Recent progress in structural and nutritional characterization of faba legume and use as an environment probe with vibrational spectroscopy sourced by globar and synchrotron

Abstract

This article aims to review molecular structure association with nutrient metabolism of faba bean (FB) legume as well as uses as an environment probe using vibrational molecular spectroscopy with chemometics including univariate and multivariate techniques. The review focused on molecular structural and nutritional characterization and interaction of FB-legume and updated methods with molecular spectroscopy techniques with attenuated total reflectance Fourier-transform infrared spectroscopy (FTIR), synchrotron-radiation FTIR microspectroscopy, and diffuse reflectance infrared Fourier-transform spectroscopy to study FB-legume molecular structures. This article shows how to systematically use vibrational molecular spectroscopic techniques to study molecular structure and nutrition interaction of FB-legume.
