45. Myth No. 2(b) - See text below

Myth No. 2(b)

"Pasteurization inactivates lactoferrin."

No, it doesn't.

  • The thermal behavior of lactoferrin is dependent upon the iron status of the protein.
  • Paulsson et al (1993) JDS 76:3711-3720 determined that "unheated and pasteurized bLf preparations showed similar antibacterial properties and caused an effective metabolic inhibition with a moderate bacteriostasis".
  • They also stated that "pasteurization seems to be the method of choice (when making a lactoferrin product) because it did not alter either the bacterial interactive capacity or the antibacterial activity of bLf".
