In this paper, 22 samples consisting of Balsamic vinegar of Modena and two Traditional Balsamic vinegar of Modena samples have been analyzed by means of (1)H NMR spectroscopy. Some selected resonances have been used for quantification and for T1 (spin-lattice relaxation time) measurements. Statistical protocols applied to NMR data for quantification of selected resonances revealed the possibility to differentiate the samples according to their ageing process. Additionally, T1 measurements revealed a strong correlation with the ageing process and these new data were added for improving the statistical model, which was used to predict T1 relaxation time of selected compounds for Balsamic vinegar samples. Our results indicate that the use of NMR data and statistical methods is a valid approach that can be successfully used for ageing characterization of Balsamic vinegar of Modena samples.
在本文中，采用¹H NMR光谱法对22个由摩德纳香醋和两个摩德纳传统香醋样品组成的样本进行了分析。一些选定的共振峰被用于定量分析和T1（自旋晶格弛豫时间）测量。应用于NMR数据以对选定共振峰进行定量分析的统计方法表明，有可能根据样品的陈酿过程对其进行区分。此外，T1测量结果显示与陈酿过程有很强的相关性，并且添加了这些新数据以改进统计模型，该模型用于预测摩德纳香醋样品中选定化合物的T1弛豫时间。我们的结果表明，使用NMR数据和统计方法是一种有效的方法，可成功用于摩德纳香醋样品的陈酿特性表征。
