A food product comprises an oligosaccharide composition that is digestion resistant or slowly digestible. The oligosaccharide composition can be produced by a process that comprises producing an aqueous composition that comprises at least one oligosaccharide and at least one monosaccharide by saccharification of starch, membrane filtering the aqueous composition to form a monosaccharide-rich stream and an oligosaccharide-rich stream, and recovering the oligosaccharide-rich stream. Alternatively, the oligosaccharide composition can be produced by a process that comprises heating an aqueous feed composition that comprises at least one monosaccharide or linear saccharide oligomer, and that has a solids concentration of at least about 70 % by weight, to a temperature of at least about 4O °C, and contacting the feed composition with at least one catalyst that accelerates the rate of cleavage or formation of glucosyl bonds for a time sufficient to cause formation of non--linear saccharide oligomers, wherein a product composition is produced that contains a higher concentration of non-linear saccharide oligomers than linear saccharide oligomers.

L'invention porte sur un produit alimentaire qui comporte une composition d'oligosaccharides qui est résistante à la digestion ou lentement digestible. La composition d'oligosaccharides peut être obtenue par un procédé qui comporte la production d'une composition aqueuse qui comporte au moins un oligosaccharide et au moins un monosaccharide par la saccharification d'amidon, la filtration sur membrane de la composition aqueuse pour former un courant riche en monosaccharides et un courant riche en oligosaccharides et la récupération du courant riche en oligosaccharides. En variante, la composition d'oligosaccharides peut être obtenue par un procédé qui comporte le chauffage d'une composition aqueuse alimentaire qui comporte au moins un monosaccharide ou un oligomère saccharide linéaire et qui présente une concentration en matières solides d'au moins environ 70 % en poids, à une température d'au moins environ 40 °C, et la mise en contact de la composition alimentaire avec au moins un catalyseur qui accélère la vitesse de clivage ou de génération de liaisons glucosyles pendant un laps de temps suffisant pour provoquer la génération d'oligomères saccharides non linéaires, une composition de produit alimentaire étant obtenue qui contient une concentration supérieure d'oligomères saccharides non linéaires par rapport aux oligomères saccharides linéaires.
