Abstract: A method of processing a cheese processing waste stream generated in a cheese-making process, comprising:i) contacting a cheese processing waste stream with an anion exchange resin under conditions to allow negatively charged materials to be absorbed onto said anion exchange resin;ii) removing said anion exchange resin from said cheese processing waste stream and eluting said anion exchange resin with an aqueous solution of a lithium salt to produce an eluent;iii) concentrating said eluent to form a solid comprising a lithium salt and a lithium salt of a cheese processing waste; andiv) washing said solid with an organic solvent, dissolving said lithium salt and leaving said lithium salt of a cheese processing waste as a solid.

Abstract: A method of processing a cheese processing waste stream generated in a cheese-making process is described comprising:i) contacting a cheese processing waste stream with a solvent and extracting a sialyloligosaccharide with said solvent;ii) separating a sialyloligosaccharide containing solvent from said cheese processing waste stream; andiii) isolating a sialyloligosacchride from said sialyloligosaccharide containing solvent.
