Liquid concentrated formula The present invention is concerned with concentrated liquid nutritional products, process for the preparation thereof and methods for the treatment of cachexia, i.e. a state of serious constitutional disorder associated with malnutrition. Clinical problem Some patients need complete nutrition in the smallest volume of liquid. These patients can be cachectic patients or persons suffering from end-stage AIDS, cancer or cancer treatment, severe pulmonary diseases like COPD (chronic obstructive pulmonary disease), tuberculosis and other infection diseases or persons that experienced severe surgery or trauma like burns. Furthermore, persons suffering from disorders in the throat or mouth such as oesophageal cancer or stomatitis and persons that have problems with swallowing like dysphagic persons, require special liquid, low-volume nutrition. Also, persons just suffering from reduced appetite or loss of taste will benefit from low-volume liquid food. These groups of patients are extremely sensitive to food consistency and the organo-leptic properties of the product like viscosity, mouth feel, taste, smell, colour, etc. In addition, these groups of patients may have become sensitive to lactose or gluten which may result in allergic reactions which can be badly tolerated. The problem underlying the invention is to provide a liquid product which is attractive to the patient to consume, which has an extremely high nutrient density, and which supports nutrition and well-being in the patient groups mentioned above. Prior art Many attempts have been made to solve this problem. Liquid ready-to-drink products are currently sold that comprise up to 28 wt.% dry matter. Inclusion of more ingredients leads to precipitates and sedimentation of ingredients, which imparts nutrient intake. Concentrating liquids also increases the chance of undesired interactions between ingredients which reduces stability, especially during heating and long-term storage. Increasing the amount of dry matter also increases viscosity. These phenomena often follow non-linear kinetics and the problems quickly increase in magnitude when the concentration of ingredients is increased above 28%. Many of the commercial products that are currently available therefore have protein levels below 7.5 %. When one desires to increase the protein levels to a higher level, one replaces part of the total protein by peptides or free amino acids. This seriously decreases taste appreciation and therefore voluntary intake of the product by the patient group. Many concentrates like condensed milks suffer from an incomplete nutrient profile, too high lactose levels, sticky mouth-feel, high viscosity, extreme sweetness and a high osmotic value, which is not appreciated by the consumer and increases rapidly feelings of fullness and satiety after consumption. This makes that; the urge to consume more volume deteriorates rapidly once a small amount of the product has been consumed. Cachectic patients typically suffer from extreme weakness, which often prevents sitting in a vertical position and impairs their ability to drink the food from a carton or even to suck it from a straw. The manufacture of suitable concentrated complete nutrition is difficult The ingredients to be used must fulfil many criteria: they must be pure and not be contaminated or spoiled. They must be accepted as food-grade, and not cause allergic reactions, especially against lactose or gluten. The amounts used should provide all nutrients to fulfil nutritional requirements, such as demands for specific ammo acids, vitamins, minerals and fatty acids. Components that are deleterious to the patients such as oxidised products, or that may result in the creation of off-flavours must be avoided. Dissolving of state of the art ingredients leads to one or more of the following problems either during shelf life or during processing, especially the lieat treatment: precipitation, coagulation of protein, non-emulsifying properties, creaming, gelling or high viscosity. That is why in most prior art products the level of intact protein is typically well below 8%. Inclusion of high amounts of soluble carbohydrates decreases the rate of dissolution of minerals, proteins and other soluble components and is therefore typically adjusted to below 19 g/100 ml. Fibres, especially