Abstract

In this study, it was aimed to reveal aroma-active compounds and sensory properties of Çökelek cheese made from milk, yogurt and Tuluk yogurt. For this purpose, aroma active compounds in Çökelek samples were determined by Gas Chromatography-Olfactometry. Furthermore, sensory properties of cheese samples were determined by Spectrum® analysis. As result, 17 identified and 2 unknown aroma active compounds were determined in Çökelek samples. Butyric acid, Furaneol® and sotolon were identified at high intensities in all cheeses. It was determined that the intensity of butyric acid was higher in Çökelek made from yogurt while the intensities of Furaneol® and sotolon were found to be higher in Çökelek made from milk. “Cooked”, “Whey”, “Creamy”, “Rancid” “Fermented”, “Yeast”, “Sour”, “Salty”, “Sweet” and “Umami” were defined as characteristic sensory terms for Çökelek cheeses. It was determined that cooked, creamy and sweet were perceived in Çökelek made from yogurt while yeast aroma was found to be a higher in Çökelek made from Tuluk yogurt.

Özet

Bu çalışmada süt, yoğurt ve tuluk yoğurdundan yapılan Çökelek peynirinin aroma aktif bileşenleri ve duyusal özeliklerinin ortaya çıkarılması amaçlanmıştır. Bu amaçla, çökelek örneklerinin aroma aktif bileşenleri Gaz kromatografi Olfaktometri (GCO) yöntemi kullanılarak belirlenmiştir. Ayrıca, peynir örneklerinin duyusal özellikleri Spectrum® analizi kullanılarak tespit edilmiştir. Sonuç olarak, Çökelek örneklerinde toplam 17 adet tanımlanmış ve 2 adet de bilinmeyen aroma aktif bileşen belirlenmiştir. Bütirik asit, Furaneol® ve sotolon gibi bileşenlerin çökelek örneklerinde yüksek yoğunlukta olduğu tespit edilmiştir. Bütirik asitin aroma yoğunluğunun yoğurttan üretilen çökelekte en yüksek olduğu, Furaneol® ve sotolonun ise sütten yapılan çökelek peynirlerinde yüksek olduğu belirlenmiştir. Çökelek peynirleri için belirlenen karakteristik duyusal terimler “Pişmiş”, “Peyniraltı suyu”, “Kremamsı”, “Ransit”, “Fermente”, “Maya”, “Ekşi”, “Tuzlu”, “Tatlı” ve “Umami”dir. Yoğurttan yapılan çökelek peynirlerinde pişmiş, kremamsı ve tatlı özelliklerin daha yüksek algılandığı, Tuluk yoğurdundan yapılan çökeleklerde ise maya aromasının daha yüksek olduğu belirlenmiştir.
