目的分析浙江省鱼、虾、蟹、贝类、螺类和软体类等33种海产品中矿物质钙(Ca)、钾(K)、钠(Na)、镁(Mg)、铁(Fe)、锌(Zn)、铜(Cu)和锰(Mn)含量。方法采用国家标准GB 5009.268—2016《食品中多元素的测定》方法测定,开展多元素之间的相关性统计分析。结果花蛤中的Ca含量最高(510.2 mg/100 g可食部);马鲛鱼中K含量最高(444.4 mg/100 g可食部);文蛤中Na含量最高(487.6 mg/100 g);扁玉螺中Mg含量最高(132.7 mg/100 g可食部);Fe和Mn含量最高的是泥螺,分别为37.35和2.6 mg/100 g可食部;Zn和Cu含量最高的均为牡蛎,分别为15.92和8.58 mg/100 g可食部。相关性分析显示,鱼类和虾蟹类中,Mn-Ca呈非常强的相关性(r=0.9438和0.8585,P<0.05),贝类中Cu-Mg、Cu-Zn、Zn-Na呈非常强的相关性(r=-0.9102、0.8501和0.8428,P<0.05)。结论浙江省不同海产品中均含有丰富的矿物质,可为居民合理膳食提供参考。

OBJECTIVE To analyze the contents of Ca, K, Na, Mg, Fe, Zn, Cu and Mn in 33 kinds of marine products, such as fish, shrimp, crab, shellfish and mollusk. METHODS The national standard GB 5009.268-2016 Determination of multi elements in foods was used for determination. The correlation between multi elements was statistically analyzed. RESULTS The highest level of Ca was found in clam(510.2 mg/100 g edible), K in mackerel(444.4 mg/100 g edible), Na in clam(487.6 mg/100 g edible), Mg in conch(132.7 mg/100 g edible). The highest level of Fe and Mn was in conch(37.35 and 2.6 mg/100 g edible). The highest level of Zn and Cu was in oyster(15.92 and 8.58 mg/100 g edible). The correlation analysis showed that Mn-Ca was highly correlated in fish and shrimp(r=0.9438 and 0.8585, P < 0.05), while Cu-Mg, Cu-Zn, Zn-Na were highly correlated in shellfish(r=-0.9102, 0.8501 and 0.8428, P < 0.05). CONCLUSION There are rich mineral elements in different seafood, which can provide reference for the reasonable diet of residents.
