Microbial food safety is a persistent and exacting global issue due to the multiplicity and complexity of foods and food production systems. Foodborne illnesses caused by foodborne bacterial pathogens frequently occur, thus endangering the safety and health of human beings. Factors such as pretreatments, that is, culturing, enrichment, amplification make the traditional routine identification and enumeration of large numbers of bacteria in a complex microbial consortium complex, expensive, and time-consuming. Therefore, the need for rapid point-of-use detection systems for foodborne bacterial pathogens with high sensitivity and specificity is crucial in food safety control. Hyperspectral imaging (HSI) as a powerful testing technology provides a rapid, nondestructive approach for pathogen detection. This article reviews some fundamental information about HSI, including instrumentation, data acquisition, image processing, and data analysis-the current application of HSI for the detection, classification, and discrimination of various foodborne pathogens. The merits and demerits of HSI for pathogen detection as well as current and future trends are discussed. Therefore, the purpose of this review is to provide a brief overview of HSI, and further lay emphasis on the emerging trend and importance of this technique for foodborne pathogen detection.
微生物食品安全是一个持久且严格的全球性问题，这是由于食品和食品生产系统的多样性和复杂性所致。食源性细菌病原体引起的食源性疾病经常发生，从而危及人类的安全和健康。预处理因素，例如培养、富集、扩增，使得对复杂微生物群落中大量细菌进行传统常规鉴定和计数变得复杂、昂贵且耗时。因此，迫切需要具有高灵敏度和特异性的用于食源性细菌病原体的快速现场检测系统，这在食品安全控制中至关重要。高光谱成像（HSI）作为一种强大的检测技术，为病原体检测提供了一种快速、无损的方法。本文综述了 HSI 的一些基本信息，包括仪器、数据采集、图像处理和数据分析——HSI 当前在检测、分类和区分各种食源性病原体方面的应用。讨论了 HSI 用于病原体检测的优缺点以及当前和未来的趋势。因此，本综述的目的是简要概述 HSI，并进一步强调该技术在食源性病原体检测中的新兴趋势和重要性。
