Advanced chitosan-based biopolymer systems for probiotic microencapsulation: stability enhancement and targeted...

Probiotic microencapsulation is an advanced technique designed to protect live probiotic microorganisms by enclosing them within a protective matrix, typically composed of biocompatible biopolymers.

This review provides a comprehensive analysis of recent advancements in bio-polymer coatings for probiotic microencapsulation, with a focus on chitosan and its synergistic combinations with other materials.

This methods highlights the necessity for continued innovation in bio-polymer coatings, emphasizing the development of bio-responsive materials, AI-driven formulation strategies, and next-generation encapsulation technologies to meet the evolving demands of functional foods and precision therapeutics.

Probiotic microencapsulation plays a critical role in protecting probiotics from environmental stresses, improving stability, and ensuring targeted delivery. Innovations in chitosan-based encapsulation, including its combination with bio-polymers such as alginate, gelatin, and pectin, have enhanced encapsulation efficiency, controlled release, and probiotic viability. Cutting-edge techniques such as nanotechnology, stimuli-responsive coatings, and hybrid bio-polymers are explored for their potential to optimize probiotic performance in food and pharmaceutical applications.

Despite these advancements, obstacles remain in ensuring consistent release profiles, mitigating the inhibitory effects of chitosan on certain probiotic strains, and optimizing large-scale production while maintaining cost-effectiveness. The need for personalized probiotic therapies has driven research into adaptive encapsulation systems tailored to individual gut microbiota compositions.
