  • Can DMPD be used to measure antioxidant activity?
  • A novel method for measuring the antioxidant activity using N, N-dimethyl-p-phenylenediamine (DMPD) was developed. The radical cation of this compound gives a stable colored solution and a linear inhibition of color formation can be observed in the presence of 0. 2-11 microg of TROLOX. The experimen …
  • Does DMPD work on real foods?
  • The effectiveness of the DMPD method on real foods was verified by evaluating the antioxidant ability of wine samples coming from different areas of Campania, Italy. Antioxidant capacity of wines is strictly related to the amount of phenolic compounds.
  • How does DMPD decolorize a food sample?
  • An improved decolorization method for measuring the antioxidant activity of food samples using N,N-dimethyl-p-phenylenediamine (DMPD) is developed. DMPD radical cation (DMPD •+) is generated through a reaction between DMPD and potassium persulfate and is subsequently reduced in the presence of hydrogen-donating antioxidants.
  • What is DMPD chemistry?
  • The chemistry involves the generation of a more stable DMPD radical mono-cation by a reaction with potassium persulfate. The DMPD radical cation generator does not involve Fe (II) ions, which through Fenton's Reaction could cause negative deviation in the antioxidant activity of food extracts.
