The toxicity of histamine has attracted numerous researchers to develop a method for histamine determination purposes. The Food and Drug Administration (FDA) unequivocally prohibits the consumption of histamine above 50 mg·kg. Thus, an innovation in histamine detection in fish has been developed in this research. The investigation of the histamine level in fish has been conducted by using an electrochemical sensor approach and producing a polymer via molecularly imprinted polymer (MIP) on a screen-printed electrode. The technique was validated by assessing the shifts in electron shifting using the cyclic voltammetry (CV) approach and electrochemical impedance spectroscopy (EIS), whereas differential pulse voltammetry (DPV) was applied to validate the sensor method. The instruments showed a linear response ranging from 1-1000 nmol·L, with a detection limit of MIP/SPE at 1.765 nmol·L and 709 nmol·L for the NIP/SPE, respectively. The sensing technique was employed to determine the histamine level in selected samples at room temperature (25°C). The outcomes of this study indicated that the validated chemical sensor allowed accurate and precise detection of fish samples and can be categorized as a simple approach. The instrument is inexpensive and suitable for on-site detection.
组胺的毒性吸引了众多研究人员开发用于组胺测定的方法。美国食品药品监督管理局(FDA)明确禁止食用组胺含量超过50 mg·kg的食品。因此,本研究开发了一种鱼类组胺检测的创新方法。通过使用电化学传感器方法并在丝网印刷电极上通过分子印迹聚合物(MIP)制备聚合物,对鱼类中的组胺水平进行了研究。通过循环伏安法(CV)和电化学阻抗谱(EIS)评估电子转移的变化来验证该技术,而差分脉冲伏安法(DPV)则用于验证传感器方法。仪器显示线性响应范围为1-1000 nmol·L,MIP/SPE的检测限为1.765 nmol·L,NIP/SPE的检测限为709 nmol·L。该传感技术用于在室温(25°C)下测定选定样品中的组胺水平。本研究结果表明,经过验证的化学传感器能够准确、精确地检测鱼类样品,可归类为一种简单的方法。该仪器价格低廉,适用于现场检测。
