Chromatograms are a valuable source of information about the chemical composition of the food being analyzed. Sometimes, this information is not explicit and appears in a hidden or not obvious way. Thus, the use of chemometric tools and data-mining methods to extract it is required. The fingerprint provided by a chromatogram offers the possibility to perform both identity and quality testing of foodstuffs. This perspective is aimed at providing an updated opinion of chromatographic fingerprinting methodology in the field of food authentication. Furthermore, the limitations, its absence in official analytical methods, and the future directions of this methodology are discussed.
色谱图是分析食品化学成分的有价值信息源。有时，这些信息并不明显，以隐藏或不明显的方式出现。因此，需要使用化学计量学工具和数据挖掘方法来提取这些信息。色谱图提供的指纹图谱为食品的身份和质量检验提供了可能。本文旨在提供色谱指纹图谱方法在食品真实性领域的最新观点。此外，还讨论了该方法的局限性、在官方分析方法中的缺失以及该方法的未来发展方向。
