Linear sweep voltammetry has been applied to the measurement of the tocopherol content of vegetable oils. Separate anodic voltammetric peaks are obtained for CY-, 7-and &tocopherol. The p-tocopherol peak is superimposed on that of ?-tocopherol. Under the same conditions, butylated hydroxyanisole (BHA) may be determined in vegetable oil at concentrations exceeding 0.001%. However, 6-tocopherol interferes. Propyl gallate (PG) may be determined in lard at concentrations greater than about 0.001%. The procedures are quite rapid. The entire operation from sample weighing to acquisition of the voltammogram requires only about ten minutes.
