So next time when you drink such milk your immune system triggers for the secretion of immunoglobulin E or IgE antibodies which neutralizes the protein which causes to develop signs or symptoms of milk allergy.

Whey: Whey protein exists in the liquid part of the milk which remains after the milk curdles.
Casein: Casein protein exists in the solid part of milk which curdles.
