A method has been developed, utilizing the Technicon AutoAnalyzer, to determine the tocopherol content of deodorized oil. The chemistry of the Emmerie‐Engel method, based upon the reduction of ferric chloride, is utilized in the development of this automated method. The tocopherol content of soybean oil is measured relative to a standard sample of d‐α‐tocopherol. The tocopherol content as measured by this method will include any other reducing substances present in the sample to be analyzed. The standard deviation, as derived from a pooling of the variances of four deodorized soybean oil samples is ± 0.0023% at the 0.1% level.
