  • Patent number: 8057840
    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.

  • Publication number: 20100189843
    Abstract: A composition comprising from about 3% d.s.b. to about 35% d.s.b. of a first starch, wherein the degree of substitution (DS) of the first starch with a hydroxypropyl group is from about 0.1 to about 0.6; from about 10% d.s.b. to about 50% d.s.b. of a second starch; and from about 15% d.s.b. to about 87% d.s.b. of a flour or a meal. A method, comprising extruding a composition as described above and from about 15% total weight to about 25% total weight water at a temperature from room temperature to about 200° C., to yield an extruded composition comprising less than about 5% total weight water.

  • Publication number: 20090297690
    Abstract: A process for producing a sustained release starch product comprises (1) combining and mixing starch, hydrocolloid, and water to form a starch material, and (2) drying the starch material to form a starch product. The dried starch product optionally can be milled to the desired particle size.
