Patent Description:
A bouillon tablet formed by compressing ingredients into a tablet shape, for example a cube, is widely used as a concentrate to prepare a bouillon, a broth or a soup. The bouillon tablet is normally added to a hot aqueous solution, allowing it to dissolve. In addition, a bouillon tablet may be used when preparing other dishes, as a seasoning product. The dissolution time of bouillon tablets highly depends on its degree of compaction which can be measured / expressed by the hardness of such a product. The reason to compact powders in a regular form presents several advantages for the commercialisation (e.g. reduction of volume, optimisation of packaging material usage, shelf life and convenience). A habit developed by users of bouillon tablets is the crumbling of the tablet or cube into the dish during preparation process either to ensure good distribution and or to accelerate its dissolution time in the cooking water. This crumbliness is one of the attributes that needs to be ensured during shelf life and therefore a post-hardening of the tablet or cube has to be avoided. A minimum hardness is necessary to allow a wrapping of the tablet. A maximum hardness ensures that a normal user can break the tablet within fingers without the use of additional tools or appliances. A typical bouillon tablet or bouillon cube comprises salts, taste enhancing compounds like monosodium glutamate (MSG), sugars, starch or flour, fat, flavouring components, vegetables, meat extracts, spices, colourants etc. The amounts of the respective compounds may vary depending on the specific purpose of the product, the market or taste of the consumer that is aimed at.

A conventional way of manufacturing bouillon tablets comprises mixing powdered bouillon components with fat and pressing the mix into a tablet. In this type of bouillon tablet the fat is the main ingredient holding the structure together.

Nowadays there is a nutritional trend to avoid or at least reduce the consumption of fats rich in saturated fatty acids and to preferably consume oils rich in monounsaturated fatty acids and/or polyunsaturated fatty acids. <CIT> describes how it is possible to have very little solid fat entrapped in a hard bouillon tablet provided the tablet also comprises crystals, a filler and a sticking agent. The sticking agent may comprise ingredients the addition of which (combined with an adequate increase of the water activity) impart a glass transition temperature to the final mixture which may be relatively easily exceeded during tableting. Such ingredients include meat extract, processed flavours and/or vegetables extracts.

Sticking agents used to bind together bouillon cubes with low fat contents are typically hygroscopic amorphous ingredients. These are activated in the bouillon mixture by the addition of water. This process of water addition can be problematic, for example it is difficult to ensure homogenous distribution of the water and a storage time up to <NUM> hours is needed to reach a water activity equilibrium. Crust formation may occur which requires stopping the mixer for cleaning. Sometimes lumps are formed in the mixtures which causes quality defects in the finished pressed tablets. In addition post hardening of the bouillon tablet may occur.

<CIT> discloses a bouillon and/or seasoning tablet, which comprises <NUM> to 10wt% oil and/or <NUM> to 5wt% fat, binders, salt, between <NUM> and 3wt% of total water, and between <NUM> to 8wt% of cereal, vegetable or fruit fibers. The fibers are wetted with a saturated water/salt solution and afterwards the wetted fibers are mixed with all the other ingredients and the obtained mixture is mixed.

<CIT> discloses a method for manufacturing a soup compact. The method describes compressing a soup powder, moistening the compressed soup powder and afterwards drying. Through the moistening and drying a very thin layer of crust is formed.

<CIT> discloses a shaped solid food concentrate comprising <NUM>-<NUM>% by weight crystalline ingredients composed of at least one of salt, monosodium glutamate and sugar, <NUM>-<NUM>% by weight gelatinized starch, <NUM>-<NUM>% by weight water; and <NUM>-<NUM>% by weight of taste imparting components.

<CIT> disclosed a food flavor enhancer composition which may be comprised of a variety or any one of edible salts including sodium chloride, potassium chloride, monosodium glutamate, flavor potentiators and at least one variety of soluble dietary fibers which is preferably decomplexed is specified.

