Özet
Bu araştırmada, farklı tipteki unlara ozon uygulamasının, hamur ve ekmek kalitesine etkisi incelenmişltir. Bu amaçla, 3 farklı tip unun (Tip 550, 650 ve 850) yarısına bir ozon jeneratörü yardımıyla ozon gazı uygulanmıştır. Diger yarısı ise, ozon uygulamaksızın kontrol grubu olarak belirlenmiştir. Un kalitesinin belirlenmesi amacıyla yaş gluten, gluten indeks ve renk (L*, a* ve b*) değerleri parametre olarak ele alınmıştır. Bu unlardan yapılan hamurların değerlendirilmesinde de, bazı farinograf ve ekstensograf özellikleri dikkate alınmış, daha sonra aynı unlardan yapılan ekmeklerin kalitatif özellikleri belirlenmiştir. Elde edilen araştırma verilerine göre; ozon uygulamaları yaş gluten miktarını, un renginin L* (parlakl›k) değerlerini arttırıcı; b* (sarılık) değerlerini ise düşürücü etkide bulunmuş olup, daha beyaz bir un elde edilmesini saglanmıştır. Ozon uygulamasının, hamur reolojik özellikleri üzerinde olumsuz bir etkisinin olmadıgı, hamur enerjisi değerlerini arttırdıgıı belirlenmiştir. Ayrıca ozonun, ekmek hacmi ve spesifik hacim değerlerini arttırıcı etkide bulundugu ortaya konulmuş, en iyi sonuçlar ise Tip 550 unlardan yapılan ekmek örneklerinde elde edilmiştir. Genel olarak ozon uygulamaları, ekmek içinin daha iyi tekstür yapısında ve beyaz olmasında olumlu etkide bulunmuştur.
This study aims to examine the effect of ozone application on quality characteristics of different types of flour samples and their dough and bread samples. For this purpose, ozone was applied to the half of the three different flour samples (Type 550, 650 and 850) by an ozone generator. The other half of the flour samples were designated as the control group with no ozone application. Wet gluten, gluten index and color values (L*, a* and b*) were undertaken as the parameters in determination of flour quality. The Farinograph and Extensograph characteristics were taken into consideration in evaluation of doughs which were made from those flours and then, the qualitative characteristics of breads made from these flours. According to the obtained data, while the wet gluten and the L* values were increased, b* values were decreased by the ozone application. Besides, it increased the whiteness of the flour. It is determined that the ozone application had no significant effect on the rheological properties of the dough but, the energy values of the dough were significantly affected. It is also found that the ozone application had a significant positive effect on the bread volumes and specific volumes, especially for the breads made from Type 550 flours. In general, the ozone application had positive effects on the textural structure and the whiteness of the crumb.
