Depolymerized RG-I-enriched pectin from citrus segment membranes modulates gut microbiota, increases SCFA production, and promotes the growth ofBifidobacteriumspp.,Lactobacillusspp. andFaecalibaculumspp.

Rhamnogalacturonan-I-enriched pectin (WRP) was recovered from citrus segment membrane. WRP can stimulate the growth of beneficial microbiome. In addition, the effect was enhanced by free-radical depolymerizing of WRP into DWRP.
