A new processing technology of dietary fiber from the peel of passionfruit (Pasiflora edulis) was developed. The main factors influencing the bleaching of the dietary fiber were investigated. The results showed that factors influencing the bleaching of the dietary fiber were bleaching temperature (T), pH, bleaching bine (H), hydrogen peroxide concentration (W), sequestrant concentration (GC3). Sensory evaluation was best when T was 60 ℃, pH 8, H' 2.5 hours, W' 6 %, and GC3 1% in orthogonal experiments.