soluble ones, further decrease dissolution rate and may increase viscosity further. The energy density of complete liquid formulae is typically below 1.4 kcal/ml, which in most cases is a practical solution to fulfil nutritional and functional requirements. When the energy density must be higher (higher than 1.45 kcal/raole), one may use additional amounts of lipids. However, increasing the amount of lipids gives problems with homogeneity and/or thick consistencies. EP 0 747 395 describes a product for treating renal patients having an energy density of 1.6-2.25 kcal/ml and comprising free amino acids and whey protein, wherein the ratio of essential to non-essential amino acids is 2-4 : 1. By using free amino acids the amino acid composition is improved without increasing the viscosity. However the taste is not acceptable for cachectic persons or other persons which have difficulties in eating the proper volume of food. The amount of protein is about 3-4 g/100 ml product. WO 99/42001 (US 6,200,950) discloses a nutritional product which has an. energy density of 1.4-1.8 kcal/ml, a carbohydrate content (maltodextrins) of 19 g, a. protein content of 6 g and a fat content of 5.9 g per 100 ml. The protein is hydrolysed whey protein, which gives high amounts of short peptides and amino acids. Therefore, this product does not meet the requirements for patients only capable of ingesting small volumes of highly palatable nutrition. Other concentrated liquid nutritional products of the prior art contain soy protein as protein source and corn syrup as carbohydrate source in order to reach sufficient density. However, soy protein does not provide an optimum amino acid profile and has a poor taste, and corn syrup gives excessive sweetness, due to the high fructose level. Therefore, such products can only be administered as an occasional energy support rather than as a complete food. The problem to be solved according to the invention is to provide a nutritional composition suitable for feeding persons having ingestion problems, such as cachetic patients, having the following characteristics: a balanced composition allowing it to be consumed as the only food source; a liquid composition with relatively low viscosity, allowing easy intake; - a high density of at least 1.45 kcal/ml, such that less than 1 litre is sufficient for daily food requirement; a sufficient level of essential amino acids, especially lysine, methionine and cysteine; an acceptable taste, with minimum presence of free amino acids and short peptides; a relatively low osmolarity, so as to allow quick passage through the stomach; a very low lactose level, in order to prevent allergic problems and discolouring problems. Description of the invention It has now been found that a thin liquid enteral nutritional product can be produced that has desirable organoleptic properties, has a very high nutrient density, is effective and is produced without problems. The product of the invention is a liquid composition, which contains in g per* 100 ml product: Component General Preferred Most preferred Example Dry matter 30-39 31-39 33-38 36.7 Intact protein 7.8-12 8.2-11 8.5-10 9.0 Lipids 4.5-8-0 4.8-7.0 5.0-6.0 5.3 Carbohydrate 17-27 18-25 19-23 21 The liquid complete nutritional composition of the present invention is synergistic and exhibits surprising results. The product is preferably nutritionally complete, which means that all vitamins are included in a recommended dosage of at most 1500 ml per day of the composition. Also, vitamins (e.g. including folic acid, vitamins B6 and B12 and panthotendc acid) can be incorporated in an amount between 0.6 and 1.5 times the amount given in the example below. The invention also pertains to a dry (powder) or concentrated product, which, after reconstitution with water, results in the thin liquid product described above. hi one aspect, the invention provides a balanced, liquid concentrated food product having an improved protein composition. In another, independent aspect, the invention provides a balanced, liquid concentrated food product having an improved carbohydrate composition. Protein fraction: The protein fraction provides at least 7.6 g, preferably 7.8-12 g per 100 ml, corresponding to about 0.31-0.48 kcal/ml (1.30-1.59 kJ/ml). The amounts of essential amino acids fulfils nutritional requirements: typically the amount of essential amino acids (Val, Leu, He, Met, Phe, Trp, Thr, His, Lys) to non-essential amino acids (Gly, Ala, Pro, Tyr, Ser, Cys, Asn, Asp, Gin, Glu, Arg) will be in the range of 0.6-1.1, preferably 0.75-1.05, most preferably 0.85-1.0 (w/w). Furthermore, the protein fraction preferably provides at least 8.6 wt.