A new method to detect adulteration of lard in palm oil using portable NIR spectroscopy. Transflectance and transmission modes were used to characterize the effect of path length via chemometrics. The SIMCA was used for classification of pure and adulterated palm oil. The PLS-R optimized by the CARS is employed to construct the quantification model. The methodology proposed is portables, simple to implement and highly robust.
