Electron beam irradiation as a physical modification approach to enhance the functional potential of dietary fiber in wheat bran.

Wheat bran (WB) is a fiber-rich byproduct with limited functionality due to its compact structure and low bioavailability of bioactive compounds. Electron beam irradiation (EBI) is a clean, non-thermal technology with potential to enhance the structural and functional properties of WB. This study investigated the effects of EBI (5-25 kGy) on the structural, physicochemical, and functional properties of WB.
