Today virgin and extra-virgin olive oil (VOO and EVOO) are food with a large number of analytical tests planned to ensure its quality and genuineness. Almost all official methods demand high use of reagents and manpower. Because of that, analytical development in this area is continuously evolving. Therefore, this review focuses on analytical methods for EVOO/VOO which use fast and smart approaches based on chemometric techniques in order to reduce time of analysis, reagent consumption, high cost equipment and manpower. Experimental approaches of chemometrics coupled with fast analytical techniques such as UV-Vis spectroscopy, fluorescence, vibrational spectroscopies (NIR, MIR and Raman fluorescence), NMR spectroscopy, and other more complex techniques like chromatography, calorimetry and electrochemical techniques applied to EVOO/VOO production and analysis have been discussed throughout this work. The advantages and drawbacks of this association have also been highlighted. Chemometrics has been evidenced as a powerful tool for the oil industry. In fact, it has been shown how chemometrics can be implemented all along the different steps of EVOO/VOO production: raw material input control, monitoring during process and quality control of final product.
如今,初榨橄榄油和特级初榨橄榄油(VOO和EVOO)作为食品,需要进行大量的分析测试以确保其质量和纯度。几乎所有官方方法都需要大量使用试剂和人力。因此,该领域的分析技术不断发展。因此,本综述聚焦于基于化学计量学技术的快速、智能的EVOO/VOO分析方法,以减少分析时间、试剂消耗、高成本设备和人力。本文讨论了化学计量学的实验方法与快速分析技术(如紫外可见光谱、荧光、振动光谱(近红外、中红外和拉曼荧光)、核磁共振光谱)以及其他更复杂的技术(如色谱法、量热法和电化学技术)在EVOO/VOO生产和分析中的结合应用。这种结合的优点和缺点也得到了强调。化学计量学已被证明是石油工业的有力工具。事实上,已经表明化学计量学如何能够在EVOO/VOO生产的不同步骤中实施:原材料输入控制、过程监测和最终产品质量控制。
