In this study, FT-IR
spectroscopy was applied for rapid characterization and discrimination of
commonly consumed legumes extracted by different solvents in combination with
principal component analysis (PCA) for the first time. Dried soy bean, white
bean, chickpea, red lentil, and pinto bean were extracted by water (W), ethanol
(E), acetone/water (AW) and acetone/water/acetic acid (AA). The effect of each
solvent on different legume extracts was demonstrated by identifying the
functional groups using FT-IR spectroscopy at mid-infrared (mid-IR) range
(4000-650 cm-1) and associated with the amount of total phenolics
and other oxidation substrates in the extracts determined by Folin-Ciocalteu
method. PCA models with 2 principal components were constructed to discriminate
the different legume extracts based on FT-IR spectra and total phenolic content
(TPC). FT-IR spectra of each legume were quite different for different solvents
but almost the same for the same solvent. Each legume extracts had
significantly different TPC from each other extracted with the same or
different solvents. The highest TPC was obtained by soybeans and pinto beans
extracted with W or E and AW or AA, respectively. PCA analysis of FT-IR spectra
and TPC provided clear discrimination between the legume samples extracted with
different solvents.
