Evaluation of a characterization method of Egyptian human mummy balms by chemometric treatments of infrared data

In the context where lengthy protocols are used to extract and characterize each substance from mummification balms using techniques such as gas chromatography mass spectrometry, this paper presents evaluation of efficiency an original method SIMPLISMA algorithm in infrared spectroscopy. This tool is a pure variable approach corresponding selection calibration variables. developed was combined with chemometric treatment (principal component analysis) interpret 47 Fourier Transform Infrared spectra human mummies’ Ancient Egypt. gave 6 their extracted concentration profiles. The first spectrum corresponded residual species, second identification polycyclic aromatic hydrocarbons, molecules which have pyrolytic origin. fourth proteins were characterized, could be considered markers good conservation individuals. fifth characterized polysaccharides. Finally, two showed same natural substance, namely fat, which, on one hand, unaltered and, other degraded fatty matter. fast, simple non-destructive allowed composition balm studied state conservation/degradation characterized. enabled presence proteins, polysaccharides matter or beeswax different states conservation/alteration
