Geographical origin assessment of extra virgin olive oil (EVOO) is recognised worldwide as raising consumers' awareness of product authenticity and the need to protect top-quality products. The need for geographical origin assessment is also related to mandatory legislation and/or the obligations of true labelling in some countries. Nevertheless, official methods for such specific authentication of EVOOs are still missing. Among the analytical techniques useful for certification of geographical origin, nuclear magnetic resonance (NMR) and mass spectroscopy (MS), combined with chemometrics, have been widely used. This review considers published works describing the use of these analytical methods, supported by statistical protocols such as multivariate analysis (MVA), for EVOO origin assessment. The research has shown that some specific countries, generally corresponding to the main worldwide producers, are more interested than others in origin assessment and certification. Some specific producers such as Italian EVOO producers may have been focused on this area because of consumers' interest and/or intrinsic economical value, as testified also by the national concern on the topic. Both NMR- and MS-based approaches represent a mature field where a general validation method for EVOOs geographic origin assessment could be established as a reference recognised procedure.
特级初榨橄榄油（EVOO）的地理来源评估在全球范围内被认为能够提高消费者对产品真实性的认识以及保护优质产品的必要性。地理来源评估的需求还与一些国家的强制性立法和/或真实标注义务有关。然而，目前仍缺乏针对EVOO这种特定认证的官方方法。在可用于地理来源认证的分析技术中，核磁共振（NMR）和质谱（MS）结合化学计量学已被广泛使用。本综述考虑了已发表的描述这些分析方法应用的著作，这些方法由多变量分析（MVA）等统计协议支持，用于EVOO来源评估。研究表明，一些特定国家，通常是全球主要生产国，比其他国家对来源评估和认证更感兴趣。一些特定的生产商，如意大利益级初榨橄榄油生产商，可能由于消费者的兴趣和/或内在经济价值而专注于这一领域，国家对该主题的关注也证明了这一点。基于核磁共振和质谱的方法都代表了一个成熟的领域，在这个领域中，可以建立一种用于EVOO地理来源评估的通用验证方法作为公认的参考程序。
