In this study, an extrusion technology was successfully applied
to orange pomace to increase its SDF fraction under optimal conditions.
The increase in SDF content in the extrusion was mainly contributed
by redistribution of IDF to SDF. In addition, the
physicochemical properties including WHC, WSI, swelling property,
and cation-exchange capacity of extruded orange pomace
were improved compared to the unextruded sample. Extruded
orange pomace enriched SDF content could be a potential food
ingredient for use in goods such as bakery products, soups,
beverages.
