摘要

采用火焰原子吸收光谱法和电感耦合等离子体质谱法对130份智利葡萄酒样品中17种矿物元素的浓度进行了分析。分析的元素在其他葡萄酒产区以前报告的通常浓度范围内;例如:铁，2.08±0.99 mg L -1;Zn, 0.71±0.44 mg L -1;K, 788.10±219.66 mg L -1;Na, 14.62±8.61 mg L -1。比较不同酒区样品中矿物质含量，K、Na、Mn、Mg、Zn、Cr的含量差异有统计学意义(p≤0.05)。此外，利用主成分和线性判别分析对不同产地的葡萄酒进行判别，白葡萄酒的调整率在90%以上，红葡萄酒的调整率在70%以上。

Multi-element analysis and differentiation of Chilean wines using mineral composition and multivariate statistics

The concentration of seventeen mineral elements was analyzed in 130 commercial samples of Chilean wines, using flame atomic absorption spectroscopy and inductively coupled plasma–mass spectrometry. The elements analyzed were within the usual concentration ranges previously reported in other wine regions; for instance: Fe, 2.08±0.99 mg L -1 ; Zn, 0.71±0.44 mg L -1 ; K, 788.10±219.66 mg L -1 ; Na, 14.62±8.61 mg L -1 . When the mineral content of the samples was compared among wine areas, significant differences in the concentration of K, Na, Mn, Mg, Zn, and Cr were observed ( p ≤ 0.05). Moreover, principal component and linear discriminant analyses were used to discriminate wines according to provenance, obtaining adjustments above 90 % for white wines and over 70 % for red wines.
