025 Pa at 25° C. Aroma substances in large part show a vapor pressure of at least 0.5 Pa at 25° C., therefore such aroma substances in particular are meant by the term volatile component (aroma substance).
When mixed with cold water uncompacted spray-dried aromas (i.e. in powder-form) dissolve rapidly, a very fast uniform release of the aroma substance(s) occurs and retarded release of the aroma substance(s) is not achievable.
Certain pressed agglomerates, mostly prepared by compacting, based on spray-dried aromas are already commercially available. Compacted spray-dried aromas, when mixed with cold water, show a fast release of the aroma substance(s), to a considerable extent depending on the particle size, a retarded release of the aroma substance(s) is not achievable. WO 2004/049827 describes a granulated flavor which releases flavor immediately when needed.
One possibility to alter the release properties and to retard release of aroma substance(s) from compacted spray-dried aromas is to apply a coating to compacted spray-dried aromas, said coating having a barrier function to a certain extent against cold water.
It was therefore the primary object of the present invention to provide particles that allow a controlled, in particular a retarded, release of aroma substance(s) in cold water. In addition, these particles should be as easy as possible to prepare. Moreover these particles should have a high stability, in particular should the particles be mechanically stable and be stable to oxidation.
It was a secondary object of the present invention to provide consumables (consumable products) that afford a retarded release of aroma substance(s) when mixed with cold water, such as cold process and instant (powdered) foodstuffs or beverages. In particular a sequential flavor release is desired during use and consumption of said consumable products when mixed with cold water, in order to allow the consumer to experience two or more different flavor directions (and optionally one or more changes in color) during consumption.
According to a first aspect of the present invention, this object is achieved by a pressed agglomerate which is suitable for consumption, comprising or consisting of:
a) aroma (spray-dried or not),
b) optionally maltodextrin,
c) 1-60 wt. % of one or more cold water swellable starches, and
d) optionally one or more coloring agents which are suitable for consumption,
wherein weight percent values are based on the total weight of the pressed agglomerate.
Herein and in all following descriptions of a pressed agglomerate, weight percent values are based on the total weight of the pressed agglomerate.
According to a second aspect of the present invention, this object is also achieved by a pressed agglomerate which is suitable for consumption and comprises or consists of:
a) aroma (spray-dried or not),
b) maltodextrin (e.g. as a carrier substance, if the aroma is spray-dried),
c) 1-60 wt. % of one or more cold water swellable starches, and
d) optionally one or more coloring agents which are suitable for consumption.
According to a third aspect of the present invention, this object is achieved by a pressed agglomerate which is suitable for consumption and comprises or consists of:
a) 30-95 wt. % spray-dried aroma,
b) optionally maltodextrin,
c) 1-60 wt. % of one or more cold water swellable starches, and
d) optionally one or more coloring agents which are suitable for consumption.
The weight percent value of spray-dried aroma means the weight percent value of the complete spray-dried product including aroma substances, other constituents of the aroma, and carrier substances.
One advantage of pressed agglomerates according to the first, second or third aspect of the present invention is that the flavor of the pressed agglomerates according to the invention can be adjusted in strength (intensity) and profile almost as desired, so that, as required, these can make a significant flavor contribution in a product which is suitable for consumption (consumable) containing them. With the pressed agglomerates according to the invention it is possible to aromatize or flavor a consumable product completely and comprehensively, i.e. without addition of a further, optionally liquid, aroma. The pressed agglomerates according to the invention moreover are easy to prepare (see below).
It has furthermore been found that the pressed agglomerates according to the invention are considerably stable to oxidation. After completion of an oxidative stress test, which simulated a storage time of about 12 months at 20° C., the pressed agglomerates according to the invention showed a small decrease in sensory quality. When tasted at the end of the oxidative stress test, the pressed agglomerates according to the invention the original flavor was still clearly detectable.
