The assessment of interactions between natural antioxidants and other food matrix components represents the main step in the investigation of total antioxidant properties, in terms of potential health benefits. The diversity of chemical structures of natural compounds, besides their possible interactions, as well as the biological role and different modes of action makes it difficult to assess a single and reliable procedure for the evaluation of antioxidant activity. Today, much attention is given to the distinction between extractable and non-extractable antioxidants as a key tool in the description of the nutritional and healthy properties of food matrices. The starting point for the investigation of antioxidant effects of food extracts is the analysis of antioxidant properties of pure compounds and their interactions. Another complementary approach could be represented by the study of how different biologically active compound-rich extracts contribute to the total antioxidant capacity.
就潜在的健康益处而言,评估天然抗氧化剂与其他食品基质成分之间的相互作用是研究总抗氧化特性的主要步骤。天然化合物化学结构的多样性,除了它们可能的相互作用之外,以及生物作用和不同的作用方式,使得评估单一且可靠的抗氧化活性评估程序变得困难。如今,人们非常关注可提取和不可提取抗氧化剂之间的区别,将其作为描述食品基质营养和健康特性的关键工具。研究食品提取物抗氧化作用的起点是分析纯化合物的抗氧化特性及其相互作用。另一种互补方法可以是研究不同富含生物活性化合物的提取物如何对总抗氧化能力做出贡献。
