The objective of this study was to evaluate and compare the composition, physicochemical properties and in-vitro hypoglycemic effect of different fibre-rich fractions(FRFs) prepared from the seeds of passion fruits indigenous to Taiwan. This study might allow an improved use of this resource, which is currently underexploited. Since the way of processing
this agricultural byproduct might determine the functionality of food fibres, differences among the dietary fibres, alcohol-insoluble solids and water-insoluble solids, as well as the potential applications of these FRFs as fibre sources, are considered in this study.