A spray-dried aroma in the context of the present invention comprises at least one aroma substance (volatile) and at least one non-volatile carrier substance, which can itself be a flavoring substance, but does not have to be (such as e.g. the preferred maltodextrin). Conventional spray-dried aromas comprise at least a carrier substance, an aroma (which can also be an individual aroma substance) and further substances, such as, for example, an emulsifying substance.
Aroma encapsulation by means of spray drying, as described, for example, in U.S. Pat. No. 3,159,585, U.S. Pat. No. 3,971,852, U.S. Pat. No. 4,532,145 or U.S. Pat. No. 5,124,162, is conventional in this art. Spray-dried aromas are commercially obtainable in many different flavor directions and particle sizes.
The aroma loading of spray-dried aroma (amount of aroma in spray-dried aroma) for use in pressed agglomerates according to the invention can be varied within wide ranges, depending on the requirement and the desired sensory profile. The aroma loading advantageously is in the range of 1 to 70 wt. %, preferably in the range of 5 to 40 wt. %, more preferably in the range of 10 to 30 wt. %, based on the total weight of the spray-dried aroma.
Preferably, the weight percent value of aroma means the total weight percent value of volatile aroma substances.
Individual substances or substance mixtures can be employed as carrier substances for the aroma (as constituent a) of a pressed agglomerate according to the first, but in particular the second or third aspect of the invention). Advantageous carrier substances are carbohydrates and/or carbohydrate polymers (polysaccharides). Carrier substances which may be mentioned are, for example, hydrocolloids, such as starches, degraded starches, chemically or physically modified starches, modified celluloses, gum arabic (acacia gum), ghatti gum, tragacanth, karaya, carrageenan, guar bean flour, carob bean flour, alginates, pectin, inulin or xanthan gum.
The degree of decomposition of starch is measured by the “dextrose equivalent” (DE) index, which can assume the limit values of 0 for the long-chain glucose polymer and 100 for pure glucose.
Preferred carrier substances for the aroma (as constituent a) of a pressed agglomerate according to the first, but in particular the second or third aspect of the invention) are derived from starch and have DE values in the range of 5-45, preferably in the range from 10 to 40. The carrier substances present in a pressed agglomerate according to the present invention preferably has an averaged DE value in the range of 18-38. Particularly preferred carrier substances are dextrins and maltodextrins, dextrins having DE values in the range of 30-38 and maltodextrins having DE values in the range of 18-35 in turn are preferred. The content of maltodextrins is preferably in the range of 30-90 wt. %, preferably in the range of 40-80 wt. %, based on the total weight of the pressed agglomerate.
It is irrelevant here which plant has originally supplied the starch for the preparation of the dextrins and maltodextrins. Maize-based raw materials are suitable and readily available, and in order to ensure a product which is free from genetically modified constituents, for example, raw materials from tapioca, manioc, rice, wheat and potatoes can also be employed.
The term maltodextrin also includes mixtures of various maltodextrins. What maltodextrin, in particular with what DE values, is employed depends, inter alia, on the remaining constituents of the dry mixture to be compacted (see below), from which the pressed agglomerates according to the invention are prepared. If fruit powders are used in particular, as described in more detail below, maltodextrins having comparatively low DE values are recommended, preferably having DE values in the range of 5-20. Since fruit powders contain a noticeable content of low molecular weight sugars, which in part have a hygroscopic action (inter alia mono- and disaccharides) and which can adversely influence the processability of the dry mixture to be compacted, the less hygroscopic maltodextrins having DE values in the range of 5-15 are advantageous here.
The aroma loading (amount of aroma, spray-dried or not) of pressed agglomerates according to the present invention can be varied within wide ranges, depending on the requirement and the desired sensory profile. The aroma loading advantageously is in the range of 0.1 to 40 wt. %, preferably in the range of 0.5 to 30 wt. %, more preferably in the range of 1 to 25 wt. %, based on the total weight of the pressed agglomerate.
