From Fish Waste to Stable Omega‐3 Bioactive Lipids: Encapsulation Strategies and a Conceptual Framework for Antioxidant and Antimicrobial Functional Food Fortification

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Fish waste is valorized into omega‐3‐rich bioactive lipids (EPA and DHA), followed by stabilization through advanced encapsulation technologies to prevent oxidation and improve storage stability. Encapsulation protects polyunsaturated fatty acids from oxidation, improves storage stability, enables controlled gastrointestinal release, and enhances ...

Efficacy and Efficiency of an Atmospheric Pressure Dielectric Barrier Discharge Reactor (GAPS) for Air Disinfection

Plasma Processes and Polymers, Volume 23, Issue 8, August 2026.
A Grid‐like Air Plasma Sanitiser has been tested for the inactivation of airborne pathogens. This reactor demonstrates a 4.5 and 2.5‐log reduction in aerosolized E. coli and SARS‐CoV‐2, respectively. This device shows an energy efficiency per order index, 2 orders of magnitude lower than values reported for comparable plasma‐based systems.
