自由基与多种人类疾病的发生发展都有着密切的关系。在清除自由基的过程中，抗氧化剂发挥着重要的作用。因此，了解抗氧化剂的作用及能力就变得至关重要。

在评价抗氧化剂能力的诸多方法中，抗氧化能力ORAC（又称，氧自由基吸收能力，Oxygen Radical Absorbance Capacity）分析法，被认定为检测抗氧化剂抗氧化能力的标准方法，是目前普遍被接受的一个标准评价手段。由于该法具有接近机体生理条件、操作简单、认可度和灵敏度高、准确性和重现性佳、高通量、不易受人为因素干扰等优点，被广泛用于农业，食品，保健品，药品及医学领域。

FAQ：

1.是否可以测试冷冻保存的样品？

RE：通常适用于在 -80℃ 下保存两个月以内样品，但我们建议尽可能测试新鲜样品以获得最佳结果

2.ORAC、HORAC和TAC检测之间的区别，如何选择？

RE：所有三种测定都测量抗氧化能力，但略有不同。ORAC检测分析氧自由基的抗氧化能力；HORAC检测分析羟基自由基的抗氧化能力；TAC基于单电子转移(SET)机制和铜离子，检测总体抗氧化能力。总体而言，研究人员更偏好选择ORAC分析而不是HORAC，因为过氧自由基似乎比羟基自由基更相关。
