食品中麸质及其生物传感检测方法研究进展

Research Progress on Gluten in Foods and Biosensors for Its Detection

麸质引发的乳糜泻是严重的自身免疫疾病,只有终身实行严格的无麸质饮食才能缓解大多数麸质敏感人群的症状。可以即时、现场、快速地检测食品中麸质含量的传感器能够有效保障麸质敏感人群的生活质量。本文介绍了麸质敏感以及乳糜泻的发病原理,并详细阐述了麸质检测生物传感器的识别原理,最后从比色、荧光以及电化学3种不同信号输出类型出发总结了食品中麸质快速检测生物传感器的应用场景。以期为食品中麸质的快速检测传感器研究提供基础。

Gluten-induced celiac disease(CD)is a serious autoimmune disorder whose symptoms in most gluten-sensitive populations can only be relieved by strict lifelong adherence to a gluten-free diet(GFD).Sensors for immediate,on-site and quick detection of the gluten content in foods can effectively ensure the quality of life of gluten-sensitive people.In this article,gluten sensitivity and the pathogenesis of CD are introduced,and the recognition principle of gluten detection biosensors is elaborated.Finally,the application scenarios of biosensors with three different types of signal output:colorimetry,fluorescence and electrochemistry for the rapid detection of gluten in foods are summarized in order to provide a basis for research on sensors for the rapid detection of gluten in foods.
