基于有机酸高效液相色谱的葡萄酒品质分析
发布时间：2018-11-25 21:47
【摘要】：建立了葡萄酒中7种常见有机酸的高效液相色谱检测方法,该方法条件下7种有机酸均得到了很好的分离,各有机酸的线性关系良好,检测限低,加样回收率准确度较高。使用该方法对年份葡萄酒和品种葡萄酒进行分析,发现年份和品种均对(红/白)葡萄酒中有机酸有一定的影响,其中品种的影响较大,年份的影响较小,年份对于白葡萄酒的影响远大于红葡萄酒。此外,红葡萄酒与白葡萄酒有机酸组成也明显不同,红葡萄酒中主要为酒石酸和乳酸,柠檬酸含量很低;而白葡萄酒中主要的有机酸为柠檬酸和苹果酸,其次为酒石酸。进一步分析发现,北京市售葡萄酒中有机酸品质状况整体较好,所测103款葡萄酒样品中,柠檬酸超标仅有5例,超标检出率为4.9%。使用有机酸可以有效区分葡萄酒与非葡萄酒;使用柠檬酸总量,以及柠檬酸与有机酸总量比值,可以初步检测勾兑假葡萄酒,尤其是"三精一水"勾兑的低劣等葡萄酒。进口葡萄酒与国产葡萄酒、不同产区葡萄酒、不同酒庄葡萄酒的有机酸特征均不相同。
[Abstract]:A high performance liquid chromatography (HPLC) method was established for the determination of seven common organic acids in wine. Under the conditions of this method, the seven organic acids were well separated. The linear relationship of each organic acid was good, the detection limit was low, and the accuracy of sample recovery was high. This method was used to analyze vintage wine and variety wine. It was found that both year and variety had a certain influence on organic acids in (red / white) wine, among which the influence of variety was greater than that of year. The effect of year on white wine is much greater than that on red wine. In addition, the composition of organic acids in red wine and white wine is obviously different. The main organic acids in red wine are tartaric acid and lactic acid, and the content of citric acid is very low, while the main organic acids in white wine are citric acid and malic acid, followed by tartaric acid. Further analysis showed that the quality of organic acid in the wine sold in Beijing was good as a whole. Among the 103 wine samples, only 5 cases had citric acid exceeded the standard, and the detection rate of exceeding the standard was 4.9%. Using organic acids can effectively distinguish wine from non-wine, and using total citric acid and the ratio of citric acid to organic acid, we can preliminarily detect the blending fake wine, especially the inferior wine mixed with "three essence and one water". The organic acid characteristics of imported wine are different from that of domestic wine, wine of different producing region and wine of different winery.
