Colostrum can be successfully heat-treated without affecting antibody levels or viscosity, but you have to do it right. Researchers at Penn State University offer these guidelines when heat-treating colostrum:

  • Use a small batch pasteurizer with adjustable temperature controls so that you can heat the colostrum at a lower temperature (140 F) than that used for waste milk.
  • Start the holding time (60 minutes is recommended) when colostrum reaches 140 F, not when you turn on the pasteurizer.
  • Agitate the colostrum to promote even heating.
  • Monitor the pasteurizer temperature to make sure the unit is operating properly.
  • Cool colostrum rapidly after pasteurization to prevent protein damage.
  • Train employees on what to do, how to do it and why it is important.
