A company that produces natural antioxidant extracts wishes to evaluate the effectiveness of two of their new products: extract A and extract B. To this end, they decide to evaluate their antiradical activity using the DPPH° test by establishing, for each extract, the reaction kinetics for different concentrations. From the resulting curves, the percentage of residual DPPH° on the plateau is determined. The values obtained are reported in the following table:
|Concentration in antioxidant extract (g/L)||EXTRACT A: residual DPPH° at the plateau (%)||EXTRACT B: residual DPPH° at the plateau (%)|
