Liquid foods play important roles in the development of human culture due to their own peculiarities. Mid-infrared (MIR) spectroscopy combines several advantages such as non-invasive operation and high-efficiency detection and is thus proposed to be a prospective alternative to conventional techniques for food quality assessment. However, no reviews on MIR spectroscopic analysis of liquid food products are reported. This review summarizes the recent research progress of MIR chemical sensing methods for determinations of the authenticity and related quality attributes of liquid foods (such as milk, edible oils, alcoholic beverages, honeys, and vegetable and fruit juices). The characteristics and applications of MIR spectroscopic technique in tandem with chemometrics, along with the major challenges and future prospects, are discussed. MIR spectroscopy has great potential to fulfill the need of food industry for quality and authenticity analysis of liquid foods. Nevertheless, further measurements and analyses based on the existing results of food inspection are still required. It is believed that this review will be an effective signpost for scholars in related research fields to study the comprehensive quality of liquid food products.

液体食品由于其自身的特性而在人类文化的发展中起着重要的作用。中红外（MIR）光谱技术结合了诸如无创操作和高效检测等多项优势，因此被提议作为食品质量评估常规技术的替代方法。但是，没有关于液态食品的MIR光谱分析的评论。这篇综述总结了用于确定液体食品（如牛奶，食用油，酒精饮料，蜂蜜以及蔬菜和果汁）的真实性和相关质量属性的MIR化学传感方法的最新研究进展。讨论了中红外光谱技术与化学计量学相结合的特点和应用，以及主要挑战和未来前景。MIR光谱具有巨大的潜力，可以满足食品工业对液态食品的质量和真实性分析的需求。尽管如此，仍需要根据现有食品检查结果进行进一步的测量和分析。相信这篇评论将为相关研究领域的学者研究液态食品的综合质量提供有效的路标。
