Myth No. 3
"Pasteurization inactivates enzymes that kill pathogens, including lactoferrin, xanthine oxidase, lactoperoxidase, lysozyme and nisin."
No, it doesn't.
- Xanthine oxidase (XO) does not kill pathogens and is not destroyed by pasteurization.
- XO is thought to play a role in human nutrition and health and is a major component of the milk fat globule membrane (MFGM).
- XO has survived a laboratory heating of milk to 75C x 15s, which exceeds minimum HTST conditions.
