Abstract (2. Language): 
Bleaching clay refers to clays that in their natural or activated state have the capacity to absorb dyes and other remaining undesirable ingredients from edible oil during its purification processes. Thus, the most important function of bleaching clay is to improve the appearance, flavor, odor, and stability of the final oil product. Hexane, acetone, and methyl ethyl ketone were used as the solvents in this research, and RSM (response surface methodology) was employed for determining the optimal parameters. The variable parameters included the solvent to clay ratio (SCR) and the extraction time. Results showed methyl ethyl ketone with the final oil removal efficiency of 61.3% was superior to hexane and acetone, with efficiencies of 52.7 and 59.1%, respectively. Under the best laboratory conditions and using RSM, the highest extraction efficiency was 5.97 ml/g for the ketone solvents (acetone and methyl ethyl ketone) at the extraction time of 3 minutes and 6 seconds, and 5.92 ml/g for hexane at the extraction time of 24 minutes and 30 seconds.

Abstract (Original Language): 
Kil ağartmak terimi ile sofralık sıvı yağın arıtım aşamasında istenmeyen içerikleri ve boyaları emme kapasitesine sahip doğal veya etkinleştirilmiş durumdaki kil kastedilmektedir. Dolayısıyla, kil ağartmanın en önemli fonksiyonu yağ ürünlerinin görüntüsünü, tadını, kokusunu ve dayanıklılığını geliştirmektir. Hekzan, aseton ve methyl ethyl ketone bu çalışmada çözücü madde olarak ve RSM (Yüzeysel tepki metodolojisi) optimal parametreleri belirlemek için kullanılmıştır. Değişken parametreler kil oranı için çözücü (SCR) ve çıkarım zamanını içermektedir. Sonuçlar final yağ temizlemede methyl ethyl ketonenin %61.3 etkinlikle etkinlikleri %52.7 ve 59.1 olan hekzan ve asetona göre daha üstün olduğunu göstermektedir. En iyi labaratuar koşulları ve RSM kullanımı altında en yüksek çıkarım etkinliği ketone çözücüler (asetan ve methyl ethyl ketone) için 3 dakika 6 saniye çıkarım zamanı ile 5.97 ml/g ve hekzan için 24 dakika 30 saniye çıkarım zamanı ile 5.92 ml/g dır.