% of lysine residues, at least 2.5 wt.% of" methionine residues and at least 0.5 wt.% of cysteine residues, more preferably at least 10 wt.% Lys, at least 2.7 wt.% Met and/or at least 1.0 wt.% Cys. The protein fraction preferably contributes 19 to 33 % of the energy content of the composition, preferably 20 to 27 energy %. The protein content is largely (typically at least 75%, preferably at least 90%) composed of intact protein only. Preferably, the amount of free amino acids is below 5 wt.%, especially below 2 wt.% of the total protein content, and preferably below 0.4 g, especially below 0.2 g per 100 ml product. Preferably, the protein is from dairy origin for at least 90 wt.%. Casein can. be a major protein component, e.g. accounting for 60-90 % of the protein. On the other hand, 10-40%, preferably 20-37 wt.%, or even 25-37 wt.%, most preferably 25-35 wt.% is whey protein. Preferably, the major part of the proteins is obtained by demineralisation of defatted (skimmed) milk. This major part is at least 70 wt.%, preferably at least 80 wt% of the protein fraction. It was found that such a protein fraction allows high conceirtrations in a complete food concentrate without excessive viscosity problems, while comTbinations of caseinate products and whey protein preparations result in high viscosities. The demineralisation is preferably performed in such a manner that at least 97°/o, especially at least 99% of lactose is removed from the milk, leaving essentially intact protein; the protein is enriched in calcium relative to sodium, potassium and other electrolytes. This can be done using extended ultrafiltration. Such demineralised milk protein are sometimes referred to as milk protein isolates. The protein fraction of the composition of the invention can also be obtained by demineralising casein in a similar way, and then optionally adding whey proteins (whey protein isolate). Other proteins, such as vegetable proteins like proteins firom lupine, maize, rice, soy, pea or potato, can also be present, although it is preferred ttiat these do not account for more than 10% (w/w), especially not more than 5%, of the protein content of the composition. Lipidfraction: The lipid fraction provides from about 41 kcal up to about 72 kcal (4.5-8.0 g) per 100 ml. It preferably accounts for 23-40% energy of the energy content of the composition, preferably from 28 to 35 en%. It is preferred that the lipid fraction contains 30-60 wt.% animal or algal fat, 40-70 wt.% vegetable fat and optionally 0-20 wt% medium-chain triglycerides (mainly C8 and CIO triglycerides; MCT). The animal fat fraction should preferably be low hi milk fat, i.e. the milk fat content of the fat fraction is below 6%, especially below 3%. In particular a mixture of corn oil, egg oil and/or camola oil and specific qualities of marine oils can be used. Egg oils, fish oils and algal oils are the preferred source of non-vegetable fats. In order to prevent formation of off-flavours and to decrease a fishy after-taste, it is recommended to select ingredients that are relatively low in docosahexaenoic acid (DHA), i.e. less than 6, preferably less than 4 wt% of DHA with respect to the lipid fraction. Marine oils containing DHA are preferably present in the product at a level of below 25% of the lipid fraction, more preferably below 15%. On the other hand, inclusion of eicosapentaenoic acid (EPAJ) is highly desirable for obtaining the maximum health effect. The EPA weight proportion of the lipid fraction is preferably between 4 and 15 %, more preferably between 8 and 13 %, leading to a daily dosage of 0.8-2.3 g, most preferably 1.2-1.9 g, when administered in a volume of 375 ml food composition. The weight ratio between EPA and DHA is advantageously at least 6:4, for example between 2:1 and 10:1. Carbohydrate fraction: The carbohydrate fraction preferably amounts to 17-27 g per 100 ml product (2.84-4.51 kJ/ml). The carbohydrate fraction comprises digestible and preferably also non-digestible carbohydrates. The digestible carbohydrate fractions provide about 17-24 g per 100 ml (0.68-1.0 kcal/ml; 2.84-4.01 kJ/mi), preferably 17.5-23.5 and especially 18-22 g/100 ml. The carbohydrate fraction preferably accounts for 38-66% of the energy content of the composition, more preferably from 40 to 60 en%, especially 45-55 en%. The composition of the carbohydrate fraction should be such that high viscosities, excessive sweetness, excessive browning (Maillard reactions) and excessive osmolarities are avoided. Acceptable viscosities and osmolarities are achieved by adjusting the average chain length (average degree of the polymerisation, DP) of the carbohydrates between 1.5 and 6, preferably between 1.8 and 4-. In order to avoid excessive sweetness, the total level of sucrose and fructose is less than 52% and preferably less than 40% of the carbohydrate fraction, especially of the digestible carbohydrate fraction. Long-chain digestible carbohydrates sucti as starch, starch fractions and mild starch hydrolysates (DP > 6, DE Furthermore, it is preferred that the reducing power of the total carbohydrate fraction is less than 40%, especially less than 30%, most preferably 25% or Less, of the reducing power of an equivalent amount by weight of glucose. The combined requirements of low viscosity and low reducing power implies that the carbohydrate fraction contains between 20 and 75 wt.%, preferably between 25 and 65 wt.% of norm-reducing digestible mono-, di- and trisaccharides, especially mono- or disaccharides, most preferably disaccharides. Suitable examples of such non-reducing sacch.arides are sucrose (although its level is preferably limited to below 35% to avoid excessive sweetness), and trehalose. The preferred amount of trehalose, optionally together with other non-reducing sugars, but excluding sucrose, is preferably 12-50, moxe preferably 18-45 wt.% of the carbohydrate fraction, more in particular 13-55, especially 20-50 wt.% of the digestible carbohydrate fraction. In particular a mixture of glucose syrups, trehalose and sucrose can be used. In addition to the energy-providing carbohydrates mentioned above, the carbohydrate fraction preferably also contains non-digestible carbohydrates (dietary fibres), in an amount of 0.5-6 g per 100 ml of the composition. The fibres include non-digestible saccharides having an average DP of 2-20, preferably 2-10. Moie preferably, these oligosaccharides do not contain substantial amounts (less than 5 wt.%) of saccharides outside these DP ranges, and are soluble. These can include e.g. fructo-oligosaccharides (FOS), trans-galacto-oligosaccharides (TOS), xylo-oligosaccharides (XOS), soy oligosaccharides, etc. Optionally also higher molar weight compounds such as inulin, cellulose, resistant starch and the like can be incorporated. The amount of insoluble fibre such as cellulose is preferably below 20 wt.% of the fibre component and/or below 0.4 g per 100 ml. The amount of thickening polysaccharides such as carrageenans, xanthans, pectins, galactomannans and other high molecular weight (DP > 50) indigestible polysaccharides is preferably low, i.e. less than 20% of the fibre composition or less than 1 g per 100 ml. Instead, hydrolysed polysaccharides such as hydrolysed pectins and galactomannans can be advantageously included. A preferred fibre component is indigestible oligosaccharides having a chain length (DP) of 2 to 10, for example Fibersol (resistant oligoglucose), in particular hydrogenated Fibersol, or a mixture of oligosaccharides having a chain- length of 2-10, such as fructo-oligosaccharides or galacto-oligosaccharides, which may also contain a small amount of higher saccharides (e.g. DP 11-20). Such oligosaccharides preferably comprise 50-90 wt. of the fibre fraction or 0.5-3 g per 100 1 of the composition. Other suitable fibre components include saccharides that have only partial digestibility or partial reducing power, for example ketose-terminated oligosaccharides such as tagatose, palatinose and trehalulose, oligodextroses of the Litesse Ultra® type, aiwi the like. The following carbohydrate composition is especially presferred: Carbohydrate component wt.% of carbohydrate fraction wt. (g) per 100 ml of food composition Broad preferred broad preferred maltodextrins (DP 2-6, DE 20-60) 30-65 35-60 5-14 7-12 sucrose 5-35 12-30 1-8 2.5-7 other non-reducing mono/di/trisaccharides, especially trehalose 15-45 20-40 3-9 4-8 lactose 0-1 0-0.5 0-0.2 0-0.1 reducing monosaccharides (e.g. glucose, fructose) 0-10 0-5 0-2.5 0-1.5 fibres 0-20 0-12 0-6 0-4 Describing the carbohydrate fraction as a function of sugar size, it comprises 0-15 wt.% (pref. 2-10 wt.%) of monosaccharides (e.g. glucose), 50-100 wt.% (pref. 60-90 wt.%) of disaccharides (e.g. maltose, sucrose, trehalose), 0-40 wt.% (pref. 10-25 wt.%) of tri-saccharides (e.g. maltotriose, kestose, raffinose), 0-30 wt_% (pref. 5-20 wt.%) of DP 4-6 oligosaccharides and 0-25 wt.% (pref. 0-15 wt.%) of highter saccharides. Further components The amount of divalent ions is 170-230 mg per 100 mtl and preferably 180-220 mg. Preferably the amount of calcium is between 155 and 185 mg/100 ml and preferably between 160 and 180 mg. The phosphorus content can be above 10 mg per g protein, with a calcium to phosphorus weight ratio between 1.0 ajnd 2.0, preferably between 1.1 and 1.7. Camitine may advantageously be present in an amount of 8-1000 mg per 100 ml, preferably 10-100 mg per 100 ml product; it may ha_ve the form of carnitine, alkyl carnitines, acyl carnitines or other carnitine derivatives. Organic acids are preferably present at a level of between 0.1 and 0.6 g per 100 ml, especially 0.25-0.5 g/lOOml. These acids include short fatty acids such as acetic acid, hydroxy acids such as lactic acid, gluconic acid, and preferably polyvalent hydroxy acids such as malic acid and citric acid. The viscosity of the liquid composition should be low, i.e. below 50 mPa.s at 20°C at a shear rate of 100 s"1, preferably between 20 and 40 mPa.s. The osmolarity of the composition is preferably between 360 and 480 mOsm, preferably between 390 and 430 mOsm. The density of the composition will be between 1.05 and 1.18 g/ml, especially between 1.08 and 1.15 g/ml. The energy density of the liquid composition is preferably at least 1.45 kcal/ml, up to about 2.25 kcal/ml (6.06 - 9.4 kJ/ml), more preferably at least 1.52, up to less than 2.0 kcal/ml (6.35 - 8.35 kJ/ml). The product of the invention is a thin liquid and it is preferred that it is packaged in small individual dosage units. Preferred package units are 5-250 ml, especially 80-200 ml, in particular 100-150 ml, or alternatively, 5-30 ml. These packaging sizes for liquid food products containing at least 1.45 kcal per ml, and preferably containing at least 7.6 g protein per 100 ml, were found to be very effective in administering sufficient: food to patients having food ingestion problems, and constitute a special embodiment of the invention. The liquid should at least contain 7.6 g or more protein per 1 00, and preferably contains one or more of the components described above, such as specific carbohydrates, specific fats, vitamins and the like. The packaging can e.g. have the form of a block-shaped carton to be emptied with a straw, a carton or plastic beaker with removable cover, or a small-sized bottle for the 80-200 ml range, and e.g. small cups for the 10-30 ml range. Another suitable packaging mode is inclusion of small volumes of liquid (e.g. 10-20 ml) in edible solid or semi-solid hulls or capsules, for example chocolate coverings (bonbon type), gelatine-like coverings etc. Preparation of the product The product can be prepared for example by first preparing a liquid protein fraction. Thus, a milk ultrafiltration retentate in dry form can be dissolved in an aqueous solution to obtain a low-viscosity liquid. Then the carbohydrates (e.g. maltodextrins, sucrose, trehalose, and optionally indigestible oligosaccharides), and water-soluble vitamins and other components are added in one or two stages, mixed, adjusted to the desired viscosity, and then the fat fraction, including fat-soluble vitamins, is added, homogenised, heat-treated and packaged. Effectivity The compositions according to the invention are suitable for any patients having problems in ingesting substantial amounts of food, such as cachexia patients. The administration of these composition lead to a higher food intake, resulting in less loss of lean body mass, improvements in well-being and less complications during the diseased state. Compliance of the product of the invention, i.e. the proportion of supplied energy to consumed energy, is improved with respect to conventional products.
