Abstract
A composition for use as a processing aid in the concentration of whole cheese whey and in the recovery of lactose from cheese whey by a separation process followed by a concentrating process via reverse osmosis filtration or evaporation, wherein, in one embodiment, the composition includes a sodium hexametaphosphate having phosphate chain lengths of 12 to 28 in combination with tetrasodium or tetrapotassium pyrophosphate. In another embodiment, a blend of sodium hexametaphosphate is employed having a phosphate chain lengths of 12 to 14 in one instance and 21 to 28 in another instance.
