天然抗氧化剂（AOX）的化学多样性使得难以从复杂的食品/生物基质中分离、检测和量化单个抗氧化剂。此外，总的抗氧化能力往往是更有意义的健康有益的影响，因为个别抗氧化剂物种的合作行动评估。目前，由于缺乏标准的定量方法，没有单一的食品标签抗氧化剂测定。抗氧化剂测定可广泛地分类为基于电子转移（ET）和氢原子转移（HAT）的测定。由于各种测定的不同机制、氧化还原电位、pH和溶剂依赖性等，所获得的结果几乎不可比。该项目将有助于抗氧化剂的性质和相互作用的识别和量化，为抗氧化剂测定的分类及其限制和挑战提供更合理的基础，并使结果更具可比性和可理解性。在这方面，工作组成员介绍了他们在各种抗氧化剂测量方法方面的经验。
The chemical diversity of natural antioxidants (AOXs) makes it difficult to separate, detect, and quantify individual antioxidants from a complex food/biological matrix. Moreover, the total antioxidant power is often more meaningful to evaluate health beneficial effects because of the cooperative action of individual antioxidant species. Currently, there is no single antioxidant assay for food labeling because of the lack of standard quantification methods. Antioxidant assays may be broadly classified as the electron transfer (ET)- and hydrogen atom transfer (HAT)-based assays. The results obtained are hardly comparable because of the different mechanisms, redox potentials, pH and solvent dependencies, etc. of various assays. This project will aid the identification and quantification of properties and mutual effects of antioxidants, bring a more rational basis to the classification of antioxidant assays with their constraints and challenges, and make the results more comparable and understandable. In this regard, the task group members convey their own experiences in various methods of antioxidants measurement.
