Abstract
Freeze storage and pasteurization of human milk are common treatments in milk banks. Thermal treatment changes the quality of milk for preterm infants? nutrition, and the aim of this paper was to examine the nutritional profile and antioxidant potential of preterm human milk after storage and pasteurization, and also after supplementation with fortifier. The effects of storage processes were estimated on mature preterm milk of 30 breastfeeding women. Total proteins, lipids and lactose were determined after thermal processing and supplementation of mature preterm milk with fortifier. The antioxidant capacity was determined using the ferric reducing antioxidant potential method and lipid peroxidation inhibition assay. Protein concentration decreased after frozen storage and pasteurization (p<0.05). Pasteurization further reduced the lipid concentration after freezing. The ferric reducing antioxidant potential decreased after thermal treatments (p<0.05). Supplementation of mature milk with fortifier increased the concentration of proteins, lipids and lactose. Our findings demonstrated that storage and pasteurization processes affect the basic nutritional composition and antioxidant capacity of preterm human milk. In order to ensure adequate nutrition for preterm infants with preterm human milk, supplementation, especially with high concentrations of proteins and lipids, is necessary after thermal treatments.