Possible aromas are, for example, essential oils, fractions thereof, or individual aroma substances. Examples which may be mentioned are: extracts from natural raw materials, such as essential oils, concretes, absolutes, resins, resinoids, balsams and tinctures, such as aniseed oil; basil oil; bergamot oil; bitter almond oil; camphor oil; lemon oil; eucalyptus oil; geranium oil; grapefruit oil; ginger oil; camomile oil; spearmint oil, caraway oil, lime oil; mandarin oil; clove (blossom) oil, orange oil; peppermint oil; rose oil; rosemary oil; sage oil; yarrow oil; star aniseed oil; thyme oil; vanilla extract; juniper berry oil; wintergreen oil; cinnamon leaf oil; cinnamon bark oil; and fractions thereof and constituents isolated therefrom.
Individual aroma substances which can be a constituent of the aroma are, for example, from the following classes of substances: aliphatic esters (saturated and unsaturated), e.g. ethyl butyrate, allyl caproate; aromatic esters, e.g. benzyl acetate, methyl salicylate; organic aliphatic acids (saturated and unsaturated) e.g. acetic acid, caproic acid; organic aromatic acids; aliphatic alcohols (saturated and unsaturated); cyclic alcohols, e.g. menthol; aromatic alcohols, e.g. benzyl alcohol; aliphatic aldehydes (saturated and unsaturated) e.g. acetaldehyde; aromatic aldehydes, e.g. benzaldehyde; vanillin; ketones, e.g. menthone; cyclic ethers, e.g. 4-hydroxy-5-methylfuranone; aromatic ethers, e.g. p-methoxybenzaldehyde, guaiacol; lactones, e.g. gamma-decalactone; terpenes, e.g. limonene, linalool, terpinene, terpineol, citral.
In particular in the case of the second aspect of the invention, the aromas can also be introduced in the form of fruit juice concentrates, fruit pulps or fruit purees, i.e. in the form of thickened natural fruit products. After spray drying of fruit juice concentrates, fruit pulps or fruit purees, the resulting spray-dried aroma is called fruit powder; these fruit powders can advantageously be employed according to the second aspect and according to the third aspect of the invention.
A procedure can also be followed in which fruit juice concentrate, fruit pulps or fruit puree are employed together with a natural and/or nature-identical aroma in a or as a spray solution for the preparation of a spray-dried aroma to be used according to the invention.
In a preferred embodiment of the present invention, the pressed agglomerate comprises a fruit powder and one or more aroma substances which do not originate from a fruit.
Preferred aromas and flavors (flavor directions) of aromas in the context of the present invention are: fruits (e.g. berries, citrus, pomaceous fruit), vanilla, chocolate, coffee, spices, herbs, nuts, alcoholic beverages and mints.
Particularly preferred aromas are aromas of the flavor directions of pineapple, apple, apricot, banana, pear, blackberry, lemon, strawberry, grapefruit, guava, rose hip, blueberry, raspberry, elderberry, currant (red or black), cherry, kiwi, mandarin, mango, yellow plum, orange, papaya, passion fruit, peach, prune, melon (water melon, sugar melon or honeydew melon), tamarind, grape (red or white), plum, chocolate (white, dark, milk and the like), coffee (plain, cappuccino, espresso, latte macchiato and the like), vanillin, vanilla, cardamom, anise, nutmeg, clove, thyme, camomille, cinnamon, rum, whisk(e)y, amaretto, red wine, cognac, vodka (unflavored or flavored), irish cream, coffee liqour, hazelnut, almond, spearmint, eucalyptus, menthol and peppermint.
Conventional additives and ingredients can also be added to a spray solution for the preparation of a spray-dried aroma, to be employed according to the invention, such as coloring agents, sweeteners, food acids, antioxidants, flavor-influencing substances, such as sodium glutamate, vitamins, minerals etc., so that the spray-dried aromas employed according to the invention can also contain such additives.
Spray-dried aromas which can be used according to the invention preferably have particle sizes in the range of 10 to 500 micrometers, preferably an average particle size (median value) in the range of 30 to 200 micrometers.
