Abstract

In the field of food traceability analysis, stable isotope ratio analysis is a relatively new technology. The measurement and calibration of isotope data depends on stable isotope reference materials. The isotope reference materials commonly used are chemical matrix. These reference materials are inappropriate-especially for food matrix origin analysis. This review focuses on the research progress on stable isotope reference materials by (1) classification of stable isotope reference materials, (2) application of stable isotope reference materials, and (3) research progress of preparation of stable isotope reference materials. Selecting appropriate isotope reference materials will help improve the effectiveness of stable isotope ratio analysis in food traceability. By cooperation with different laboratories, high-quality isotope reference materials can be prepared to add new food matrix types to provide more choices for users.

摘要

在食品溯源分析领域，稳定同位素比分析是一项相对较新的技术。同位素数据的测量和校准取决于稳定的同位素参考材料。常用的同位素参考材料是化学基质。这些参考材料是不合适的——尤其是用于食品基质来源分析。本综述主要从（1）稳定同位素标准物质的分类，（2）稳定同位素标准物质的应用，（3）稳定同位素标准物质制备的研究进展来综述稳定同位素标准物质的研究进展。选择合适的同位素参考材料将有助于提高稳定同位素比率分析在食品追溯中的有效性。通过与不同实验室的合作，
