摘要:
This International Standard specifies a method for the iodometric determination of the peroxide value of animal and vegetable fats and oils with a visual endpoint *** peroxide value is a measure of the amount of oxygen chemically bound to an oil or fat as peroxides,particularly *** method is applicable to all animal and vegetable fats and oils,fatty acids and their mixtures with peroxide values from 0 meq to 30 meq(milliequivalents) of active oxygen per *** is also applicable to margarines and fat spreads with varying water *** method is not suitable for milk fats and is not applicable to *** is to be noted that the peroxide value is a dynamic parameter,whose value is dependent upon the history of the ***,the determination of the peroxide value is a highly empirical procedure and the value obtianed depends on the sample *** is stressed that,due to the prescribed sample mass,the peroxide values obtained can be slightly lower than those obtained with a lower sample mass.
