WebAcid phosphatase is found mostly in the skim milk phase (50–70%) and the rest is found in the cream phase associated with the MFGM. The first step in the isolation of ACP from skim milk or cream involves using an acidic ion-exchange resin, which gives about a 300-fold increase in the specific activity (IU mg −1 ) of the enzyme.
