Abstract

Ultrasonic-assisted method was used to extract dietary fiber from honey pomelo endocarp to study its physicochemical and functional properties. The results showed that dietary fiber product was yellow which had uniform color. It had good palate and soon be soften after chewing. The dietary fiber (DF) content was 89.7%. Water holding capacity (WHC), oil holding capacity (OHC) and swelling capacity (SWC) were 1057.6%, 87.7% and 1024.0% respectively. Water-solubility (WS) was 22.4% and nitrite scavenging rate was 31.7% Its cation exchange capacity was better.
