Certified Reference Materials (CRMs) are particularly important in determining food safety, complying with phytosanitary trade restrictions, and protecting consumers. Mainly in the case of the most consumed beverages in the world, namely, coffee, cocoa, and tea, the investigation of their CRMs production provides an overview of the researched analytes and points out which areas need to be studied, which also contributes to improving their safety and quality. This review discusses aspects related to reference material (RM) preparation processes, as well as the results of homogeneity and stability tests and their application to coffee, cocoa, and tea, together with an overview of the patents developed for food RM. Results show there is a clear need to develop CRM and RM for these matrices for other analytes of interest, such as chlorogenic acids and other phenolic compounds, which will provide reliable measurements.

认证标准物质 (CRM) 在确定食品安全、遵守植物检疫贸易限制和保护消费者方面尤为重要。主要以世界上消费量最大的饮料，即咖啡、可可和茶为例，对其 CRM 生产的调查提供了研究分析物的概述，并指出了哪些领域需要研究，这也有助于提高他们的安全和质量。本综述讨论了与参考材料 (RM) 制备过程相关的方面，以及均质性和稳定性测试的结果及其在咖啡、可可和茶中的应用，以及为食品 RM 开发的专利概述。结果表明，显然需要为这些基质开发 CRM 和 RM，用于其他感兴趣的分析物，
