In the development of a geographical traceability model, it is necessary to understand if the value of the monitored indicators in a food is correlated to its origin or if it is also influenced by 'external factors' such as those coming from its production. In this study, a deeper investigation of the trend of direct geographical traceability indicators along the winemaking process of two traditional oenological products was carried out. Different processes were monitored, sampling each step of their production (grape juice, intermediate products and wine). The results related to the determinations of δ(18)O, (D/H)I, (D/H)II, δ(13)C, δ(15)N and (87)Sr/(86)Sr have been reported. Furthermore, correspondence with the isotopic values coming from the respective soil and vine-branch samples have been investigated as well, showing the optimal traceability power of the monitored geographical tracers.
在地理溯源模型的开发中，有必要了解监测食品中指标的值是否与其起源相关，或者是否还受到“外部因素”的影响，如来自生产过程的因素。在这项研究中，对两种传统酿造产品的酿酒过程中直接地理溯源指标的趋势进行了更深入的调查。监测了不同的工艺，对其生产过程中的每一步进行采样（葡萄汁、中间产品和葡萄酒）。报告了与 δ(18)O、(D/H)I、(D/H)II、δ(13)C、δ(15)N 和 (87)Sr/(86)Sr 的测定有关的结果。此外，还研究了与各自土壤和葡萄藤样本的同位素值的对应关系，显示了所监测地理示踪剂的最佳溯源能力。
