Summary: This study investigated the impact of microwave-assisted heating on the concentration of key biological compounds in donor human milk. Compared to low-temperature long-time pasteurization, microwave-assisted heating better preserved the concentration of immunoglobulins and lactoferrin, making it a promising alternative method for Human Milk Banks.

Summary: Holder pasteurization is the current recommended method for donor human milk treatment, effectively eliminating most life-threatening contaminants but reducing biological properties. Developments in novel processing methods to retain functional components of donor milk are of growing interest. A multifactorial approach and complementary assays are essential for assessing the suitability of new methods.

Summary: Donor human milk is the first alternative for preterm infants when mother's own milk is not available. Most available human milk banking guidelines recommend classical holder pasteurization to ensure safety by eliminating potential infectious microorganisms. Processing by heat treatment, however, negatively affects functionality and availability of bioactive components naturally present in human milk. Here we compared the effect of five different processing methods on the ability of human milk to induce blood plasma clotting, and found that ultraviolet-C irradiation and high-pressure processing were best at preserving this activity.

Summary: This study investigated high-pressure processing (HPP), ultraviolet-C irradiation (UV-C), and thermoultrasonication (TUS) as alternatives to thermal pasteurization (HoP) for donor human milk treatment. The results showed that HPP and UV-C may be considered as suitable alternatives to HoP, as they achieved sufficient microbial inactivation while better preserving the bioactive components of the milk.

Summary: Human milk is the best feeding option for preterm infants. When mother's milk is not available, pasteurized donor human milk is the best alternative. This study compared the microbiota of pasteurized donor human milk with the milk from mothers who delivered prematurely and assessed the effect of pasteurization on the microbiota. The results showed that pasteurized donor human milk had higher alpha diversity and a different composition compared to milk from mothers who delivered prematurely. Pasteurization also had an impact on the microbiota structure of human milk.

Summary: This study found that HTST and UV-C technologies could significantly reduce the number of bacteria in skim milk, with MF technology being the most effective in reducing bacteria. UV-C and MF were able to completely eliminate coliforms, while HTST was unaffected. The retention rates of various bioactive proteins/enzymes differed under different treatment methods, with MF-0.8 and MF-1.4 showing the best results.

Summary: This study compared the effects of raw versus pasteurized milk and colostrum versus mature milk on cellular functions associated with the gut epithelial barrier and responses to inflammatory stimuli. The results showed that all types of milk stimulated epithelial cell proliferation. However, only raw colostrum increased cell migration and interfered with the interaction between E. coli and epithelial cells. Moreover, only raw colostrum enhanced the response of epithelial and macrophage cells to lipopolysaccharide (LPS), while both raw and pasteurized milk diminished the LPS induced response in monocytes.

Summary: This study compared the effect of different techniques on the insulin concentration in donor human milk (DHM) and found that thermoultrasonication (TUS), ultraviolet-C irradiation (UV-C), and high-pressure processing (HPP) can preserve insulin in DHM. These new techniques may serve as alternatives to holder pasteurization (HoP).

Summary: Human milk is the best nutrition source for infants and contains bioactive compounds and microorganisms. Pasteurization and UV-C irradiation are both used to prevent pathogen transmission, but UV-C may be more effective in eliminating potential phages that could affect infant gut colonization. Further studies are needed to explore the impact of pasteurization methods on bacteriophage titres in human milk.

Summary: This study investigated the effect of UV-C radiation on the bacterial count of raw and pasteurized milk contaminated with Escherichia coli at different thickness levels. The results showed that the bacterial count decreased exponentially with increasing UV-C dose and that the effect of the dose was more pronounced at lower thicknesses. The statistical analysis revealed that the developed model was highly significant, with an adjusted R-squared of 0.981. Additionally, the quality and composition of the milk treated with UV-C were not affected.

Summary: A systematic study conducted from 2017 to 2020 examined the presence of B. cereus in pasteurized banked human milk (PBM), finding a significant increase in positive tests during the summer months. Bacterial contamination, with B. cereus being the most common contaminant, resulted in an annual discard rate of PBM ranging from 8.7% to 10.0%. Additionally, enterotoxin production was detected in 15% of the tested samples, and most samples had B. cereus CFU-quantities below 10 CFU/mL. These quantitative data provide insights for risk assessment in the storage and handling of PBM.

Summary: The study shows that lowering the time and temperature of pasteurization can better preserve the bioactive components of human milk and restore its antiviral activity against cytomegalovirus. This work questions the standard pasteurization method and opens the debate on whether the temperature commonly used in human milk banks should be lowered for better preservation of the biological components of the milk.

Summary: This study investigates the impact of maternal dietary intervention during lactation on the infant gut microbiome. The results show that a short-term reduced fat and sugar diet can alter the functional potential of the infant gut microbiome, but not its taxonomy. Changes in maternal protein and sugar intake are correlated with changes in the relative abundances of certain bacterial species.

Summary: Human milk provides essential elements for infant growth and development. Recent studies have found associations between the intake of human milk components and infant body composition, which may explain the reduced risk of childhood obesity among breastfed infants. However, quantifying the infant's actual intake of milk components is crucial for understanding these relationships.

Summary: Colostrum provides essential bioactive components for the infant gut microbiota colonization and preventing infectious diseases. However, substitutes are urgently needed for premature infants when colostrum is unavailable. This study aimed to design an appropriate lipid component for a colostrum substitute and evaluate its ability to reduce inflammation in intestinal cells. Analysis showed that the digestion of colostrum and the substitute mixtures had similar lipid profiles but exhibited subtle differences in self-assembly behavior. Bifidobacteria cultured on the substitute mixtures modulated the biological markers of necrotizing enterocolitis, suggesting the potential of these substitutes in reducing the characteristics associated with this disease.

Summary: There is a lack of understanding about the daily variations in hormones and macronutrients in human milk (HM) and inconsistent sample collection protocols between studies. This study investigated these variations by collecting milk samples from 22 lactating women before and after each breastfeed or expression. The results showed variations in hormone and nutrient concentrations, as well as circadian rhythms in milk volume. Standardized and rigorous sampling procedures considering both within-feed and circadian variations are necessary for a precise understanding of the impacts of these components on infant health, growth, and development.