Hence, there is a persisting need in the art to find improved processes for forming bouillon tablets, especially bouillon tablets which use a new binding system despite the well-known binding system of amorphous binding and/or fat binding.

An object of the present invention is to improve the state of the art and to provide an improved solution to overcome at least some of the inconveniences described above or at least to provide a useful alternative. The object of the present invention is achieved by the subject matter of the independent claims. The dependent claims further develop the idea of the present invention.

Accordingly, the present invention provides in a first aspect a process for the production of a bouillon tablet comprising salt and fibers, the process comprising the steps of:.

wherein the salt is dissolved in the water at a ratio between <NUM>:<NUM> to <NUM>:<NUM>; and wherein the drying is done at a temperature between <NUM> to <NUM>; and wherein the bouillon tablet comprises at least 10wt% salt-fiber mass; and wherein the salt-fiber mass comprises <NUM> to 90wt% salt and <NUM> to 90wt% fibers.

It has been surprisingly found by the inventors that using a co-processed salt-fiber mass has very good flow-ability values and provides an efficient new binding system in a bouillon tablet.

The use of the salt-fiber mass increases the hardness of bouillon tablets/cubes after pressing. The obtained hardness can exceed the hardness that is commonly observed during pressing of bouillon cubes/tablets. At the same time, the produced bouillon products can still be crumbled. So far, such a behaviour has not been observed for comparable hardness values. This strongly indicates that a different and new binding mechanism is present. Due to this, cubes/tablets can be easily produced (high hardness advantageous for manufacturing) but at the same time show good crumbliness. Crumbliness is a key Driver of liking for consumers and is thus desired. In addition the bouillon tablets/cubes has a faster dissolution time compared to standard bouillon tablets/cubes. This is very surprising as due to the higher hardness a slower dissolution time is expected.

In addition the salt-fiber mass is used to produce bouillon cubes with reduced salt content (e.g. between <NUM> to <NUM>% reduction). It was surprisingly found that cubes/tablets could be pressed even though a high fibre content was used (fibres are elastic and can lead to capping/breakage after pressing). This behaviour might be explained by the entrapment of salt in fibers. It enables the use of higher contents of fibers in applications. It should also be mentioned that the flow-ability is positively influenced by using the salt-fiber mass compared to pure fibres.

Consequently the present invention relates to a process for the production of a bouillon tablet comprising salt and fibers, the process comprising the steps of:.

The bouillon tablet is free from maltodextrin. The bouillon tablet is free from glucose syrup. Replacing maltodextrin with humid native starch was found to decrease undesirable texture changes such as post-hardening. Maltodextrin, and to a lesser extent glucose syrup are not a common ingredients in domestic kitchens and so may be viewed with suspicion by some consumers. In this context, glucose syrup and maltodextrin are mixtures of D-glucose units connected in chains of variable length, produced from starch by hydrolysis.

Humid native starch of an appropriate moisture content may be obtained by blending humid and non-humid starches and allowing them to equilibrate. Humid native starches are often available commercially at a lower price than the dry native starch as water needs to be removed from starch in the manufacturing process, humid native starch being effectively a part-finished ingredient.

Gum according to this invention is xanthan gum, carrageenan, locust bean gum, agar, alginates, guar gum, arabic gum, gellan or combination thereof.

The particle size Dv50 is used in the conventional sense as the median of the particle size distribution. Median values are defined as the value where half of the population reside above this point, and half resides below this point. The Dv50 is the size in micrometer that splits the volume distribution with half above and half below this diameter. The particle size distribution may be measured by laser light scattering, microscopy or microscopy combined with image analysis. For example, the particle size distribution may be measured by laser light scattering. Since the primary result from laser diffraction is a volume distribution, the Dv50 cited is the volume median.

The drying step can be carried out by any commonly known drying technique such as air drying, oven drying, drum drying, vacuum drying, bed drying, microwave-vacuum drying, infrared radiation drying or combinations thereof. The drying step does not include spray drying.

