Camel Milk Extracellular Vesicles as Functional Foods and Nutraceuticals: Bridging Dairy Science and Chronic Disease...

Camel milk is increasingly recognized as a premium functional food, attributed to its rich nutraceutical compounds. Recent research has concentrated on the nanoscale extracellular vesicles derived from camel milk (CM-EVs), which exhibit distinctive properties. This review examines the methodologies for isolating and characterizing CM-EVs, alongside their potential health benefits in functional foods and nutraceuticals. CM-EVs have the capacity to safeguard functional proteins, noncoding RNAs, and bioactive lipids from degradation within the gastrointestinal tract, rendering them particularly suitable for incorporation into infant formulas, adult dietary supplements, and nutraceuticals targeting chronic inflammatory and metabolic disorders. Preclinical models indicate that CM-EVs can mitigate oxidative stress, enhance intestinal barrier integrity, and modulate gut microbiota, thereby contributing to the reduction in colonic injury and inflammation. Nonetheless, the majority of these findings are derived from laboratory and animal studies, highlighting a substantial deficiency in human clinical trials. Critical research gaps remain, necessitating further investigation into the elucidation of molecular mechanisms, assessment of long-term safety, evaluation of bioavailability, and compatibility with dairy processing techniques. This review underscores the significance of CM-EVs as bioactive food components and delineates research priorities, such as standardizing isolation methods, investigating food matrix integration, and providing translational evidence for their application in nutrition and preventive medicine.
