Automated determination of peroxides in olive oil by flow injection.
A method for the determination of the peroxide value of olive oil based on flow injection principles is proposed. The method requires no pre-treatment of samples that have undergone natural or forced oxidation as the sensitivity can be accommodated over wide margins (determination range 3.4-537 mequiv kg-1). The precision of the method, expressed as relative standard deviation, ranges from 0.7 to 2.4% and the sampling frequency is 15 h-1.
