Physicochemical and emulsifying properties of orange fibers stabilized oil-in-water emulsions

Abstract The present work aimed to evaluate the physical and techno-functional property and microstructure of freeze-dried orange pulp and peel powders modified by high-pressure homogenization (HPH) treatment, and their emulsifying properties of oil-in-water emulsions treated with HPH. For orange pulp and peel powders, HPH pre-treatment was found to significantly reduce bulk density and increase the water and oil holding capacity (P
