Abstract:
1. A method for selectively removing the oligosaccharides raffinose and stachyose from an aqueous mixture comprising said oligosaccharides raffinose and stachyose, and digestible sugars, the method comprising the steps of: (a) contacting the aqueous mixture with an ultrastabilized hydrophobic zeolite Y having a Si/Al ratio of about 10 to about 45, whereby at least a portion of said oligosaccharides bind to said ultrastabilized hydrophobic zeolite and is selectively removed from the aqueous mixture, thereby forming a treated aqueous mixture having an increased proportion of the digestible sugars relative to the oligosaccharides; (b) separating the ultrastabilized hydrophobic zeolite Y from the treated aqueous mixture; and (c) recovering the treated aqueous mixture.
