A novel process for the removal of phosphorous from mammalian milk, preferably bovine skim milk, has been developed. The process involves passage of the milk at an elevated temperature through a Type I or Type II macroporous or gel type strong base ion exchange material in the chloride or carbonate form. The weak base anion sites inherent to the ion exchange material have been neutralized. The ion exchange material can easily be regenerated.

A novel process for the removal of phytate from protein using ion exchange has been developed. The process involves the upflow passage of a protein slurry at an elevated temperature through a strong base anion exchanger in the chloride form. The weak base anion sites inherent to the resin have been converted to the free base form. The anion exchange material can easily be regenerated. The process can be used on-line, yields phytate removal of greater than 90%, has high (greater than 90%) protein recovery, is cost-effective, and is environmentally friendly.
