New alternatives to holder pasteurization in processing donor milk in human milk banks. Front Nutr 2024; 11:1409381. [PMID: 38988859 PMCID: PMC11234892 DOI: 10.3389/fnut.2024.1409381] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2024] [Accepted: 05/13/2024] [Indexed: 07/12/2024] Open
Abstract
Infectious and toxicological risks are the main potential hazards that operators of Human Milk Banks (HMBs) encounter and must eliminate. HMBs are trying to implement procedures that allow to manage and sanitize human milk without altering significantly its nutritional and biologically protective components, obtaining a product characterized by a valid balance between safety and biological quality. The history of human milk processing is linked to the origins of HMBs themselves. And although other forms of sterilization were used originally, pasteurization soon became the recognized most effective means for sanitizing milk: all the milk that arrives at the HMB must be pasteurized. Holder pasteurization (HoP) is the most used methodology, and it is performed using low temperature and long time (+62.5°C for 30 min). With HoP some bioactive milk components are lost to varying degrees, but many other precious bioactive compounds are completely or partially preserved. To improve the quality of human milk processed by HMBs, maintaining in the meantime the same microbiological safety offered by HoP, new technologies are under evaluation. At present, High-Temperature Short-Time pasteurization (HTST) and High-Pressure Processing are the most studied methodologies. HTST is already utilized in some HMBs for daily practical activity and for research purposes. They seem to be superior to HoP for a better preservation of some nutritional and biologically protective components. Freeze-drying or lyophilization may have advantages for room temperature storage and transportation. The aim of this study is to evaluate the advancement regarding the processing of DHM with a literature search from 2019 to 2022. The effects of the new technologies on safety and quality of human milk are presented and discussed. The new technologies should assure microbiological safety of the final product at least at the same level as optimized HoP, with an improved preservation of the nutritional and bioactive components of raw human milk.

Abstract
Freeze-drying (FD), or lyophilization, is commonly used to preserve foods. FD offers potential to create a human milk-derived human milk fortifier, and an alternative to freeze-storing human milk. However, processing human milk is known to affect its components. This scoping review explores the effect of FD on the; macronutrient, micronutrient, vitamin, bioactive components, microbes and anti-microbial factors in human milk, and studies where lyophilized human milk has been given to newborn infants. 48 articles were identified after full text review. FD human milk reduces the fat globule size and as well as the quantity of enzymes, vitamin C and immunoglobulin. Common serum electrolyte disturbances have been reported when preterm infants' are fed FD human milk however it appears a promising method to avoid exposure of preterm infants' to cows' milk. Due to limited data, further studies exploring the safety and efficacy of FD human milk in preterm infants are needed.

Abstract
Human milk banks pasteurize and freeze the milk in order to conserve it, but thawing and prolonged storage cause loss of nutritional components. The aim of this work was to evaluate the effect of pasteurization, high hydrostatic pressures, UV radiation, and spray drying in human milk packed and stored at 25 to 40°C by a period of 14 weeks, using an accelerated shelf life method with Arrhenius model. Effectiveness of packaging, microbiological viability, and deterioration of carbohydrates, lipids, and proteins was evaluated. The results showed that proteins and carbohydrates in powdered human milk with different treatments did not show significant changes during storage at 25 to 40°C and without the growth of microorganisms. However, 33.3% deterioration of lipid oxidation was observed up at 40°C. We predict with the applied model that, at 18°C, the human milk powder will be preserved for approximately one year without significant changes in its composition.

Combination of High-Pressure Processing and Freeze-Drying as the Most Effective Techniques in Maintaining Biological Values and Microbiological Safety of Donor Milk. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18042147. [PMID: 33671763 PMCID: PMC7926441 DOI: 10.3390/ijerph18042147] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Revised: 02/02/2021] [Accepted: 02/17/2021] [Indexed: 12/23/2022]
Abstract
BACKGROUND Human milk banks have a pivotal role in provide optimal food for those infants who are not fully breastfeed, by allowing human milk from donors to be collected, processed and appropriately distributed. Donor human milk (DHM) is usually preserved by Holder pasteurization, considered to be the gold standard to ensure the microbiology safety and nutritional value of milk. However, as stated by the European Milk Banking Association (EMBA) there is a need to implement the improvement of the operating procedure of human milk banks including preserving and storing techniques. AIM The purpose of this study was to assess the effectiveness and safety of the selected new combination of methods for preserving donor human milk in comparison with thermal treatment (Holder pasteurization). METHODS We assessed (1) the concentration of bioactive components (insulin, adiponectin, leptin, activity of pancreatic lipase, and hepatocyte growth factor) and (2) microbiological safety in raw and pasteurized, high-pressure processed and lyophilization human breast milk. RESULTS The combination of two techniques, high-pressure processing and freeze-drying, showed the best potential for preserving the nutritional value of human milk and were evaluated for microbiological safety. Microbiological safety assessment excluded the possibility of using freeze-drying alone for human milk sample preservation. However, it can be used as a method for long-term storage of milk samples, which have previously been preserved via other processes. CONCLUSION The results show that high-pressure treatment is the best method for preservation that ensures microbiological safety and biological activity but subsequent freeze-drying allowed long-term storage without loss of properties.

