Today, one of the world's biggest problems is the assurance of food integrity from farm to fork. Economically motivated food adulteration and food authenticity problems are increasing daily with considerable health and economic effects. Early detection and prevention of food integrity-related problems could be provided by the application of effective on-site food analysis technologies. FTIR spectroscopy coupled with chemometrics can be used for the rapid quality control of a wide variety of food products with fast, high-throughput, accurate and nondestructive analysis advantages. In particular, hand-held and portable FTIR instruments have the potential to surveil food quality and food safety in various critical segments of the food supply chain. In this review, we explore the abilities of hand-held and portable FTIR spectrometers combined with multivariate statistics to conduct a quality evaluation of various food products in terms of food adulteration and authenticity issues. An examination of the literature showed that comparable results were obtained based on detection limits, correlation coefficient (R) values, standard error values and discrimination power by using both portable/hand-held FTIR spectrometers and benchtop FTIR spectrometers. In conclusion, this review highlights the potential usefulness of portable and hand-held FTIR spectrometers combined with chemometrics for maintaining the food quality through the presentation of various applications that may shed light for on-site food control at any point of the food supply chain.
如今，全球最大的问题之一是从农场到餐桌确保食品的完整性。受经济利益驱动，食品掺假和食品真实性问题日益严重，对健康和经济造成了相当大的影响。通过应用有效的现场食品分析技术，可以及早发现和预防与食品完整性相关的问题。傅里叶变换红外（FTIR）光谱结合化学计量学可用于快速、高通量、准确且无损分析的优势，对各种食品进行快速质量控制。特别是，手持式和便携式 FTIR 仪器有可能在食品供应链的各个关键环节监测食品质量和食品安全。在这篇综述中，我们探讨了手持式和便携式 FTIR 光谱仪结合多元统计，在食品掺假和真实性问题方面对各种食品进行质量评估的能力。对文献的研究表明，使用便携式/手持式 FTIR 光谱仪和台式 FTIR 光谱仪，基于检测限、相关系数（R）值、标准误差值和判别能力，均能获得可比的结果。总之，本综述通过介绍各种应用，突出了便携式和手持式 FTIR 光谱仪结合化学计量学在通过保持食品质量方面的潜在用途，可为食品供应链的任何点提供现场食品控制的思路。
