Abstract

The aim of this study was to determine aflatoxin contamination levels in maize grain produced in Samsun Province, Turkey. Forty samples of maize grain intended for animal feed in Samsun Province were analyzed. The amounts of the aflatoxins, B1, B2, G1 and G2, were quantified with a liquid chromatography (HPLC-FLD) and post-column derivatization. Recoveries ranged between 89 and 98%. The detection limits were 0.007 and 0.02 ng/g and the corresponding quantification limits were 0.022 and 0.063 ng/g. As a result, it has been shown that the accurate and sensitive HPLC-FLD method was confirmed as being appropriate for the detection of AFs in maize grain, besides, the incidence of aflatoxins in maize was very low (2.5%).

Özet

Bu çalışmada Samsun ilinde üretilen tane mısırlarda aflatoksin kontaminasyonunun araştırılması amaçlandı. Bu amaçla, Samsun ilinde hayvan yemi olarak kullanıma sunulan 40 adet tane mısır örneği analiz edildi. Aflatoksin B1, B2, G1 ve G2 düzeyleri kolon sonrası türevlendirmenin yapıldığı likit kromatografi (HPLC-FLD) sistemi ile ölçüldü. Aflatoksinlerin geri kazanım oranları %89-98, belirleme alt limitleri (LODs) 0.007- 0.02 ng/g ve hesaplama alt limitleri (LOQs) 0.022-0.063 ng/g aralığında belirlendi. Sonuç olarak, tane mısırlarda aflatoksinlerin tespitine yönelik olarak uygulanan immunoafinite kolon temizleme ve kolon sonrası brom türevlendirmesini içeren doğruluk ve hassasiyeti yüksek HPLC-FLD metodunun, aflatoksinlerin tespitinde uygun bir yöntem olarak kullanılabileceği, bunun yanında, Samsun ilinden elde edilen tane mısır örneklerinde aflatoksinle kontaminasyon oranının düşük düzeyde (%2.5) olduğu ortaya konulmuştur.
