基于1H NMR的代谢组学技术在食品掺假及溯源分析中的研究进展

受产地、加工、贮存以及运输过程中的各种影响，引起食品的复杂性和可变性，导致食品的掺假及溯源分析具有一定的挑战性。现有的食品掺假溯源方法主要集中在理化测试及分子生物学技术等方面，相关鉴别的准确性有待提高。基于核磁共振氢谱（1H NMR）的代谢组学技术与多元统计分析相结合，可以完整地描述食品的整体特征，收集食品的产地、品质等信息，近来在食品领域应用较为广泛，已成为食品质量分析和溯源等的有力工具。本文阐述了1H NMR组学技术在农产食品掺假及溯源分析中的应用进展，在概述1H NMR技术原理的基础上，针对1H NMR与化学计量学分析方法的结合及其应用进行了介绍，对其在典型性食品的掺假及产地溯源上的研究进行了概括总结，旨在为1H NMR组学技术在食品品质分析中的研究及应用提供理论参考。

Research Progress of 1H NMR-based Metabonomics for Food Adulteration and Traceability Analysis

Due to various influences in the process of origin, processing, storage and transportation, food products are complex and changeable. Therefore, it is challenging to analyze and determine the adulteration and traceability of food. The existing food adulteration traceability methods mainly focus on physical and chemical testing and molecular biology technology, and the accuracy of relevant identification needs to be improved. The combination of metabonomics technology based on 1H NMR and multivariate statistical analysis can describe the overall characteristics of food and collect food origin and quality information. Recently, it has been widely used in the food field and has become a powerful tool for food adulteration and traceability analysis. Therefore, this paper describes the progress of 1H NMR omics technology in the adulteration and traceability analysis of food. Based on the overview of the principle of 1H NMR technology, the combination and application of 1H NMR and chemometrics analysis are introduced, and the applications of adulteration and traceability in typical food products are summarized, providing theoretical reference for the research and application of 1H NMR omics technology in food quality analysis.
