Abstract
In this study, the influences of the addition of different mung bean skin insoluble dietary fiber (MIDF) contents (0–10 wt%) on the properties of dough and gluten proteins were investigated. With the addition of MIDF, the elastic modulus, viscosity modulus, and loss factor of the dough all showed increasing trends. Additionally, the bound water content significantly increased by 15.37 % (P < 0.05), while the weakly bound water content decreased by 14.32 % (P < 0.05), indicating the migration of weakly bound water to bound water. These changes resulted in increased hardness, chewiness, and gumminess of the dough. Furthermore, the incorporation of MIDF significantly reduced the SS content in gluten by 43.01 % (P < 0.05). Concurrently, the secondary structure of gluten protein transformed from ordered structures, such as α-helices and β-sheets, to disordered structures, such as random coils and β-turns, thereby loosening the protein skeleton structure and affecting the gluten network. These results established a theoretical foundation for the development and enhancement of functional foods enriched with dietary fiber.
