Shelf-life extension of refrigerated rainbow trout fillets using chitosan/gelatin bilayer film enriched with ZnO nanoparticles and tea polyphenols

Abstract This study aimed to evaluate the effect of a chitosan–gelatin film incorporated with zinc oxide nanoparticles (ZnO NPs) and tea polyphenols (TPs) on the bacterial count, physicochemical properties, and sensory attributes of rainbow trout during refrigerated storage. To a...

Purple sulfur bacteria convert aquaculture waste into antioxidant-rich single-cell protein through biofloc technology

Global aquaculture confronts twin sustainability imperatives: dwindling fishmeal supplies due to overfishing and the annual generation of over 20 million tonnes of processing by-products. Addressing these interconnected challenges, we developed an integrated bio-valorization stra...
