柑橘属产品真实性溯源技术研究现状及展望

近年来在柑橘的生产销售整个链条上，柑橘品种和产地的混淆造假以及以次充好等质量问题突出，所以研究柑橘属产品真实性溯源技术很有现实意义，目前已有的报道尚缺乏对柑橘属产品真实性溯源技术研究进展的系统性梳理和总结。该研究重点梳理和综述了稳定同位素和多元素分析、代谢组学分析、风味物质分析、光谱分析及核酸扩增检测等技术在柑橘属产品真实性溯源研究中的应用，并总结了各类溯源技术的优缺点，提出了目前有关湖北省脐橙的产地和品质等级鉴别研究存在的不足，同时对今后的研究方向作出了展望。以期为湖北省脐橙的产地溯源和质量监管提供一定的技术支撑。

Current Status and Prospects of Research on Authenticity Traceability Technology for Citrus Products

In recent years, in the entire chain of citrus production and sales, quality problems such as confusion and fraud of citrus variety and origin as well as shoddy products have become prominent. Therefore, it is of great practical significance to study the authenticity traceability technologies for citrus products. The existing reports still do not provide a systematic review and summary of the research progress on the authenticity traceability technologies for citrus products. This paper focuses on sorting out and reviewing the application of stable isotope and multi-element analysis, metabolomics analysis, flavor substance analysis, spectral analysis and nucleic acid amplification detection technologies in the authenticity traceability research of citrus products. The advantages and disadvantages of various traceability technologies were summarized. The deficiency of the research on the origin and quality grade identification of the navel orange in Hubei province was pointed out, while the future research direction was prospected, in order to provide certain technical support for the origin traceability and quality supervision of navel orange in Hubei Province.
