Extending shelf life of Atlantic salmon: MAP and nisin

Atlantic salmon is often used in laboratory experiments to represent marine fishes. Researchers at Clemson University US determined the preservation effectiveness of combining modified atmosphere package (MAP) and nisin on fresh Atlantic salmon using various methods. The presence of CO₂ effectively inhibited the growth of bacteria while nisin only inhibited the growth of aerobic microorganisms. Tests indicated that CO₂ can efficiently delay the spoilage of Atlantic salmon while nisin has less of an impact on the shelf-life. The experiments support the combination of MAP and nisin as an effective method to limit the spoilage of Atlantic salmon compared to traditional preservation methods.
