Definitions

• the invention relates to a food composition derived from ass's milk, its use in the feeding of weak and/or sensitive subjects, such as premature babies, convalescent subjects and/or the elderly.
• the invention also relates to a method for manufacturing such a composition and to a method for the administration thereof.
• the feeding of premature babies represents a topic of vast research in the fields of medicine and neonatal feeding.
• the complexity in the feeding of premature babies is connected with several aspects that will affect the baby's health and quality of life in the short and long term. Therefore, qualitatively and quantitatively inappropriate neonatal feeding will result in nutritional deficiencies in the short run and postnatal growth deficiencies, for example neurocognitive impairment, in the long run.
• premature babies have low energy supplies, a high metabolic activity, a higher protein turnover, greater glucose and lipid requirements, an inadequacy of the sucking and swallowing reflexes, a diminished gastric capacity, a restricted production of digestive enzymes and growth factors, a decreased bowel peristaltic activity, a high incidence of hypoxaemia and sepsis.
• a possible and frequent predisposition to develop food allergies must be added to these aspects.
• compositions to be used as a breast milk supplement are known and commercially available. These fortifiers comprise variable amounts of proteins, carbohydrates, calcium, phosphorous, oligominerals, vitamins, fats and electrolytes.
• Such fortifiers are often added with protein supplements in variable amounts depending on the baby's needs.
• Both of the currently commercially available products, the fortifier and the protein supplement are obtained by processing cow's milk with the addition of synthetic and plant components, even though analogous products derived from human milk are known, but these are too expensive to be put on the market.
• Cow's milk has a nutritional composition, and particularly a protein composition, very different from that of human milk, especially from the qualitative point of view.
• cow's milk and the components derived therefrom often may be unsuitable for the feeding of premature babies as they may cause sensitization phenomena, which are precursors of allergies and intolerances.
• the fortifiers that are presently on the market are formulated as a combination of the required nutrients (proteins, carbohydrates, calcium, phosphate, vitamins and traces of oligoelements) and may be deficient in specific biological activities and in a few essential nutritional elements.
• a further object of the present invention is to provide a composition to be used as a breast milk supplement in the feeding of premature babies, which is obtainable by the method of the invention.
• Another object of the present invention is to provide a composition to be used as food or as a food supplement for subjects who need a major energy intake.
• a further object of the present invention is to provide a food composition to be used as food or as a food supplement for weak, delicate or convalescent subjects who need a particularly fortifying energy intake.
• Another object of the present invention is to provide a food composition to be used as food or as a food supplement for the elderly.
• composition of the invention which overcomes the limits of the present state of the art and exhibits excellent characteristics of tolerability in premature babies and an ideal nutritional intake.
• the present invention relates to a food composition characterized by being derived from ass's milk, which may be used in the feeding of premature babies or in the feeding of particularly sensitive or weak subjects.

• premature babies refers to babies with a body weight of 1500 g or less and/or those with a gestational age of less than 32 weeks.
• composition refers to denote a mixture of nutritional components derived from the processing of ass's milk.
• the composition comprises at least: 20-50 g of proteins, 0.1-25 g of lipids, 3.0-20 g of carbohydrates, 1.4-1.6 g of calcium, and 0.9-1.1 of phosphorous for 100 g of the composition.
• the composition comprises at least 30- 45 g of proteins, 0.5-21 g of lipids, 5-18 g of carbohydrates, 1.5 g of calcium, and 1 g of phosphorous for 100 g of the composition.
• the composition comprises approximately 35 g of proteins, 7 g of carbohydrates, 14 g of lipids, 1.5 g of calcium, and 1 g of phosphorous for 100 g of the concentrated multi-component.
• the amount of the components in the composition of the invention refers to the percentages of the components for 100 g of the composition in the form of a powder, preferably a lyophilized powder.
• the composition may include the addition of a concentrated multi-component, again derived from ass's milk.
• the said concentrated multi-component comprises at least 70-90 g of proteins, 0.1-5.0 g of lipids, 2.0-10 g of carbohydrates, 0.0-1.5 g of calcium and 0.0-0.8 g of phosphorous, for 100 g of the concentrated multi-component.
• the said concentrated multi-component comprises at least 75-88 g of proteins, 0.3-4.8 g of lipids, 2.8-8.7 g of carbohydrates, 0.5-1.2 g of calcium and 0.3-0.65 g of phosphorous, for 100 g of the concentrated multi-component.