Abstract
BACKGROUND Neonatal infections with Cronobacter sakazakii have recently been associated with the consumption of expressed human milk. STUDY AIMS (1) To evaluate whether human milk has antimicrobial capacity against C. sakazakii and (2) to determine the stability of its capacity when it is subjected to various treatments. METHODS The antimicrobial capacity of human milk against C. sakazakii was evaluated using an observational, cross-sectional, comparative design. Mature human milk samples (N = 29) were subjected to different treatments. After incubation at 37°C for 72 hr, samples were compared with fresh milk on the stability of their antimicrobial capacity. Two-way analysis of variance (ANOVA) was performed. RESULTS In fresh milk, counts of C. sakazakii were reduced by 47.26% (SD = 6.74) compared to controls. In treated milk, reductions were: refrigeration at 4°C for 72 hr (M = 33.84, SD = 13.84), freezing at -20°C for 1, 2, and 3 months (M = 40.31, SD = 9.10; M = 35.96, SD = 9.39; M = 26.20, SD = 13.55, respectively), Holder pasteurization (M = 23.56, SD = 15.61), and human milk bank treatment with (M = 14.37, SD = 18.02) and without bovine fortifier (M = 3.70, SD = 23.83). There were significant differences (p < .05) between fresh and treated milk. CONCLUSIONS Human milk has antimicrobial capacity against C. sakazakii. However, its capacity is negatively influenced by common preservation and hygienization methods. Milk should be stored refrigerated for a maximum of 72 hr or frozen for a short period of time.

Abstract
Nitric oxide (NO) plays a role in many biological mechanisms. The amounts of physiologically produced NO are associated with the concentrations of its metabolites nitrate and nitrite. This study investigated whether there is any association between the concentrations of NO metabolites nitrate, nitrite, and nitrosylated species (RXNO) in mature breast milk, saliva, and plasma in healthy lactating women (N = 30). We hypothesized that the NO metabolites concentrations in plasma are associated with those found in saliva and in breast milk. NO metabolites concentrations were measured using chemiluminensce-based assays. Nitrate concentrations in breast milk are twice as much as plasma concentrations, whereas nitrate concentrations in saliva are about eightfold higher (both P < 0.001). Similar differences were found when nitrite concentrations were taken into consideration. RXNO concentrations in breast milk were negligible, and RXNO concentrations in saliva were approximately sixfold higher than those found in plasma samples (P < 0.0001). Nitrate concentrations in plasma are associated with nitrate concentrations in saliva (rs = 0.474, P = 0.004). However, no significant association was found between nitrate concentrations in breast milk and in plasma (P > 0.05). Our results show a significant association between nitrate concentrations in plasma with those found in saliva, whereas all other relationships were not significant. In conclusion, this report shows for the first time that the physiological concentrations of NO metabolites in human breast milk are probably independent of circulating NO metabolites concentrations and may depend mostly on endogenous NO synthesis in the breast. These findings may have clinical implications for newborns and lactating women.

Abstract
INTRODUCTION There is growing interest in the possibility of measuring the macronutrient content of human milk. Several studies that intend to validate commercially available human milk analyzers have been published with inconsistent results. This review will focus on currently available, verified methodologies for analyzing macronutrients in human milk. AREAS COVERED A literature search was conducted in the PubMed database. Five milk analyzers were chosen to be included in this review: MIRIS (Uppsala, Sweden) (seven articles found), Calais (Cleveland, United States) (four articles), SpectraStar (Brookfield, United States) (four articles), MilkoScan (Hillerdo, Denmark) (two articles), and Delta LactoScope (Stockholm, Sweden) (one article). The following information was extracted from published manuscripts: measuring device, sample preparation, purpose of the study, type of macronutrients studied, results, and conclusions. EXPERT OPINION Infrared spectroscopy can be an accurate and reliable technology for assessing the macronutrient content of human milk, specifically crude protein, and total fat. However, an optimal handling of samples, the development of standardized quality-control protocols, and an improvement in calibration procedures are required before the full implementation of infrared technology in neonatal units.

