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.

Assessment trial of the effect of enteral insulin on the preterm infant intestinal microbiota. Pediatr Res 2024; 95:1117-1123. [PMID: 38086952 DOI: 10.1038/s41390-023-02917-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 10/05/2023] [Accepted: 10/25/2023] [Indexed: 03/09/2024]
Abstract
BACKGROUND Insulin might be associated with changes in infant gastrointestinal microbiota. The objective of this randomized controlled trial was to assess the efficacy of two doses of recombinant human(rh) enteral insulin administration compared to placebo in intestinal microbiota. METHODS 19 preterm patients were recruited at the NICU of La Paz University Hospital (Madrid, Spain). Subjects received 2000 µIU of rh enteral insulin/ml(n = 8), 400 µIU of rh enteral insulin/ml(n = 6) or placebo(n = 5) for 28 days administered once per day. Extracted DNA from fecal samples collected at the beginning and end of treatment were analyzed. The 16S rRNA V4 region was amplified and sequenced in a Miseq(Illumina®) sequencer using 2 × 250 bp paired end. Resulting reads were filtered and analyzed using Qiime2 software. Metabolic activity was assessed by GC. RESULTS Gestational age and birth weight did not differ between groups. At the phylum level, both insulin treated groups increased the relative abundance of Bacillota, while Pseudomonadota decreased. No change was observed in infants receiving placebo. At the genus level, insulin at both doses showed enriching effects on Clostridium. We found a significant increase in concentrations of fecal propionate in both rh insulin treated groups. CONCLUSION Rh insulin may modify neonatal intestinal microbiota and SCFAs in preterm infants. IMPACT STATEMENT Decrease of Pseudomonadota (former Proteobacteria phylum) and increase of Bacillota (former Firmicutes phylum) obtained in this study are the changes observed previously in low-risk infants for NEC. The administration of recombinant enteral insulin may modify the microbiota of preterm new-borns and SCFAs. Modulation of the microbiota may be a mechanism whereby insulin contributes to neonatal intestinal maturation and/or protection.

Abstract
The composition of human milk is influenced by storage and processing practices. The effects of thawing and warming practices on human milk composition remain poorly studied despite their prevalence in home, research, and donor milk bank settings. This review comprehensively examines the impact of different thawing and warming methods on nutritional and bioactive human milk components. While some components such as carbohydrates and minerals remain stable under most typical thawing and warming conditions, others, such as fat, immune proteins, bacterial and human cells, and peptide amine hormones, are sensitive to warming. This review has identified that the data on the effects of milk thawing and warming is limited and often contradictory. Given that numerous important components of milk are diminished during cold storage, it is important that thawing and warming practices do not lead to further loss of or alterations to beneficial milk components. Further work in this field will facilitate greater standardization of thawing methods among researchers and underpin recommendations for thawing and warming of expressed milk for parents.

Abstract
Although Holder pasteurization is the recommended method for processing breast milk, it does affect some of its nutritional and biological properties and is ineffective at inactivating spores. The aim of this study was to find and validate an alternative methodology for processing breast milk to increase its availability for newborn babies and reduce the financial loss associated with discarding milk that has become microbiologically positive. We prepared two series of breast milk samples inoculated with the Bacillus cereus (B. cereus) strain to verify the effectiveness of two high-pressure treatments: (1) 350 MPa/5 min/38 °C in four cycles and (2) cumulative pressure of 350 MPa/20 min/38 °C. We found that the use of pressure in cycles was statistically more effective than cumulative pressure. It reduced the number of spores by three to four orders of magnitude. We verified that the method was reproducible. The routine use of this method could lead to an increased availability of milk for newborn babies, and at the same time, reduce the amount of wasted milk. In addition, high-pressure treatment preserves the nutritional quality of milk.

Abstract
Human milk and commercial dairy products play a vital role in humans, as they can provide almost all essential nutrients and immune-active components for the development of children. However, how to retain more native immune-active components of milk during processing remains a big question for the dairy industry. Nonthermal technologies for milk processing are gaining increasing interest in both academic and industrial fields, as it is known that thermal processing may negatively affect the quality of milk products. Thermosensitive components, such as lactoferrin, immunoglobulins (Igs), growth factors, and hormones, are highly important for the healthy development of newborns. In addition to product quality, thermal processing also causes environmental problems, such as high energy consumption and greenhouse gas (GHG) emissions. This review summarizes the recent advances of UV-C, ultrasonication (US), high-pressure processing (HPP), and other emerging technologies for milk processing from the perspective of immune-active components retention and microbial safety, focusing on human, bovine, goat, camel, sheep, and donkey milk. Also, the detailed application, including the instrumental design, technical parameters, and obtained results, are discussed. Finally, future prospects and current limitations of nonthermal techniques as applied in milk processing are discussed. This review thereby describes the current state-of-the-art in nonthermal milk processing techniques and will inspire the development of such techniques for in-practice applications in milk processing.
