Patent

CA 2394090

The invention relates to an oligosaccharide mixture based on oligosaccharides produced from one or several animal milks and which are composed of two or more monosaccharide units. Said oligosaccharide mixture is characterized in that it com-prises at least two oligosaccharide fractions which are each composed of at least two different oligosaccharides. The invention is further cahracterized in that lactose does not pertain thereto and the total spectrum of the oligosaccharides present in the oligosac-charide mixture differs from those present in animal milk or animal milks, wherefrom the oligosaccharide fractions are extracted and that a) if said oligosaccharides are extracted from only one animal milk, the proportion of neutral oligosaccharides to acidic oligosac-charides is 90 -60: 10 - 40 weight %, or b) if said oligosaccharides are extracted from at least two animal milks, the oligosaccharides extracted from two different animal milks each make up 10 weight % of the total amount of oligosaccharides present in the oligosac-charide mixture. The oligosaccharide mixture according to the invention approximates to human milk with respect to its positive properties and in particular its anti-infective activity.

L'invention concerne un mélange à base d'oligosaccharides extraits d'un ou plusieurs laits animaux et composés d'au moins deux motifs monosaccharide. Ce mélange d'oligosaccharides est caractérisé en ce qu'il présente au moins deux fractions oligosaccharides constituées respectivement d'au moins deux oligosaccharides différents, à l'exception de la lactose libre. Il est également caractérisé en ce que le spectre total des oligosaccharides présents dans ledit mélange diffère de celui du ou des laits animaux à partir desquels ont été obtenues les fractions d'oligosaccharides. Ce mélange est en outre caractérisé en ce que a) lorsque les oligosaccharides ont été extraits d'un seul lait animal, le rapport entre les oligosaccharides neutres et les oligosaccharides acides s'élève à 90-60 :10-40 % en poids, ou b) lorsque les oligosaccharides ont été extraits d'au moins deux laits animaux, les oligosaccharides extraits d'au moins deux laits animaux différents représentent chacun au moins 10 % en poids de la totalité des oligosaccharides présents dans le mélange d'oligosaccharides. L'effet positif et en particulier l'effet anti-infectieux de ce mélange d'oligosaccharides se rapprochent de celui du lait humain.
