Abstract

Virgin olive oil (VOO) is one of the most valuable vegetable oils due to its excellent nutritional value and health benefits. However, its high cost and demand make it one of the most vulnerable products to food fraud. Hence, providing rapid and effective analytical methods is essential for the quality and authenticity assessment of olive oils. Mass spectrometry (MS) has been crucial for the detection of fraudulent activities in VOO, mainly related to the verification of geographical origin or cultivar variety, the correct discrimination between different commercial categories, and adulteration with other vegetable oils or lower-quality olive oils. An ample range of MS approaches have been reported, including chromatographic systems coupled to MS, direct MS using different ionization sources, analysis with minor or even no sample preparation by ambient MS methods, and MS-based elemental analysis techniques. This review aims to provide an overview of these MS-based methods, which, often combined with suitable chemometric techniques, constitute a resourceful tool for ensuring olive oil authenticity.

使用质谱方法鉴定初榨橄榄油:综述
初榨橄榄油(VOO)具有极高的营养价值和保健功效,是最有价值的植物油之一。然而,其高昂的成本和需求量使其成为最容易受到食品欺诈的产品之一。因此,提供快速有效的分析方法对于橄榄油的质量和真实性评估至关重要。质谱法(MS)对于检测 VOO 中的欺诈活动至关重要,主要涉及地理原产地或栽培品种的验证、不同商业类别之间的正确区分以及与其他植物油或低质橄榄油的掺假。已报道的 MS 方法种类繁多,包括与 MS 相耦合的色谱系统、使用不同电离源的直接 MS、通过环境 MS 方法进行少量甚至无样品制备的分析,以及基于 MS 的元素分析技术。本综述旨在概述这些基于 MS 的方法,这些方法通常与适当的化学计量技术相结合,是确保橄榄油真实性的有效工具。
