Özet
Bu çalışmada İskenderun Körfezinde avlanan, ekonomik değeri yüksek balık türleri olan mercan (Nemipterus randalli) ve sardalya (Sardinella aurita)? dan elde edilen surimilerin ham protein, ham yağ, ham kül, nem ve ağır metal (Cu, Mn, Cr, Fe, Ni, Zn, Pb, Cd ve As) içerikleri tespit edilmiştir. İskenderun balık pazarından temin edilen balıklar bir işleme tekniği olan geleneksel surimi yöntemiyle işlenmiştir. Elde edilen surimilerin ağır metal içerikleri ICP-OES kullanılarak ölçülmüştür. Araştırma sonucunda her iki tür için ham balık ve suriminin protein değerleri arasındaki farkın önemli olmadığı; ham yağ ve ham kül değerlerinin surimi yapılmış balıkta önemli derecede düştüğü tespit edilmiştir (p<0.05). Ham balıkta % 76.0 olan nem içeriğinin surimide % 81.5?e çıktığı gözlenmiştir (p<0.05). Mercan ve mercan surimide Cd, Cr, Mn, Ni ve Pb değerleri arasındaki farkın istatistiksel olarak önemli olmadığı; Cu, Fe ve Zn değerlerinin surimi yapılmış balıkta önemli derecede arttığı tespit edilmiştir (p<0.05). Ham balıkta 0.94 mg/kg olan As içeriğinin surimide 0.72 mg/kg?a düştüğü gözlenmiştir (p<0.05). Sardalya ve surimisinin Cd, Cr, Cu, Mn, Ni ve Pb değerleri arasındaki farkın istatistiksel olarak önemli olmadığı; Zn değerlerinin surimi yapılmış balıkta önemli derecede arttığı tespit edilmiştir (p<0.05). Ham balıkta 1.14 mg/kg olan As içeriğinin surimide 0.72 mg/kg; 10.45 mg/kg olan Fe içeriğinin 7.80 mg/kga düştüğü gözlenmiştir (p<0.05). Her iki türün surimi örneklerinde As değerlerinin azaldığı dikkati çekmektedir.
In this study, the crude protein, crude fat, ash, moisture and heavy metal (Cu, Mn, Cr, Fe, Ni, Zn, Pb, Cd, As) contents of surimi from Nemipterus randalli, Sardinella aurita that high economic value in İskenderun Bay have been determined. Fish obtained from the fish bazaar in İskenderun was processed by the traditional surimi method that a common processing technique. Heavy metal content measurement were done by first wet burning and then by using ICP-OES. As result of research, there was not significant the differences between protein values of fish and surimi; It was determined that crude fat and crude ash values decreased significantly in surimi (p<0.05). It was observed that moisture content increased from %75.95 to % 81.46 in fish (p<0.05). There was not any significant differences between Cd, Cr, Mn, Ni ve Pb values of Nemipterus randalli and surimi; It was determined that Cu, Fe, Mn values increased significantly in surimi (p<0.05). As value was found 0.94 mg/kg in fish; however this value decreased in surimi to 072 mg/kg (p<0.05). There was not any significant difference between Cd, Cr, Cu, Mn, Ni and Pb values of Sardinella aurita and surimi; It was determined that Zn value increased significantly in surimi (p<0.05). As and Fe values were found 1.14 mg/kg and 10.45 in fish; however these values decreased in surimi to 072 mg/kg and 7.80 mg/kg (p<0.05). It is noteworthy that the As the values of surimi samples of both species decreased. Key words: Nemipterus randalli, Sardinella aurita, proximate composition, surimi, heavy metal
