This study revealed that the edible passion fruit seed was rich in insoluble FRFs (IDF, AIS and WIS) which
were mainly composed of cellulose, pectic substances and hemicellulose. These FRFs had water- and oilholding
capacities comparable with those of cellulose, while their bulk densities and cation-exchange capacities were significantly higher than those of cellulose. All insoluble FRFs showed significant (P
