(13)C NMR spectroscopy was employed for evaluating glucose and fructose isoforms content in Traditional Balsamic Vinegar of Modena. With the use of reference spectra recorded in water for samples obtained with respect to set rules, a shift determination method for fructose carbon isoforms was introduced to determine the frauds present in unknown Traditional Balsamic Vinegar of Modena samples. No sample preparation yields this approach highly reliable and time saving. Following this approach, for the first time, an objective analytical technique can be used alternatively to the actual procedures for Traditional Balsamic Vinegar certification.
采用(13)C核磁共振光谱法评估摩德纳传统香醋中葡萄糖和果糖异构体的含量。通过使用按照既定规则获取的样品在水中记录的参考光谱,引入了一种果糖碳异构体的位移测定方法,以确定未知的摩德纳传统香醋样品中存在的掺假情况。无需样品制备,这种方法就具有高度可靠性且节省时间。按照这种方法,首次可以使用一种客观的分析技术来替代传统香醋认证的实际程序。
