Determining α-tocopherol in refined bleached and deodorized palm olein using fourier transform infrared spectroscopy

Fourier transform infrared (FTIR) spectroscopy was developed for the determination of a-tocopherol in refined bleached and deodorized (RBD) palm olein. The calibration and validation samples were prepared by spiking known amount of a-tocopherol to produce a wide range of a-tocopherol up to 2000 ppm....