• the said concentrated multi-component comprises approximately 80 g of proteins, 6 g of carbohydrates, ⁇ 2 g of lipids, 1 g of calcium and 0.4 g of phosphorous, for 100 g of the concentrated multi-component.
• the characteristics of the proteins, the lipids and the carbohydrates in the composition and in the concentrated multi-component are described in the following and form part of the invention.
• the above-described concentrated multi-component is a further aspect of the present invention and may be added, depending on the needs, to the composition of the invention.
• the subject-matter of the invention is the composition including the addition of the concentrated multi-component.
• composition optionally with the addition of the concentrated multi-component, both being derived from ass's milk, overcomes the limits of the present state of the art and gives significant advantages owing to its qualitative composition that is decidedly different from the commercially available fortifiers.
• composition and the concentrated multi-component, subject-matter of the present invention unlike all the fortifiers based on cow's milk, comprise all the components of the milk from which they derive, simply concentrated by ultrafiltration, thereby retaining all the biological functions typical of whole milk.
• the marketed products are indeed artificial mixtures of individual ingredients of animal (proteins, which often are hydrolyzed) and plant (fats and carbohydrates) origin, which often require the addition of an emulsifier for their reconstitution and therefore have no enzymatic activity.
• caseins and whole seroproteins are present in the protein fraction of the ass's milk- derived composition and concentrated multi-component.
• the caseins included comprise: ass's a-sl-casein, ass's a-s2-casein, ass's ⁇ -casein, ass's k-casein.
• the said proteins exhibit a higher homology with the corresponding human milk proteins, unlike those of cow's milk contained in the products that are available now.
• the seroproteic fraction of the composition and concentrated multi-component comprises high amounts of ass's lactoferrin, lysozyme and lactoperoxidase, a-lactalbumin and ⁇ -lactoglobulin.
• the said seroproteins are only present in traces in the commercially available fortifiers derived from cow's milk.
• compositions and the concentrated multi-component according to the present invention are different from the marketed products also in the lipid fraction.
• the lipid fraction is not always present in the currently marketed fortifiers and, when present, it is often of plant origin, such as for instance safflower oil, soybean oil, coconut oil, oils that are poorly tolerated by premature babies.
• the ass's milk-derived composition and concentrated multi-component have a high ratio of PUFAs (18% of total fats), 8% of which are n-3 PUFAs, the beneficial nutritional properties of which are known. Approximately 90% of the PUFA content is represented by the n-3 and n-6 series of fatty acid precursors.
• compositions either alone or added with the concentrated multi- component, are also found in the carbohydrate fraction.
• the carbohydrates contained in the currently marketed fortifiers predominantly consist of plant-derived maltodextrins, polysaccharides obtained through enzymatic hydrolysis of corn starch, corn or rice syrup.
• the said carbohydrates are highly unbearable and poorly digestible and assimilable by premature babies because of the purification processes to which they are subjected.
• the composition and the concentrated multi-component of the present invention contain lactose as the main carbohydrate source, which is also the main sugar in human milk.
• composition optionally with the addition of the concentrated multi-component, according to the invention, besides representing an appropriate source of all the nutritional components required for the feeding of premature babies, including all the essential amino acids, also guarantees an antibacterial action thanks to the high amount of lysozyme.
• composition of the invention although it has been essentially conceived for the feeding of premature babies, may also be successfully used in the feeding of subjects who need a major intake of components that are fortifying and beneficial for the body, such as weak, delicate or convalescent subjects and/or the elderly, whether they are human beings or animals.
• a further subject-matter of the present invention is a method for the manufacturing of the said ass's milk-derived composition and concentrated multi-component.
• the method according to the invention comprises the following steps:
• step b) cooling the ass's milk from step a) to a temperature between 22°C and 45°C;
• step b) ultrafiltrating the ass's milk from step b) on membranes with a molecular cut off between 5KDa and 50KDa until a product with a protein concentration between 20% and 90% is obtained;
• step d) heating the product from step c) to a temperature between 62°C and 75°C;
• the ass's milk from step a) is selected from whole ass's milk or skimmed ass's milk, depending on the desired final protein content in the composition.
• step c when it is desired to obtain the composition, the procedure will be continued until a protein concentration between 20 and 50% is obtained, whereas when it is desired to obtain the concentrated multi-component, the procedure will be continued until a protein concentration between 70% and 90% is obtained.
• step e) for instance it is possible to cool down the product from step d) at -20°C and freeze-dry it or, alternatively, to cool down the product from step d) to room temperature and package it in a liquid form.
