Abstract

Separation using electrophoresis of the caseinomacropeptide (CMP) liberated by the action of chymosin on k-casein, found on cheese whey was studied. Whey powder can be detected in fresh raw milk when doses of over 2% are added.
The proposed methodology does not present any interference with the detection of the caseinomacropeptide liberated in cheese whey by other peptides generated by proteolysis of psychothrophic bacterias in cooled milk.
