Soğuk şartlarda (4±1ᵒC) Depolanan Gümüşi Havuz Balığı (Carassius gibelio)’nda Meydana Gelen Kalite Değişimleri ve Aşamalı Çoklu Regresyon Yöntemine Göre Raf Ömrü Tahmin Modelinin Geliştirilmesi

Öz

Bu
çalışmanın amacı soğuk şartlar altında depolanan Carassius gibelio’da depolama zamanı ve mikrobiyolojik, kimyasal ve
duyusal verilere dayanarak aşamalı çoklu regresyon yöntemine göre bir raf ömrü
tahmin modeli geliştirmektir. Avcılık yöntemi ile elde edilen C.gibelio bütün olarak soğuk şartlar
altında satış ortamını simüle ederek 11 gün boyunca depolanmıştır. Örnekler
depolama süresi boyunca Toplam mezofilik aerobik bakteri (TMAB), toplam
psikrofilik aerobik bakteri (TPAB), Enterobacteriaceae, Laktik Asit Bakterileri
(LAB), pH, koku, renk, tekstür ve genel beğeni açsından değerlendirilmişlerdir.
Araştırma sonuçları bütün olarak depolanan C.gibelio’nun
soğuk şartlar altında 11 gün raf ömrüne sahip olduğunu göstermiştir. Aşamalı
çoklu regresyon modeline göre sadece 2 parametre (genel beğeni ve TMAB)
kullanılarak depolama zamanının tahmininin yapılabileceği gösterilmiştir.
Bununla birlikte, F istatistiklerine göre modelin kullanılabilir olduğu araştırma
sonuçlarına göre rapor edilmiştir.