Texture Analyser test mode was set to "Compression" with pre-test speed of <NUM>/s, test speed of <NUM>/s, post-test speed of <NUM>/s, target mode of "Distance", distance of <NUM>, halt time was set to "No", way back of <NUM>, trigger type to "Auto(Force), and trigger force of <NUM> gram. Hardness is measured not in the orientation where the tablet/cube were originally pressed in Flexitab; but from the side. Hardness measurement was carried out in <NUM> replication.

In case the fiber and salts are dry-mixed (without any further processing step), the resulting mixes cannot be tableted upon compaction using our tableting system.

examples <NUM> to <NUM> were processed according to the process of example <NUM> by replacing a salt-water solution with pure water. The resulting dry mixes cannot be tableted upon compaction and remain as powder using our tableting system. This means, that fibers have been mixed with pure water only and dried again. The resulting fibers have been mixed with dry salt (no salt-water solution) and the resulting dry mixes cannot be tableted upon compaction and remain as powder using our tableting system. This shows, that a compaction can only be achieved with the process of our invention (fibers added to a water-salt solution, further mixed and afterwards dried the resulting mixes can be tableted upon compaction using our tableting system).

Different kind of fibers have been tested according to the process of example <NUM>. In case the fiber has been added to a water-salt solution, further mixed and afterwards dried the resulting mixes can be tableted upon compaction using our tableting system.

Within example <NUM> it is shown that the flow-ability of the dry salt-fiber mass has a value of <NUM> and is much higher as shown within comparison example <NUM> having only a flow-ability value of <NUM>.

The dissolution time of the tablet of example <NUM> is only <NUM> sec. This is surprising as the tablet is much harder compared to a normal bouillon tablet of approximately <NUM>-200N and a dissolution time between <NUM>-<NUM> sec.

Different fiber-salt ratios have been tested according to the process of example <NUM>.

Comparative example <NUM> shows the result if pure salt is used. Comparative example <NUM> shows the result if only fibers are mixed with pure water (without water-salt solution) dried and pressed afterwards. This shows, that a compaction can only be achieved with the process of our invention (fibers added to a water-salt solution, further mixed and afterwards dried the resulting mixes can be tableted upon compaction using our tableting system).

The minimum of ration of salt to water is <NUM>:<NUM> to obtain a saturated water-salt-solution. Examples <NUM> and <NUM> shows that higher amount of water can be used without having a significant influence on the obtained salt-fiber mass and obtained hardness. During the drying step a saturated water-salt-solution will be obtained anyway.

All bouillon powder ingredients were weighted in PG5002S balance (Mettler-Toledo, USA) and then mixed in Thermomix TM5 (Vorwerk &Co. KG, Germany). Mixing was carried out at speed setting of <NUM> for <NUM> with propeller rotation was set to reverse direction. The resulting powder was then stored in a climate chamber ICH-<NUM> (Memmert GmbH, Germany) at <NUM> with <NUM> % relative humidity with fan speed of <NUM> % for <NUM> at prior to pressing.

Water activity was measured with Hygrolab HC2-aw-USB (Rotronic AG, Switzerland) connected to PC with HW4-P-QUICK-Vx software (Rotronic AG, Switzerland). Measurement were carried out at <NUM> ±<NUM> according to AOAC <NUM>-<NUM>, Water activity of canned vegetables.

Flow-ability was measured using a Schulze Ring Shear Tester RST-<NUM>. pc according to ASTM D6467. Flow-ability measurements were carried out with pre-shear normal stress set to <NUM> Pa and shear normal stress to <NUM>, <NUM>, and <NUM> Pa.

Pressing of bouillon cube and hardness measurement was carried out as described above.

Claim 1:
A process for the production of a bouillon tablet comprising salt and fibers, the process comprising the steps of:
