Definitions

  • the present invention relates to a nutritional composition, the use of a nutritional composition to promote gut comfort and a process for preparing the nutritional composition. Furthermore, the present invention relates to a method for providing nutrition and improving the digestive tract and bowel function and to a method for enhancing mucosal function.
  • EP 0 721 742 points out the occurrence of malnutrition with elderly people or patients and discloses a nutritional composition addressing this situation.
  • malnutrition may also affect perfectly healthy people, be it due to increased energy expenditure, as is the case with athletes or other sportsmen following intensive physical exercise, be it in other circumstances, such as pregnancy, for example.
  • the occurrence of malnutrition in various situations during life, in particular with elderly or ill people has thus led mainly to high calorie and high nutrient compositions.
  • the concept was to provide a maximum of energy and essential nutrients in a minimal volume to be consumed.
  • compositions of the state of the art were often problematic, especially in patients with unbalanced gut flora and with gut impairment. These compositions can cause gut pain or gut discomfort and are not always well supported.
  • an object of the invention to provide a nutritional composition to regulate gut motility and/or to improve intestinal transit, also suitable for persons suffering from diarrhoea or constipation.
  • Another object of the present invention is to provide a product that has a specific range of fibre density, which gives excellent gut-benefits, such as well-being, gut-comfort, prevents constipation and diarrhoea and results in soft stool.
  • a nutritional composition which is rich in fibre, includes different classes of dietary fibre to promote gut health and has a high energy content.
  • a composition may also be prepared, if desired, to be nutritionally complete and balanced.
  • the present invention provides a liquid or powdered and reconstitutable nutritional composition
  • a protein source a source of digestible carbohydrates and a source of dietary fibre, characterised in that it has an energy density of 1.4-1.8 kcal/ ml and dietary fibre in an amount of more than 2.5g/100ml (in each case after reconstitution if appropriate).
  • the present invention provides a method for preparing the nutritional composition according to the present invention, comprising the steps of mixing components of the composition, and, hydrating the components to provide a liquid mixture.
  • the present invention provides a method for providing nutrition and improving the digestive tract and bowel function and/or to maintaining or restoring a well-balanced gut flora comprising the step of administering to a individual the nutritional composition according to the present invention.
  • the present invention provides a method for enhancing mucosal function in a human individual, comprising the step of administering to a human individual the nutritional composition according to the present invention.
  • dietary fibre designates carbohydrates that are not digested or absorbed in the stomach and the small intestines and thus essentially arrive at the large intestine.
  • dietary fibre can be divided in soluble and insoluble fibre according to solubility in water, the standard protocol is found in L. Prosky et al., J. Assoc. Off. Anal. Chem. 71, 1017-1023 (1988).
  • typically soluble fibre are inulin, pectin, ⁇ -glucans, various gums such as gum arabic, tragacanth, mucilages, guar and locust bean gum, agar, carageenans, alginates, xanthan and the like. These ingredients are commercially available.
  • Insoluble fibre include cellulose and others, suitable sources of insoluble dietary fibres are hull fibres from legumes and grains; for example pea hull fibre, oat hull fibre, barley hull fibre, and soy hull fibre.
  • Pea outer fibre is identical to the term pea hull fibre.
  • pea inner fibre also called pea cellular walls, generally comprises (fibre only) 10-20% of cellulose, 40-50% of hemicellulose and 35-45% of pectin.
  • Pea inner fibre may be commercially obtained under the tradename Swelite® from Cosucra, for example, a product, which further comprises starch.
  • Fibre may further be classified in fermentable and non-fermentable fibre, according to its ability to serve as a substrate for the colonic bacterial flora. While fermentable fibre is usually broken down to smaller molecules, such as short chain fatty acids, non-fermentable fibre cannot or only hardly be broken down by the micro-organisms in the human colon and therefore essentially appears in stool.
  • oligosaccharides are defined as having a DP of 3 to 10, while polysaccharides cover all carbohydrates having a higher DP. Oligosaccharides may thus be a mixture of saccharides of a specific structure but of varying DP, but of which more than 50% by weight of all of the saccharides have a DP in the range of 3- 10.
  • FOS for example, are commercially obtainable in the form of such a mixture.
  • oligosaccharides examples include fructo-oligosaccharides (FOS), which may be obtained by hydrolysis of inulin or by synthesis from sucrose by action of fungal ⁇ -fructofuranosidase.
  • FOS fructo-oligosaccharides
  • Other oligosaccharides are lacto-oligosaccharides, galacto-oligosaccharides, xylo-oligosaccharides, gluco-oligosaccharides, for example.
  • the structure of a specific fibre which usually determines its denomination, depends on the kind, order and quantity of specific monosaccharide units as well as the kind of linkage between the monosaccharide units.
  • non- starch polysaccharides is generally used to clarify that carbohydrate- fibre different from starch is meant.

Description

HIGH FIBRE HIGH CALORIE LIQUID OR POWDERED NUTRITIONAL COMPOSITION
The present invention relates to a nutritional composition, the use of a nutritional composition to promote gut comfort and a process for preparing the nutritional composition. Furthermore, the present invention relates to a method for providing nutrition and improving the digestive tract and bowel function and to a method for enhancing mucosal function.
The Background Art
The risk of malnutrition is high during innumerable circumstances of life. For example, as discussed in US 6,200,950, metabolically stressed patients suffering from impairment of either digestion or absorption due to diseases affecting the gastro-intestinal tract are prone to malnutrition. Examples of such disease are functional dyspepsia, various forms of gastritis, peptic ulcers, colitis ulcerosa, neoplasms of the stomach, pancreatitis, diarrhoea, constipation, Crohn's disease- IBS, post-operative condition after gastro-intestinal surgery, just to mention a few.
Malnutrition or gastro-intestinal disorders, more generally gut-discomfort or pain may simply be the consequence of unhealthy or unbalanced nutritional behaviour. Especially, fast food is very often rich in cholesterol, has generally an unbalanced nutritional profile and can therefore lead to malnutrition.
EP 0 721 742, for example, points out the occurrence of malnutrition with elderly people or patients and discloses a nutritional composition addressing this situation.
On the other hand, trauma or surgery patients may be in need of a high calorie and nutrient nutritional products, such as disclosed in US 5,221,668.
However, malnutrition may also affect perfectly healthy people, be it due to increased energy expenditure, as is the case with athletes or other sportsmen following intensive physical exercise, be it in other circumstances, such as pregnancy, for example. The occurrence of malnutrition in various situations during life, in particular with elderly or ill people has thus led mainly to high calorie and high nutrient compositions. The concept was to provide a maximum of energy and essential nutrients in a minimal volume to be consumed.
However, consumption of compositions of the state of the art was often problematic, especially in patients with unbalanced gut flora and with gut impairment. These compositions can cause gut pain or gut discomfort and are not always well supported.
It is an object of the present invention to provide a nutritional composition, which has a high energy content and which improves the digestive tract health.
It is a further object to provide a nutritional composition, for example in the form of a nutritional supplement, which improves and maintains a well-balanced gut flora and which improves intestinal transit.
It is, in particular, an object of the invention to provide a nutritional composition to regulate gut motility and/or to improve intestinal transit, also suitable for persons suffering from diarrhoea or constipation.
It is another object of the present invention to provide a nutritional composition, which has an increased fibre content, more particularly, which comprises an optimised mixture of different classes of fibre.
It is a further objective of the present invention to provide a nutritional supplement with high fibre and high energy content and which may further comprise other essential nutrients.
Another object of the present invention is to provide a product that has a specific range of fibre density, which gives excellent gut-benefits, such as well-being, gut-comfort, prevents constipation and diarrhoea and results in soft stool.
It is a further object to provide a liquid product with a good taste, and a product that is shelf stable. Summary of the Invention
Remarkably, a nutritional composition is provided, which is rich in fibre, includes different classes of dietary fibre to promote gut health and has a high energy content. Remarkably, such a composition may also be prepared, if desired, to be nutritionally complete and balanced.
In a first aspect, the present invention provides a liquid or powdered and reconstitutable nutritional composition comprising a protein source, a source of digestible carbohydrates and a source of dietary fibre, characterised in that it has an energy density of 1.4-1.8 kcal/ ml and dietary fibre in an amount of more than 2.5g/100ml (in each case after reconstitution if appropriate).
In a second aspect, the present invention provides a method for preparing the nutritional composition according to the present invention, comprising the steps of mixing components of the composition, and, hydrating the components to provide a liquid mixture.
In a third aspect the present invention provides a method for providing nutrition and improving the digestive tract and bowel function and/or to maintaining or restoring a well-balanced gut flora comprising the step of administering to a individual the nutritional composition according to the present invention.
In a fourth aspect, the present invention provides a method for enhancing mucosal function in a human individual, comprising the step of administering to a human individual the nutritional composition according to the present invention.
Detailed Description of the Invention
In the context of the present invention, the term "dietary fibre" designates carbohydrates that are not digested or absorbed in the stomach and the small intestines and thus essentially arrive at the large intestine.
The different forms of dietary fibre are divided into classes by different parameters. Hence, dietary fibre can be divided in soluble and insoluble fibre according to solubility in water, the standard protocol is found in L. Prosky et al., J. Assoc. Off. Anal. Chem. 71, 1017-1023 (1988). Examples of typically soluble fibre are inulin, pectin, β-glucans, various gums such as gum arabic, tragacanth, mucilages, guar and locust bean gum, agar, carageenans, alginates, xanthan and the like. These ingredients are commercially available.
Insoluble fibre include cellulose and others, suitable sources of insoluble dietary fibres are hull fibres from legumes and grains; for example pea hull fibre, oat hull fibre, barley hull fibre, and soy hull fibre. Pea outer fibre is identical to the term pea hull fibre.
Often, raw materials rich in fibre comprise different sorts or classes of fibre. For example, pea inner fibre, also called pea cellular walls, generally comprises (fibre only) 10-20% of cellulose, 40-50% of hemicellulose and 35-45% of pectin. Pea inner fibre may be commercially obtained under the tradename Swelite® from Cosucra, for example, a product, which further comprises starch.
Fibre may further be classified in fermentable and non-fermentable fibre, according to its ability to serve as a substrate for the colonic bacterial flora. While fermentable fibre is usually broken down to smaller molecules, such as short chain fatty acids, non-fermentable fibre cannot or only hardly be broken down by the micro-organisms in the human colon and therefore essentially appears in stool.
Furthermore, carbohydrates and hence most of all fibre is widely classified according to degree of polymerisation (DP) of the monosacharide units constituting a single fibre-molecule. For the purpose of the present invention, oligosaccharides are defined as having a DP of 3 to 10, while polysaccharides cover all carbohydrates having a higher DP. Oligosaccharides may thus be a mixture of saccharides of a specific structure but of varying DP, but of which more than 50% by weight of all of the saccharides have a DP in the range of 3- 10. FOS, for example, are commercially obtainable in the form of such a mixture.
Examples of oligosaccharides include fructo-oligosaccharides (FOS), which may be obtained by hydrolysis of inulin or by synthesis from sucrose by action of fungal β-fructofuranosidase. Other oligosaccharides are lacto-oligosaccharides, galacto-oligosaccharides, xylo-oligosaccharides, gluco-oligosaccharides, for example.
The structure of a specific fibre, which usually determines its denomination, depends on the kind, order and quantity of specific monosaccharide units as well as the kind of linkage between the monosaccharide units.
Since also starch is not always totally degraded in the small intestines (= "resistant starch") the term "non- starch polysaccharides" is generally used to clarify that carbohydrate- fibre different from starch is meant.
The term digestible carbohydrates, in the context of the present invention, refers to sugars, starches and other carbohydrates that are broken down by enzymes in the small intestines to absorbable monosaccharides.
All percentages refer to percent by weight, unless otherwise indicated.
Preferably, the composition according to the present invention comprises different classes of fibre, and/or fibre of different structure.

Preferably, the composition according to the invention is a shelf stable, liquid and ready-to-use composition. It preferably has a shelf life of at least 4 months, preferably 5 to 13 months, more preferably 7-12 months at room temperature. If the composition is a liquid, shelf-stable composition, it is preferably shaken slightly shortly before consumption, to redistribute possibly sedimented or settled insoluble components, such as certain fibre.
If the composition is a powdered formula, it is preferably reconstituted with water, such as nutritionally safe tap water or filtered water.
The nutritional composition may conveniently have an osmolality of about 350-670 mosm/ kg H20, preferably of 500-650 mosm/ kg H20, more preferably of 570-640 mosm/ kg H20.