Pressed agglomerates according to the invention contain as constituent c) one or more cold water swellable (swelling) starches (CWSs). Cold water swellable starch (CWS) is also known as pre-gelatinized starch, pre-cooked starch, pre-gelled starch, instant starch, swell-starch flour, cold water starch, cold water soluble starch or cold water dispersible starch. Cold water swellable starches are also readily available in granular form (also referred to as GCWS) which may also be employed in the present invention.
The CWSs for use in the present invention, upon hydration at ambient temperature (20° C.), form a gel-like structure which is further characterized by its ability to retain moisture.
CWSs, when dispersed in water with a temperature below the swelling temperature of starch (i.e., dependent on the origin of the starch, below about 50-70° C.), increase the viscosity of the liquid without the need for further heating. One part of pregelatinized starch may absorb up to 15 parts of water and give a viscous liquid or gel. CWSs are used in instant pudding and gravy mixes.
CWSs are well known and available in several qualities from numerous manufacturers, e.g. Advanta-GelTM from National Starch, Merigel or Mira-Gel® from A.E. Staley/Tate & Lyle, Paselli Easy-GelTM from Avebe Food, Pure-Gel® or Inscosity® from Grain Processing Corporation, C* HiFormTM from Cerestar/Cargill, or ColdSwell from KMC. Mixtures of cold water swellable starches can of course also be used.
It is not important here which plant has originally supplied the starch for the preparation of the cold water swellable starches. Suitable and readily available CWSs typically are based on maize or corn (e.g. waxy or dent maize) and potato-based (potato or sweet potato); starches from other plants (e.g. wheat, rice, tapioca, mung bean, (waxy) barley or sago) can also be employed. By way of example, the following patents describe cold water swellable starches: U.S. Pat. No. 4,207,355; U.S. Pat. No. 4,228,199, U.S. Pat. No. 4,391,836; U.S. Pat. No. 4,465,702; U.S. Pat. No. 5,037,929; US 2005/0048190 A1.
According to the first aspect, the second aspect and the third aspect of the present invention, the content of cold water swellable starches is in the range of 1-60 wt. %, preferably in the range of 2-40 wt. %, more preferably in the range of 5-25 wt. %, based on the total weight of the pressed agglomerate.
According to the present invention (all aspects), CWSs having a cold water solubility of at least 50 wt. % are preferred. CWSs having a cold water solubility of 70 wt. % or higher are preferred, most preferably is a cold water solubility of 75 wt. % or higher (measured according to U.S. Pat. No. 4,465,702 at a water temperature of 20° C. at 1013 mbar). Cold water solubility as used in characterizing the CWSs is determined by mixing a known weight of starch in a measured volume of distilled water at 20° C. with a blender (e.g. a Waring blender), centrifuging the starch suspension and weighing the residue obtained by evaporation of a measured aliquot of the supernatant liquid. The water solubility of the starch sample is expressed as % water solubles, dry substance basis. A specific procedure for measuring cold water solubility of starch samples is described in U.S. Pat. No. 4,465,702 at col. 11 line 49 to col. 12 line 20. This procedure is herein incorporated by reference.
According to the present invention, the CWSs preferably have a fat content of less than 0.5 wt. %, more preferably of less than 0.25 wt. %.
Numerous applications and products of CWSs are known, such as in instant puddings (U.S. Pat. No. 3,583,874), meat-based jerky products (U.S. Pat. No. 5,731,029), meat-based strip-shaped molded products (US 2005/0048189), cold process bake fruit pastes (U.S. Pat. No. 5,932,270, U.S. Pat. No. 6,391,376) or frozen baked goods (US 2005/0191387).
The pressed agglomerates according to the present invention (first aspect, second aspect and third aspect) are preferably free of (processed) meat (i.e. free of ground beef, emulsified chicken meat and the like).
