Co-encapsulation of probiotics with functional components: design strategies, synergistic mechanisms, biomedical applications, and challenges for industrialization

imaging, and metabolic tracking, the advantages of co-encapsulation in improving probiotic survival rates, targeted release capabilities, and functional stability have been demonstrated. Furthermore, this review explores the application potential of co-encapsulation in chronic disease intervention and identifies the challenges that remain in industrial scale-up, safety standardization, and clinical translation. This review aims to provide a scientific foundation for the clinical translation and industrial application of probiotic co-encapsulation technologies.
