Abstract :
A method is described for the evaluation of the peroxide value (PV, meq. O2 kg−1) in olive oil. The method is based on the chemiluminogenic energy-transfer reaction of bis(2,4,6-(trichlorophenyl)oxalate (TCPO) with hydrogen peroxide or total peroxides in the presence of Mn(II) as catalyst and 9,10-dimethylanthracene as fluorophore. The procedure developed allows the evaluation of PV within the range of 0.6–100 meq. O2 kg−1 (CL intensity = 1.76 × PV (meq. O2 kg−1) + 23.2, r2 = 0.994, n = 9) and relative standard deviation within the range 1–5% by using a simple manual measurement.
