US Patent 11248247 Methods and systems of producing oligosaccharides

The present invention in the field of oligosaccharide production provides a method of producing oligosaccharides of useful lengths without producing substantial amounts of monosaccharides and disaccharides (illustrated by FIG. 1). There is provided a method for producing an ingredient suitable for incorporation into a foodstuff, cosmetic, or nutraceutical, said ingredient comprising one or more oligosaccharides, wherein the oligosaccharides are produced in an enzymatic reaction, said enzymatic reaction comprising the step of contacting, in a solution or suspension, a polysaccharide-cleaving enzyme and a polysaccharide-containing feedstock, wherein said enzymatic reaction produces substantially no monosaccharides or disaccharides.
