This study attempts to delineate the nutritional value and potential problem of toxic metal contamination in Sardinella maderensis (Lowe,1838) originating from Mauritanian fishery destined for regional common human consumption. Samples caught in Mauritania were delivered to Turkey by ship in 22 days in cold storage. Amino acids, fatty acids and toxic metal analyses of the samples were carried out by using a HPLC (High Performance Liquid Chromatograph), GC (Gas Chromatography) and a ICP‐MS (Inductively Coupled Plasma‐Mass Spectrometry), respectively. Overall, the range of total Saturated Fatty Acids (SFAs), Monounsaturated Fatty Acids (MUFAs) and Polyunsaturated Fatty Acids (PUFAs) were found to be 34.35%, 28.13% and 34.50%, respectively. In terms of Eicosapentaenoic acid (EPA)+Docosahexaenoic acid (DHA) levels were found to be in total 24.34%. Amino acids content such as glutamic acid, histidine, leucine and lysine were 1735.5, 1,409, 1,580 and 1,710.5 mg/100 g tissue, respectively. Toxic metal levels of Hg, Cd, As, Cr, Mn, Co were determined to reach values between 0.03–4.19 mg/kg. Athough the study is limited, it seems that results on the composition of fatty acids and amino acid, indicate the high nutritional value, well suited for human consumption in particular in terms of omega 3 and essential amino acids.

从毛里塔尼亚渔业获得的玛氏沙丁鱼的营养成分和重金属含量(Lowe,1838年)

这项研究试图勾勒出马氏沙丁鱼的营养价值和有毒金属污染的潜在问题(Lowe,1838年)起源于毛里塔尼亚渔业,供区域人类共同消费。在毛里塔尼亚捕获的样品在冷藏中在22天内通过船运到土耳其。样品的氨基酸,脂肪酸和有毒金属分析分别通过HPLC(高效液相色谱),GC(气相色谱)和ICP-MS(电感耦合等离子体质谱)进行。总体而言,总饱和脂肪酸(SFA),单不饱和脂肪酸(MUFA)和多不饱和脂肪酸(PUFA)的范围分别为34.35%,28.13%和34.50%。就二十碳五烯酸(EPA)+二十二碳六烯酸(DHA)而言,总含量为24.34%。谷氨酸,组氨酸,亮氨酸和赖氨酸等氨基酸含量分别为1735.5、1,409、1,580和1,710.5 mg / 100 g组织,分别。测定的Hg,Cd,As,Cr,Mn,Co的有毒金属水平达到0.03–4.19 mg / kg之间。尽管研究有限,但脂肪酸和氨基酸组成的结果似乎表明营养价值很高,尤其适合人体食用,尤其是在欧米茄3和必需氨基酸方面。
