Controllable engineered probiotic microspheres for treating ulcerative colitis: A cascade enzyme‐catalyzed strategy to restore intestinal redox homeostasis

BMEMat, EarlyView.
A dual strategy integrating genetic engineering and physical encapsulation was proposed to enhance the cell viability and antioxidant properties of probiotics. The cascade antioxidant enzymes released from probiotic microspheres restore intestinal redox homeostasis by eliminating intestinal reactive oxygen species for ulcerative colitis treatment ...

Pulsed Light Technology in Food Safety and Preservation: Principles, Applications, and Future Directions

Food Chemistry International, EarlyView.
Pulsed light technology uses short high‐intensity broad‐spectrum flashes (200–1100 nm) to inactivate microbes via DNA damage. It preserves food quality, extends shelf life, and works on liquids, meats, and produce, often combined with other hurdles for enhanced efficacy.
