Ultrasonic depolymerization of pomegranate peel pectin: Effect of sonication time on antioxidant, α-amylase inhibitory, and prebiotic properties.

This study aimed to investigate the effects of ultrasonic treatment time (5-30 min) on the structural characteristics, antioxidant, α-amylase inhibitory, and prebiotic properties of pomegranate peel pectin (PPP). The extracted PPP was rich in galacturonic acid (64.27 %) and exhibited a high degree of esterification (DE, 61.
