DMDP, antioxydant capacity
Reference : KF01001
DMPD assay kit is recommended for antioxidant measurements of beverages. This kit measures the antioxidant activity of compounds that are able to transfer hydrogen atoms.
In our assay a solution of DMPD in the presence of a suitable oxidant solution, can form a stable and colored radical cation which shows an absorbance at 553 nm. Antioxidant compounds which are able to transfer a hydrogen atom to DMPD•+ quench the color and produce a discolorations of the solution which is proportional to their amount.
This reaction is rapid and the end point, which is stable, corresponds to a measure of the antioxidative efficiency.
DMPD•+(purple)+ AOH → DMPD(uncolored) +AO
