Depolymerized RG-I enriched pectin from citrus segment membrane modulates gut microbiota, increases SCFAs production, promotes the growth of Bifidobacterium spp., Lactobacillus spp. and Faecalibaculum spp
Mao, Guizhu; Li, Shan; Orfila, Caroline; Shen, Xuemin; Zhou, Shengyi; Linhardt, Robert J.; Ye, Xingqian; Chen, Shiguo (2019-12-01)Rhamnogalacturonan-I (RG-I)-enriched pectin (WRP) was recovered from citrus processing water by sequential acid and alkaline treatments in a previous study. RG-I-enriched pectin was proposed as a potential supplement for ... -
Extraction and characterization of RG-I enriched pectic polysaccharides from mandarin citrus peel
Zhang, Hua; Chen, Jianle; Li, Junhui; Yan, Lufeng; Li, Shan; Ye, Xingqian; Liu, Donghong; Ding, Tian; Linhardt, Robert J.; Orfila, Caroline; Chen, Shiguo (Elsevier, 2018-06-01)Pectin is extensively used as thickener and gelling agent in the food industry. Commercial pectin is usually comprised of homogalacturonans (HG) with small amount of rhamnogalacturonan-I (RG-I). However, recent studies ... -
Fast preparation of rhamnogalacturonan I enriched low molecular weight pectic polysaccharide by ultrasonically accelerated metal-free Fenton reaction
Li, Junhui; Li, Shan; Zheng, Yangfan; Zhang, Hua; Chen, Jianle; Yan, Lufeng; Ding, Tian; Linhardt, Robert J.; Orfila, Caroline; Liu, Donghong; Ye, Xingqian; Chen, Shiguo (2019-10-01)The recovery of pectic polysaccharides with high rhamnogalacturonan I (RG-I) branches from citrus canning processing water was achieved in a previous study aimed at reducing chemical oxygen demand and benefiting both process ... -
Highly branched RG-I domain enrichment are indispensable for pectin mitigating against high-fat diet-induced obesity
Zhu, Kai; Mao, Guizhu; Wu, Dongmei; Yu, Chengxiao; Cheng, Huan; Xiao, Hang; Ye, Xingqian; Linhardt, Robert J.; Orfila, Caroline; Chen, Shiguo (2020-08-12)Obesity is associated with gut microbiome dysbiosis. Our previous research has shown that highly branched rhamnogalacturonan type I (RG-I)-enriched pectin (WRP, 531.5 kDa, 70.44% RG-I, Rha/(Gal + Ara) = 20) and its ... -
Reconsidering conventional and innovative methods for pectin extraction from fruit and vegetable waste: Targeting rhamnogalacturonan I
Mao, Guizhu; Wu, Dongmei; Wei, Chaoyang; Tao, Wenyang; Ye, Xingqian; Linhardt, Robert J.; Orfila, Caroline; Chen, Shiguo (Elsevier, 2019-12-01)Background: Rhamnogalacturonan I (RG-I) is composed of a backbone of repeating disaccharide units →2)-α-L-Rhap-(1 → 4)-α-D-GalpA-(1→ with neutral sugar sidechains consisting of arabinose and galactose with variable linking ...
