Abstract :

Total antioxidant capacity (TAC) as the cumulative activity of antioxidants in a sample is an important parameter in the analysis of biological or food matrices. Therefore, it is very important to evaluate the total antioxidant capacity of the substances in the diet and biological fluids. Based on this, many methods check their antioxidant capacity and effectiveness in different conditions. However, there is often no strong correlation between the capacities measured on the same materials with different methods, which is due to the variety of active materials, mechanisms and different characteristics such as different types of antioxidants, the presence of other interfering substances in the sample, lack of participation of antioxidants are used in the method reaction. In recent years, different analytical methods based on nanoparticles have been developed to determine the antioxidant capacity of foods and plant materials.In these measurement methods, nanoparticles such as gold, silver, iron oxide, manganese oxide, quantum dots and cerium oxide have been used. In this article, we review some of the researches conducted in the field of total antioxidant capacity measurement.
