摘 要:采用直接干燥法测定海上吊笼养殖和循环水养殖的马氏珠母贝软体部鲜肉含水量,用湿法消解软体部干肉后,分别用电感耦合等离子体原子发射光谱法(ICP-AES)测定其钙(Ca)、镁(Mg)、锌(Zn)、铁(Fe)、铬(Cr)元素含量和用电感耦合等离子体质谱法(ICP-MS)测定其硒(Se)、铜(Cu)、锰(Mn)、镍(Ni)、钒(V)、钼(Mo)、镉(Cd)、钴(Co)元素含量。结果表明:相同养殖时间不同养殖模式下,马氏珠母贝鲜贝肉水分含量及13种元素含量除了元素钴(Co)和硒(Se)外,其他都存在显著差异(P<0.05);循环水养殖模式下,元素Mg,Ca,Zn,Fe,Cr,Cu的含量高于海上吊笼养殖模式,而元素Mn,Cd,Mo,V,Ni的含量则低于海上吊笼养殖模式;元素Co和Se在2种养殖模式下无明显差异。Pinctada martensii,cultured in two different culture methods: sea cage aquaculture and re-circulating aquaculture were collected to determine the water content in their soft tissue by using direct-drying method,and their mineral elements( Ca,Mg,Zn,Fe,Cr,Se,Cu,Mn,Ni,V,Mo,Cd and Co) by using ICP-AES and ICP-MS after processed by wet digestion method. The results show the 13 mineral elements in the soft tissue of P. martensii cultured for the same period of time but under different culture methods were significantly different( P〈0. 05),except Co and Se. P. martensii had a higher content of Mg,Ca,Zn,Fe,Cr,Cu in the soft tissue under re-circulating aquaculture than under the sea cage aquaculture,but a lower content of Mn,Cd,Mo,V and Ni. No obvious significance was observed in mineral elements Co and Se under the two culture methods.
