Mucoadhesive microcapsules for the delivery of probiotic-derived extracellular vesicles
Abstract Probiotic efficacy depends not only on gastrointestinal survival but on mucosal adhesion and the capacity to deliver bioactive molecules at the intestinal surface. This study optimized a whey protein isolate (WPI)–chitosan (CS) matrix for spray drying microencapsulation of Lacticaseibacillus casei BL23 using c...
