贺兰山东麓子产区马瑟兰葡萄酒产地识别研究

Research on the Identification of Matheran Wine Region in the East Foot of Helan Mountain

  • 摘要: 目的:以宁夏贺兰山东麓不同子产区马瑟兰单品葡萄酒为研究对象,明确葡萄酒中碳、氧稳定同位素分馏特征,探讨碳、氧稳定同位素及矿物元素在小尺度区域葡萄酒产地识别中的可行性。方法:采集红寺堡、青铜峡、永宁、贺兰和镇北堡5个子产区马瑟兰单品葡萄酒样品45份,监测分析葡萄酒中矿物元素含量及δ13C、δ18O值,采用Fisher线性判别分析方法,构建基于稳定同位素、矿物元素的葡萄酒产地判别模型。结果:碳、氧稳定同位素在葡萄酒发酵过程中存在明显的分馏,总δ13C>乙醇δ13C>甘油δ13C,三者表现出一定的同源性;δ18O大小依次为葡萄汁δ18O>葡萄酒中δ18O>水中δ18O。As、B、K、Li、Mn、Ni、Pb、Rb、Sb、Sr、Ti、Cs元素在部分产区间存在显著差异(P<0.05),δ13C、δ18O及Ba、Ca等13种矿物元素在不同产区间不存在显著差异(P>0.05)。基于碳、氧稳定同位素构建的葡萄酒产地判别模型的正确判别率仅为40%,基于矿物元素以及碳、氧稳定同位素结合矿物元素的正确判别率均为95.6%。结论:矿物元素可有效区分不同子产区的葡萄酒样品的有效指标,但碳、氧稳定同位素不能作为小尺度区域葡萄酒产地判别的有效指标。

     

    Abstract: Objective: To explore the feasibility of using stable carbon and oxygen isotopes and mineral elements in small-scale regional wine production identification, the fractionation characteristics of stable isotopes of carbon and oxygen in wine of Matheran single wine from different sub-producing areas at the eastern foot of Helan Mountain in Ningxia were studied. Methods: Forty-five samples of Massellan single wine from 5 sub-producing areas of Hongsipu, Qingtongxia, Yongning, Helan, and Zhenbeipu were selected to analyze the mineral element contents and the values of δ13C and δ18O. The fisher linear discriminant analysis method was used to establish a wine region discriminant model based on stable isotopes and mineral elements. Result: Carbon and oxygen stable isotopes exhibited significant fractionation during wine fermentation, with a total δ13C>ethanol δ13C>glycerol δ13C, and the three showed a certain degree of homology. The order of the δ18O size was grape juice δ18O>wine δ18O>water δ18O. As、B、K、Li、Mn、Ni、Pb、Rb、Sb、Sr、Ti and Cs showed significant differences between some production areas (P<0.05). There was no significant difference in the distribution of δ13C, δ18O, Ba, Ca and other 13 mineral elements among different regions (P>0.05). The accuracy rate of origin discrimination based on stable carbon and oxygen isotopes was only 40%, while the accuracy rates based on mineral elements and carbon and oxygen stable isotopes combined with mineral elements were both 95.6%. Conclusion: Mineral elements can distinguish wine samples from different sub-producing areas effectively. Stable carbon and oxygen isotopes cannot be used to identify the producing areas of wine from different small-scale regions.