Abstract
Preterm and low birth weight infants require specific nutrition to overcome the accumulated growth deficit, and to prevent morbidities related to postnatal growth failure. In order to guarantee an adequate nutrient-intake, mother’s own milk, when available, or donor human milk, are usually fortified with additional nutrients, in particular proteins. Fortification with processed ingredients may result in additional intake in oxidative compounds, deriving from extensive heat treatments, that are applied during processing. The aim of the present work was to compare the in vitro antioxidant activity and oxidative compound content conveyed by different preterm infant foods and fortifiers, namely raw and pasteurized human milk, two different preterm infant formulas, three bovine milk-based fortifiers and two experimental donkey milk-based fortifiers. Univariate and multivariate statistical analyses revealed significant differences between the different products. The use of human milk minimizes the intake of dietary oxidative compound in comparison to infant formulas, irrespective of pasteurization or fortification, especially as far as malondialdehyde content is concerned. The addition of fortifiers to human milk increases its antioxidant capacity, and the choice of the protein source (hydrolysed vs. whole proteins) differently impacted the resulting total antioxidant capacity of the diet.

Abstract
Purpose: Human milk (HM) proteins are known as important factors in growing and development of neonates. For longer and easier storage of HM, freeze-drying is suggested as one of the promising methods for HM banks. However, the effects of freeze-drying on HM proteins were not evaluated yet. The purpose of this study is to analyze and compare proteomic data before and after the freeze-drying.Material and methods: Totally nine fresh HM samples were collected from three healthy mothers at 15 and 60 days of lactation period. The samples were freeze-dried and the proteomic analysis was performed by shotgun proteomic method with mass spectrometry. The results were compared between samples of different lactation periods, and before and after the freeze-drying using Wilcoxon signed-rank test for paired comparisons. Moreover, the functional grouping and analysis were performed for the detected proteins by bioinformatics analysis.Results: Totally, 245 proteins were detected in the HM samples. The expression of proteins was not affected by both of the different lactation periods and the freeze-drying status (P>.050). Moreover, the functional analysis of proteomic data revealed no significant difference between both groups as well.Conclusion: HM proteins were found not to be significantly affected by the lactation periods (15 and 60 days) and freeze-drying status. As significant changes of HM proteins were not found after the freeze-drying, we hope that the present study would support introducing freeze-drying in the HM banks. However, the number of samples was quite small to provide strong evidence. Moreover, the evaluation of the safe storage length in the view of infectious agents and the composition changes after freeze-drying is warranted in the further study.

Abstract
BACKGROUND Donor human milk is considered the next best nutrition following mother's own milk to prevent neonatal infection and necrotizing enterocolitis in preterm infants who are admitted at neonatal intensive care unit. However, donor milk biofunctionalities after preparative processes have rarely been documented. OBJECTIVE To evaluate biofunctionalities preserved in donor milk after preparative processes by cell-based assays. MATERIALS AND METHODS Ten pools of donor milk were produced from 40 independent specimens. After preparative processes, including bacterial elimination methods (holder pasteurization and cold-sterilization microfiltration) and storage conditions (-20°C freezing storage and lyophilization) with varied duration of storage (0, 3, and 6, months), donor milk biofunctionalities were examined by fetal intestinal cell growth and antimicrobial assays. RESULTS At baseline, raw donor milk exhibited 193.1% ± 12.3% of fetal intestinal cell growth and 42.4% ± 11.8% of antimicrobial activities against Escherichia coli. After bacteria eliminating processes, growth promoting activity was better preserved in pasteurized donor milk than microfiltrated donor milk (169.5% ± 14.3% versus 146.0% ± 11.8%, respectively; p < 0.005), whereas antimicrobial activity showed no difference between groups (38.3% ± 14.1% versus 53.7% ± 17.3%, respectively; p = 0.499). The pasteurized donor milk was further examined for the effects of storage conditions at 3 and 6 months. Freezing storage, but not lyophilization, could preserve higher growth-promoting activity during 6 months of storage (163.0% ± 9.4% versus 72.8% ± 6.2%, respectively; p < 0.005). Nonetheless, antimicrobial activity was lost at 6 months, regardless of the storage methods. CONCLUSIONS This study revealed that fetal intestinal cell growth and antimicrobial assays could be applied to measure donor milk biofunctionalities and support the utilization of donor milk within 3 months after preparative processes.

Abstract
It has recently been discovered that breastmilk is not sterile, but contains a vast array of microbes, known collectively as the breastmilk microbiome. The breastmilk microbiome field is in its infancy, but over the last decade, our understanding of the microbial communities that inhabit the human body has increased exponentially, due in large part to novel next-generation sequencing technologies. These culture-independent, high-throughput molecular technologies have allowed biologists to investigate the entirety of microbiota present in breastmilk, which was previously poorly known. These approaches are novel and the methodologies surrounding the exploration of the breastmilk microbiota remain in flux. The objectives of this chapter are to outline what is known thus far and detail the optimal methods and strategies to conducting a breastmilk microbiome study from subject recruitment and milk collection to DNA extraction, high-throughput sequencing and bioinformatics analyses.

