The technical FIELD TO WHICH the INVENTION RELATES.

The present invention relates to a method of spray drying of oligosaccharides on the basis of uronic acid.

The LEVEL of TECHNOLOGY

It is known that the products of hydrolysis of viscous soluble fibers have positive effects, for example, in the prevention of diarrhea and to prevent attachment of pathogens to epithelial cells of the gastrointestinal tract, see, for example, EP1267891.

However, despite these advantages of the products of hydrolysis of viscous fiber, especially pectin, they usually do not find application in commercial products intended for oral administration to man. WO 02/42484 describes the method of obtaining the products of hydrolysis of pectin and their application.

Before you apply the products of hydrolysis of polymers of uronic acid, it is necessary to overcome several potential difficulties. For example, the oligosaccharides on the basis of uronic acids are difficult to handle, i.e. they receive in the form of aqueous solutions with low dry matter content, and hence they are prone to bacterial contamination and, thus, they are difficult to store. In addition, oligosaccharides subject to change colors, especially in the case when they are brought into contact with other carbohydrates and proteins, potentially leading to unwanted is reductum reaction Maiar (Maillard) c attendant undesirable effects on color, the smell and taste of the product.

Due to the above difficulties encountered in their use, oligosaccharides are not used or used only very sparingly in the food industry. When using the stage of food processing will be performed so as to avoid contact between the oligosaccharides on the basis of uronic acid and other components in the reactive environment, for example, by dry mixing of oligosaccharides on the basis of uronic acid. Dry mixing has additional disadvantages because it is expensive and often leads to the separation of particles by size or density during transport, giving unacceptable products.

The INVENTION

The authors of the present invention have found that spray drying of aqueous products containing oligosaccharides on the basis of uronic acid, with a degree of polymerization (DP) 2-250, gives powders with useful properties that can be appropriately used in food products.

Therefore, in one aspect, it was found that aqueous compositions which have a relatively low dry matter content with a high percentage by weight of oligosaccharides on the basis of the uronic acid may be suitably dried by spraying, powder giving products that may be appropriately used for additional processing in food. It was found that the process does not require the addition of significant quantities of the substance carrier.

In an additional aspect, it was found that an aqueous solution containing oligosaccharides on the basis of uronic acids, carbohydrates and protein may be dried by spray without unacceptable leakage reactions Maiar, and, therefore, giving a product with very useful properties, and which is ready for use in food products.

Particles of powder products contain, in addition to the oligosaccharide on the basis of uronic acids, other nutrients macronutrients such as protein and carbohydrates. Joint drying with a spray of acidic oligosaccharides and macronutrient provides a more constant nutrient profile per serving derived from the powder mass, and, thus, overcomes the problems such as the separation of the powder particles by size and/or density. Permanent nutrient profile of individual portions is of particular importance in the manufacture of baby food. Therefore, in one particular the present invention relates to a powder product with a constant nutrient profile of baby food.

In another aspect, it was found that an aqueous solution containing oligosaccharides on the basis of uronic acid and soluble dietary plaid is in, including tough (nevereverever) capable of fermentable oligosaccharides, can be dried by spray without significant reactions of Maiar, even in those cases when it is used in combination with protein.

The present invention also provides a composition obtained by the method described in this document. Due to the way the spray drying oligosaccharides in the product now better distributed through the powder in comparison with a situation where to get baby food powdered oligosaccharides are mixed in dry form. Individual particles in the powder composition, the resulting spray drying, contain a combination containing oligosaccharides on the basis of uronic acid and micronutrients macronutrients. Traditional methods of mixing, such as dry mixing, result in a powder mixture of separate particles.

Moreover, pectin and polymers algae usually dried in a cylinder dryer or drum dryer, which gives the powder product with desirable properties and characteristics. The powders of the present invention, obtained by spray-drying, containing large concentrations of oligosaccharides may differ from powders obtained by drying roller in the dryer or drum dryer, the size of their particles, for example,dried with a spray particles have an average particle size of 20-100 μm, preferably 30-80 μm. Particles of powders, dried in a cylinder dryer, typically have an average particle size of about 150 microns.