The pressed agglomerates according to the present invention show the desired retarded aroma release: when stirred in cold water the aroma (and optionally further present ingredients such as coloring agent(s)) typically is released within the range of 30 seconds to 8 minutes, preferably in the range of 60 seconds to 5 minutes, strongly depending on the amount of CWS incorporated into the pressed agglomerates of the present invention. The given ranges refer to the period of time until complete dissolution of the pressed agglomerates according to the present invention in water (20° C.) occurs, measured with stirring at about 300 rpm. The higher the amount of CWS, the slower the release of aroma (and optionally further present ingredients). It is not necessary to apply a coating to the pressed agglomerates according to the present invention to obtain a retarded aroma release. Preferably, the pressed agglomerates according to the present invention are coating-free.

The constituents (as listed above) for the preparation of a pressed agglomerate according to the invention are conventionally mixed and homogenized to form a dry mixture before carrying out a pressing agglomeration (compaction). Conventional mixers, advantageously fluidizing mixers, e.g. plough share mixers (exemplary manufacturer: Lödige), can be employed for the preparation of the dry mixture to be compacted.
The process of pressing agglomeration is understood as meaning a dry agglomeration in which as a rule a dry bulk material of smaller particles is compressed by pressing tools to form larger particles, the pressed agglomerate. In this procedure, in contrast to wet agglomeration, no material bridges are formed and there is no addition of binders. External forces are exerted on the particles by the pressing tools, so that many contacts with small contact distances are established, as a result of which interactions effect the cohesion in the pressed agglomerate at the molecular level, in particular van der Waals forces.
The pressing agglomeration can be carried out by compression or by extrusion, compression being preferred.
In the case of extrusion, ram, strand or perforated die extrusion, for example, can be employed.
According to the invention, the pressing agglomeration is preferably carried out by means of compression with roll pressure machines or presses. In this procedure, the compression is usually carried out either by a ram and template or by rollers with smooth or profiled surfaces running in opposite directions. In addition, embodiments such as a roller press with a perforated template or a toothed wheel perforated press are advantageous.
Roller pressing with a roller compactor with smooth rollers or forming rollers (e.g. tablet-making or briquette-making) is particularly preferred. During roller pressing with smooth rollers, which is in turn advantageous here, a flake is first formed, which is then reduced, i.e. granulated, to the desired granule size, optionally after pre-crushing. This may occur in a single-stage or multi-stage granulation process. The thickness of the flake depends on the distance of the rollers, and the thickness of the flake is typically in the range of 0.1 to 3 mm. In the case of tablet-making or briquette-making, the dry mixture to be compacted can be pressed to relatively large tablets or briquettes in a first step, which are then broken down by means of granulation in a second step.
The granules formed in the granulation (fragmentation) of the flake, briquette or tablet are called broken granules. As a rule, the broken granules are sieved in a further working step, and an upper and lower particle size can be established via the mesh width of the sieves. The fine fraction thereby obtained can be recycled into the compression, and the larger particles separated off by means of sieving can be introduced into the fragmentation again.
The broken granules preferably have an average particle size, in particular after sieving, in the range of 0.3 mm (300 μm) to 5 mm, more preferably from 0.5 mm (500 μm) to 2 mm.
According to the invention, the compression pressure during the roller pressing is usually in the range of 50 to 250 bar, preferably in the range of 70 to 150 bar. At higher pressures, in particular above 100 bar, and depending on the carrier substance/maltodextrin used, an increasing proportion of the pressed agglomerates according to the invention become glassy, i.e. exhibit a glass transition temperature (maltodextrins with higher DE values form a glass more easily).
Roller compactors are commercially obtainable, for example from the companies Hosokawa Bepex GmbH (Germany) or Gerteis Maschinen-und Processengineering (Switzerland).
The present invention furthermore provides a product, in particular a product which is suitable for consumption, comprising a pressed agglomerate, preferably a multiplicity of pressed agglomerates according to the invention, or a mixture of different pressed agglomerates, each of the different pressed agglomerates being an agglomerate according to the invention (in each case preferably in one of the preferred embodiments).
