Spectroscopic impact on protein and carbohydrate inherent molecular structures of barley, oat and corn combined with wheat DDGS

Abstract: Abstract. The objectives of this experiment were to use non-invasive and non-destructive infrared molecular spectroscopy as a novel approach to explore and identify protein and carbohydrate molecular structure spectral features of DDGS (dried distillers grain solubles from wheat, Triticum aestivum) and its combinations with barley (Hordeum vulgare), corn (Zea mays) and oat (Avena sativa). The spectral parameters assessed in this study included amides, protein molecular structures of α-helix and β-sheet, lignin… Show more

“…The FTIR can provide information regarding the functional groups, chemical bonds, composition, structure, and quality of a product. IR spectra combined with chemometric techniques, such as Principal Component Analysis (PCA), can be used to obtain accurate dietary fiber components [10][11][12]. FTIR Spectroscopy has been used to study the relationship of feed intrinsic structures pertaining to protein molecular structures, carbohydrates, and starch matrices [10], quantitative A c c e p t e d A r t i c l e analysis of tapioca starch [13], and polysaccharide food additives [14].…”

“…By using this technique, Yu et al [ 82 ] successfully obtained the nutritional information of barley in terms of spectral and chemical characteristics and biological components distribution. Other feedstuffs like oat [ 98 ], corn [ 99 ], wheat [ 100 ], and dried distillers grains with solubles (DDGS) [ 101 ] were also analyzed using SR-IMS at the National Synchrotron Light Source in Brookhaven National Laboratory (NSLS-BNL), Advanced Light Source in Berkeley National Laboratory (ALS-BNL) and/or Canada. Light Source (CLS) synchrotron Centers.…”
