Effects of dielectric barrier discharge (DBD) generated plasma on microbial reduction and quality parameters of fresh mackerel (Scomber scombrus) fillets

The use of dielectric barrier discharge (DBD) to produce cold plasma showed a potential industrial application at low cost and convenience. Cold plasma was found to be effective for reducing the main problem of oily fish quality such as the spoilage bacteria. However, this technology seems to accelerate oxidative pathways; for this reason, further studies to investigate the use of antioxidants in combination with cold plasma as “hurdle technology” to minimise this negative effect are suggested.
