<p>This study investigated the impact of magnetic particle-incorporated water-in-water (W/W) Pickering emulsions on the aggregation capacity and stability of encapsulated probiotics. The results demonstrated that the incorporation of magnetic particles did not compromise the structural integrity of the W/W Pickering emulsion under varying environmental conditions, and that the emulsion breakage was controllable under magnetic field conditions. The probiotics encapsulated in the magnetic W/W Pickering emulsion had an enhanced aggregation ability. The survival rate after spray drying of emulsion encapsulating probiotics with magnetic particles was 81.16%, a significant improvement of 12.62% compared to the control group (68.54%). This finding underscores the protective role of magnetic particles in mitigating the detrimental effects of environmental stressors on probiotic viability. Furthermore, during simulated gastrointestinal digestion, the encapsulated probiotics displayed a cell viability of 1.00 × 10⁸ CFU·g⁻¹ after gastric digestion and 9.45 × 10⁷ CFU·g⁻¹ after intestinal digestion. The excellent biocompatibility of this encapsulation system underscores its potential as an advanced material for probiotic encapsulation, providing a promising strategy for developing more robust and shelf-stable probiotic-based products.</p> Graphical Abstract <p></p>