Abstract
BACKGROUND Inhibiting changes to bacteria in human milk between sample collection and analysis is necessary for unbiased characterization of the milk microbiome. Although cold storage is considered optimal, alternative preservation is sometimes necessary. RESEARCH AIM/QUESTION The objective of this study was to compare the effectiveness of several commercially-available preservatives with regard to maintaining bacterial DNA in human milk for delayed microbiome analysis. Specifically, we compared Life Technologies' RNAlater® stabilization solution, Biomatrica's DNAgard® Saliva, Advanced Instruments' Broad Spectrum Microtabs II™, and Norgen Biotek Corporation's Milk DNA Preservation and Isolation Kit. METHODS Aliquots of 8 pools of human milk were treated with each preservative. DNA was extracted immediately and at 1, 2, 4, and 6wk, during which time milk was held at 37°C. The V1-V3 region of the bacterial 16S rRNA gene was amplified and sequenced. Changes in bacterial community structure and diversity over time were evaluated. RESULTS Comparable to other studies, the most abundant genera were Streptococcus (33.3%), Staphylococcus (14.0%), Dyella (6.3%), Pseudomonas (3.0%), Veillonella (2.5%), Hafnia (2.0%), Prevotella (1.7%), Rhodococcus (1.6%), and Granulicatella (1.4%). Overall, use of Norgen's Milk DNA Preservation and Isolation Kit best maintained the consistency of the bacterial community structure. Total DNA, diversity, and evenness metrics were also highest in samples preserved with this method. CONCLUSIONS When collecting human milk for bacterial community analysis in field conditions where cold storage is not available, our results suggest that Norgen's Milk DNA Preservation and Isolation Kit may be a useful method, at least for a period of 2weeks.

Abstract
OBJECTIVES Human milk banks need to extend the suitability of milk for breastfeeding, and for this technological advances are required. Our aim was to establish the capacity of freeze-drying to conserve milk properties without further oxidative deterioration. METHODS One hundred sixteen healthy women participated from the city of Cordoba (Argentina). Proteins, glucose, triglycerides, polyphenols, and markers (nitrites, superoxide anion, hydroperoxides, lipoperoxides, and γ-glutamyl transpeptidase) were measured in their fresh milk. Samples were then separated for three treatments as follows: freezing and conservation for 6 months at -80°C (F: positive control); freeze-drying for 24 hours at ≤-70°C and ≤1.33 Pa and conservation for 6 months at 4°C (FD: treatment of interest); and freeze-drying for 24 hours at ≤-70°C and ≤1.33 Pa and conservation for 6 months at -80°C (FD+F). Next, analyses were repeated and compared by ANOVA and Tukey tests. RESULTS Fresh milk showed these values per L as follows: proteins: 12.62 ± 2.51 g, glucose: 4.44 ± 0.25 g, triglycerides: 34.26 ± 0.59 g, polyphenols: 53.27 ± 8.67 mg, nitrites: 62.40 ± 19.09 mg, superoxide: 3,721.02 ± 198.80 OD, hydroperoxides: 7,343.76 ± 294.53 OD, lipoperoxides: 7,349.72 ± 398.72 OD, and γ-glutamyl transpeptidase: 4.66 ± 0.55 IU. Glucose was decreased after F treatment (p < 0.05), all variables were conserved by FD and were not improved by the FD + F combination. CONCLUSIONS Freeze-drying achieved suitable conservation and may improve bank functioning, by protecting nutritional properties, polyphenol-related functionality, and oxidative integrity of human milk through a 1-day treatment with easy maintenance.

Abstract
Sialic acid (Sia) contents and bioaccessibility (BA) in human milk (HM) and infant formulas (IFs) were determined, and Sia intakes by infants between 0 and 6 months of age were evaluated. Total Sia contents in HM decreased during lactation from 136.14 to 24.47 mg/100 mL. The total Sia contents in IFs (13.15-25.78 mg/100 mL) were lower than in HM and were not related to the addition of ingredients acting as sources of Sia in their formulation. The Sia intakes derived from IF consumption were lower than in HM, and only one IF reached the intakes provided by HM from the age of 2 months. Despite the lower total Sia content in IFs, the BA of Sia in IFs (88.08-92.96%) was significantly greater than in mature HM (72.51%) and similar to that found in colostrum (96.43%). However, the Sia contents in the available soluble fraction of IFs did not reach those provided by HM.
