摘要:

在新陈代谢过程中, 机体会产生大量以自由基为主要形式的氧化活性物质, 而抗氧化剂可以通过电子转移的方式捕获并中和自由基, 从而有效抵御自由基引起的细胞损害, 以保障和维护人体健康. 食品作为人体外源性抗氧化剂的重要来源可以有效补充因体内代谢及体液排出而损失的抗氧化物质, 因此对食品中抗氧化物质消除自由基的能力即抗氧化能力的测定和评价具有重要意义. 光电化学技术作为一种简单快捷、 低成本、 低背景且高灵敏度的测定方法, 能够有效克服光学法、 色谱法和电化学法等传统测试手段在抗氧化容量分析中的不足. 本文综述了基于半导体及其复合材料的光电化学传感平台的构建及食品体系抗氧化容量分析的研究进展, 评论了多种检测体系的特点并对其研究前景进行了展望.

Abstract:

In the process of metabolism, the body will produce a large number of oxidation active substances with free radicals as the main formation, and antioxidants can capture and neutralize free radicals in the form of electron transfer, so as to protect the cell from damage, prevent and retard the oxidative deterioration of food. Therefore, it is of great significance for the determination and evaluation of antioxidants capacitance in foods. As a low-cost, simple, quick and sensitive method, photoelectrochemical(PEC) technology can overcome the shortcomings of conventional methods, such as optical method, chromatographic method and electrochemical method. The design of photocatalysis materials is the key of the PEC platform. The review concludes with the progress of the photoelectrochemical platform based on semiconductor materials applied in the analysis of antioxidant capacity in food and the characteristics of various detection systems. In addition, the future research directions are also proposed.
