Abstract:
Highland barley glutenin (HBG) was glycosylated with inulin (INU) under hygrothermal conditions to produce highland barley glutenin-inulin (HBG-INU) complexes, and the effects of different glycosylation ratios on the structural, physicochemical, and functional properties of HBG-INU were investigated. In the range of 8:0-8:5 glycosylation ratios, HBG-INU exhibited an excellent glycosylation effect, with a maximum grafting degree of 25.86 ± 0.71%, and distinct structural changes of HBG-INU from loose lumpy accumulation to flat and smooth rod-like structure. Both the FT-IR analysis and fluorescence intensity (FI) analyses of HBG-INU confirmed these glycosylation-induced structural changes. At the glycosylation ratio of 8:4, HBG-INU exhibited significantly improved physicochemical and functional properties, and the maximums of solubility, foaming capacity (FC) and emulsifying activity index (EAI) were 96.10 ± 2.67%, 119.67 ± 5.51% and 12.10 ± 0.04 m2/g, respectively. All these structural, physicochemical and functional results reveal the successful and excellent glycosylation effects of HBG-INU complexes.
