Summary: Thermosonication is a viable technique to replace conventional thermal processing and has been used to kill heat-resistant Bacillus and extend the shelf life of pasteurized milk. The study found that thermosonication treatment significantly reduced the number of Bacillus subtilis and improved the quality of milk. It also had an effect on cell membrane permeability and enzyme activities. The findings suggest that this new decontamination method can be implemented in the dairy industry to enhance the quality and shelf life of pasteurized milk.

Summary: The study found that half of the surveyed outlets in Oman did not provide suitable conditions for storing pasteurized milk, with grocery stores being the main offenders. However, samples stored at 5 degrees C and 8 degrees C for 12 days showed no changes in physicochemical and microbiological properties, meeting standard specifications. This suggests that storing pasteurized milk at 5 degrees C for 9 days after production is safe.

Summary: The incidence of food allergies has increased worldwide in the past 20 years. Early introduction of allergenic foods has been shown to reduce the risk of allergies, but less is known about the introduction of cow's milk. Recent studies suggest that early introduction of cow's-milk-based formulas with intact milk proteins can reduce the risk of cow's milk allergy, while very early introduction followed by discontinuation may increase the risk.

Summary: This study investigates the impact of Saccharomyces cerevisiae on rennet-induced gelation of ultra-high temperature (UHT) milk. The results show that inoculating S. cerevisiae in UHT milk leads to an increase in ethanol content, a decrease in pH, an increase in particle size and Zeta potential, as well as an advancement and increase in the elasticity index. Additionally, the number of S. cerevisiae cells affects the structure and properties of the induced curds.

Summary: Pasteurized donor human milk (PDHM) has been shown to reduce the incidence of necrotizing enterocolitis in very low birth weight infants. However, lack of Medicaid and private insurance coverage for PDHM use in neonatal intensive care units leads to disparities based on birth state and socioeconomic status. Through collaboration between local and national American Academy of Pediatrics (AAP) chapters, a PDHM Advocacy Toolkit was created to promote Medicaid coverage. Over 5 years, advocacy efforts led by neonatologists and incentivized by AAP funds resulted in 5 additional states providing Medicaid payment for PDHM, increasing the coverage to over 55% of nationally born very low birth weight infants. This case study provides a template for other pediatric specialists to advocate for niche-focused issues at the state level.

Summary: Although we have gained extensive understanding of the diversity of microbial life on earth through culture-independent metagenomic DNA sequence analyses, the isolation and cultivation of microbes is still crucial for direct study and confirmation of their functions and roles. However, the majority of environmental microbes remain uncultured, making it a priority to culture these rare or poorly characterized groups in order to further understand microbiome functions. Additionally, cultivated isolates may have various applications such as new probiotics, biocontrol agents, and industrial processes. The increasing availability of metagenomic and meta-transcriptomic sequence information allows for more opportunities to guide the isolation and cultivation of microbes of interest.

Summary: Colonization and development of the gut microbiome are essential for the growth and health of calves. This review summarized the colonization, beneficial nutrition, immune function, gut barrier function, and evolution of core microbiota in the gut of calves of different ages. Homeostasis of the gut microbiome is beneficial for the nutritional and immune system development of calves. Disruption of the gut microbiome leads to digestive diseases in calves, such as diarrhea and intestinal inflammation. Colonization of microbiota in the gut of calves is influenced by various factors, including probiotics, diet, age, and genotype. The interaction between gut microbiota and the immune system of calves is crucial for colonization. The abundance and diversity of commensal microbiota play a critical role in the health of calves.

Summary: The aim of this research was to establish a method for quantifying 10 short-chain fatty acids (FSCFAs) in raw cow milk. Acidified raw cow milk samples were processed using gas chromatography-mass spectrometry after pretreatment with hydrochloric acid ethanol (0.5%) solution. Except for iso C5:0 and anteiso C5:0 co-elution, the remaining eight FSCFAs were effectively separated by chromatography. The methodological validation showed satisfactory linear relationships, low limits of quantification, good recoveries, and precision. Our study provides a valuable method for future quality and safety control of raw milk and nutritional studies.
