Abstract

Wideline nuclear magnetic resonance (WLNMR) has been used to measure the oil content of palm mesocarp. The WLNMR was calibrated using crude palm oil and a factor to correct the signal readings due to non-oil components of mesocarp was introduced into the calibration equation. Mesocarp from Tenera palm fruits was cut and dried in either a conventional drying oven or in a microwave oven. The dried mesocarp was then ground and the NMR signal of a known amount of sample was taken after tempering at 70 degrees C for 30 minutes. The percentage of oil in the mesocarp was then calculated and this value was compared with that obtained by Soxhlet extraction. The results showed that WLNMR could be used to measure the oil content in the mesocarp rapidly and that the measuring time was much shortened with microwave drying.
