慕萨莱思葡萄酒中13种常见金属元素及硒含量分析

Analysis of thirteen kinds of common metallic elements and selenium in the Msalais wine

采用火焰原子吸收光谱法、石墨炉原子吸收光谱法和原子荧光光度法测定阿瓦提慕萨莱思成品酒、红提葡萄原汁、实验室自酿慕萨莱思及酒泥中镁(Mg)、铁(Fe)、铜(Cu)、锰(Mn)、锌(Zn)、钙(Ca)、铅(Pb)、镉(Cd)、镍(Ni)、铬(Cr)、钴(Co)、钾(K)、钠(Na)和硒(Se)14种元素含量。结果表明,慕萨莱思葡萄酒中富含Na、K、Fe、Mg、Ca和Se,其Pb、Cd和Cr等重金属元素均符合国家标准限量,但阿瓦提慕萨莱思葡萄酒中Fe含量显著高于实验室自酿慕萨莱思(P<0.01),为12.13~13.35 mg/L,已超出我国葡萄酒国家标准(≤8 mg/L),但未超出新疆地方标准的限量(≤15 mg/L)。此外,酒泥中富含绝大多数金属元素和Se。由此,实验室自酿慕萨莱思的酿制工艺可有效降低Fe含量。

14 kinds of elements （Mg, Fe, Cu, Mn, Zn, Ca, Pb, Cd, Ni, Cr, Co, K, Na, Se） in Awati Musalais wine products, red grape juice, Msalais wine brewed in laboratory and wine lees were detected by flame atomic absorption spectrometry, graphite furnace atomic absorption spectrometry and atomic fluorescence spectrophotometry. The results showed that the Msalais wine was rich in Na, K, Fe, Mg, Ca and Se. The heavy metal elements （Pb, Cd and Cr, etc.） were all in line with the national standard. But the Fe content （12.13-13.35 mg/L） in Awati Msalais wine products was significantly higher than that of Msalais wine brewed in laboratory （P〈0.01）, and was above the national standard of wine in China （≤8 mg/L）, but was in line with the Xinjiang local standard （≤15 mg/L）. In addition, the wine lees were rich in most metal elements and Se. The brewing technology of Msalais wine brewed in laboratory could reduce Fe content effectively.