Preferably, the nutritional composition has an osmolarity 400-500 mosm/ L.
The nutritional composition according to the present invention is rich in fibre, that is, it comprises more than 5 g fibre per serving. It is useful to improve and maintain a well-balanced gut flora. Furthermore, it is suitable to improve intestinal transit, to alleviate constipation and/or diarrhoea. The composition according to the present invention is thus suitable to treat or prevent gut pain and to support gut comfort.
Preferably, the present invention provides a composition for use as prophylactic and/or treatment nutrition. In particular, the nutritional composition supports recovering and/or healing from disease or malnutrition.
In a further embodiment, the composition for provides nutrition and improves the digestive tract and bowel function and/or to maintains or restores a well-balanced gut flora.
In a still further embodiment, the composition according to the invention is useful for enhancing mucosal barrier function.
In another embodiment, the composition is used for promoting gut health or comfort, for example, in an elderly patient.
The nutritional composition may be produced as is conventional. Consideration may be drawn to the fact that some ingredients are more difficult to dissolve in water that others and some vitamins are susceptible to heat. For example, the fibre source, the protein source, and the lipid source may be blended, optionally passed by a kolloid mill and dissolved in water, preferably water which has been subjected to reverse osmosis, to form a liquid mixture. The temperature of the water is conveniently about 50°C to about 80°C to aid dispersal of the ingredients. Commercially available liquefiers may be used to form the liquid mixture. Preferably, pH of the liquid mixture is adjusted to about 6.3 to 7 with food grade hydroxids.
If used, the emulsifiers may be included in the blend. The vitamins and minerals may be added at this point but are usually added later to avoid thermal degradation. Emulsifiers and the like may be dissolved into the lipid source prior to blending. Preferably, a food grade emulsifier from a vegetable source is used. An example for a commercially obtainable food grade emulsifier is Cutina GMS V (Cognis, in France).
After preparation of a liquid mixture, heating may be stopped or the mixture may be cooled and further ingredients may be added, for example digestible carbohydrates that are easily dissolvable, such as sucrose and maltodextrins with DE of 15-25. Other easily dissolvable ingredients include, for example, oligosaccharides, vitamins, minerals, flavourings and colorants.
Preferably, pH is again adjusted at a temperature of 15-20°C to about 6.9-7.
The liquid mixture may then be thermally treated to reduce bacterial loads. For example, the liquid mixture may be rapidly heated to a temperature in the range of about 80°C to about 110°C for about 5 seconds to about 5 minutes. This may be carried out by steam injection or by heat exchanger; for example a plate heat exchanger.
In case that a liquid, shelf-stable composition is prepared, an ultra heat treatment (UHT)-treatment is preferably conducted after pre-heating to 50-85°C. For example, an indirect UHT treatment may be conducted at 140-155°C for 5-8s, in a tube heat exchanger, for example.
The liquid mixture may then be cooled to about 60°C to about 85°C; for example by flash cooling. The liquid mixture is then homogenised; for example in two stages at about 100 - 200 bars in the first stage and about 20 - 80 bars in the second stage.
For a product in liquid form, the homogenised mixture is preferably aseptically filled into suitable containers. Aseptic filling of the containers may be carried out by cooling the liquid mixture, for example in an aseptic storage tank, to a temperature of about 18 to 30°C. The homogenised mixture may then be filled into containers, for example in an N2-atmosphere. Suitable apparatus for carrying out aseptic filling of this nature is commercially available.
In case a powdered, reconstitutable formula is produced, the homogenised mixture may then be further cooled to add any heat sensitive components; such as vitamins and minerals. The pH and solids content of the homogenised mixture is conveniently standardised at this point. For a product in powder form, the homogenised mixture is dried to powder; for example by spray drying. Conventional procedures may be used.
Accordingly, the process according to the present invention preferably comprises the steps of - mixing components of the composition, and, hydrating the components to provide a liquid mixture.
Furthermore, the process preferably comprises the steps of heat treating and homogenising the liquid mixture, and, in case of a liquid composition, aseptically filling the composition, or, in case of a powdered and reconstitutable composition, drying, for example spray- or roller drying the liquid mixture to obtain the composition according to the present invention.
