Abstract

In this study, quality changes and shelflife ofzander fillet stored at +2d:1 °C applying sous-vide technology in different temperatures (60 °C, 70 °C and 80 °C was investigated. No important changes in biochemical composition except for protein ofall groups during the storage were found (p>0.05). The microbial load was detected in fresh samples decreased by sous-vide process, and regularly increased in all groups depending on the storage time. Total volatile basic nitrogen (TVE-N) values exceed the limit value for 60 °C group at 35tıı day (36.42 mg/ 100g) and 70 °C group at 49‘“ day (33.62 mg/ 100g), whereas 80 °C group was found in the limit value during the storage. TBA values of all groups were found in quality limit values during the storage. Sous-vide process was not significant effect on pH. Average sensory scores of sous-vide groups at 60 °C, 70 °C and 80 °C were found below the limit value at 35111 day, 49'lı day and 63'1', respectively. According to the result of chemical, microbiological and sensory analyzes, shelf life of zander fish stored at +2:I:1°C by applying the sous-vide process was determined as 28 days for 60 °C group, 35 days for 70 °C group and 56 days for 80 °Cgroup.

Özet

Bu çalışmada farklı sıcaklıkta (60 °C, 70 °C ve 80 °C sous-vide tekniği uygulanarak +2d:1 "C'de depolanan sudak balığının kalite değişimi ve raf ömrü incelenmiştir. Tüm grupların depolama süresince protein miktarı hariç besinsel kompozisyonlarında önemsiz değişimler bulunmuştur (p>0.05). Taze örnekte tespit edilen mikrobiyal yükün sous-vide işlemi sonucunda azaldığı ve depolama süresine bağlı olarak tüm gruplarda düzenli bir şekilde arttığı tespit edilmiştir. Toplam uçucu bazik azot (TVB-N) değeri 60 °C'1ik grupta 35. gün (36.42 mg/ 100g), 70 °C'1ik grupta 49. gün (33.62 mg/ 100g) sımr değerini aşarken, 80 °C'1ik grup depolama süresince smır değerleri içerisinde kalmıştır. Tüm grupların tiyobarbitürikasit (TBA) degerleri depolama süresince kalite smır değerleri içerisinde kalmıştır. Sons-vide işleminin pH üzerinde belirgin bir etkisi olmamıştır. Duyusal açıdan 60 °C, 70 °C ve 80 oC'de işlem görmüş grupların ortalama puanları sırasıyla 35. gün, 49. gün ve 63. günde smır değerlerin altında olduğu tespit edilmiştir. Elde edilen kimyasal, mikrobiyolojik ve duyusal analiz sonuçlarına göre sous-vide uygulanarak +2:I:1 oC depolanan sudak balıklarının raf ömrü 60 °C için 28 gün, 70 °C için 35 gün ve 80 °C için 56 gün olarak tespit edilmiştir.
