Gut microbiota modulation, short-chain fatty acid (SCFA) production, and immune responses associated with structurally distinct peach pectin fractions.
Peach pectin is a promising functional polysaccharide, yet the structure-activity associations among its fractions remain poorly defined. Here, four structurally distinct peach pectin fractions, water-soluble (WSP), chelator-soluble (CSP), sodium carbonate-soluble (SSP), and an enzymatically modified fraction (ES) with...
