Abstract

Donor human milk (DHM) is the preferred alternative for feeding infants, if maternal milk is not available. However, extensive storage and processing of DHM may negatively affect the composition. Currently safety measures predominantly consider microbiological aspects, and with the increasing demand for DHM in neonatal units due to greater survival of extremely preterm infants it is imperative to prioritise nutritional quality. This review summarises current evidence of the effects of storage and processing conditions on total fat, long-chain polyunsaturated fatty acids, lipid mediators and antioxidant content of DHM.
Based on the available evidence, it is recommended that storage time is minimised, and DHM kept in light protected bottles. Storage at 4°C should be avoided whenever possible, with storage at 80°C prior to pasteurisation being preferential. Further research is needed to evaluate the effects of long term storage at 20°C, and the impact of storage conditions on lipid mediators.
