Employing defatted soybean meal as an original material,β-conglycinin(7S)was obtained through separation and purification,β-conglycinin was conjugated with xanthan gum(XG)under wet-heating conditions to obtain glycosylation reaction products. Box-Behnken model was used to optimize reaction conditions and analyze the emulsifying properties of optimized glycated products under various conditions. Response surface analysis revealed that the optimized conditions of glycated reaction were as follows:reaction tem...
