適用范圍：This International Standard specifies a method for the iodometric determination of the peroxide value ofanimal and vegetable fats and oils with a visual endpoint detection. The peroxide value is a measure of theamount of oxygen chemically bound to an oil or fat as peroxides, particularly hydroperoxides.The method is applicable to all animal and vegetable fats and oils, fatty acids and their mixtures with peroxidevalues from 0 meq to 30 meq (milliequivalents) of active oxygen per kilogram. It is also applicable tomargarines and fat spreads with varying water content. The method is not suitable for milk fats and is notapplicable to lecithins.It is to be noted that the peroxide value is a dynamic parameter, whose value is dependent upon the history ofthe sample. Furthermore, the determination of the peroxide value is a highly empirical procedure and thevalue obtained depends on the sample mass. It is stressed that, due to the prescribed sample mass, theperoxide values obtained can be slightly lower than those obtained with a lower sample mass.
