中文摘要:

      产地溯源是保护产品原产地信息及以假乱真等农产品安全问题的有效保障, 而稳定同位素溯源技术具有高精准的示踪及溯源能力, 是农产品产地溯源的有效手段, 该技术在国内外已有显著成果。基于这些研究成果, 本综述归纳了近5年(2018—2022年)农产品中轻、重元素稳定同位素在产地溯源和真伪鉴别方面的应用进展, 阐述了稳定同位素与其他技术相结合溯源的研究, 并依据判别结果得出结论: 增加采样数量、扩大采样范围、筛选有效溯源指标、选取适当的化学计量学方法, 同时利用多种分析技术融合鉴别, 从而提高溯源正确率, 完善农产品溯源体系, 为稳定同位素今后的研究提供参考。

英文摘要:

      Origin traceability is an effective guarantee to protect the safety of agricultural products, such as the information of the origin of products and pass a fake off as a real one. Stable isotope traceability technology obtains high-precision tracing and traceability capabilities, which is an effective means to trace the origin of agricultural products. This technology has achieved remarkable results at home and abroad. Based on these research results, this review summarized the application progress of stable isotopes of light and heavy elements in agricultural products in the origin traceability and identification of authenticity of the past 5 years (2018—2022), and expounded the research of stable isotope combination with other technologies. The article has drawn conclusions based on the judgment results: By increasing the number of samples, expanding the sampling range, screening effective traceability indicators, selecting appropriate chemometric methods, and using multiple analysis techniques for fusion identification, the correct rate of traceability can be improved. This manuscript has improved the traceability system of agricultural products and provides a reference for the future research of stable isotopes.
