The present invention provides a process using zeolites for recovering isoflavones and removing undesired oligosaccharides from aqueous mixtures, such as soy whey and other plant processing waste products. The aqueous mixture is treated with a large pore hydrophobic zeolite, such as zeolite Beta, to remove isoflavones, followed by treatment with an ultrastabilized, hydrophobic zeolite Y, such as CBV-901 or HiSiv&#x2122; 4000, to remove the undesired oligosaccharides raffinose and stachyose. The recovered isoflavones and digestible sugars, glucose, sucrose, and fructose, are useful in food products.

Recovery of isoflavones and removal of oligosaccharides from aqueous mixtures using zeolites

The present invention relates to a process for selectively removing undesired oligosaccharides from aqueous mixtures such as plant processing waste products, including soy whey and other vegetable wheys, using an ultrastabilized large pore, hydrophobic zeolite Y. The resulting solution, which contains isoflavones and digestible sugars such as glucose, fructose and sucrose, can serve as the basis for a nutritious new product.
