GÖKKUŞAĞI ALABALIĞI (Oncorhynchus mykiss, Walbaum 1792) FİLETOLARININ MUHAFAZASI SIRASINDA KİMYASAL VE DUYUSAL KALİTESİ ÜZERİNDE DOĞAL KORUYUCU MADDELERLE ZENGİNLEŞTİRİLMİŞ KİTOSAN YENİLEBİLİR KAPLAMALARIN ETKİLERİ

Öz

Bu çalışmada, %1 yabanmersini ve %1 gojiberry ekstraktı eklenmiş kitosan kaplamalı gökkuşağı alabalığı filetolarının (8°C) depolama sırasında kimyasal ve duyusal değişimleri araştırılmıştır. Uygulamalar C1:Kontrol, C2:Kitosan, C3:Kitosan +%1 a/h yabanmersini ekstraktı, C4:Kitosan +%1 w/v gojiberry ekstraktı olmuştur. Muhafaza sırasında, numuneler her üç günde bir kimyasal (pH, TVB-N, PV ve TBA) ve duyusal (Renk, koku, görünüş, genel kabul edilebilirlik) olarak analiz edildi. Muhafaza süresi boyunca C3 ve C4 grupları C1 ve C2 gruplarına göre daha düşük pH, PV, TBA ve TVB-N değerleri gösterdi. Duyusal sonuçlar kimyasal sonuçlarla paraleldir.
