Abstract

This research was to study the potential of FT-near infrared spectroscopy (FT-NIRS) as a nondestructive way for tapioca starch investigation. The NIR spectra ranged between 1,008-2,480 nm by partial least squares (PLS) with cross-validate method analyzed by Unscrambler software version 10.1. For Lead content in tapioca starch sample ranged of 0.01 ppm to 0.50 ppm calibration and validation set n = 86 for lead contamination measurement in tapioca starch. 10 factors were studied and found that the coefficient from determination calibrations and validation set were 0.96 and 0.90 respectively. The accuracy indicated how close the measured value was from its actual value. The SEC and the SEP was 0.02 and 0.4% with the Bias 1.4x10-9. The experiment indicated that Pb content measured with NIRS in tapioca starch considered to be used to acquire standard method. NIRS required no sample destruction method and applied for a fast inspection.
