The objective of this study was to investigate the effect of Cherry laurel marmalade (0%, 5%, 10%, 15%, and 20%) on the physico-chemical and sensorial characteristics of yogurts during the storage time. Increasing marmalade concentrations into the yogurts affected titratable acidity, a* values and overall acceptability positively, and viscosity, syneresis and L* values negatively. During storage time pH, viscosity, syneresis, b* values, flavour and overall acceptability scores (P<0.05) decreased significantly compared to control, while titratable acidity and a* values (P<0.05) increased significantly. When compared to L* values at the end of storage time with the first day L* values, at the marmalade added samples were observed an increasing but, at the control samples a decreasing were observed. 15% cherry laurel marmalade would be recommended in the production of fruit yogurts.

Depolama Süresince Pıhtısı Kırılmış Yoğurtların Fizikokimyasal ve Duyusal Özellikleri Üzerine Karayemiş Marmeladının Etkisi (İngilizce)

Öz

Bu çalışmanın amacı, depolama süresince yoğurtların fizikokimyasal ve duyusal özellikleri üzerine karayemiş marmeladının (%0, %5, %10, %15 ve %20) etkisini incelemektir. Yoğurtlara ilave edilen marmelat konsantrasyonunun artırılması titrasyon asitliğini, a* değerini ve genel kabul edilebilirliliği pozitif olarak, viskozite, su salma, L* değerlerini ise negatif olarak etkilemiştir.  Depolama süresince pH, viskozite, su salma, L* ve b* değerleri tat ve genel kabul edilebilirlilik puanları kontrolle karşılaştırıldığında önemli düzeyde azalırken (P<0.05) titrasyon asitliği ve a* değeri önemli düzeyde artmıştır (P<0.05). Depolamanın 1. günündeki L* değerleri depolama sonundaki L* değerleriyle karşılaştırıldığında, marmelat ilaveli örneklerde bir azalma gözlemlenmiş fakat konrol örneklerinde bir artış belirlenmiştir.  Meyveli yoğurtların üretiminde %15 karayemiş marmeladı tavsiye edilebilmektedir.
