BACKGROUND: Microencapsulation improves the storage, handling, and administration of probiotics by protecting them from environmental factors and adverse conditions in the gastrointestinal tract. This process facilitates their controlled delivery in the body, which can simplify their use in therapies without compromising their therapeutic efficacy. OBJECTIVES: This study investigates the microencapsulation of METHODS/RESULTS: Synbiotic microencapsulation was carried out using spray drying with maltodextrin, gum Arabic, and inulin, achieving an encapsulation efficiency of 90.76%. The resulting microcapsules exhibited remarkable resistance to simulated gastrointestinal conditions in vitro, maintaining a survival rate of 90%. The drying process did not compromise the probiotic characteristics of the bacteria, as they demonstrated enhanced auto-aggregation, hydrophobicity, and phenol tolerance. The therapeutic potential of the microencapsulated synbiotic was evaluated in a murine model of dextran sodium sulfate-induced ulcerative colitis. The results revealed that mice treated with microencapsulated CONCLUSIONS: These findings suggest that microencapsulated
