Abstract

Bu çalışma da vakum altında paketlenip pişirilmiş (Sous
vide) sonrasında da buzdolabı sıcaklığında (3 °C) saklanan kuzu ciğerinin
kalitesindeki değişimler incelenmiştir. Numuneler vakum altında poliamid
polietilen torbalar içine paketlenerek 40 dakika boyunca 80 °C'lik bir su
banyosunda pişirilmiş ve 0, 2 ,4, 6, 8 ve 10 hafta süreyle 3 °C'de
saklanmıştır. Her hafta ciğer örnekleri üzerinde duyusal, mikrobiyolojik
(toplam aerobik), kimyasal (pH), CIE lab renk (L *, a *, b * değerleri), pişme
ağırlığı kaybı ve su miktarı analizleri yapılmıştır. On hafta depolama
esnasında su miktarında, pişme ağırlığı kaybı değerlerinde, CIE Lab renk
değerlerinde ve duyusal analiz puanlarında küçük değişiklikler belirlenmiştir.
Mikrobiyolojik olarak en fazla değişim beşinci haftada (2 log kob /g)
gözlenmiştir. Ciğer örneklerinin 8 hafta sonra kabul edilemez hale geldikleri
belirlenmiştir. Enstrümantal doku ölçümlerinde (doku profil analizi, TPA),
depolama süresince numunelerde sertlik, adezif yapışkanlık kohezif yapışkanlık ve
esneklik bakımından küçük değişiklikler olduğu gözlenmiştir.

Effects of Storage on The Quality of Sous Vide Processed Lamb Liver

Abstract

This study aimed to assess the changes in quality of lamb
liver sous vide during refrigerated storage. Liver sous vide was prepared and
stored at (3 o C). Samples were packaged under vacuum into
polyamide-polyethylene pouches, cooked in a boiling water bath at 80 o C for 40
min, and stored at 3°C for 0, 2, 4, 6, 8 and 10 weeks. Sensory, microbiological
(total aerobic), chemical (pH), color (L*, a*, b* values), cooking weight loss
and water content were performed on liver samples every week. Minor changes in
water content, cooking weight loss, Hunter Lab color, and sensory score were
observed through 10 weeks. Major microbiological change was observed in 5 weeks
(2 log cfu/g). The liver sample was unacceptable after 8 weeks. Instrumental
texture measures (texture profile analysis, TPA) showed a small change in
hardness, springiness and chewiness values in sous vide processed samples
during storage time.
