A slight increase in expansion was observed when the pomace was included at low moisture levels and carrot pomace levels of 5 g/100 g, followed by a decrease in expansion at higher carrot pomace inclusions. This suggests that the carrot pomace was actively interacting with the corn starch during the extrusion process. While the precise interaction requires further research to be identified, current results might be used to create extruded products with an increased fiber content increased beta-carotene content, and increased quality within corn starch based products. Additionally, inclusion of carrot pomace into extruded products helped to identify a use for a byproduct that is currently little valorized. Further research is needed to see if this phenomenon extends to other starches and pomaces.
