Abstract
Bu çalışmada, Trakya Bölgesinde üretilen ayçiçeği tohumları yağlarında bakır (Cu), demir (Fe), kadmiyum (Cd) ve kurşun (Pb) içeriklerinin belirlenmesi amaçlanmıştır. Bu amaçla, bölgedeki üç ilden (Tekirdağ, Edirne ve Kırklareli) 2007 yılı hasad döneminde toplam 90 adet ayçiçeği tohumu örneği toplanmıştır. Sokshlet n-hekzan ekstraksiyonu ile ayçiçeği tohumlarından elde edilen ham yağ örneklerinde bu elementlerin düzeyleri atomik absorpsiyon spektrofotometre (AAS) cihazı kullanılarak belirlenmiştir. Örnek hazırlama aşaması kapalı kapta mikrodalga çözümleme sistemi kullanılarak gerçekleştirilmiştir. Analiz sonuçlarına göre, Tekirdağ, Edirne ve Kırklareli illerinden yağ örneklerinde ortalama olarak sırasıyla Cd miktarları 0,11; 0,23 ve 0,12 ppm, Cu miktarları 0,12; 0,15 ve 0,11 ppm, Pb miktarları 0,23; 0,15 ve 0,24 ppm, Fe miktarları 4,83; 4,30 ve 4,27 ppm düzeylerindedir. Varyans analizlerine göre, sözkonusu illere ait örneklerin Cd ve Fe düzeylerindeki farklılıklar istatistiksel açıdan (P<0,01) önemli bulunmuştur. Elde edilen sonuçların literatür değerleri ile karşılaştırılması yapılmış olup ayçiçeği tohumları yağlarındaki metal bulaşmanın muhtemel kaynakları da ele alınmıştır.
The aim of this study was to determine the copper (Cu), iron (Fe), cadmium (Cd), and lead (Pb) contents of the oils from sunflower seeds which were grown in the Trakya region, Turkey. For this reason, the samples of sunflower seed were collected from three different provinces (Tekirdag, Edirne and Kirklareli) which are located on the Trakya region. A total of 90 sunflower seed samples from 2007 harvest seasons were collected from these different provinces. The contents of these metals in the crude oils obtained by soxhlet extraction with n-hexane from sunflower seed samples were determined by using Atomic Absorption Spectrophotometer method. Preparing sample stage was made by using microwave analyze system in close container. According to the analysis results, the average amounts in the oil samples from three different provinces (Tekirdag, Edirne and Kirklareli) were for Cd 0.11, 0.23 and 0.12 ppm; for Cu 0.12, 0.15 and 0.11 ppm; for Pb 0.23, 0.15 and 0.24 ppm; for Fe 4.83, 4.30 and 4.27 ppm, respectively. According to the analysis of variance, the differences among the provinces were statistically significant (P<0.01) with respect to Cd and Fe contents. The obtained these results were compared between the values reported in literatures. Potential sources of metal contamination of the oils from sunflower seeds were also discussed.
