Overview

This series explains donor human milk banking as a whole-pathway judgment: donor support and milk variability come before processing, while screening, hygiene, cold-chain control, pooling, treatment, testing and traceability jointly shape safety and access. Holder pasteurization reduces many microbial hazards but changes selected heat-sensitive biology, so molecular findings must be kept separate from functional and clinical claims. HTST, HPP and freeze-drying offer promising preservation signals, yet their broader safety, outcome evidence, operational readiness and equity remain conditional. The result is a disciplined way to compare methods without treating safer milk as unchanged or laboratory preservation as proven clinical superiority.

Learning outcomes
  • Donor-milk safety is a chain of controls; no single temperature substitutes for screening, hygiene, cold storage, testing and traceability.
  • Holder pasteurization at 62.5 °C for 30 minutes reduces many microbial hazards but is not sterilization and alters selected heat-sensitive components.
  • Processing effects are component-specific: immune proteins and enzymes are sensitive, while total HMOs and many trace elements appear relatively stable; lipid findings vary.
  • HTST, HPP and freeze-drying show preservation signals, but adoption requires safety validation, clinical relevance, feasible operations and equitable access.

FAQ

Why is donor human milk banked if mother’s own milk is preferred?

Donor human milk is banked as a bridge for preterm or low-birthweight infants when mother’s own milk is unavailable or insufficient; it does not replace breastfeeding.

Does Holder pasteurization sterilize donor human milk?

No. Holder pasteurization at 62.5 °C for 30 minutes reduces many bacterial and viral hazards, but Bacillus spores can survive and post-treatment testing remains needed.

What does processing change in donor human milk?

Processing changes components unevenly: Holder pasteurization is associated with losses in selected immune proteins and enzymes, while total HMOs and many trace elements appear relatively stable; lipid findings vary.

Are HTST or HPP better than Holder pasteurization?

No universal answer is established: cited studies report better preservation of selected components with HTST or HPP, but clinical superiority and system readiness remain unproven.
