A recent study sought to investigate the effects of Holder Pasteurization (low-heat pasteurization) on the proteins in human breast milk. Holder Pasteurization is used by breast milk organizations that make donor milk available to mothers who for whatever reason can't breastfeed their own babies.
A multicenter study done by Italian and Dutch scientist collected breast milk from donors and placed divided samples into two groups. Samples from each donor were both frozen immediately and pasteurized using low-heat and then frozen.
All samples were then analyzed. 70% of the samples showed no detectable qualitative differences in the protein.
The conclusion of the study was that "in the majority of samples, Holder Pasteurization did not cause any modification, thereby preserving the biological activity of Human Milk proteins."
We use low-heat pasteurization in the production of the dairy proteins and colostrum in Thrīv Advanced because we believe it to be the best way to pasteurize dairy without destroying the beneficial components.
