Research progress in structural and nutritional characterization and technologically processing impact on cool-season adapted oat and barley cereal kernels with wet chemistry and advanced vibrational molecular spectroscopy

Abstract

This study aims to provide research progress and update on structural, physicochemical, nutritional characteristics and technologically processing impact on cool-season adapted oat and barley cereal kernels. The study focused on cool-season adapted oats grain production and nutrition in ruminant systems and strategies to improve the utilization of the oat grain through processing techniques. The updated evaluation methods and advanced molecular spectroscopy techniques to study molecular structures with attenuated total reflectance Fourier transform infrared spectroscopy, synchrotron-based Fourier transform infrared microspectroscopy were reviewed. This study summarizes the methods and provides a potential approach on how to use vibrational molecular spectroscopy to study molecular chemistry and molecular structure and molecular nutrition interaction of grain.
