Halal authentication analysis is very important to assure pharmaceutical products free from non-halal components. Among non-halal matters, pig derivatives are frequently met in the market because pig derivatives are cheaper and easily available. Molecular spectroscopy is an ideal technique for analysis of pig derivatives in pharmaceutical products, due to its advantages, namely rapid, non-destructive, ease in operation and minimum or no sample preparation required. However, molecular spectra are sometimes overlapping and very complex which make molecular spectroscopy lack of sensitivity. Fortunately, the development of chemometrics software overcome this problem. This article reviewed the development of molecular spectroscopy (ultraviolet-visible, infrared, Raman, and nuclear magnetic resonance) in combination with chemometrics techniques for spectral treatment, classification and quantification for analysis of pig derivatives which include lard, pork and porcine gelatine for halal authentication analysis in pharmaceutical products.
Key words: molecular spectroscopy, pig derivatives, halal pharmaceutical, chemometrics.
