The Claim

Holder pasteurization reduces DPPH scavenging, superoxide scavenging, and ferricyanide reduction activities in donor human milk while preserving hydroxyl scavenging and iron chelation activities.

How it works
1 study reviewed
In plain English

Holder pasteurization decreases some antioxidant functions in donor human milk, such as DPPH scavenging, superoxide scavenging, and ferricyanide reduction, but does not reduce hydroxyl scavenging and iron chelation.

See the scientific wording

Holder pasteurization reduces multiple antioxidant functions in donor human milk, including DPPH scavenging, superoxide scavenging, and ferricyanide reduction, while preserving hydroxyl scavenging and iron chelation, suggesting that the process selectively impairs certain antioxidant pathways without uniformly degrading all protective components.

Why this might work

Heating milk destroys certain proteins and molecules that fight harmful radicals and reduce metals, but leaves other proteins intact that trap iron and stop it from making more radicals. This means some defenses break down, but the iron-trapping defense stays strong.

  1. Study: Loss of antioxidant function in donor human milk after holder pasteurization: a pilot study

    Pasteurizing donor milk makes some of its protective abilities weaker, like fighting certain harmful molecules, but leaves other protections just as strong. So it doesn’t ruin everything—just some parts.
