  • Process for Producing Saccharide Oligomers
    Publication number: 20100047432
    Abstract: A process for preparing saccharide oligomers uses an aqueous feed composition that comprises at least one monosaccharide or linear saccharide oligomer, and has a solids concentration of at least about 70% by weight. The feed composition is heated to a temperature of at least about 40° C., and is contacted with at least one catalyst that accelerates the rate of cleavage or formation of glucosyl bonds, such as enzyme or acid, for a time sufficient to cause formation of non-linear saccharide oligomers. A product composition is produced that contains a higher concentration of non-linear saccharide oligomers than linear saccharide oligomers.

  • Food Products Comprising a Slowly Digestible or Digestion Resistant Carbohydrate Composition
    Publication number: 20070184177
    Abstract: 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 40° C.
