Results showed that heating temperature and duration affect the formation and transformation of PAHs, with higher temperatures facilitating the synthesis of oxygenated PAHs, whereas longer heating times promote the accumulation of light PAHs.

The article authored by Xu and colleagues is an international collaboration with scientists from Ireland and the United States. The use of dairy powders either as an ingredient in formulations or as a finished product consumed by consumers can be limited by poor powder rehydration characteristics. Measuring the rehydration kinetics of dairy and nondairy powders such as skim milk powder and infant formula can be difficult. The authors investigated the potential of focussed beam reflectance measurement and electrical resistance tomography as online process analytical technologies (PAT) for monitoring powder rehydration. Skim milk powder and three different infant formula samples including one plant-based protein formula were studied. The authors reported good agreement between results from both PAT tools and reference laboratory measurements. Focussed beam reflectance measurement was assessed as having the potential to characterise dairy and infant formula powder rehydration as an in-line production process tool.</p>","PeriodicalId":13822,"journal":{"name":"International Journal of Dairy Technology","volume":"77 4","pages":"1025-1026"},"PeriodicalIF":2.5,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1471-0307.13151","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142555468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent research highlights the role of gastrointestinal microbial dysbiosis in the development of mastitis. This review focuses on how microbial imbalances in the rumen and intestines can compromise the integrity of the gastrointestinal barriers, allowing harmful bacteria and endotoxins, such as lipopolysaccharide, to enter the bloodstream and reach the mammary gland, triggering inflammation. This process links gastrointestinal health to mammary gland inflammation through the gut–mammary axis. Furthermore, disruptions in glucose metabolism and immune responses are implicated in the progression of mastitis. This review underscores the potential for non-antibiotic interventions aimed at restoring microbial balance to reduce mastitis incidence, providing new insights into improving dairy cow health and farm productivity.
