High-value agricultural products are characterized by the geographical conditions of the production areas such as climatic and soil conditions. These products are protected by the geographical indication (GI) protection system, which has been introduced in more than 100 countries. Because GI products are expensive in the market, products are often mislabeled as GI. Thus, there is an urgent need for the development of analytical methods that enable the tracing of geographical origins of food materials. Stable isotope analysis is used to trace the geographical origin of food materials. In this study, we review the applications for tracing the geographical origin of agricultural products (especially rice, beef, and honey) focusing on an analytical method for analyzing stable isotopes (δD, δC, δN, δO, and δS).
高附加值农产品的特点是生产地区的地理条件，如气候和土壤条件。这些产品受到地理标志（GI）保护系统的保护，该系统已在 100 多个国家引入。由于 GI 产品在市场上价格昂贵，产品经常被误标为 GI。因此，迫切需要开发能够追踪食品材料地理来源的分析方法。稳定同位素分析用于追踪食品材料的地理来源。在本研究中，我们综述了用于追踪农产品（特别是大米、牛肉和蜂蜜）地理来源的应用，重点介绍了用于分析稳定同位素（δD、δC、δN、δO 和 δS）的分析方法。
