Özet:

 


Horse mackerel (Trachurus trachurus, Linnaeus 1758) fillets were inoculated with bacteriocin-like metabolite
producer (Group A) and non-producer (Group B) strains of Pediococcus spp. (7 log CFU g-1), then samples were
vacuum packaged and stored (4°C 10 days-1). pH values did not display differences between the groups (P>0.05).
TVB-N and TMA-N values, total mesophilic and psychrophilic aerobic bacteria counts of all groups (Control, A and
B) increased rapidly (TVB-N: 30.15, 33.86, 34.65 mg 100g-1; TMA-N: 11.63, 13.07, 13.20 mg 100g-1; mesophilic
aerobic bacteria: 6.02, 6.30, 5.94 log CFU g-1; psychrophilic aerobic bacteria: 6.30, 6.24, 6.09 log CFU g-1), and
exceeded the limits at the 2nd day of storage. However, sensory scores of the inoculated samples were higher than
that of the controls during the storage. Sensory qualities of group A and B samples were acceptable until the 6th day,
while control samples spoiled at the 4th day. Therefore, it was concluded that sensory quality of treated samples were
better, but Pediococcus strains used in this study were not proper for preserving horse mackerel fillets especially at
low storage temperatures.

İstavrit (Trachurus trachurus, Linnaeus 1758) filetoları  bakteriosin-benzeri metabolit üreten ve üretmeyen Pediococcus spp. ile ikonüle edilmiş (7 log CFU/g), ve daha sonra vakum paketlenerek depolanmıştır (4oC/10 gün).  İnoküle edilmiş örneklerin duyusal puanları depolama süresince kontrollerden yüksektir (p0.05). Böylece her ne kadar uygulama yapılmış örneklerin duyusal kalitesi daha iyiyse de kullanılan Pediococcus spp.’un istavrit filetolarının özellikle düşük sıcaklıkta muhafaza edilmesi konusunda yeterli olmadığı sonucuna varılmıştır.
