Summary
A method for the analysis of the total tocopherols in soybean oil has been presented, and judged by distillation and other procedures is estimated to be accurate to within 10%. A discussion is made of the tocopherol to within 10%. A discussion is made of the tocopherol losses in various steps of soybean oil refining.
