Histamine is known to be a principal causative agent associated with marine food poisoning outbreaks worldwide, which is typically formed in the contaminated food by decarboxylation of histidine by bacterial histidine decarboxylase. Upon quantification of histamine in different food products, one can comment on the quality of the food and use it as an indicator of the good manufacturing practices and the state of preservation. The United States Food and Drug Administration (FDA) has established 50 ppm (50 mg/kg) of histamine as the chemical index for fish spoilage. Consumption of foods containing histamine higher than the permissible limit can cause serious health issues. Several methods have been developed for the determination of histamine in a variety of food products. The conventional methods for histamine detection such as thin layer chromatography, capillary zone electrophoresis, gas chromatography, colorimetry, fluorimetry, ion mobility spectrometry, high-performance liquid chromatography, and enzyme-linked immunosorbent assay (ELISA), are being used for sensitive and selective detection of histamine. However, there are a number of disadvantages associated with the conventional techniques, such as multi-step sample processing and requirement of expensive sophisticated instruments, which restrict their applications at laboratory level only. In order to address the limitations associated with the traditional methods, new approaches have been developed by various research groups. Current advances in nanomaterial-based sensing of histamine in different food products have shown significant measurement accuracy due to their high sensitivity, specificity, field deployability, cost and ease of operation. In this review, we have discussed the development of nanomaterials-based histamine sensing assays/strategies where the detection is based on optical (fluorescence, surface enhanced Raman spectroscopy (SERS), localized surface plasmon resonance) and electrochemical (impedimetric, voltammetry, potentiometric, etc.). Further, the advantages, disadvantages and future scope of the nanomaterials-based histamine sensor research are highlighted.
组胺是与世界范围内的海洋食物中毒爆发有关的主要致病因子,通常是通过细菌组氨酸脱羧酶使组氨酸脱羧形成的。在对不同食品中的组胺进行定量分析后,人们可以对食品的质量进行评价,并将其用作良好生产规范和保存状态的指标。美国食品和药物管理局(FDA)已将 50ppm(50mg/kg)组胺确定为鱼类腐败的化学指标。食用组胺含量超过允许限量的食物会导致严重的健康问题。已经开发出了多种方法来测定各种食品中的组胺。传统的组胺检测方法,如薄层色谱法、毛细管区带电泳法、气相色谱法、比色法、荧光法、离子淌度谱法、高效液相色谱法和酶联免疫吸附测定法(ELISA),用于灵敏和选择性地检测组胺。然而,传统技术存在许多缺点,例如多步样品处理和需要昂贵的复杂仪器,这限制了它们仅在实验室水平上的应用。为了解决与传统方法相关的局限性,各个研究小组已经开发了新的方法。目前,基于纳米材料的不同食品中组胺检测的新方法由于其高灵敏度、特异性、现场可部署性、成本和易于操作,在组胺检测方面取得了显著的进展。在本文中,我们讨论了基于纳米材料的组胺传感测定法/策略的发展,这些测定法基于光学(荧光、表面增强拉曼光谱(SERS)、局域表面等离子体共振)和电化学(阻抗、伏安法、电位等)。此外,还强调了基于纳米材料的组胺传感器研究的优点、缺点和未来前景。
