Effect of Plastein Reaction on Physical and Chemical Characteristics of Corn Glutelin Peptides and Quality of Chiffon Cake

Corn glutelin hydrolysate (CGH) was prepared by alkaline protease hydrolysis of corn glutelin and further modified by histidine (His) and tryptophan (Trp) through the Plastein reaction, obtaining His-fortified CGH (His-CGH) and Trp-fortified CGH (Trp-CGH). The functional properties (solubility, foaming capacity, and emulsifying activity) of the modified peptides were analyzed. The corresponding modifiers were added to baked products to evaluate potential application in the baking field. The...
