Özet

Salmonella contamination of fish after harvest is a significant food safety risk. To control this risk, it was aimed to reduce Salmonella Enteritidis in sea bass by helium and air plasma. Considering that preserving the fresh properties of sea bass is important for industrial applicability, determining the sensory effects of plasma treatments was also aimed. Since air plasma would provide a cheaper and easier alternative to helium plasma, their effects were compared. Additionally, the in vitro effects of these treatments on Salmonella Enteritidis were also investigated. Air and helium plasma completely inhibited the initial load of S. Enteritidis (2.79 Log CFU) inoculated on agar surface after 10 min treatment. Then, the inoculated sea bass samples were exposed to air or helium plasma for durations ranging from 1 to 15 min. Air and helium plasma treatments for 10 min provided 0.90 log cfu g(-1) and 1.13 Log CFU/g reductions, respectively, but longer treatments did not lead to further significant reductions. Sensory scores were all above 7 (good) when samples were treated with air or helium plasma for 1-10 min, but longer treatments resulted in lower scores. The reduction of S. Enteritidis and changes in sensory characteristics were interpreted together and it was concluded that 10 min of air or helium plasma provided maximum reduction without causing any significant sensory changes. Overall, the current study showed that atmospheric pressure air and helium plasmas can be useful for ensuring post-harvest safety in the fish trade.
