Determination of enantiomeric ratios in food and beverages is a research area of great interest because enantiomers can exhibit different biological activities. Chiral analysis can provide valuable information about food safety, bioactivity, quality and traceability. In this work, the potential of separation techniques such as liquid chromatography, gas chromatography, supercritical fluid chromatography and capillary electrophoresis for chiral analysis of food is reviewed. The analysis of enantiomers based on other chiral methodologies such as countercurrent chromatography, sensors, biosensors and direct mass spectrometry (MS) analysis is also included. The present review article provides an updated perspective on the importance of chiral analysis in food matrices and beverages covering the period from February 2017 to July 2019, following the previous work published in this journal on the same topic (G. D'Orazio et al., TrAC-Trends in Analytical Chemistry 96 (2017) 151-171).

食品和饮料中对映体比例的确定是一个非常受关注的研究领域，因为对映体可以表现出不同的生物活性。手性分析可以提供有关食品安全性，生物活性，质量和可追溯性的有价值的信息。在这项工作中，回顾了分离技术（例如液相色谱，气相色谱，超临界流体色谱和毛细管电泳）在食品手性分析中的潜力。还包括基于其他手性方法的对映体分析，例如逆流色谱法，传感器，生物传感器和直接质谱（MS）分析。本评论文章提供了有关2017年2月至2019年7月期间手性分析在食品基质和饮料中的重要性的最新观点，G.D'Orazio等人，TrAC-Trends in Analytical Chemistry 96（2017）151-171）。
