Adaptation of the AOCS official method for measuring hydroperoxides from small‐scale oil samples

An adaptation of the American Oil Chemists' Society Official Method Cd 8–53 for determining peroxides in fats and oils using a 0.5‐g sample is described. Comparisons of the Official Method and the small‐scale method were performed by analyzing soybean oil samples spiked with t‐butyl hydroperoxide and autoxidized soybean oil samples. A linear relationship between the Official Method and the small‐scale method was obtained with an R2 of 0.998. The small‐scale method is sensitive, precise, and suitable for small sample sizes and uses only about 10% of the chemicals necessary for the Official Method.
