Review highlights advances in sustainable coatings for probiotic delivery, indicating their potential in food packaging.
The urgent need to replace fossil fuel-based packaging has accelerated the development of sustainable and functional alternatives. Concurrently, maintaining probiotic viability across processing, storage, and gastrointestinal transit remains a critical challenge. Edible and bioactive coatings derived from renewable resources have emerged as multifunctional systems addressing both sustainability and delivery efficiency. This review highlights recent advances in coatings developed from food by-products, positioning them within circular economy strategies. Evidence demonstrates that engineered matrices significantly enhance probiotic viability through physical protection, antioxidant and antimicrobial effects, and optimized microenvironments. Their application in real food systems further improves shelf life and microbial control, underscoring their potential as next-generation functional packaging platforms.
