Fish and seafood are highly perishable commodities, necessitating innovative packaging solutions to mitigate microbial spoilage extend shelf life. This study developed a bioactive nanocomposite biosensor incorporating phycocyanin (PC) pigment extracted from Neowestiellopsis persica functionalized under 30 60 Millitesla (mT) magnetic fields (MF) coated with nanochitosan (NCT)- Sodium Alginate (SA). Reaults showed that MF exposure enhanced PC purity concentration by 1.04- 1.12-fold, respectively (p < 0.05), compared non-MF controls. Agar disk diffusion assays revealed 1.12-fold (30 mT) 1.15-fold (60 increase in antibacterial activity against Staphylococcus aureus. Films containing 2% (T4) extended life 8 days refrigeration, reducing thiobarbituric acid (TBA) total volatile nitrogen (TVN) levels 18.85 ± 0.39 mg MDA/kg mg/100 g, respectively, over 15 days. Furthermore, T4 significantly suppressed proliferation relative lower-concentration treatments controls 0.05). These results demonstrate MF-enhanced, nanocomposites provide sustainable, biodegradable solution for preservation, effectively delaying advancing technologies.
