Freshness is a key indicator of fish quality, making it essential to monitor throughout the food supply chain, particularly during distribution. A rapid, straightforward analytical method for assessing fish quality can provide valuable insights when products reach distribution centers or are commercialized. This study aims to develop a simplified approach based on an electronic nose (e-nose) system to evaluate the freshness of fish products within the distribution chain. The study monitored five seafood products - cuttlefish, red mullet, Atlantic cod, Atlantic mackerel, and mantis shrimp - throughout their shelf life, from arrival and packaging at the distribution centers to beyond their expiration dates. A portable electronic nose, composed by four selected metal oxide semiconductor sensors, a photoionization detector and two electrochemical cells, was used to assess the products, alongside traditional microbial analyses (Total Viable Count). The proposed method identified warning and control limits based on e-nose data, which were further confirmed by microbial testing. Control charts were developed and externally validated to assess product quality through odor intensity measurements by e-nose.
新鲜度是鱼类品质的关键指标，因此在整个食品供应链中进行监测至关重要，尤其是在分销过程中。当产品到达配送中心或商业化时，一种快速、直接的鱼类品质分析方法可以提供有价值的见解。本研究旨在开发一种基于电子鼻系统的简化方法，以评估分销链中鱼类产品的新鲜度。该研究监测了五种海鲜产品——乌贼、红鲻鱼、大西洋鳕鱼、大西洋鲭鱼和螳螂虾——在其整个货架期内的情况，从到达配送中心并包装开始，直至超过保质期。使用一个由四个选定的金属氧化物半导体传感器、一个光离子化探测器和两个电化学电池组成的便携式电子鼻， alongside traditional microbial analyses (Total Viable Count). The proposed method identified warning and control limits based on e-nose data, which were further confirmed by microbial testing. Control charts were developed and externally validated to assess product quality through odor intensity measurements by e-nose.（此处alongside至结尾这段英文表述不太准确，翻译可能会有偏差，可调整为：同时结合传统的微生物分析（总活菌数）。所提出的方法根据电子鼻数据确定了警告和控制限，并通过微生物检测进一步得到证实。通过电子鼻测量气味强度制定了控制图并进行了外部验证，以评估产品质量。）来评估这些产品，并结合传统的微生物分析（总活菌数）。所提出的方法根据电子鼻数据确定了警告和控制限，并通过微生物检测进一步得到证实。通过电子鼻测量气味强度制定了控制图并进行了外部验证，以评估产品质量。
