ammonium thiocyanate. The peroxide value was determined by
reading the absorbance at 500 nm, 3 min after colour development
with 0.1 ml FeCl2. All test data are the average of triplicate analyses.
The percentage of inhibition of peroxidation (%) was calculated
as follows:
Inhibition of peroxidation ð%Þ
¼
1 ðabsorbance of sample at 500 nmÞ
ðabsorbance of control at 500 nmÞ
